Summary

Doravirine is a CYP3A4 substrate, and armodafinil weakly induces CYP3A4. Reduced doravirine concentrations could compromise virologic suppression and promote resistance.

What this interaction means in plain words

Armodafinil and Doravirine can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.

Armodafinil belongs to Central Nervous System; Doravirine belongs to Anti Virals.

Evidence level: Low

Why it happens

Armodafinil induces CYP3A4, accelerating doravirine metabolism.

What to do

Monitor HIV viral load, or choose an alternative wakefulness agent. Strong inducers are contraindicated with doravirine, but armodafinil is weaker.
