Clindamycin (Monograph)

Brand names: Cleocin HCL, Cleocin Pediatric, Cleocin Phosphate
Drug class: Lincomycins

Medically reviewed by Drugs.com on Apr 10, 2024. Written by ASHP.

Warning

    Diarrhea and Colitis
  • Clostridium difficile-associated diarrhea and colitis (CDAD; also known as antibiotic-associated diarrhea and colitis or pseudomembranous colitis) has been reported with nearly all anti-infectives, including clindamycin, and may range in severity from mild to life-threatening. Anti-infectives alter normal flora of the colon and may permit overgrowth of C. difficile.

  • Because clindamycin has been associated with severe colitis (potentially fatal), it should be reserved for treatment of serious infections when less toxic anti-infectives are inappropriate. Do not use for nonbacterial infections. (See Uses.)

  • C. difficile produces toxins A and B which contribute to development of CDAD. Hypertoxin-producing strains cause increased morbidity and mortality since they may be refractory to anti-infectives and may require colectomy. CDAD must be considered in all patients who present with diarrhea following anti-infective use. Careful medical history is necessary since CDAD has been reported to occur 2 months or longer after administration of anti-infectives.

  • If CDAD is suspected or confirmed, ongoing anti-infective use not directed against C. difficile may need to be discontinued. Institute appropriate fluid and electrolyte management, protein supplementation, anti-infective treatment of C. difficile, and surgical evaluation as clinically indicated. (See Superinfection/Clostridium difficile-associated Diarrhea and Colitis [CDAD] under Cautions.)

Introduction

Antibacterial; lincosamide antibiotic derived from lincomycin.

Uses for Clindamycin

Acute Otitis Media (AOM)

Alternative for treatment of AOM [off-label].

When anti-infectives indicated, AAP recommends high-dose amoxicillin or amoxicillin and clavulanate as drugs of first choice for initial treatment of AOM; certain cephalosporins (cefdinir, cefpodoxime, cefuroxime, ceftriaxone) recommended as alternatives for initial treatment in penicillin-allergic patients without a history of severe and/or recent penicillin-allergic reactions.

AAP states clindamycin (with or without a third generation cephalosporin) is a possible alternative for treatment of AOM in patients who fail to respond to initial treatment with first-line or preferred alternatives.

May be effective in infections caused by penicillin-resistant Streptococcus pneumoniae; may not be effective against multidrug-resistant S. pneumoniae and usually inactive against Haemophilus influenzae. If used for retreatment of AOM, consider concomitant use of an anti-infective active against H. influenzae and Moraxella catarrhalis (e.g., cefdinir, cefixime, cefuroxime).

Bone and Joint Infections

Treatment of serious bone and joint infections (including acute hematogenous osteomyelitis) caused by susceptible Staphylococcus aureus or anaerobes.

Adjunct in the surgical treatment of chronic bone and joint infections caused by susceptible bacteria.

Gynecologic Infections

Treatment of serious gynecologic infections (e.g., endometritis, nongonococcal tubo-ovarian abscess, pelvic cellulitis, postsurgical vaginal cuff infection) caused by susceptible anaerobes.

Treatment of pelvic inflammatory disease (PID); used in conjunction with other anti-infectives. When a parenteral regimen is indicated for treatment of PID, IV clindamycin in conjunction with IV or IM gentamicin is one of several recommended regimens.

Intra-abdominal Infections

Treatment of serious intra-abdominal infections (e.g., peritonitis, intra-abdominal abscess) caused by susceptible anaerobes.

No longer routinely recommended for treatment of intra-abdominal infections because of increasing incidence of Bacteroides fragilis resistant to clindamycin.

Pharyngitis and Tonsillitis

Alternative for treatment of pharyngitis and tonsillitis [off-label] caused by susceptible S. pyogenes (group A β-hemolytic streptococci; GAS) in patients who cannot receive β-lactam anti-infectives.

AAP, IDSA, and AHA recommend a penicillin regimen (10 days of oral penicillin V or oral amoxicillin or single dose of IM penicillin G benzathine) as treatment of choice for S. pyogenes pharyngitis and tonsillitis; other anti-infectives (oral cephalosporins, oral macrolides, oral clindamycin) recommended as alternatives in penicillin-allergic patients.

