Drug information provided by: Micromedex

It is very important that your doctor check your progress at regular visits to make sure that this medicine is working properly. Blood tests may be needed to check for unwanted effects.

Telithromycin should not be taken with cisapride (Propulsid®), colchicine, or pimozide (Orap®). Doing so may increase the risk of serious side effects.

If your symptoms do not improve within a few days, or if they become worse, check with your doctor.

Stop taking telithromycin and contact your doctor right away if you have symptoms of liver disease. These symptoms include tiredness, body aches, loss of appetite, nausea, yellow skin and eyes, dark urine, light-colored stools, itchy skin, or severe stomach pains. Severe liver problems and liver failure have been reported, and in some cases, liver injury developed quickly and after only a few doses.

This medicine may cause fainting, blurred vision, or other vision problems. If any of these occur, do not drive, use machines, or do anything else that could be dangerous if you are not able to see well or if you feel lightheaded. If these side effects occur and they bother you, check with your doctor.

This medicine may cause diarrhea, and in some cases it can be severe. It may occur up to 2 months or more after you stop taking this medicine. Do not take any medicine to treat diarrhea without first checking with your doctor. If you have any questions or if mild diarrhea continues or gets worse, check with your doctor.

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
