The oral dosage for moxidectin in adults and children 12 and up is 8 mg in a single dose. [53] Moxidectin has been found to more strongly suppress the O. volvulus microfilariae for longer than ivermectin treatments, with peak clearance of microfilariae in the skin at one month after treatment. After six months post-treatment, many individuals ...

Upon infesting a human host, the adult female burrows into the stratum corneum (outermost layer of skin), where she deposits two or three eggs per day. These oval eggs are 0.1–0.15 mm (0.0039–0.0059 in) long and hatch as ...

Ivermectin is an antiparasitic drug. [7] After its discovery in 1975, [8] its first uses were in veterinary medicine to prevent and treat heartworm and acariasis. [9] Approved for human use in 1987, [10] it is used to treat infestations including head lice, scabies, river blindness (onchocerciasis), strongyloidiasis, trichuriasis, ascariasis and lymphatic filariasis.
For treatment of scabies: Adults and children older than 2 months are instructed to apply the cream to the entire body from head to the soles of the feet. Wash off the cream after 8–14 hours. In general, one treatment is curative. [18] A single application of permethrin is more effective than a single oral dose of ivermectin for scabies.
[10] Benzyl benzoate can be a skin irritant when used as a topical scabicide. [7] Overdose can result in blistering and hives or a rash can occur as an allergic reaction. [12] [13] As an excipient in some testosterone-replacement injectable medications, benzyl benzoate has been reported as a cause of anaphylaxis in a case in Australia. [14]
