Product Description

Common use
Tinidazole is used for treating certain parasitic and bacterial infections. Tinidazole is an antiprotozoal and antibiotic. It works by killing sensitive parasites and bacteria.

Dosage and direction

Use Tinidazole as directed by your doctor.
Take Tinidazole by mouth with food.
If you have trouble swallowing the tablets, check with your doctor or pharmacist.
If you take cholestyramine, do not take it at the same time you take Tinidazole. Talk with your doctor about how you should take cholestyramine with Tinidazole.
If more than one dose of Tinidazole is required, continue using Tinidazole for the full course of treatment in order to clear up your infection completely, even if you feel better in a few days. Do not miss any dose.
If you miss a dose of Tinidazole, take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.
Ask your health care provider any questions you may have about how to use Tinidazole.

Important safety information:
Tinidazole may cause drowsiness or dizziness. These effects may be worse if you take it with alcohol or certain medicines. Use Tinidazole with caution. Do not drive or perform other possible unsafe tasks until you know how you react to it.
Avoid drinking alcohol or taking products that contain alcohol while taking Tinidazole and for 3 days after the last dose.
Tinidazole only works against bacteria and parasites; it does not treat viral infections (eg, the common cold).
Be sure to use Tinidazole for the full course of treatment. If you do not, the medicine may not clear up your infection completely. The bacteria or parasites could also become less sensitive to this or other medicines. This could make the infection harder to treat in the future.
Tinidazole may discolor or darken the urine. This is normal and not a cause for concern.
Hormonal birth control (eg, birth control pills) may not work as well while you are using Tinidazole. To prevent pregnancy, use an extra form of birth control (eg, condoms).
Tell your doctor or dentist that you take Tinidazole before you receive any medical or dental care, emergency care, or surgery.
Tinidazole may interfere with certain lab tests. Be sure your doctor and lab personnel know you are taking Tinidazole.
Lab tests, including blood cell counts, may be performed while you use Tinidazole. These tests may be used to monitor your condition or check for side effects. Be sure to keep all doctor and lab appointments.
Use Tinidazole with extreme caution in children younger 3 years; safety and effectiveness in these children have not been confirmed.
Pregnancy and breast-feeding: Tinidazole may cause harm to the fetus. Tinidazole should not be used during the first trimester of pregnancy. If you think you may be pregnant, contact your doctor. You will need to discuss the benefits and risks of using Tinidazole while you are pregnant. Tinidazole is found in breast milk. Do not breast-feed while taking Tinidazole and for 3 days after you have taken the last dose.
