Use of amitriptyline in the treatment of interstitial cystitis.

Author information

Department of Surgery, Hospital of the University of Pennsylvania, Philadelphia.


A total of 25 patients with interstitial cystitis who had failed standard therapy with hydrodistension of the bladder during anesthesia and intravesical dimethyl sulfoxide instillation underwent treatment with the tricyclic antidepressant amitriptyline. The initial dosage of 25 mg. before bed was increased gradually during a 3-week period to 75 mg. at bedtime. Of the patients 20 were able to tolerate the medication for a minimum of 3 weeks and could be evaluated for response. A significant improvement was noted in pain and daytime frequency. Of 9 patients 8 experienced relief of dyspareunia and 11 of 19 reported diminished urinary urgency. Eight patients have experienced virtual total remission of symptoms and have been on the drug for 4 to 28 months. It appears reasonable to consider the use of amitriptyline in patients with interstitial cystitis refractory to standard therapy.
