What Is the Best Threadworm Treatment for Children?

 

Threadworms are one of the most common childhood infections in the UK. If your little one has been scratching around their bottom — especially at night — there's a good chance threadworms are the culprit. The good news? Treatment is straightforward. Threadworm treatment for children doesn't have to mean a battle over tablets. Ovex Suspension Family Pack in banana flavour offers a child-friendly liquid option that the whole household can use together, making it far easier to tackle the infection at its root.

Each 30ml bottle contains mebendazole 100mg/5ml as the active ingredient. It's an over-the-counter medicine available without a prescription, suitable for adults and children aged 2 years and over. At just £11.99, it's an accessible, clinician-recommended option for families dealing with a threadworm outbreak. If you're also looking after younger children or babies, browse our Baby and Toddler range for age-appropriate health products.

 

How Does Ovex Suspension Work Against Threadworms?

 

Mebendazole — the active ingredient in Ovex Suspension — is an anthelmintic medicine. It works by interfering with the threadworms' ability to absorb glucose, which is their primary energy source. Without glucose, the worms are unable to survive and die within a few days of treatment.

  • Mebendazole selectively targets the worm's glucose uptake mechanism
  • The worms are gradually immobilised and die
  • Dead worms are then passed naturally through the bowel
  • The medicine does not kill threadworm eggs — hygiene measures are essential alongside treatment

Because eggs can survive on surfaces for up to two weeks, it's important to wash bedding, towels, and nightwear on the day of treatment, and to encourage thorough handwashing — particularly after using the toilet and before meals.

 

Who Should Use Ovex Suspension Family Pack?

 

This suspension is designed for families where at least one member has been diagnosed with, or is suspected to have, a threadworm infection. Because threadworms spread so easily — through contaminated hands, bedding, and surfaces — treating the whole household at once is the most effective approach.

  • Children aged 2 years and over who have difficulty swallowing tablets
  • Adults who prefer a liquid formulation
  • Households where multiple members need simultaneous treatment
  • Anyone who has been in close contact with a confirmed threadworm case

It is not suitable for children under 2 years of age, or for use during pregnancy without medical advice. Always read the label before use.

 

How Does Ovex Suspension Compare to Ovex Tablets?

Formulation Oral suspension (liquid) Chewable tablet
Suitable for children Yes, aged 2 years and over Yes, aged 2 years and over
Flavour Banana Orange / unflavoured

Is Ovex Suspension Suitable for Long-Term or Repeated Use?

 

Ovex Suspension is intended for short-term use only. A single 5ml dose is taken, and if reinfection occurs, a second dose may be taken after two weeks. It is not designed for ongoing or preventative use. If threadworm infections keep recurring despite treatment and hygiene measures, speak to your GP — there may be an underlying reason why the infection keeps returning.

Store the suspension below 25°C and do not refrigerate. Keep the bottle tightly closed and out of reach of children. As with all medicines, check the expiry date before use. If you're managing other digestive health concerns alongside a threadworm infection, our IBS and Cramps collection may have products that support your gut health more broadly.

This product is a medicine. Speak to your doctor or pharmacist before using if you have an underlying medical condition or are taking other medicines.

What Is Ovex Suspension and What Is It Used For?

 

Ovex Suspension is a banana-flavoured oral liquid medicine used to treat threadworm infections (also known as pinworm infections, caused by Enterobius vermicularis). It contains mebendazole 100mg per 5ml as its active ingredient. Threadworms are tiny white worms that live in the gut and around the back passage. They are extremely common in the UK, particularly in school-age children, and spread easily through contact with contaminated surfaces, clothing, or bedding.

The NHS advises treating all household members at the same time, even if they don't have symptoms, to reduce the risk of reinfection. This family pack is designed with exactly that in mind — one bottle, enough for the whole household.

 

What Do You Need to Know Before Using Ovex Suspension?

