Dopamine and Tranylcypromine Interaction

Drug interaction information between Dopamine and Tranylcypromine.

Dopamine and Tranylcypromine have a documented moderate interaction in FDA labeling.

FDA drug labeling documents a moderate-severity interaction between Dopamine and Tranylcypromine. Major interactions are generally avoided, moderate ones may need monitoring or a dose adjustment, and minor ones are usually low-risk. This page shows the documented mechanism and guidance. Label-documented interactions are not a complete safety review, so always confirm your own medications with a pharmacist or doctor. Educational information, not medical advice.

Drug A

Dopamine

Inotropic / Vasopressor

Drug B

Tranylcypromine

Monoamine Oxidase Inhibitor (MAOI)

How They Interact

Tranylcypromine prevents the body from breaking down dopamine, which can cause dopamine levels to become dangerously high. This can result in a life-threatening increase in blood pressure.

What To Do

Avoid this combination if possible, as it can be very dangerous. If dopamine must be used, your doctor will need to use a much lower dose and monitor your blood pressure constantly.

Frequently Asked Questions

Can I take Dopamine and Tranylcypromine together?

This is a moderate interaction. Avoid this combination if possible, as it can be very dangerous. If dopamine must be used, your doctor will need to use a much lower dose and monitor your blood pressure constantly.

How serious is the interaction between Dopamine and Tranylcypromine?

This interaction is classified as "moderate" severity by the FDA. Moderate interactions may worsen your condition or change how your medications work.

Why do Dopamine and Tranylcypromine interact?

Tranylcypromine prevents the body from breaking down dopamine, which can cause dopamine levels to become dangerously high. This can result in a life-threatening increase in blood pressure.

Understanding the Dopamine and Tranylcypromine Interaction

FDA-approved prescribing information for these two drugs flags their combination as a moderate-severity interaction. Dopamine belongs to the Inotropic / Vasopressor class and Tranylcypromine belongs to the Monoamine Oxidase Inhibitor (MAOI) class - two categories that can collide when co-prescribed. The mechanism described in FDA labeling is: Tranylcypromine prevents the body from breaking down dopamine, which can cause dopamine levels to become dangerously high. Severity tiers matter: major flags generally advise avoidance, moderate flags often require monitoring or dose adjustment, and minor flags may only call for awareness.

Context around a specific patient determines real-world impact. Dopamine has 28 total documented interactions on file in this dataset, and Tranylcypromine has 42. Each additional medication compounds the interaction surface, which is why pharmacists run full-profile checks rather than evaluating one pair at a time. FDA-derived guidance for this pair is: Avoid this combination if possible, as it can be very dangerous. Timing of doses, renal and hepatic function, age, and other concurrent prescriptions all shape whether a labeled interaction matters clinically.

An interaction flag is not a verdict. A large share of labeled interactions are managed routinely in clinical practice, the fix may be as simple as spacing doses or adding a monitoring test. Others require the prescriber to choose a different medication entirely. This page surfaces FDA-sourced labeling and openFDA data for educational purposes only; it is not medical advice and cannot account for your full clinical picture. Never start, stop, or adjust either Dopamine or Tranylcypromine based on a web page, speak with your prescriber or pharmacist before making any change.