Respiratory Tract Infections

Treatment of serious respiratory tract infections (e.g., pneumonia, empyema, lung abscess) caused by susceptible S. aureus, S. pneumoniae, other streptococci, or anaerobes.

IDSA and ATS consider clindamycin an alternative for treatment of community-acquired pneumonia (CAP) caused by S. pneumoniae or S. aureus (methicillin-susceptible strains) in adults. IDSA also considers clindamycin an alternative for treatment of CAP caused by S. pneumoniae, S. pyogenes, or S. aureus in pediatric patients. For treatment of pneumonia caused by methicillin-resistant S. aureus (MRSA; also known as oxacillin-resistant S. aureus or ORSA), IDSA states clindamycin is one of several options, unless the strain is resistant to clindamycin.

For information on treatment of CAP, consult current IDSA clinical practice guidelines available at [Web].

Septicemia

Treatment of serious septicemia caused by S. aureus, streptococci, or anaerobes.

Skin and Skin Structure Infections

Treatment of serious skin and skin structure infections caused by susceptible staphylococci, S. pneumoniae, other streptococci, or anaerobes. One of several preferred drugs for treatment of staphylococcal and streptococcal skin and skin structure infections, including those known or suspected to be caused by susceptible MRSA.

Treatment of clostridial myonecrosis [off-label] (gas gangrene) caused by Clostridium perfringens or other Clostridium; used in conjunction with or as alternative to penicillin G.

Alternative for treatment of infected human or animal (e.g., dog, cat, reptile) bite wounds; used in conjunction with either an extended-spectrum cephalosporin or co-trimoxazole. Purulent bite wounds usually are polymicrobial and broad-spectrum anti-infective coverage recommended. Nonpurulent infected bite wounds usually caused by staphylococci and streptococci, but can be polymicrobial.

For information on treatment of skin and skin structure infections, consult current IDSA clinical practice guidelines available at [Web].

Actinomycosis

Alternative to penicillin G or ampicillin for treatment of actinomycosis [off-label], including infections caused by Actinomyces israelii.

Anthrax

Alternative for treatment of anthrax [off-label].

Component of multiple-drug parenteral regimens recommended for treatment of inhalational anthrax that occurs as the result of exposure to B. anthracis spores in the context of biologic warfare or bioterrorism. Initiate treatment with IV ciprofloxacin or doxycycline and 1 or 2 other anti-infective agents predicted to be effective (e.g., chloramphenicol, clindamycin, rifampin, vancomycin, clarithromycin, imipenem, penicillin, ampicillin); if meningitis is established or suspected, use IV ciprofloxacin (rather than doxycycline) and chloramphenicol, rifampin, or penicillin.

Based on in vitro data, possible alternative for postexposure prophylaxis following a suspected or confirmed exposure to aerosolized anthrax spores (inhalational anthrax) when drugs of choice (ciprofloxacin, doxycycline) not tolerated or cannot be used.

Babesiosis

Treatment of babesiosis caused by Babesia microti or other Babesia.

Regimens of choice for babesiosis are clindamycin in conjunction with quinine or atovaquone in conjunction with azithromycin. Clindamycin and quinine regimen generally preferred for severe babesiosis caused by B. microti and infections caused by M. divergens, B. duncani, B. divergens-like organisms, or B. venatorum.

Also consider exchange transfusions in severely ill patients with high levels of parasitemia (>10%), significant hemolysis, or compromised renal, hepatic, or pulmonary function.

Bacterial Vaginosis

Treatment of bacterial vaginosis (formerly called Haemophilus vaginitis, Gardnerella vaginitis, nonspecific vaginitis, Corynebacterium vaginitis, or anaerobic vaginosis).

CDC and others recommend treatment of bacterial vaginosis in all symptomatic women (including pregnant women).

Regimens of choice are 7-day regimen of oral metronidazole; 5-day regimen of intravaginal metronidazole gel; or 7-day regimen of intravaginal clindamycin cream. Alternative regimens are 2- or 5-day regimen of oral tinidazole; 7-day regimen of oral clindamycin; or 3-day regimen of intravaginal clindamycin suppositories. Preferred regimens for pregnant women are the oral or intravaginal metronidazole or clindamycin regimens.

Regardless of treatment regimen used, relapse or recurrence is common; retreatment with the same or an alternative regimen (e.g., oral therapy when topical was used initially) may be used in such situations.

