Allow blisters to dry out naturally. The blisters should not be deliberately burst because the fluid inside them is infectious.
It’s possible to make your child feel more comfortable by treating the symptoms:
- Paracetamol can ease pain and fever, but avoid aspirin. You can ask your doctor or pharmacist for advice on the right product and dose for your child.
- Give your child plenty to drink – sips of water or oral rehydration fluid can stop them becoming dehydrated. Ice blocks or jelly can soothe a sore mouth.
- Give your child soft foods. Avoid tangy or acidic food that could sting a sore mouth.
- Encourage your child to rest. Keep them home from day care or school until their blisters dry up.
If the symptoms are severe, please see a doctor.

- persistent fever (38°C or above for 72 hours or more)
- abnormal movements / jerking movements

If any of these signs are present, your child should see a doctor urgently even if they have been checked earlier in the illness.
