###Human: How good is Albenza for a raccoon roundworm exposure? ###Assistant: Hello. Albendazole 400 mg single star dose is enough for prophylactic deworming. 10 days course is not required. Usually, it is very safe and is well tolerated. A rare side effect is a seizure, that can happen if the worm is already lying dormant in your CNS. I generally prefer a three-day course of Mebendazole 100 mg twice daily as it does not enter CNS and so there are no changes of seizures. I hope it helps. If you have any further queries, please ask me.