Malaria

Treatment of uncomplicated malaria caused by chloroquine-resistant Plasmodium falciparum or when plasmodial species not identified. Used in conjunction with oral quinine; not effective alone.

CDC and others state treatments of choice for uncomplicated chloroquine-resistant P. falciparum malaria or when plasmodial species not identified are the fixed combination of atovaquone and proguanil hydrochloride (atovaquone/proguanil); the fixed combination of artemether and lumefantrine (artemether/lumefantrine); or a regimen of oral quinine in conjunction with doxycycline, tetracycline, or clindamycin. When a quinine regimen used, concomitant doxycycline or tetracycline generally preferred over concomitant clindamycin (more efficacy data available regarding regimens that include a tetracycline); clindamycin preferred in young children or pregnant women who should not receive tetracyclines.

Treatment of severe malaria caused by P. falciparum; used in conjunction with IV quinidine gluconate initially and then with oral quinine when an oral regimen tolerated. Severe malaria requires aggressive antimalarial treatment initiated as soon as possible after diagnosis.

Assistance with diagnosis or treatment of malaria is available from CDC Malaria Hotline at 770-488-7788 or 855-856-4713 from 9:00 a.m. to 5:00 p.m. Eastern Standard Time or CDC Emergency Operation Center at 770-488-7100 after hours and on weekends and holidays.

Pneumocystis jirovecii Pneumonia

Treatment of Pneumocystis jirovecii (formerly Pneumocystis carinii) pneumonia (PCP); used in conjunction with primaquine. Designated an orphan drug by FDA for treatment of PCP associated with acquired immunodeficiency syndrome (AIDS).

Co-trimoxazole is drug of choice for treatment of mild, moderate, or severe PCP, including PCP in HIV-infected adults, adolescents, and children. Regimen of primaquine and clindamycin is an alternative for treatment of mild, moderate, or severe PCP in HIV-infected adults and adolescents who have had an inadequate response to co-trimoxazole or when co-trimoxazole is contraindicated or not tolerated. Although data not available regarding use in children, regimen of primaquine and clindamycin also can be considered an alternative to co-trimoxazole in HIV-infected children based on data in adults.

Regimen of primaquine and clindamycin not recommended for prevention of initial episodes (primary prophylaxis) or long-term suppressive or chronic maintenance therapy (secondary prophylaxis) of PCP. Co-trimoxazole is drug of choice for primary and secondary prophylaxis of PCP in HIV-infected adults, adolescents, and children.

Toxoplasmosis

Alternative for treatment of toxoplasmosis caused by Toxoplasma gondii in immunocompromised adults, adolescents, and children (including HIV-infected patients); used in conjunction with pyrimethamine (and leucovorin). CDC, NIH, IDSA, and AAP recommend pyrimethamine (and leucovorin) used in conjunction with sulfadiazine as regimen of choice for initial treatment of toxoplasmosis in HIV-infected adults and adolescents, treatment of congenital toxoplasmosis, and treatment of acquired CNS, ocular, or systemic toxoplasmosis in HIV-infected children. Pyrimethamine (and leucovorin) used in conjunction with clindamycin is the preferred alternative in those unable to tolerate sulfadiazine or who fail to respond to initial regimen.

Alternative for long-term suppressive or chronic maintenance therapy (secondary prophylaxis) to prevent relapse of toxoplasmosis in HIV-infected adults, adolescents, and children who have completed treatment for the disease; used in conjunction with pyrimethamine and leucovorin. Pyrimethamine (and leucovorin) used in conjunction with sulfadiazine is regimen of choice for secondary prophylaxis. Pyrimethamine (and leucovorin) used in conjunction with clindamycin is one of several alternatives in those who cannot tolerate sulfonamides.

Perioperative Prophylaxis

Alternative for perioperative prophylaxis to reduce the incidence of infections in patients undergoing certain clean, contaminated surgeries when drugs of choice (e.g., cefazolin, cefuroxime, cefoxitin, cefotetan) cannot be used because of hypersensitivity to β-lactam anti-infectives.