 

Before giving this medicine to anyone in your household, check the following contraindications and warnings carefully:

  • Do not use in children under 2 years of age
  • Do not use during pregnancy, especially in the first trimester — speak to your GP or midwife first
  • Do not use if you are breastfeeding without first seeking medical advice
  • Do not use if the person has a known allergy to mebendazole or any other ingredient in the suspension
  • Use with caution in people with liver problems — seek medical advice first
  • Not licensed for use in children under 2 years; alternative advice from a GP should be sought for this age group

Regarding drug interactions, the following medicines may interact with mebendazole:

  • Metronidazole — concurrent use may increase the risk of skin reactions (Stevens-Johnson syndrome has been reported in rare cases)
  • Cimetidine — may increase plasma levels of mebendazole
  • Anticonvulsants such as carbamazepine or phenytoin — may reduce the effectiveness of mebendazole

Always tell your pharmacist about any medicines you or your child are currently taking before starting treatment.

 

How Should You Use Ovex Suspension?

 

  1. Shake the bottle well before use
  2. Measure 5ml (one teaspoon) using the measuring spoon or oral syringe provided
  3. Give the suspension by mouth — it can be swallowed directly or mixed with a small amount of food
  4. Treat all household members aged 2 years and over at the same time
  5. If reinfection occurs or symptoms persist after two weeks, a second dose may be taken
  6. Maintain strict hygiene measures for at least six weeks: wash hands thoroughly, keep nails short, wash bedding and nightwear on the day of treatment
Indication Age Group Dose Frequency

Threadworm infection Adults 5ml (100mg mebendazole) Single dose; repeat after 2 weeks if needed

What Are the Possible Side Effects of Ovex Suspension?

 

Most people tolerate Ovex Suspension well. Side effects are uncommon, particularly with the short-term, single-dose regimen used for threadworm treatment. However, as with all medicines, some people may experience unwanted effects.

Common side effects (may affect up to 1 in 10 people):

  • Mild abdominal pain or stomach cramps
  • Diarrhoea
  • Flatulence

Less common side effects (may affect up to 1 in 100 people):

  • Nausea or vomiting
  • Dizziness
  • Headache
  • Skin rash or itching
  • Raised liver enzymes (with prolonged use at higher doses — not typically relevant for single-dose threadworm treatment)

Seek immediate medical attention if you notice signs of a serious allergic reaction, such as swelling of the face, lips, or throat, difficulty breathing, or a severe skin rash. These reactions are rare but require urgent care. If you're managing any digestive discomfort after treatment, our Diarrhoea range may offer supportive relief.

 

How Should You Store Ovex Suspension?

 

  • Store below 25°C
  • Do not refrigerate or freeze
  • Keep the bottle tightly closed when not in use
  • Keep out of the sight and reach of children
  • Do not use after the expiry date printed on the bottle
  • Do not dispose of medicines via wastewater or household waste — return unused medicine to your pharmacist for safe disposal

Frequently Asked Questions

Where can I buy Ovex Suspension online in the UK?

You can buy Ovex Banana Suspension 30ml directly from Cured Pharmacy, a GPhC-registered UK online pharmacy. It is available without a prescription as an over-the-counter Pharmacy (P) medicine. Simply add it to your basket and complete a short online consultation at checkout.

How does Ovex Suspension work in the body?

Ovex Suspension contains mebendazole, which blocks the threadworms' ability to absorb glucose — their only energy source. Without glucose, the worms become immobilised and die within a few days. The dead worms are then passed naturally through the bowel without any discomfort.

How do I use Ovex Suspension step by step?

Shake the bottle well, then measure 5ml using the spoon or oral syringe provided. Give it by mouth — it can be swallowed directly or mixed with a small amount of food. Treat all household members aged 2 years and over at the same time, and maintain strict hygiene measures for at least six weeks afterwards.

What is the correct dose of Ovex Suspension for a child?

For children aged 2 years and over, the dose is one 5ml spoonful (equivalent to 100mg mebendazole) taken as a single dose. If symptoms return or reinfection occurs, a second dose may be taken two weeks after the first. Do not give to children under 2 years of age.

When is the best time to take Ovex Suspension?

