Protriptyline and Zolpidem 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.
Why it happens
Additive pharmacodynamic CNS depression via GABA-A agonism and tricyclic antihistaminic and anticholinergic effects.
