Vermox suspension, which is banana flavoured, contains an ingredient called Merbendazole which is highly effective against threadworms.

The presence of tiny white threads around the anal region is a sign of threadworm infestation. Common symptoms are itching around the anus or the vagina, restless sleep, grinding of teeth and irritability. If a family member has threadworms then each member should be treated. Before treating for threadworm, evidence of infestation should be present. Vermox may be used for treatment as it is also formulated to kill whipworm, roundworm and hookworm as well as threadworm.
