Mebendazole over the counter is a widely used antiparasitic medication that helps eliminate various intestinal worm infections, including pinworms, roundworms, hookworms, and whipworms. It works by preventing the worms from absorbing essential nutrients, causing them to die and be expelled naturally through the stool. This medication is commonly available in tablet and chewable forms, making it suitable for both adults and children. The typical treatment duration varies depending on the type of infection — it can range from a single dose to a few days of therapy. Mebendazole is generally safe but may cause mild side effects such as stomach pain, diarrhea, or headache in some cases. For best results, it’s important to follow the doctor’s prescribed dosage and maintain good hygiene practices, like washing hands regularly and cleaning household items, to prevent reinfection. Mebendazole should be taken with or after food for better absorption.
