Getting the mebendazole dose right depends entirely on which worm you are treating. Pinworm needs a single 100mg dose repeated at 2 weeks — not a 3-day course. Roundworm and hookworm need twice-daily 100mg for 3 days or a single 500mg dose. This guide covers every dose, children's dosing, 100mg vs 500mg comparison, and the most common dosing mistakes.

Mebendazole is the leading deworming medicine for pinworm, roundworm, hookworm and whipworm infections in adults and children.
