Drug interactions
Moderate drug interactions
Moderate:
minocycline cloxacillin
Applies to: Myrac (minocycline) and cloxacillin
Talk to your doctor before using minocycline together with cloxacillin. Combining these medications may reduce the effectiveness of cloxacillin. Your doctor may be able to prescribe alternatives that do not interact. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
Food/lifestyle interactions
Moderate food/lifestyle interactions
Moderate:
cloxacillin Food/Lifestyle
Applies to: cloxacillin
You may experience reduced absorption of cloxacillin in the presence of food. The effectiveness of the antibiotic may be reduced. Cloxacillin should be administered one hour before or two hours after meals. This will make it easier for your body to absorb the medication. Penicillin V and amoxicillin are not affected by food and may be given without regard to meals.
Moderate:
minocycline multivitamins with minerals
Applies to: Myrac (minocycline)
In general, multivitamins with minerals and minocycline should not be taken orally at the same time. Products that contain aluminum, calcium, iron, magnesium, zinc and/or other minerals may interfere with the absorption of minocycline into the bloodstream and reduce its effectiveness in treating your infection. If possible, it may be best to avoid taking multivitamins with minerals while you are being treated with minocycline. Otherwise, you should separate their dosing times by as much as possible, usually at least 2 to 4 hours. Talk to your healthcare provider if you are unsure whether your medications contain something that could potentially interact or if you have questions on how to take this or other medications you are prescribed. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
Disease interactions
11 potential interactions Applies to: 10 conditions, including High Blood Pressure, Heart Failure, Fluid Retention, Liver Disease, and Thrombocytopenia.
Esophageal Obstruction
Moderate:
Myrac
The minocycline in Myrac has a moderate potential interaction with Esophageal Obstruction.
The use of oral tetracycline capsules and tablets has been associated with esophageal irritation and ulceration in patients who ingested the drug without sufficient fluid shortly before bedtime. Therapy with solid formulations of tetracyclines should preferably be avoided in patients with esophageal obstruction, compression or dyskinesia. If the drugs are used, patients should be advised not to take the medication just before retiring and to drink fluids liberally.
Fluid Retention
Moderate:
cloxacillin
Cloxacillin has a moderate potential interaction with Fluid Retention.
Each 250 mg capsule of cloxacillin sodium contains approximately 14 mg (0.6 mEq) of sodium, and each teaspoonful of the 125 mg/5 mL oral solution contains approximately 11 mg (0.48 mEq) of sodium. The sodium content should be considered in patients with conditions that may require sodium restriction, such as congestive heart failure, hypertension, and fluid retention.
Heart Failure
Moderate:
cloxacillin
Cloxacillin has a moderate potential interaction with Heart Failure.
Each 250 mg capsule of cloxacillin sodium contains approximately 14 mg (0.6 mEq) of sodium, and each teaspoonful of the 125 mg/5 mL oral solution contains approximately 11 mg (0.48 mEq) of sodium. The sodium content should be considered in patients with conditions that may require sodium restriction, such as congestive heart failure, hypertension, and fluid retention.
High Blood Pressure
Moderate:
cloxacillin
Cloxacillin has a moderate potential interaction with High Blood Pressure.
Each 250 mg capsule of cloxacillin sodium contains approximately 14 mg (0.6 mEq) of sodium, and each teaspoonful of the 125 mg/5 mL oral solution contains approximately 11 mg (0.48 mEq) of sodium. The sodium content should be considered in patients with conditions that may require sodium restriction, such as congestive heart failure, hypertension, and fluid retention.
Hypernatremia
Moderate:
cloxacillin
Cloxacillin has a moderate potential interaction with Hypernatremia.
Each 250 mg capsule of cloxacillin sodium contains approximately 14 mg (0.6 mEq) of sodium, and each teaspoonful of the 125 mg/5 mL oral solution contains approximately 11 mg (0.48 mEq) of sodium. The sodium content should be considered in patients with conditions that may require sodium restriction, such as congestive heart failure, hypertension, and fluid retention.
