Blackbox WarningTOP

OverviewTOP

This medicine is also used to treat vaginal infections caused by bacteria .
Tinidazole is available only with your doctor's prescription.
Proper UseTOP
If this medicine upsets your stomach, it may be taken with meals or a snack. If stomach upset (nausea, vomiting, stomach pain, or diarrhea) continues, check with your doctor.
To help clear up your infection completely, keep taking this medicine for the full time of treatment, even if you begin to feel better after a few days. If you stop taking this medicine too soon, your symptoms may return.
In some kinds of infections, this medicine works best when there is a constant amount in the blood. To help keep the amount constant, do not miss any doses. Also, it is best to take the doses at evenly spaced times, day and night. For example, if you are to take one dose a day, the doses should be spaced about 24 hours apart. If this interferes with your sleep or other daily activities, or if you need help in planning the best times to take your medicine, check with your health care professional.
Some types of infections are treated with one dose of tinidazole.
