Question 3

How does Phenelzine work?

Accepted Answer

Mechanism of Action

Phenelzine works by inhibiting the activity of monoamine oxidase, a natural enzyme in the body. This enzyme is responsible for breaking down neurotransmitters, which are chemical messengers that transmit signals between nerve cells in the brain.

By blocking this enzyme, phenelzine increases the concentration of several key neurotransmitters, including:

Serotonin: Often associated with mood regulation and feelings of well-being.

Norepinephrine: Involved in alertness, energy, and the stress response.

Dopamine: Linked to pleasure, motivation, and motor function.

Higher levels of these chemicals can improve brain cell communication and help stabilize mood. Because it targets these pathways differently than more modern antidepressants, phenelzine is often used for individuals whose symptoms have not improved with other treatments.

Do not change your dose or stop taking this medication without talking to your healthcare provider first. Stopping the medication suddenly can lead to unwanted side effects. It is often necessary to continue taking the medication even after you begin to feel better.

Strictly follow any dietary guidelines provided by your doctor while taking this medication, as certain foods and drinks can cause dangerous interactions.

Question 9

Is Phenelzine safe during pregnancy and breastfeeding?

Accepted Answer

There is limited research on the effects of phenelzine during human pregnancy. Animal studies have indicated potential risks, but well-controlled studies in humans are not available. As a monoamine oxidase inhibitor (MAOI), phenelzine can cause severe interactions with certain foods and medications, leading to dangerously high blood pressure that may pose risks to both the pregnant person and the fetus.

If you are pregnant or planning to become pregnant, it is important to discuss your treatment options with your healthcare provider. They will help determine if the benefits of the medication justify the potential risks to the pregnancy.

It is unknown whether phenelzine passes into breast milk or if it could harm a nursing infant. Because many medications are excreted in breast milk, caution is recommended. You should consult with a healthcare professional to discuss the safety of breastfeeding while taking phenelzine and to evaluate the potential risks to the infant.
