What should you know about tinidazole for trichomoniasis?

Trichomoniasis is a sexually transmitted infection caused by a parasite. It may cause vaginal discharge, itching, irritation, discomfort with urination or no noticeable symptoms. Tinidazole works against the organism, but it does not prevent a new infection after treatment.

A clinician may choose tinidazole after considering test results, pregnancy, breastfeeding, liver problems, allergies and other medicines. Symptoms can overlap with other infections, so discharge or itching alone cannot confirm trichomoniasis.

Take tinidazole exactly as prescribed and complete the prescribed course. Avoid alcohol during treatment and for the interval your prescriber advises afterward, because the combination can cause unpleasant reactions. Check before using it with other medicines or supplements.

Avoid sex until you and your sexual partner or partners have completed treatment and symptoms have settled, following clinical advice. Partners may need assessment and treatment even if they feel well. Retesting or review may be advised if symptoms return.

Contact your clinician for persistent discharge, itching, pelvic pain, painful urination or symptoms that return after treatment. Seek urgent help for facial swelling, breathing difficulty, faintness, severe rash or severe abdominal pain.

How was trichomoniasis confirmed, what exact tinidazole schedule should I follow, and when can I resume sex? Should my partner be treated, and do I need testing for other sexually transmitted infections?
