Side effects

Been on Amitriptyline for 1 month and was started on 10 mgs and now on 20mgs and since they upt it to 20mgs my headaches have come back or is this a side effect of this medication.  I am on this due to having IIH.

Hello kav. Headache can be a side effect but not very common as far as I know. Sorry but what is IIH?

Idopathic Intercrainial Hypertension. Thank you.

I have had headaches before with amitriptyline but they usually settle down once you get used to it
