Patients are divided into two treatment groups, the first receiving AZT for 5 doses a day, and the second receiving AZT for 3 doses per day. A placebo group is divided into two to match the two treatment groups. Study patients are stratified according to whether they have (a) 10 or fewer cutaneous lesions without oral lesions or (b) more extensive cutaneous lesions or oral lesions. Patients are seen on an outpatient basis weekly for the first 2 months, every other week for the next 2 months, and monthly thereafter.
