Summary

Transdermal selegiline provides systemic MAO inhibition at antidepressant doses. Combined with modafinil, which has stimulant and mild sympathomimetic properties, there is a risk of elevated blood pressure and, rarely, hypertensive reactions.

What this interaction means in plain words

Modafinil and Selegiline transdermal can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.

Evidence level: Low

Why it happens

MAO inhibition combined with modafinil's dopaminergic and noradrenergic effects may produce additive pressor responses.

What to do

Avoid unless benefit clearly outweighs risk; if combined, monitor blood pressure closely, especially after dose changes.

What to ask your pharmacist

  • Does the benefit of taking both outweigh the risk in my case?
  • Do I need any blood test, ECG or other check while on both?
  • What early warning signs should I watch for, and what should I do if they appear?
