A double-blind study was undertaken by volunteers, 20 of whom had chlorpromazine (Largactil), 10 mg. r.ds., and 30 of whom had mefenamic acid (Ponstan), 250 mg. 4 times a day, for a period of 60 days. In both groups there were no significant untoward effects, and it appears that both drugs can be safely given to patients with porphyria variegata.
