Disease interactions

19 potential interactions Applies to: 19 conditions, including High Blood Pressure, Heart Failure, Peripheral Neuropathy, Hypokalemia, and Anemia.

Alcoholism

Moderate:

Flagyl

The metroNIDAZOLE in Flagyl has a moderate potential interaction with Alcoholism.

Nitroimidazoles (e.g., metronidazole, tinidazole, fexinidazole, secnidazole) may inhibit alcohol dehydrogenase and occasionally precipitate a disulfiram-like reaction in patients who consume alcohol while being treated. Symptoms may include abdominal cramps, nausea, vomiting, headache, flushing, rash, weakness, diarrhea, abdominal pain, dizziness, sweating, and hypotension. Patients should be instructed to avoid alcohol-containing products during nitroimidazole therapy and for at least 48 hours (fexinidazole, secnidazole) to 72 hours (metronidazole, tinidazole) 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.

Anemia

Moderate:

amphotericin b

amphotericin B has a moderate potential interaction with Anemia.

Intravenous amphotericin B therapy may depress erythropoietin and red blood cell production and commonly causes a normocytic, normochromic anemia. Although the anemia is well tolerated by most patients and usually reverses completely within several months of stopping therapy, it may be problematic in patients with preexisting anemia. Intravenous therapy with amphotericin B should be administered cautiously in anemic patients or those predisposed to anemia. Frequent monitoring of blood counts and hemoglobin concentrations are recommended.

Bone Marrow Depression/Low Blood Counts

Major:

Flagyl

The metroNIDAZOLE in Flagyl has a major potential interaction with 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.

Central Nervous System Disorders

Major:

Flagyl

The metroNIDAZOLE in Flagyl has a major potential interaction with Central Nervous System Disorders.

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.

Electrolyte Abnormalities

Moderate:

amphotericin b

amphotericin B has a moderate potential interaction with Electrolyte Abnormalities.

Intravenously administered amphotericin B is nephrotoxic and may commonly cause hypo- or hyperkalemia, hypomagnesemia, and hypocalcemia secondary to renal impairment. Renal function and serum electrolytes should be closely monitored in all patients receiving intravenous therapy with amphotericin B, but in particular, those with preexisting renal and/or electrolyte abnormalities. Mineral and electrolyte supplementation is frequently required. Complications of electrolyte imbalances include muscle weakness, tetany, seizures and cardiac disturbances. Amphotericin B-related electrolyte abnormalities generally improve following cessation of therapy but may persist long after because of the drug's long terminal elimination half-life.

Noninfectious Colitis

Major:

Flagyl

The metroNIDAZOLE in Flagyl 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.

Peripheral Neuropathy

Major:

Flagyl

The metroNIDAZOLE in Flagyl has a major potential interaction with 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.

Renal Dysfunction

Moderate:

amphotericin b

amphotericin B has a moderate potential interaction with Renal Dysfunction.

Intravenously administered amphotericin B is nephrotoxic and may commonly cause decreased renal function and abnormalities including azotemia, hypo- and hyperkalemia, hypomagnesemia, hyposthenuria, renal tubular acidosis, and nephrocalcinosis. Renal function should be closely monitored in all patients receiving intravenous therapy with amphotericin B but in particular, patients with preexisting renal impairment. Dosage reductions are recommended. Serum creatinine, BUN, potassium and magnesium levels should be evaluated frequently, and dosing adjusted or discontinued accordingly.
