Question: how long does it take for emverm to kill pinworms?
Answer: After the initial dose of mebendazole, it beings to work quickly, within a few days at most. As mebendazole immobilizes and causes the death of infectious worms, you may begin to notice them in the stool. However, as mebendazole does not kill eggs, you may not be symptom free for one to three weeks.
