Why is this medication prescribed?

Tacrine is used to treat the symptoms of Alzheimer's disease, but it does not cure the disease.

This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.

How should this medication be used?

Tacrine comes as a capsule to take by mouth. It usually is taken four times a day. Take tacrine on an empty stomach (1 hour before or 2 hours after meals). Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take tacrine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Continue to take tacrine even if you feel well. Do not stop taking tacrine without talking to your doctor, especially if you have taken large doses for a long time. Your doctor probably will decrease your dose gradually. This drug must be taken regularly for a few weeks before its full effect is felt.
