Tricyclic antidepressants have been used to manage pain for several decades, and are superior treatments for some patients suffering from neuropathic pain. Unfortunately, older antidepressants have dose-limiting side effects that can lead to drug intolerance. The most common are anticholinergic side effects, although some patients experience sexual dysfunction. Cognitive impairment, sedation, and orthostatic hypotension also are relatively common. Taking an overdose of tricyclic antidepressants can be lethal in overdose. Several weeks of therapy may be required before antinociception occurs, but tricyclic antidepressants in optimal doses appear to be the most effective treatment for neuropathic pain; this is supported by systematic reviews comparing them with other agents. Newer medications such as atypical antidepressants and anticonvulsants may be overtaking older antidepressants, but they should not be overlooked as important options for the management of pain.
Antidepressants, particularly tricyclic antidepressants, have been a mainstay in the prophylactic therapy of migraine. The tricyclic antidepressants amitriptyline, nortriptyline, and doxepin have been the major agents for prophylactic treatment of migraine. These cause significant side effects in some patients. The high-affinity selective serotonin reuptake inhibitors and other newer antidepressants have been disappointing and much less effective in the treatment of migraine. In patients who are depressed with severe migraine, a tricyclic antidepressant may treat both conditions; however, the addition of a newer atypical antidepressant may be needed.