There is no specific time of day required — Ovex Suspension can be taken at any time, with or without food. Many families find it easiest to give the dose in the morning so they can monitor for any mild side effects during the day. The key is that all household members take their dose on the same day.

Can the whole family take Ovex Suspension at the same time?

Yes — in fact, the NHS recommends treating all household members simultaneously, even if they have no symptoms. Threadworms spread very easily, and treating only the person with visible symptoms often leads to reinfection. The 30ml family pack is sized to cover multiple household members in one go.

How long does Ovex Suspension take to work?

Mebendazole typically kills threadworms within a few days of taking the dose. However, because the medicine does not kill threadworm eggs, itching around the bottom may continue for up to two weeks while eggs are still present. Strict hygiene measures — including handwashing and washing bedding — are essential throughout this period.

What are the side effects of Ovex Suspension and how do I manage them?

Side effects are uncommon with a single dose but may include mild stomach pain, diarrhoea, or nausea. These usually resolve on their own without any treatment. If you experience a severe skin rash, facial swelling, or difficulty breathing, seek emergency medical attention immediately as these may indicate a rare allergic reaction.

Is Ovex Suspension safe during pregnancy?

Ovex Suspension is not recommended during pregnancy, particularly during the first trimester, as mebendazole may carry a risk to the developing baby. If you are pregnant and think you have threadworms, speak to your GP or midwife before using any treatment. They can advise on the safest approach for your situation.

Who is eligible to use Ovex Suspension?

Ovex Suspension is suitable for adults and children aged 2 years and over who have a threadworm infection or have been in close contact with someone who does. It is not suitable for children under 2 years, pregnant women (without medical advice), or people with a known allergy to mebendazole. If you have liver problems, consult your GP before use.

What happens if I miss a dose of Ovex Suspension?

Because Ovex Suspension is taken as a single dose, a "missed dose" situation is unlikely. However, if you forget to treat all household members on the same day, give the missed dose as soon as you remember. If two weeks have passed and symptoms persist, a second dose can be taken at that point.

What are the alternatives to Ovex Suspension for threadworms?

The main alternative is Ovex chewable tablets, which contain the same active ingredient (mebendazole 100mg) and work identically — the choice between them is largely down to preference or ease of administration. Another option is Pripsen sachets, which contain piperazine and sennosides, though this is less commonly used. For children who can swallow tablets, our Baby and Toddler section may have additional suitable options.

How long do you need to use Ovex Suspension for?

Ovex Suspension is a single-dose treatment — you take one 5ml dose and that's it, unless reinfection occurs. If symptoms return after two weeks, a second dose may be taken. It is not intended for long-term or preventative use. Persistent or recurring infections should be discussed with a GP.

What is the difference between Ovex Suspension and Ovex tablets?

Both products contain mebendazole 100mg and work in exactly the same way. The suspension is a banana-flavoured liquid, making it easier for young children or anyone who struggles to swallow tablets. The tablets are chewable and may be more convenient for older children and adults. Clinically, there is no difference in effectiveness between the two formulations.

What are the latest guidelines on treating threadworms in children?

Current NHS guidance recommends mebendazole as the first-line threadworm treatment for children aged 2 years and over, combined with strict hygiene measures to prevent reinfection. The guidance emphasises treating all household members simultaneously and maintaining hygiene practices — such as regular handwashing and washing bedding — for at least six weeks. You can find further digestive health support in our IBS and Cramps collection if needed.

How Should You Use Ovex Suspension?

Using Ovex Suspension correctly gives you the best chance of clearing a threadworm infection quickly and preventing it from coming back. The process is simple, but it's important to follow each step carefully — especially when treating children.

Hygiene measures are just as important as the medicine itself. Threadworm eggs can survive on surfaces for up to two weeks, so maintaining good hand hygiene and keeping the home clean is essential throughout the treatment period.

What Is the Correct Dose of Ovex Suspension?

The dose is the same for adults and children aged 2 years and over — one 5ml spoonful, taken as a single dose. There is no weight-based dosing adjustment required for this indication. If symptoms return or reinfection is suspected, a second dose may be taken two weeks after the first.

