Description
Ovex – 1 Threadworm Treatment Tablet
Ovex is a pharmacy medicine used to treat threadworm infections (also known as pinworms) in adults and children aged 2 years and over. It contains the active ingredient mebendazole, which effectively clears threadworm infections with a single tablet.
⸻
How It Works
Mebendazole works by blocking the threadworms’ ability to absorb glucose (sugar), which is their only source of energy. Without glucose, the worms are unable to survive and die within a few days, allowing your body to clear them naturally.
⸻
Directions for Use
Adults and children aged 2 years and over should take one tablet (100 mg mebendazole) as a single dose. The tablet can be chewed, swallowed whole, or crushed and mixed with food. Because threadworms spread easily between people, it is strongly recommended that all household members are treated at the same time, even if they have no symptoms. If re-infection occurs within 2 weeks, a second dose may be taken. Always read the patient information leaflet before use. If you are unsure about the correct dose, speak to your PillSorted pharmacist.

Interactions
Mebendazole may interact with certain medicines, including metronidazole and cimetidine, which can increase the level of mebendazole in the blood. There are no known significant food interactions with Ovex. Tell your PillSorted pharmacist or doctor about all medicines you are currently taking, including herbal remedies and supplements.
⸻
Pregnancy and Breastfeeding
Ovex should not be used during pregnancy, as mebendazole may not be safe for the developing baby. If you are breastfeeding, the use of Ovex is generally not recommended, as small amounts of mebendazole may pass into breast milk. Speak to your doctor or PillSorted pharmacist before use if you are pregnant, trying to conceive, or breastfeeding.

Alcohol
There is no known interaction between mebendazole and alcohol. However, as a general precaution, it is advisable to drink alcohol in moderation whilst being treated for any infection.
