tranylcypromine

Tranylcypromine is an antidepressant (monoamine oxidase inhibitor). This medication treats depression by restoring the balance of certain natural substances (neurotransmitters) in the brain. Tranylcypromine can improve your mood and feelings of well-being. Usually, this medication is used in persons who have not responded to treatment with other drugs.

Read the Medication Guide available from your pharmacist before you start using tranylcypromine and each time you get a refill. If you have any questions, consult your doctor or pharmacist.

Take this medication by mouth, usually in divided doses or as directed by your doctor. This medication may be taken with or without food. Dosage is based on your medical condition and response to therapy and usually will not be more than 60 milligrams per day.

To reduce your risk of side effects, your doctor may start you at a low dose and gradually increase your dose. Once your condition improves and you are better for a while, your doctor may work with you to reduce your regular dose. Follow your doctor's instructions carefully. Do not take more or less medication or take it more frequently than prescribed. Your condition will not improve any faster and your risk of side effects will increase.

Use this medication regularly in order to get the most benefit from it. To help you remember, use it at the same time(s) each day. It may take several weeks for the full benefits of this medication to be noticed. Do not stop taking this medication without consulting your doctor.

If you suddenly stop using this medication, you may have withdrawal symptoms (such as restlessness, confusion, hallucinations, headache, weakness, and diarrhea). To help prevent withdrawal, your doctor may lower your dose slowly. Withdrawal is more likely if you have used tranylcypromine for a long time or in high doses. Tell your doctor or pharmacist right away if you have withdrawal.

Inform your doctor if your condition persists or worsens.

Dizziness, drowsiness, tiredness, weakness, problems sleeping, constipation, and dry mouth may occur. If any of these effects persist or worsen, notify your doctor or pharmacist promptly.

To reduce the risk of dizziness and lightheadedness, get up slowly when rising from a sitting or lying position.

Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

This medication may increase serotonin and rarely cause a very serious condition called serotonin syndrome/toxicity. The risk increases if you are also taking other drugs that increase serotonin, so tell your doctor or pharmacist of all the drugs you take (see Drug Interactions section). Get medical help right away if you develop some of the following symptoms: fast heartbeat, hallucinations, loss of coordination, severe dizziness, severe nausea/vomiting/diarrhea, twitching muscles, unexplained fever, unusual agitation/restlessness.