Experts state clindamycin or vancomycin is a reasonable alternative for perioperative prophylaxis in patients allergic to β-lactam anti-infectives who are undergoing cardiac surgery (e.g., CABG, valve repairs, cardiac device implantation), neurosurgery (e.g., craniotomy, spinal and CSF-shunting procedures, intrathecal pump placement), orthopedic surgery (e.g., spinal procedures, hip fracture, internal fixation, total joint replacement), non-cardiac thoracic surgery (e.g., lobectomy, pneumonectomy, lung resection, thoracotomy), vascular surgery (e.g., arterial procedures involving a prosthesis, the abdominal aorta, or a groin incision), lower extremity amputation for ischemia, or certain transplant procedures (e.g., heart and/or lung). Clindamycin also a reasonable alternative for perioperative prophylaxis in such patients undergoing head and neck surgery (e.g., incisions through oral or pharyngeal mucosa).

For procedures that might involve exposure to enteric gram-negative bacteria, experts state that clindamycin or vancomycin used in conjunction with an aminoglycoside (e.g., amikacin, gentamicin, tobramycin), aztreonam, or a fluoroquinolone is a reasonable alternative in patients allergic to β-lactam anti-infectives. These procedures include certain GI and biliary tract procedures (e.g., esophageal or gastroduodenal procedures, appendectomy for uncomplicated appendicitis, surgery involving unobstructed small intestine, colorectal procedures), gynecologic and obstetric surgery (e.g., cesarean section, hysterectomy), urologic procedures involving an implanted prosthesis, and certain transplant procedures (e.g., liver, pancreas and/or kidney).

Prevention of Bacterial Endocarditis

Alternative to amoxicillin or ampicillin for prevention of α-hemolytic (viridans group) streptococcal bacterial endocarditis in penicillin-allergic patients undergoing certain dental procedures (i.e., procedures that involve manipulation of gingival tissue, the periapical region of teeth, or perforation of oral mucosa) or certain invasive respiratory tract procedures (i.e., procedures involving incision or biopsy of respiratory mucosa) who have certain cardiac conditions that put them at highest risk of adverse outcomes from endocarditis.

Anti-infective prophylaxis solely for prevention of bacterial endocarditis no longer recommended by AHA for patients undergoing GU or GI procedures.

Cardiac conditions identified by AHA as associated with highest risk of adverse outcomes from endocarditis: Prosthetic cardiac valves or prosthetic material used for cardiac valve repair, previous infective endocarditis, certain forms of congenital heart disease, and cardiac valvulopathy after cardiac transplantation.

Consult most recent AHA recommendations for additional information on which cardiac conditions are associated with highest risk of adverse outcomes from endocarditis and specific recommendations regarding use of prophylaxis to prevent endocarditis in these patients.

Prevention of Perinatal Group B Streptococcal Disease

Alternative to penicillin G or ampicillin for prevention of perinatal group B streptococcal (GBS) disease in penicillin-allergic pregnant women at high risk for anaphylaxis if they receive a β-lactam anti-infective.

Intrapartum anti-infective prophylaxis to prevent early-onset neonatal GBS disease is administered to women identified as GBS carriers during routine prenatal GBS screening performed at 35–37 weeks of gestation during the current pregnancy and to women who have GBS bacteriuria during the current pregnancy, a previous infant with invasive GBS disease, unknown GBS status with delivery at <37 weeks of gestation, amniotic membrane rupture for ≥18 hours, or intrapartum temperature of ≥38°C.

Penicillin G is drug of choice and ampicillin is the preferred alternative for anti-infective prophylaxis of GBS. Cefazolin is recommended for GBS prophylaxis in penicillin-allergic women who do not have immediate-type penicillin hypersensitivity; clindamycin or, alternatively, vancomycin is recommended for such prophylaxis in penicillin-allergic women at high risk for anaphylaxis (e.g., history of anaphylaxis, angioedema, respiratory distress, or urticaria after receiving a penicillin or cephalosporin).

Consider that S. agalactiae (group B streptococci; GBS) with in vitro resistance to clindamycin has been reported with increasing frequency; perform in vitro susceptibility tests of clinical isolates obtained during GBS prenatal screening. GBS isolates susceptible to clindamycin but resistant to erythromycin in vitro should be evaluated for inducible clindamycin resistance. If GBS isolate is intrinsically resistant to clindamycin, demonstrates inducible resistance to clindamycin, or if susceptibility to clindamycin and erythromycin are unknown, use vancomycin instead of clindamycin for GBS prophylaxis.

Consult most recent CDC and AAP guidelines for additional information on prevention of perinatal GBS disease.

