Frequently asked questions
Why must I avoid alcohol?
Alcohol with tinidazole can cause flushing, vomiting and a racing heart.

For trichomoniasis, sexual partners usually need treatment too to prevent reinfection.
How is it different from metronidazole?
They are similar, but tinidazole lasts longer in the body, so courses are often shorter.
