Ovex (Mebendazole)

Mebendazole, the active ingredient in Ovex, is an anthelmintic presented as a tablet for oral use. It treats intestinal worm infections such as ascariasis, hookworm disease, and trichuriasis in both children and adults.

GNH USA supplies Ovex as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals and pharmacies worldwide.

Mebendazole is used to treat helminthic infections by targeting the parasite’s metabolic pathways. It is indicated for: - Ascariasis: eliminates the adult Ascaris lumbricoides worms, reducing intestinal burden. - Hookworm disease: eradicates hookworm species, relieving anemia and gastrointestinal symptoms. - Trichuriasis: removes Trichuris trichiura infections, improving stool consistency and abdominal discomfort.

Mebendazole is generally well tolerated, but adverse reactions can occur.

Common Side Effects: - Abdominal pain: mild to moderate discomfort in the stomach area. - Nausea: feeling of queasiness often without vomiting. - Diarrhea: loose, watery stools that may be transient. - Headache: mild tension‑type headache. - Rash: mild skin erythema or itching.

Serious or Rare Side Effects: - Hepatotoxicity: elevated liver enzymes indicating liver stress. - Agranulocytosis: marked reduction in white blood cells, increasing infection risk. - Severe allergic reaction: hives, swelling, or difficulty breathing. - Stevens‑Johnson syndrome: rare severe skin blistering. - Blood dyscrasias: abnormal blood counts requiring monitoring.

When using Mebendazole, consider the following precautions: - Pregnancy: avoid use during the first trimester unless benefits outweigh risks. - Breastfeeding: consult a healthcare professional before use. - Liver function: assess hepatic status in patients with known liver disease. - Blood counts: monitor complete blood count in prolonged therapy. - Drug interactions: review concomitant medications for potential interactions. - Store below 25°C: keep in the original packaging, protect from moisture and direct sunlight.

Mebendazole may interact with several medicines; monitoring is advised.

Major Interactions (Avoid): - Cytochrome P450 3A4 inhibitors: may increase systemic exposure. - Cimetidine: can raise plasma levels of mebendazole.

Moderate Interactions (Monitor Closely): - Antifungal azoles (e.g., ketoconazole): may modestly increase mebendazole concentrations. - Anticoagulants (e.g., warfarin): potential alteration of INR. - Antiepileptic drugs (e.g., carbamazepine): may affect metabolism. - Oral contraceptives: possible reduction in efficacy. - Vitamin A supplements: theoretical risk of additive toxicity.
