The interval between indomethacin administration and clinical response may be clinically relevant in the assessment of chronic paroxysmal hemicrania continua and other unilateral headache disorders with they can be confounded. Eight patients with chronic paroxysmal hemicrania (6 women and 2 men) and 12 patients with hemicrania continua (8 women and 4 men) were entered into the study. The patients were given 50 mg of indomethacin intramuscularly (IM) on day 1 and some of them 100 mg IM on day 2 in an open fashion. The usual attack pattern was reestablished prior to the second test. The mean interval between attacks before the two injections (51 ± 18 minutes) in chronic paroxysmal hemicrania was significantly shorter than the mean after each of the two indomethacin injections (50 mg = 493 ± 251 minutes; 100 mg = 668 ± 211 minutes; P
