Antibiotics (applies to Helidac) colitis

Major Potential Hazard, Moderate plausibility. Applicable conditions: Colitis/Enteritis (Noninfectious), Colitis/Enteritis (Noninfectious)

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.

Nitroimidazoles (applies to Helidac) blood dyscrasias

Major Potential Hazard, Low plausibility. Applicable conditions: History - Blood Dyscrasias, Bone Marrow Depression/Low Blood Counts

The use of nitroimidazoles (e.g., metronidazole, tinidazole) has rarely been associated with hematologic adverse effects such as mild, transient leukopenia, thrombocytopenia, and bone marrow aplasia. The manufacturers recommend that therapy with nitroimidazoles be administered cautiously in patients with evidence of or a history of blood dyscrasias, and that total and differential leukocyte counts be performed before and after treatment with these drugs, particularly in patients receiving repeated courses of therapy.

Nitroimidazoles (applies to Helidac) neurologic toxicity

Major Potential Hazard, Moderate plausibility. Applicable conditions: CNS Disorder, Peripheral Neuropathy

The use of nitroimidazoles (e.g., metronidazole, tinidazole) has been associated with the development of nervous system toxicity including convulsive seizures and dose-related peripheral neuropathy, the latter characterized primarily by numbness or paresthesia of an extremity. Persistent peripheral neuropathy has been reported in some patients treated for prolonged periods. Other neurologic adverse effects include vertigo, incoordination, ataxia, confusion, agitation, hallucinations, and depression. Therapy with nitroimidazoles should be administered cautiously in patients with or predisposed to seizures or other nervous system abnormalities. Nitroimidazole therapy should be discontinued promptly if neurologic disturbances occur.

Salicylates (applies to Helidac) Reye's syndrome

Major Potential Hazard, High plausibility. Applicable conditions: Influenza, Varicella-Zoster

The use of salicylates, primarily aspirin, in children with varicella infections or influenza-like illnesses has been associated with an increased risk of Reye's syndrome. Although a causal relationship has not been established, the majority of evidence to date seems to support the association. Most authorities, including the American Academy of Pediatrics Committee on Infectious Diseases, recommend avoiding the use of salicylates in children and teenagers with known or suspected varicella or influenza and during presumed outbreaks of influenza. If antipyretic or analgesic therapy is indicated under these circumstances, acetaminophen may be an appropriate alternative. The same precautions should also be observed with related agents such as salicylamide or diflunisal because of their structural and pharmacological similarities to salicylate.

Metronidazole (applies to Helidac) alcoholism

Moderate Potential Hazard, Moderate plausibility.

Nitroimidazoles (e.g., metronidazole, tinidazole) may inhibit alcohol dehydrogenase and occasionally precipitate a disulfiram-like reaction in patients who consume alcohol while being treated. Symptoms may include nausea, vomiting, flushing, sweating, headache, abdominal cramps, and hypotension. Patients should be instructed to avoid alcohol-containing products during nitroimidazole therapy and for at least 48 to 72 hours after the last dose. Therapy with nitroimidazoles should be administered cautiously in patients who might be prone to acute alcohol intake. An alternative therapy may be appropriate.

Metronidazole (applies to Helidac) liver disease

Moderate Potential Hazard, High plausibility.

Metronidazole is extensively metabolized by the liver to both pharmacologically active and inactive compounds. The plasma clearance of metronidazole may be decreased and the half-life prolonged in patients with impaired hepatic function. Therapy with metronidazole should be administered cautiously at reduced dosages in patients with severe liver disease.

Metronidazole (applies to Helidac) sodium

Moderate Potential Hazard, High plausibility. Applicable conditions: Congestive Heart Failure, Hypertension, Fluid Retention, Hypernatremia

Flagyl I.V. RTU (brand of metronidazole ready-to-use injection) contains 14 mEq of sodium per each 500 mg dose of metronidazole. The sodium content should be considered when this product is used in patients with conditions that may require sodium restriction, such as congestive heart failure, hypertension, and fluid retention.

Salicylates (applies to Helidac) coagulation

Moderate Potential Hazard, Moderate plausibility. Applicable conditions: Bleeding, Coagulation Defect, Thrombocytopathy, Thrombocytopenia, Vitamin K Deficiency

All salicylates can interfere with the action of vitamin K and induce a dose-dependent alteration in hepatic synthesis of coagulation factors VII, IX and X. At usual recommended dosages, a slight increase in prothrombin time (PT) may occur. Therapy with salicylates, especially if given in high dosages, should be administered cautiously in patients with significant active bleeding or a hemorrhagic diathesis, including hemostatic and/or coagulation defects associated with hemophilia, vitamin K deficiency, hypoprothombinemia, thrombocytopenia, thrombocytopathy, or severe hepatic impairment. The same precaution should also be observed with the use of related agents such as salicylamide because of their structural and pharmacological similarities to salicylate.

Tetracyclines (applies to Helidac) hepatotoxicity

Moderate Potential Hazard, Moderate plausibility. Applicable conditions: 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.

Tetracyclines (applies to Helidac) renal dysfunction

Moderate Potential Hazard, High plausibility.

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.

Tetracyclines (oral) (applies to Helidac) esophageal irritation

Moderate Potential Hazard, Moderate plausibility. Applicable conditions: 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.
