Overview
NOTE: After selecting this product, you will need to complete a short assessment, so we can make sure this medication is suitable for you.
Ovex Tablets Family Pack - Worm Treatment in UK
The Ovex Tablets family pack contains four single-dose tablets for treating threadworms. Threadworms are small, white, thread-like worms that live in your gut and can be seen in your poo. While not dangerous, they commonly cause itching and irritation around your bottom, especially at night.
Mebendazole tablets work by stopping the worms from absorbing the sugars they need to survive. A single dose of Ovex kills threadworms, but it doesn't kill their eggs, which can lead to re-infection and spread to others. To help prevent this, we strongly recommend that all members of your household – not suggested for pregnant or breastfeeding women and children under two – take these tablets and be treated at the same time.
Dosage and How to Take Ovex (mebendazole)
How to take ovex tablet
You can chew the tablet or swallow it whole with water, juice, or milk. Food is optional. If you’re using the liquid version, use the measuring spoon that comes with it. Don’t use a kitchen spoon—it won’t be accurate.
If you forget a dose
- If you take it twice a day and forget a dose, take it as soon as you remember within 4 hours.
- If it’s been more than 4 hours, skip the missed dose. Just take your next dose at the usual time.
- Don’t take 2 doses at once.
- If you take too much
Accidentally taking an extra dose probably won’t harm you, but you might feel:
- Stomach pain
- Nausea or vomiting
- Diarrhoea
Unless you feel seriously unwell, you likely won't need emergency help. However, if you're not sure or your symptoms are severe, please talk to your doctor or pharmacist for guidance.
What are the Symptoms of Threadworms?
The majority of the time, people are unaware of threadworms because of their slight symptoms. A common symptom is severe itching around the anus (or, in females, the vagina). especially at night, when female threadworms might annoy you with their egg-laying.
Some people have reported seeing threadworms in their stools or on their linens and bed clothes at night. These appear to be one-centimetre-long white cotton threads.
Severe infections with threadworms can lead to:
- Reduced weight
- Rapid reduction in weight
- Struggles with falling or staying asleep
- Bedwetting
In extremely rare circumstances, threadworms may find their way into the liver or urinary tract from outside the intestines.
Threadworms can be observed outside the vagina or womb in extremely uncommon instances in females, including adult women and girls.

Directions
Indications for Ovex:
- Ovex is primarily used to treat threadworm (pinworm) infections of the gut in adults and children over 2 years old.
- For young children who cannot swallow tablets, Ovex Suspension may be considered, but it should be used under medical supervision.
- It's important that all household members (except pregnant or breastfeeding women and children under 2) are treated simultaneously to prevent reinfection.
Dosage
Ovex Dosage for Threadworms
For threadworms (pinworms), take one Ovex tablet as soon as you notice symptoms or are told you have them.
You can take it at any time of day, with or without food.
Since threadworms spread easily, everyone in your household should take a dose at the same time to help stop them from coming back.
Your doctor or pharmacist might suggest a second dose after 2 weeks. That’s because Ovex kills the worms but not the eggs, and the extra dose helps get rid of any new worms that might have hatched.
Warnings
Ovex Warnings:
- Not suitable for pregnant or breastfeeding women.
- Not recommended for children under 2 years old.
- Consult your doctor or pharmacist if you’ve had side effects from any medication, including Ovex.
FAQ
What is Ovex?
Ovex is a brand name for a medication that is used to treat threadworms, which are small, white parasitic worms that live in the intestines.
It is mostly used to treat intestinal infections, such as threadworms (sometimes called pinworms) and other uncommon worm illnesses, such as whipworm, roundworm, and hookworm.
Who can use Ovex?
It is available for purchase from pharmacies for both adults and children two years of age and up. For kids six months and older, it's also accessible with a prescription.
In what forms is Ovex available?
Ovex comes in two forms: tablets and a suspension. Tablets are typically preferred for older children and adults, while suspension may be more suitable for younger children who may have difficulty swallowing tablets.
What is the active ingredient in Ovex and how does it work?
It contains the active ingredient mebendazole, which belongs to a group of medicines called anthelmintics. These medicines work by killing worms in the gut.
Is Ovex available over-the-counter?
Ovex is available over-the-counter in many countries, but it is always best to talk to your doctor or pharmacist before taking any new medication. This is especially important if you are pregnant, breastfeeding, or have any other medical conditions.
How long after taking Ovex should threadworms disappear?
While Ovex kills the worms, it may take a few days for them to die and be eliminated. You might still see them after treatment.
My child is really itchy in their sleep, what can I do to prevent this?
Threadworms lay eggs around the anus at night, causing itching. Keeping the area clean and wearing tight-fitting underwear at night can help.
At what age can a child take Ovex?
Ovex is generally not recommended for children under 2 years old. Always consult a doctor before treating young children.
Can my child still go to school if they're infected?
Yes, but good hygiene practices are crucial to prevent spreading the infection. Talk to your doctor for advice.
Can pinworms go away without treatment?
Pinworms usually do not go away without treatment. The infection continues as long as the adult worms remain in the intestine. Here, they continue to reproduce and lay eggs, making the infection even worse.
Without intervention, intestinal worms will continue to cause discomfort and spread to other family members. Therefore, it is necessary to use appropriate medications and follow strict hygiene practices to eliminate worms and prevent further transmission.
How quickly can pinworms be treated?
Threadworms can be treated using medications that have mebendazole. A good example is Ovex which is available here at Ashcroft Pharmacy.
Ovex begins to work immediately after administration. These drugs work by inhibiting the worms' ability to absorb the sugars necessary for their survival.
As a result, the worms die and are expelled from the body through feces.
Most people feel relief from itching and other symptoms within a few days of starting treatment. It is common practice to administer a second dose of the medication after two weeks to ensure that the newly hatched worms are killed, effectively eliminating the infection.
Can you see threadworms in your stool?
Yes, pinworms usually appear in the stool of infected people. These parasites appear as small white thread-like worms, usually about a centimeter long. Detecting pinworms in stool can help confirm the presence of an infection and speed up treatment.

About Worm infections
Worm infections occur when parasitic worms, like roundworms, tapeworms, or flukes, enter the body. This can happen through things like eating contaminated food, drinking dirty water, or walking barefoot on contaminated soil.
Once inside, these worms can cause various symptoms, such as stomach pain, diarrhea, and fatigue, depending on the type of worm and the severity of the infection.
Preventing worm infections involves simple practices like washing hands before eating, drinking clean water, and avoiding contact with contaminated soil.
In areas where worm infections are common, periodic deworming treatments may be necessary. If someone gets infected, treatment typically involves taking medication that kills and expels the worms from the body.
Severe infections with threadworms can lead to:
- Reduced weight
- Rapid reduction in weight
- Struggles with falling or staying asleep
- Bedwetting
In extremely rare circumstances, threadworms may find their way into the liver or urinary tract from outside the intestines.
Threadworms can be observed outside the vagina or womb in extremely uncommon instances in females, including adult women and girls.
