## What is Zentel 400 mg

Zentel 400 mg Tablet is an anthelmintic medicine used to treat intestinal worm infections caused by pinworms, roundworms, whipworms, and hookworms. It contains 400 mg of Albendazole, an FDA-approved deworming salt from the benzimidazole drug class. It is manufactured by GlaxoSmithKline Pharmaceuticals Ltd. as a chewable tablet at WHO-GMP-certified manufacturing units.

Albendazole prevents worms from absorbing glucose, which is the energy they need to survive. As their energy stores decline, the worms die and are cleared through the stool. It works on the worms but not on their eggs. This is why a repeat dose may be advised after 2 to 3 weeks if the infection is not fully cleared.

For common intestinal worm infections in adults and children aged 2 years or older, a single Zentel 400 mg dose is advised. For threadworm, pork or beef tapeworm, and other sensitive worm infections, you may need to take 400 mg once daily for 3 consecutive days.

The Zentel 400 mg tablet should be chewed before swallowing. It can be taken without fasting, purging, or laxatives. If you or your child vomits soon after taking the medicine, ask your doctor whether the dose should be repeated. Since worm infections can spread easily among family members, everyone should get treatment together.

Common Albendazole side effects include abdominal pain, nausea, vomiting, Diarrhea, headache, and dizziness. These are usually mild and short-lived. Seek urgent medical help if signs of allergy, skin blistering, breathing difficulty, unusual bleeding, or severe rash develop.

Avoid Zentel 400 if you have an allergy to Albendazole or are pregnant. Medical supervision is advised for people with liver disease, in children under 2 years of age, and while breastfeeding. Avoid combining with medicines, such as Cimetidine, Praziquantel, Dexamethasone, Ritonavir, Phenytoin, Carbamazepine, and Phenobarbital, as they can alter Albendazole levels in the body.

Store Zentel 400 mg tablets in a dry place below 30°C, away from light.