When Is the Best Time to Use Ovex Suspension?

There is no specific time of day required for taking Ovex Suspension — it can be given at any time, with or without food. Many families find it practical to give the dose in the morning so that any mild side effects, such as stomach discomfort, can be monitored during waking hours. The most important timing consideration is that all household members take their dose on the same day to prevent reinfection.

It's also worth timing the treatment alongside a thorough household clean — washing bedding, towels, and nightwear on the same day as the dose helps remove eggs from the environment and reduces the risk of the infection cycling back through the family.

How Long Can You Use Ovex Suspension For?

Ovex Suspension is a short-term, single-dose treatment. You take one dose, and if reinfection occurs, a second dose after two weeks. It is not intended for ongoing, preventative, or long-term use. If threadworm infections keep recurring despite correct treatment and hygiene measures, this should be discussed with your GP, as there may be an underlying reason for persistent reinfection.

Hygiene measures — including regular handwashing, keeping nails short, and avoiding scratching around the bottom — should be maintained for at least six weeks after treatment to ensure all eggs have been eliminated from the environment.

Do not exceed the recommended dose. If in doubt, speak to your pharmacist.

What Are the Most Common Side Effects of Ovex Suspension?

Most people who take Ovex Suspension experience no side effects at all, particularly with the single-dose regimen used for threadworm treatment. When side effects do occur, they are usually mild and short-lived, affecting the digestive system.

  • Mild abdominal pain or stomach cramps
  • Diarrhoea
  • Flatulence (wind)

These effects typically resolve on their own within a day or two and do not usually require any additional treatment. Staying well hydrated can help if diarrhoea occurs.

What Are the Less Common Side Effects of Ovex Suspension?

Less commonly, some people may experience the following side effects. These are not typical with a single dose but are worth being aware of, particularly if you or your child have any underlying health conditions.

  • Nausea or vomiting
  • Headache
  • Dizziness
  • Skin rash or itching (urticaria)
  • Raised liver enzymes — more relevant with prolonged high-dose use, not typically seen with single-dose threadworm treatment

If any of these effects are troublesome or do not resolve, contact your pharmacist or GP for advice.

What Are the Serious Side Effects of Ovex Suspension?

Serious side effects from mebendazole at the doses used for threadworm treatment are rare. However, you should be aware of the signs of a serious allergic reaction (anaphylaxis), which requires immediate emergency medical attention.

  • Swelling of the face, lips, tongue, or throat
  • Difficulty breathing or swallowing
  • Severe skin rash, blistering, or peeling
  • Rapid heartbeat or feeling faint

If you or your child experience any of these symptoms after taking Ovex Suspension, call 999 or go to your nearest A&E immediately. Do not wait to see if symptoms improve on their own.

What Should You Do If You Experience Side Effects?

For mild side effects such as stomach discomfort or loose stools, no specific treatment is usually needed — rest and keeping hydrated is generally sufficient. If side effects are severe, persistent, or worrying, stop using the medicine and contact your pharmacist or GP. You can also report suspected side effects directly to the MHRA via the Yellow Card scheme at yellowcard.mhra.gov.uk.

Never take a second dose sooner than two weeks after the first, even if symptoms persist. If you are concerned that the treatment has not worked, speak to your pharmacist before repeating the dose.

Can Ovex Suspension Interact With Other Medicines?

Mebendazole can interact with certain other medicines. The most clinically significant interactions to be aware of include metronidazole (an antibiotic), which when used alongside mebendazole has been associated in rare cases with serious skin reactions. Cimetidine (used for indigestion) may increase the amount of mebendazole absorbed into the bloodstream. Anticonvulsant medicines such as carbamazepine or phenytoin may reduce the effectiveness of mebendazole.

Always tell your pharmacist about all medicines, supplements, and herbal remedies you or your child are currently taking before starting Ovex Suspension. This includes prescription medicines, over-the-counter products, and vitamins.

If you are concerned about any side effects, contact your pharmacist or GP immediately.
