The amount to give will be written on the medicine label. The dose of Lamivudine is based on your child’s weight, so it is important that your child is weighed every time they come to clinic. Usually Lamivudine is given TWICE a day.

As it is very important that the amount of Lamivudine in the blood remains steady, try to give the doses as close to every 12 hours as you can. You may need an oral syringe or measuring spoon to give the liquid correctly. You can get these from the paediatric pharmacy.


You can give Lamivudine before, with or after food. Sometimes eating just before a dose can help to stop your child feeling sick with the medicine.

If you miss a dose:

If you forget to give a dose, give it as soon as you remember - as long as it is less than six hours after the usual dose time. Missing doses regularly can reduce the amount of Lamivudine in the blood - allowing the virus to become resistant to it.

If your child vomits a large amount soon after giving a dose of Lamivudine, give a replacement dose as soon as your child feels able to take it, as long as it is within two hours of the usual dose time.
