Yes, amitriptyline is prescribed for PCS head aches. I am very confused about the dosages mentioned on NT. The research on using amitriptyline for PCS suggests much smaller doses that many have been prescribed. Ten mgs is the suggested dosage. Even 25 mgs is quite an increase. I have read where some are taking 100 mgs per day.

Does anybody have any idea why these doctors are prescribing so much?
