Uses
A large body of clinical data exists to support use of tinidazole for infections from amoebae, giardia, and trichomonas, just like metronidazole. Tinidazole may be a therapeutic alternative in the setting of metronidazole intolerance. Tinidazole may also be used to treat a variety of other bacterial infections (e.g., as part of combination therapy for Helicobacter pylori eradication protocols).[2]
Side effects
Drinking alcohol while taking tinidazole causes an unpleasant disulfiram-like reaction, which includes nausea, vomiting, headache, increased blood pressure, flushing, and shortness of breath.
Half-life
Elimination half-life is 13.2 ± 1.4 hours. Plasma half-life is 12 to 14 hours.