Liver Disease
Moderate:
Myrac
The minocycline in Myrac has a moderate potential interaction with Liver Disease.
The use of tetracyclines has rarely been associated with hepatotoxicity. Histologic fatty changes of the liver, elevated liver enzymes, and jaundice have been reported, primarily in patients treated with large doses of intravenous tetracycline hydrochloride (no longer available in the U.S.) but also in patients receiving high oral doses of these drugs. Therapy with tetracyclines should be administered cautiously in patients with preexisting liver disease or biliary obstruction. Reduced dosages may be appropriate, particularly with minocycline and doxycycline, since the former is metabolized by the liver and the latter undergoes enterohepatic recycling. Liver function tests are recommended prior to and during therapy, and the concomitant use of other potentially hepatotoxic drugs should be avoided.
Neutropenia
Major:
cloxacillin
Cloxacillin has a major potential interaction with Neutropenia.
The use of penicillinase-resistant penicillins has been associated with adverse hematologic effects, including neutropenia, leukopenia, granulocytopenia and thrombocytopenia, particularly when given in high parenteral dosages. Agranulocytosis and prolonged bleeding time have been reported rarely. Therapy with penicillinase-resistant penicillins should be administered cautiously in patients with preexisting blood dyscrasias or bone marrow depression, and hematopoietic function should be monitored. Blood counts with differential should be performed prior to initiation of therapy and 1 to 3 times weekly during therapy. Hematologic abnormalities are generally reversible and resolve within several days to two weeks following discontinuation of therapy.
Noninfectious Colitis
Major:
cloxacillin
Cloxacillin has a major potential interaction with Noninfectious Colitis.
Clostridioides difficile-associated diarrhea (CDAD), formerly pseudomembranous colitis, has been reported with almost all antibacterial drugs and may range from mild diarrhea to fatal colitis. The most common culprits include clindamycin and lincomycin. Antibacterial therapy alters the normal flora of the colon, leading to overgrowth of C difficile, whose toxins A and B contribute to CDAD development. Morbidity and mortality are increased with hypertoxin-producing strains of C difficile; these infections can be resistant to antimicrobial therapy and may require colectomy. CDAD must be considered in all patients who present with diarrhea after antibacterial use. Since CDAD has been reported to occur more than 2 months after antibacterial use, careful medical history is necessary. Therapy with broad-spectrum antibacterials and other agents with significant antibacterial activity should be administered cautiously in patients with history of gastrointestinal disease, particularly colitis; pseudomembranous colitis (generally characterized by severe, persistent diarrhea and severe abdominal cramps, and sometimes associated with the passage of blood and mucus), if it occurs, may be more severe in these patients and may be associated with flares in underlying disease activity. Antibacterial drugs not directed against C difficile may need to be stopped if CDAD is suspected or confirmed. Appropriate fluid and electrolyte management, protein supplementation, antibacterial treatment of C difficile, and surgical evaluation should be started as clinically indicated.

Renal Dysfunction
Moderate:
Myrac
The minocycline in Myrac has a moderate potential interaction with Renal Dysfunction.
Tetracyclines (except doxycycline) are eliminated by the kidney to various extent. Patients with renal impairment may be at greater risk for tetracycline-associated hepatic and/or renal toxicity (increased BUN with consequent azotemia, hyperphosphatemia, and acidosis) due to decreased drug clearance. Therapy with tetracyclines should be administered cautiously at reduced dosages in patients with renal impairment. Clinical monitoring of renal and liver function is recommended, and serum tetracycline levels may be necessary during prolonged therapy.
Thrombocytopenia
Major:
cloxacillin
Cloxacillin has a major potential interaction with Thrombocytopenia.
The use of penicillinase-resistant penicillins has been associated with adverse hematologic effects, including neutropenia, leukopenia, granulocytopenia and thrombocytopenia, particularly when given in high parenteral dosages. Agranulocytosis and prolonged bleeding time have been reported rarely. Therapy with penicillinase-resistant penicillins should be administered cautiously in patients with preexisting blood dyscrasias or bone marrow depression, and hematopoietic function should be monitored.
