Can I take Amitriptyline and Modifinil together?

Why this happens

Modafinil can slow down the liver enzymes (specifically CYP2C19) that are responsible for breaking down amitriptyline. Because the body cannot clear the amitriptyline as quickly as usual, the drug builds up in your system. Additionally, both drugs can affect heart rate and brain activity, which may lead to additive effects.

What you should do

You should consult your doctor before taking these two medicines together. Your doctor may need to adjust your dose of amitriptyline or monitor you more closely for side effects. Seek medical help immediately if you experience a very fast or irregular heartbeat, severe dizziness, or fainting.
