Tranylcypromine
Brand Name(s): Parnate®; also available genericallyTransamine sulphate
IMPORTANT WARNING:
A small number of children, teenagers, and young adults (up to 24 years of age) who took antidepressants ('mood elevators') such as tranylcypromine during clinical studies became suicidal (thinking about harming or killing oneself or planning or trying to do so). Children, teenagers, and young adults who take antidepressants to treat depression or other mental illnesses may be more likely to become suicidal than children, teenagers, and young adults who do not take antidepressants to treat these conditions. However, experts are not sure about how great this risk is and how much it should be considered in deciding whether a child or teenager should take an antidepressant. Children younger than 18 years of age should not normally take tranylcypromine, but in some cases, a doctor may decide that tranylcypromine is the best medication to treat a child's condition.
You should know that your mental health may change in unexpected ways when you take tranylcypromine or other antidepressants even if you are an adult over age 24. You may become suicidal, especially at the beginning of your treatment and any time that your dose is increased or decreased. You, your family, or your caregiver should call your doctor right away if you experience any of the following symptoms: new or worsening depression; thinking about harming or killing yourself, or planning or trying to do so; extreme worry; agitation; panic attacks; difficulty falling asleep or staying asleep; aggressive behavior; irritability; acting without thinking; severe restlessness; and frenzied abnormal excitement. Be sure that your family or caregiver knows which symptoms may be serious so they can call the doctor when you are unable to seek treatment on your own.
Your healthcare provider will want to see you often while you are taking tranylcypromine, especially at the beginning of your treatment. Be sure to keep all appointments for office visits with your doctor.
The doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin treatment with tranylcypromine. Read the information carefully and ask your doctor or pharmacist if you have any questions. You also can obtain the Medication Guide from the FDA website: https://www.fda.gov/Drugs/DrugSafety/ucm085729.htm.
No matter what your age, before you take an antidepressant, you, your parent, or your caregiver should talk to your doctor about the risks and benefits of treating your condition with an antidepressant or with other treatments. You should also talk about the risks and benefits of not treating your condition. You should know that having depression or another mental illness greatly increases the risk that you will become suicidal. This risk is higher if you or anyone in your family has or has ever had bipolar disorder (mood that changes from depressed to abnormally excited) or mania (frenzied, abnormally excited mood) or has thought about or attempted suicide. Talk to your doctor about your condition, symptoms, and personal and family medical history. You and your doctor will decide what type of treatment is right for you.

WHY is this medicine prescribed?
Tranylcypromine is used to treat depression in people who have not been helped by other medications. Tranylcypromine is in a class of medications called monoamine oxidase inhibitors (MAOIs). It works by increasing the amounts of certain natural substances that are needed to maintain mental balance.
HOW should this medicine be used?
Tranylcypromine comes as a tablet to take by mouth. It is usually taken twice a day. Take tranylcypromine at around the same times every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take tranylcypromine exactly as directed.
Tranylcypromine may be habit-forming. Do not take a larger dose, take it more often, or take it for a longer period of time than prescribed by your doctor. Call your doctor if you find that you want to take extra medication or you notice any other unusual changes in your behavior or mood.
Your doctor will probably start you on a low dose of tranylcypromine and gradually increase your dose, not more often than once every 1-3 weeks. After your symptoms improve, your doctor will probably gradually decrease your dose of tranylcypromine.
Tranylcypromine controls the symptoms of depression but does not cure the condition. It may take 3 weeks or longer for you to feel the full benefit of tranylcypromine. Continue to take tranylcypromine even if you feel well. Do not stop taking tranylcypromine without talking to your doctor. Your doctor will probably want to decrease your dose gradually.
Are there OTHER USES for this medicine?
This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.
What SPECIAL PRECAUTIONS should I follow?
Before taking tranylcypromine,
- tell your doctor and pharmacist if you are allergic to tranylcypromine or any other medications.
- some medications should not be taken with tranylcypromine. Other medications may cause dosing changes or extra monitoring when taken with tranylcypromine. Make sure you have discussed any medications you are currently taking or plan to take before starting tranylcypromine with your doctor and pharmacist. Before starting, stopping, or changing any medications while taking tranylcypromine, please get the advice of your doctor or pharmacist.
- you should know that tranylcypromine may remain in your body for several weeks after you stop taking the medication. During the first few weeks after your treatment ends, tell your doctor and pharmacist that you have recently stopped taking tranylcypromine before you start taking any new medications.
- the following nonprescription products may interact with tranylcypromine: dextromethorphan; tryptophan. Be sure to let your doctor and pharmacist know that you are taking these medications before you start taking tranylcypromine. Do not start any of these medications while taking tranylcypromine without discussing with your healthcare provider.
- tell your doctor if you have or have ever had high blood pressure; frequent or severe headaches; pheochromocytoma (a tumor on a small gland near the kidneys);a stroke or mini-stroke; or heart, blood vessel, or liver disease. Your doctor may tell you not to take tranylcypromine.
- tell your doctor if you use or have ever used street drugs or have overused prescription medications. Tell your doctor if you have or have ever had anxiety, agitation, diabetes, seizures, or kidney or thyroid disease.
- tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while taking tranylcypromine, call your doctor.
- if you are having surgery, including dental surgery, or any x-ray procedure, tell the doctor or dentist that you are taking tranylcypromine.
- you should know that this medication may make you drowsy. Do not drive a car or operate machinery until you know how this medication affects you.
- remember that alcohol can add to the drowsiness caused by this medication. Do not drink alcohol while you are taking tranylcypromine.
- you should know that tranylcypromine may cause dizziness, lightheadedness, and fainting when you get up too quickly from a lying position. This is more common when you first start taking tranylcypromine. To avoid this problem, get out of bed slowly, resting your feet on the floor for a few minutes before standing up.
What SPECIAL DIETARY instructions should I follow?
You may experience a serious reaction if you eat foods that are high in tyramine during your treatment with tranylcypromine. Tyramine is found in many foods, including meat, poultry, fish, or cheese that has been smoked, aged, improperly stored, or spoiled; certain fruits, vegetables, and beans; alcoholic beverages; and yeast products that have fermented. Your doctor or dietitian will tell you which foods you must avoid completely, and which foods you may eat in small amounts. You should also avoid foods and drinks that contain caffeine during your treatment with tranylcypromine. Follow these directions carefully. Ask your doctor or dietitian if you have any questions about what you may eat and drink during your treatment.
What should I do IF I FORGET to take a dose?
Take the missed dose as soon as you remember it. However, if it is almost time for your next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.

What should I know about STORAGE and DISPOSAL of this medication?
Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).
Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website (https://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location — one that is up and away and out of their sight and reach. https://www.upandaway.org
