Tranylcypromine (Parnate) is taken by mouth and used to treat depression. It's not a first choice medication because it has many drug and food interactions. It can also put you at risk for dangerously high blood pressure. Tranylcypromine (Parnate) is usually used after other medications haven't worked well. It's available as a lower-cost generic.
Depression when other medications haven't worked
Tranylcypromine (Parnate) is a monoamine oxidase inhibitor (MAOI). It blocks a protein in your brain that breaks down certain chemicals, such as norepinephrine, dopamine, and serotonin. This allows these chemicals to stay in your brain longer, which can help improve your mood.

MAOI medications like tranylcypromine (Parnate) can cause your blood pressure to become too high, which in some cases can be fatal. Certain foods like processed meat (salami, pepperoni), cheese, yogurt, or any food or drink that has been aged, pickled, or fermented can raise the risk of high blood pressure and should be avoided. There are also medications, like over-the-counter (OTC) cough and cold medications, weight loss supplements, and allergy medications that should also be avoided while taking tranylcypromine (Parnate). Always talk to a provider or pharmacist before starting any new medications to make sure it doesn't interact with your current medications.

This problem typically goes away after you stop tranylcypromine (Parnate).
