Name of drug


Why is it important for my child to take this medicine?

This medicine may be recommended if your child’s nephrotic syndrome keeps coming back and they need frequent treatment with steroids. Levamisole stimulates the immune system and should reduce the need for steroid treatment.

What is levamisole available as?

  • Tablets: usually 50 mg, but other strengths are available

When should I give levamisole?

Levamisole is usually given every other day (Monday, Wednesday, Friday, Sunday, Tuesday, Thursday, Saturday, Monday, etc.).

It is given once a day. This is usually in the morning but you can choose another time if it helps you to give it regularly. Try to give it at about the same time of day each time.

How much should I give?

Your doctor will work out the amount of levamisole (the dose) that is right for your child. The dose will be shown on the medicine label.

It is important that you follow your doctor’s instructions about how much to give.

How should I give levamisole?

TabletsTablets should be swallowed with a glass of water, milk or juice. Your child should not chew the tablet.

You can crush the tablet and mix it with a small amount of soft food such as yogurt, honey or jam. Make sure your child swallows it straight away, without chewing.

You can also crush the tablet and mix it with water (it will not dissolve but will make a cloudy suspension). Draw up the right volume into an oral syringe to give to your child you can get these from your pharmacist. Your doctor or pharmacist will tell you how much water to use, and how much of the mixture to give your child. Throw the rest of the mixture away.

When should the medicine start working?

Levamisole should prevent or reduce relapses of nephrotic syndrome and the need for treatment with steroids. Your doctor will probably suggest that your child takes levamisole regularly for 6 months to see whether it helps them to have fewer relapses.

What if my child is sick (vomits)?

  • If your child is sick less than 30 minutes after having a dose of levamisole, give them the same dose again.
  • If your child is sick more than 30 minutes after having a dose of levamisole, you do not need to give them another dose. Wait until the next normal dose.

What if I forget to give it?

If you remember on the day that the dose is due, give it as soon as you remember, then continue to give levamisole every other day in your usual pattern at the usual time.

If you remember after the day the dose was due, give a dose as soon as you remember. Then continue to give your usual dose every other day from that point.

What if I give too much?

If you accidently give your child too much levamisole, you are unlikely to do harm. Your child may get an upset stomach, dizziness or a headache.

If you worried that you may have given your child too much levamisole, or your child seems unwell, contact your doctor or NHS Direct (0845 4647 in England and Wales; 08454 24 24 24 in Scotland). Have the packet with you if you telephone for advice.

Are there any possible side-effects?

We use medicines to make our children better, but sometimes they have other effects that we don’t want (side-effects).

Side-effects you must do something about

Very rarely, levamisole can causes seizures (convulsions or fits). If your child has a seizure, telephone for an ambulance. Do not restrain your child, but try to make sure that they cannot hurt themselves (e.g. put a cushion under their head and move obstacles away).

Other side-effects you need to know about
  • Your child may have side-effects when they first start taking levamisole. These usually wear off after a week or so. If they continue to be a problem after 2 weeks, contact your doctor for advice.
  • Your child may feel sick or be sick (vomit). It may help if your child takes the medicine with some food or a small glass of milk.
  • Your child may get diarrhoea, headache, dizziness, a rash or muscle pains.
  • Levamisole sometimes affects blood cells. Your doctor will test your child’s blood regularly to check for this.

Can other medicines be given at the same time as levamisole?

  • You can give your child medicines that contain paracetamol, unless your doctor has told you not to.
  • Levamisole can be safely taken with ibuprofen, although this medicine is not recommended for children with kidney disease. Contact your doctor for advice if you feel that your child needs ibuprofen.
  • Levamisole should not be taken with some common drugs that you get on prescription. Tell your doctor and pharmacist about any medicines your child is taking before starting levamisole.
  • Check with your doctor or pharmacist before giving any other medicines to your child. This includes herbal or complementary medicines.

Is there anything else I need to know about this medicine?

This medicine may be prescribed as tablets of different strengths. When you get a new prescription, check what strength tablets you have been given, and how many you should give your child.

  • Levamisole is also used to treat round worm and hookworm infections. Usually only a single dose is used for these infections.
  • Try to give medicines at about the same times each day, to help you remember.
  • Only give levamisole to your child. Never give it to anyone else, even if their condition appears to be the same, as this could do harm.

If you think someone else may have taken the medicine by accident, contact your doctor for advice.

  • Make sure that you always have enough medicine. Order a new prescription at least 2 weeks before you will run out.
  • Make sure that the medicine you have at home has not reached the ‘best before’ or ‘use by’ date on the packaging. Give old medicines to your pharmacist to dispose of.

Where should I keep this medicine?

  • Keep the medicines in a cupboard, away from heat and direct sunlight. It does not need to be kept in the fridge.
  • Make sure that children cannot see or reach the medicine.
  • Keep the medicine in the container it came in.
