Diethylcarbamazine
[3] Common side effects include itching, facial swelling, headaches, and feeling tired.[citation needed] In India and China, diethylcarbamazine has been added to salt to combat lymphatic filariasis.[medical citation needed] Diethylcarbamazine is contraindicated in patients who may have onchocerciasis, due to the risk of the Mazzotti reaction.This makes the microfilariae more susceptible to innate immune attack, but does not kill the parasites outright.[14] Brand names include Hetrazan, Carbilazine, Caricide, Cypip, Ethodryl, Notézine, Spatonin, Filaribits, Banocide Forte, and Eofil.
