Ovex Single Tablet is a medication designed to combat specific parasitic infections. The active ingredient in Ovex is mebendazole, which belongs to a class of drugs known as anthelmintics. This medication is primarily used to treat infestations of threadworms, which are common parasites that can affect both children and adults.

Threadworms, also known as pinworms, are small, white, thread-like worms that infest the intestines and can cause itching around the anus. Ovex works by paralyzing the threadworms, preventing them from absorbing essential nutrients, and ultimately leading to their expulsion from the body through bowel movements.
