Tinidazole Disease Interactions

There are 5 disease interactions with tinidazole.


Nitroimidazoles (applies to tinidazole) blood dyscrasias

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

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 tinidazole) 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.

Nitroimidazoles (applies to tinidazole) alcoholism

Moderate Potential Hazard, Moderate plausibility.

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.

Tinidazole (applies to tinidazole) hemodialysis

Moderate Potential Hazard, High plausibility.

The clearance of tinidazole is significantly increased during hemodialysis; the half-life is reduced from 12 hours to 4.9 hours. During a 6-hour hemodialysis session, approximately 43% of the amount present in the body is eliminated. If this drug is administered on the same day as and prior to hemodialysis, an additional dose of tinidazole equivalent to one-half the recommended dose should be administered after the end of the hemodialysis session.

Tinidazole (applies to tinidazole) liver disease

Moderate Potential Hazard, Moderate plausibility.

There are no data on the pharmacokinetics of tinidazole in patients with liver dysfunction. Reduced metabolic elimination of metronidazole (a chemically-related nitroimidazole) has been reported in patients with liver dysfunction. Usual recommended doses of tinidazole should be administered cautiously in patients with liver dysfunction.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