Clindamycin Dosage and Administration

Administration

Administer orally, IM, or by intermittent or continuous IV infusion. Do not administer by rapid IV injection.

In the treatment of serious anaerobic infections, parenteral route usually used initially but may be switched to oral route when warranted by patient’s condition. In clinically appropriate circumstances, oral route may be used initially.

Clindamycin phosphate ADD-Vantage vials and commercially available premixed solutions of clindamycin phosphate in 5% dextrose should be used only for IV infusion.

For solution and drug compatibility information, see Compatibility under Stability.

Oral Administration

Clindamycin hydrochloride capsules and clindamycin palmitate hydrochloride oral solution can be administered without regard to food.

To avoid the possibility of esophageal irritation, administer clindamycin hydrochloride capsules with a full glass of water. Swallow capsules whole; do not use in pediatric patients unable to swallow capsules.

Reconstitution

Reconstitute clindamycin palmitate hydrochloride powder (granules) for oral solution by adding 75 mL of water to the 100-mL bottle. Add a large portion of the water initially and shake bottle vigorously; add remainder of the water and shake bottle until solution is uniform. The resulting oral solution contains 75 mg of clindamycin/5 mL.

IM Injection

For IM injection, administer clindamycin phosphate solution containing 150 mg of clindamycin per mL undiluted.

Single IM doses should not exceed 600 mg.

IV Infusion

Prior to IV infusion, clindamycin phosphate solutions (including solutions provided in ADD-Vantage vials) must be diluted with a compatible IV solution to a concentration ≤18 mg/mL.

Usually administered by intermittent IV infusion. Alternatively, may be given by continuous IV infusion in adults after first dose is given by rapid IV infusion. (See Table 1.)

Commercially available premixed solutions of clindamycin phosphate in 5% dextrose are administered only by IV infusion. Discard premixed solution if container seal is not intact or leaks are found or if the solution is not clear. Do not introduce additives into the container. Do not use flexible containers in series connections with other plastic containers; such use could result in air embolism from residual air being drawn from the primary container before administration of the fluid from the secondary container is complete.

Dilution

Clindamycin phosphate solution containing 150 mg of clindamycin per mL: Dilute appropriate dose in a compatible IV infusion solution and administer using the recommended rate of administration. (See Rate of Administration under Dosage and Administration.)

Clindamycin phosphate solution provided in ADD-Vantage vials: Dilute according to directions provided by the manufacturer. ADD-Vantage vials are for IV infusion only.

Clindamycin phosphate pharmacy bulk package: Dilute in a compatible IV infusion solution; not intended for direct IV infusion. Bulk package is intended for use only under a laminar flow hood. Entry into the vial should be made using a sterile transfer set or other sterile dispensing device, and the contents dispensed in aliquots using appropriate technique; multiple entries with a syringe and needle are not recommended because of the increased risk of microbial and particulate contamination. After entry into the bulk package vial, use entire contents promptly; discard any unused portion within 24 hours after initial entry.

Rate of Administration

Give intermittent IV infusions over a period of at least 10–60 minutes and at a rate ≤30 mg/minute. Give no more than 1.2 g by IV infusion in a single 1-hour period.

Dilute 300-mg doses in 50 mL of compatible diluent and infuse over 10 minutes; dilute 600-mg doses in 50 mL of diluent and infuse over 20 minutes; dilute 900-mg doses in 50–100 mL of diluent and infuse over 30 minutes; dilute 1.2-g doses in 100 mL of diluent and infuse over 40 minutes.

As an alternative to intermittent IV infusions in adults, the drug can be given by continuous IV infusion after an initial dose is given by IV infusion over 30 minutes. (See Table 1.)

Cautions for Clindamycin

Contraindications

Warnings/Precautions

Warnings

Superinfection/Clostridium difficile-associated Diarrhea and Colitis (CDAD)

Possible emergence and overgrowth of nonsusceptible organisms, particularly yeasts. Institute appropriate therapy if superinfection occurs.

Treatment with anti-infectives alters normal colon flora and may permit overgrowth of Clostridium difficile. C. difficile infection (CDI) and C. difficile-associated diarrhea and colitis (CDAD; also known as antibiotic-associated diarrhea and colitis or pseudomembranous colitis) reported with nearly all anti-infectives, including clindamycin, and may range in severity from mild diarrhea to fatal colitis. C. difficile produces toxins A and B which contribute to development of CDAD; hypertoxin-producing strains of C. difficile are associated with increased morbidity and mortality since they may be refractory to anti-infectives and colectomy may be required.

