In a double-blind controlled clinical trial comparing the safety and efficacy of oral diethylcarbamazine citrate (DEC) with topical DEC for the treatment of onchocerciasis twenty men with moderate skin-snip microfilarial counts received daily therapy for 1 week, then weekly therapy for the rest of 6 months. The number of microfilariae per skin snip dropped quickly to 2% of initial levels and remained at low levels in those receiving oral DEC, and to 20% of initial levels in patients treated with DEC lotion. Side-effects in both groups included lymphadenopathy, fever, pruritus, rash, proteinuria, and chorioretinitis; they were commoner with topical DEC.
