What Nardil is used for
The name of your medicine is Nardil. It contains the active ingredient phenelzine.
Nardil is used to treat major depression. There are many different types of medicines used to treat depression. Nardil belongs to a group of medicines called Monoamine Oxidase Inhibitors (MAOIs).
Depression is longer lasting and/or more severe than the "low moods" everyone has from time to time due to the stress of everyday life. It is thought to be caused by a chemical imbalance in parts of the brain. This imbalance affects your whole body and can cause emotional and physical symptoms such as feeling low in spirit, loss of interest in activities, being unable to enjoy life, poor appetite or overeating, disturbed sleep, often waking up early, loss of sex drive, lack of energy and feeling guilty over nothing.
Antidepressants are thought to work by acting on brain chemicals called amines, which are involved in controlling mood.
Your doctor, however, may prescribe Nardil for another purpose.
Ask your doctor if you have any questions about why Nardil has been prescribed for you.
This medicine is available only with a doctor's prescription.

While you are using Nardil
Things you must do
Before you have any surgery or emergency treatment, tell your doctor or dentist that you are taking Nardil or have used it within the last ten days. Carry an alert card or wear an SOS bracelet which tells the doctor you are taking Nardil.
These are helpful if you are in an accident and cannot talk.
If you are about to be started on any new medicines, tell your doctor or pharmacist that you are taking Nardil.
Do not take any other medicines, whether they require a prescription or not, without first telling your doctor.
Tell your doctor if you become pregnant while taking Nardil.
Talk to your doctor about what foods you should avoid. Nardil reacts with alcohol and certain foods and drinks that contain the chemical Tyramine.
The following foods and beverages may react with Nardil:
Meat and fish:
- Pickled herring
- Dry sausage (including salami, pep
- Broad bean pods
- Cheese (cottage cheese and cream cheese are allowed)

The above list of foods and beverages should be avoided while taking Nardil, and for two weeks after discontinuing Nardil therapy.

If you have a reaction after consuming one of these foods or beverages, call your doctor or go to Accident and Emergency at your nearest hospital.
If you took a small amount of one of these foods one time, without a reaction, it does not mean you will not have a reaction the next time.
Tell your doctor if, for any reason, you have not taken your medicine exactly as prescribed. Otherwise, your doctor may think that your currently prescribed dose is not working as expected and change your treatment unnecessarily.
Be sure to keep all of your appointments with your doctor so that your progress can be checked. Your doctor may want to take some blood tests and check your heart and blood pressure from time to time. This helps prevent unwanted side effects.
If you are taking Nardil, you should report the occurrence of headaches or other unusual symptoms.
Things you must not do
Do not stop taking Nardil or lower the dose, without first checking with your doctor.
Do not let yourself run out of medicine over the weekend or on holidays.

Do not give this medicine to somebody else, even if their symptoms seem similar to yours or if they have the same condition as you.
Do not use Nardil to treat other complaints unless your doctor says to.
Things to be careful of
Watch carefully for signs that your depression or anxiety is getting worse, especially in the first one to two months of treatment or when there is a change in dose.