Consider CDAD if diarrhea develops during or after therapy and manage accordingly. Obtain careful medical history since CDAD may occur as late as ≥2 months after anti-infective therapy discontinued.

If CDAD suspected or confirmed, discontinue anti-infectives not directed against C. difficile whenever possible. Initiate appropriate supportive therapy (e.g., fluid and electrolyte management, protein supplementation), anti-infective therapy directed against C. difficile (e.g., metronidazole, vancomycin), and surgical evaluation as clinically indicated.

Patients with Meningitis

Do not use for treatment of meningitis; clindamycin diffusion into CSF inadequate for treatment of CNS infections.

Sensitivity Reactions

Anaphylactic shock and anaphylactoid reactions with hypersensitivity reported.

Other severe hypersensitivity reactions, including severe skin reactions such as toxic epidermal necrolysis, drug reaction with eosinophilia and systemic symptoms (DRESS), and Stevens-Johnson syndrome, reported and have been fatal in some cases. Acute generalized exanthematous pustulosis and erythema multiforme also reported.

Generalized mild to moderate morbilliform-like (maculopapular) rash, vesiculobullous rash, urticaria, pruritus, angioedema, and rare instances of exfoliative dermatitis reported.

Some commercially available clindamycin capsules (e.g., Cleocin HCl 75- and 150-mg capsules) contain the dye tartrazine (FD&C yellow No. 5), which may cause allergic reactions including bronchial asthma in susceptible individuals. Although the incidence of tartrazine sensitivity is low, it frequently occurs in patients sensitive to aspirin.

Prior to initiation of clindamycin, make careful inquiry regarding prior hypersensitivity to drugs and other allergens. Use with caution in atopic individuals.

If anaphylactic or severe hypersensitivity reactions occur, permanently discontinue clindamycin and institute appropriate therapy as necessary.

General Precautions

Selection and Use of Anti-infectives

To reduce development of drug-resistant bacteria and maintain effectiveness of clindamycin and other antibacterials, use only for treatment or prevention of infections proven or strongly suspected to be caused by susceptible bacteria.

When selecting or modifying anti-infective therapy, use results of culture and in vitro susceptibility testing. In the absence of such data, consider local epidemiology and susceptibility patterns when selecting anti-infectives for empiric therapy.

Surgical procedures should be performed in conjunction with clindamycin therapy when indicated.

History of GI Disease

Use with caution in patients with a history of GI disease, particularly colitis. (See Superinfection/Clostridium difficile-associated Colitis under Cautions.)

Cardiovascular Effects

Rapid IV administration has caused cardiopulmonary arrest and hypotension.

Laboratory Monitoring

Monitor liver function, renal function, and CBCs periodically during prolonged therapy.

Specific Populations

Pregnancy

Reproduction studies in rats and mice have not revealed evidence of teratogenicity.

In clinical trials that included pregnant women, systemic clindamycin administered during second and third trimesters was not associated with increased frequency of congenital abnormalities. No adequate and well-controlled studies to date using clindamycin in pregnant women during first trimester of pregnancy.

Use during pregnancy only when clearly needed.

Clindamycin phosphate injection contains benzyl alcohol as a preservative; benzyl alcohol can cross the placenta. (See Pediatric Use under Cautions.)

Lactation

Distributed into milk; potentially can cause adverse effects on GI flora of breast-fed infants.

Manufacturer states clindamycin use in the mother is not a reason to discontinue breast-feeding; however, it may be preferable to use an alternate anti-infective.

If used in a breast-feeding mother, monitor infant for possible adverse effects on GI flora, including diarrhea and candidiasis (thrush, diaper rash) or, rarely, blood in the stool indicating possible antibiotic-associated colitis.

Consider benefits of breast-feeding and importance of clindamycin to the woman; also consider potential adverse effects on breast-fed child from the drug or from the underlying maternal condition.

Pediatric Use

Monitor organ system functions when used in pediatric patients (birth to 16 years of age).

