Tell your GP or pharmacist before taking amitriptyline if you:
- are on any other medicine
- have taken any other medicines in the last 14 days
If you are going to have a general or local anaesthetic as part of surgery or dental treatment, tell your doctor or dentist that you are taking amitriptyline.
