Antidepressant medicines, which are usually used to treat depression, can be effective in preventing chronic tension headaches. Antidepressants have some pain-relieving properties and may reduce how often headaches occur and how long they last.
Amitriptyline can also be used as an anticholinergic drug in the treatment of early-stage Parkinson's disease if depression also needs to be treated. Amitriptyline is the most widely researched agent for prevention of frequent tension headaches.
