What is Vermox?
Vermox (mebendazole) is an anthelmintic or anti-worm medication. It prevents newly hatched insect larvae (worms) from growing or multiplying in your body.
Vermox is used to treat infections caused by worms such as whipworm, pinworm, roundworm, and hookworm. It is also used to treat infections caused by more than one of these worms at the same time.
Vermox may also be used for purposes not listed in this medication guide.
Follow all directions on your medicine label and package. Tell each of your healthcare providers about all your medical conditions, allergies, and all medicines you use.

How should I take Vermox?
Take Vermox exactly as directed by your doctor. Follow all directions on your prescription label. Do not take this medicine in larger or smaller amounts or for longer than recommended.
A Vermox tablet may be swallowed, chewed, or crushed and mixed with food.
Use this medicine for the full prescribed length of time. Your symptoms may improve before the infection is completely cleared. Skipping doses may also increase your risk of further infection that is resistant to antibiotics. Vermox will not treat a viral infection such as the flu or a common cold.
You may need to take this medicine for 1 to 3 days, depending on the condition you are treating. However, it could take as long as 3 weeks before the infection is completely cleared.
Wash your hands and fingernails often, especially before you eat or after using the bathroom.
If the infection does not clear up within 3 weeks, you may need a second treatment.
To prevent reinfection, follow your doctor's instructions about disinfecting your home and carefully washing all clothing, linens, and towels. Your family members or other people in your household may also need to be treated with Vermox or other medicines. Pinworm infections can easily spread from one person to another.
You cannot cure a worm infection by fasting (starving), using laxatives, or forcing yourself to vomit. For best results, take this medicine as directed.
Store Vermox at room temperature away from moisture and heat.
