Which drug would you choose for treating pinworm in adults?

Mebendazole is the preferred drug for treating pinworm infections, also known as Enterobiasis, in adults. This medication is a type of anthelmintic that works by inhibiting the microtubule formation in the parasitic worms, leading to their immobilization and eventual death. It specifically targets pinworms effectively and is well-tolerated.

Other options, such as Metronidazole and Tinidazole, are primarily used for treating protozoal infections and certain bacterial infections, rather than for helminth, or worm, infections. Levofloxacin, an antibiotic used mainly for bacterial infections, does not have effectiveness against parasitic worm infestations.

Therefore, in the context of treating pinworms, Mebendazole is the most appropriate choice, as it specifically addresses the causative agent of the infection.