Each mL of clindamycin phosphate injection contains 9.45 mg of benzyl alcohol. Large amounts of benzyl alcohol (i.e., 100–400 mg/kg daily) have been associated with toxicity (potentially fatal “gasping syndrome”) in neonates. Although amount of benzyl alcohol in recommended IM or IV clindamycin dosages are substantially lower than amounts reported in association with “gasping syndrome,” minimum amount of benzyl alcohol at which toxicity may occur unknown. Risk of benzyl alcohol toxicity depends on quantity administered and capacity of liver and kidneys to detoxify the chemical. Premature and low-birthweight infants may be more likely to develop toxicity.

Geriatric Use

Insufficient experience in patients ≥65 years of age to determine whether they respond differently than younger adults.

Clinical experience indicates that C. difficile-associated diarrhea and colitis seen in association with anti-infectives may occur more frequently and be more severe in geriatric patients (>60 years of age). Carefully monitor geriatric patients for development of diarrhea (e.g., changes in bowel frequency).

Hepatic Impairment

Moderate to severe liver disease may result in prolonged clindamycin half-life, but accumulation may not occur.

Periodically monitor liver enzymes in patients with severe hepatic impairment.

Common Adverse Effects

GI effects (nausea, vomiting, diarrhea, abdominal pain, tenesmus); rash; local reactions (pain, induration, sterile abscess with IM and thrombophlebitis, erythema, pain and swelling with IV).

Drug Interactions

Substrate of CYP isoenzyme 3A4 and, to a lesser extent, CYP3A5.

Moderate inhibitor of CYP3A4 in vitro; does not inhibit CYP1A2, 2C9, 2C19, 2E1, or 2D6.

Drugs Affecting Hepatic Microsomal Enzymes

CYP3A4 or 3A5 inhibitors: Possible increased plasma concentrations of clindamycin. Monitor for adverse effects if used with potent CYP3A4 inhibitor.

CYP3A4 or 3A5 inducers: Possible decreased plasma concentrations of clindamycin. Monitor for loss of clindamycin effectiveness if used with potent CYP3A4 inducer.

Clindamycin Pharmacokinetics

Absorption

Bioavailability

Clindamycin hydrochloride capsules: Approximately 90% of an oral dose rapidly absorbed from GI tract; peak serum concentrations attained within 45 minutes.

Clindamycin palmitate hydrochloride oral solution: Rapidly hydrolyzed in GI tract to active clindamycin.

Clindamycin phosphate: Following IM or IV administration, rapidly hydrolyzed in plasma to active clindamycin.

Following IM administration of clindamycin phosphate, peak serum concentrations occur within 3 hours in adults and 1 hour in children.

Food

Administration of clindamycin hydrochloride capsules or clindamycin palmitate hydrochloride oral solution with food does not appreciably affect absorption or serum concentrations of the drug.

Distribution

Extent

Widely distributed into body tissues and fluids, including saliva, ascites fluid, peritoneal fluid, pleural fluid, synovial fluid, bone, and bile.

Clinically important concentrations not attained in CSF, even in the presence of inflamed meninges.

Readily crosses the placenta; cord blood concentrations may be up to 50% of concurrent maternal blood concentrations.

Distributed into milk.

Plasma Protein Binding

93%.

Elimination

Metabolism

Partially metabolized to bioactive and inactive metabolites.

In vitro studies indicate clindamycin is predominantly metabolized by CYP3A4 and, to a lesser extent, by CYP3A5 to the major bioactive metabolite clindamycin sulfoxide and minor metabolite N-desmethylclindamycin.

Elimination Route

Excreted in urine, bile, and feces.

Approximately 10% of an oral dose excreted in urine and 3.6% excreted in feces as active drug and metabolites; remainder is excreted as inactive metabolites.

Not appreciably removed by hemodialysis or peritoneal dialysis.

Half-life

Adults and children: 2–3 hours.

Geriatric adults: Approximately 4 hours (range: 3.4–5.1 hours) following oral administration.

Neonates: Serum half-life depends on gestational and chronologic age and body weight. Reportedly averages 8.7 or 3.6 hours in premature or full-term neonates, respectively, and is about 3 hours in infants 4 weeks to 1 year of age.

Special Populations

Pharmacokinetics after IV administration in healthy older adults (61–79 years of age) similar to younger adults (18–39 years of age).

Serum half-life increased slightly in patients with markedly reduced renal or hepatic function.
