G Amitriptyline Amitriptyline Hydrochloride Riluzole
ModerateAmitriptyline may slow down how quickly your body clears Riluzole. This is because it affects CYP 1A2, one of the liver's enzymes that breaks Riluzole down. If the liver clears Riluzole more slowly, the medicine can stay in your body for longer. The leaflet says this is only a possibility, not something that will definitely happen. If you take both medicines, tell your doctor so they can keep an eye on you.
These medicines are often taken together with some care. Your doctor may change a dose, space them apart or check on you more often. Make sure your doctor and pharmacist know you take both.
