allergy. We contacted the Irish Medicines Board 2 (Dublin, Ireland), who had no reports of anaphylaxis in association with Roaccutane Ò and no information on underlying peanut allergy in reported allergic-type reactions to this medication. The Medicines and Healthcare Products Regulatory Agency 3 (London, U.K.) reported three cases of anaphylaxis in association with Roaccutane Ò . A history of peanut allergy may require the use of an alternative agent as in this case. We report the use of acitretin as an effective alternative to isotretinoin in the treatment of acne and also alert dermatologists to inform patients that Roaccutane Ò contains peanut extract.
