Tinidal is used for treating certain parasitic and bacterial infections. Tinidal is an antiprotozoal and antibiotic. It works by killing sensitive parasites and bacteria.
Use Tinidal as directed by your doctor.
- Take Tinidal 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 Tinidal. Talk with your doctor about how you should take cholestyramine with Tinidal.
- If more than one dose of Tinidal is required, continue using Tinidal 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 Tinidal, 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 Tinidal.

Important Tinidal Safety Information
- Tinidal may cause drowsiness or dizziness. These effects may be worse if you take it with alcohol or certain medicines. Use Tinidal 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 Tinidal and for 3 days after the last dose.
- Tinidal only works against bacteria and parasites; it does not treat viral infections (eg, the common cold).
- Be sure to use Tinidal 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.
- Tinidal 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 Tinidal. To prevent pregnancy, use an extra form of birth control (eg, condoms).

- Tinidal may interfere with certain lab tests. Be sure your doctor and lab personnel know you are taking Tinidal.
