Peritonsillar Abscess in Children: Care Instructions

Child's open mouth and throat, showing tongue, tonsils, uvula, and peritonsillar abscess near a tonsil.

Your Care Instructions

A peritonsillar abscess is a collection of pus that forms in tissues around one or both of the tonsils. It can occur as a result of strep throat or another infection. An abscess can cause severe pain and make it very hard to swallow.

Your child will need antibiotics. In some cases, the abscess will have been drained through a needle or small incision.

Your child may have had a sedative to help them relax. Your child may be unsteady after having sedation. It takes time (sometimes a few hours) for the medicine's effects to wear off. Common side effects of sedation include nausea, vomiting, and feeling sleepy or cranky.

Follow-up care is a key part of your child's treatment and safety. Be sure to make and go to all appointments, and call your doctor if your child is having problems. It's also a good idea to know your child's test results and keep a list of the medicines your child takes.

How can you care for your child at home?

If the doctor prescribed antibiotics for your child, give them as directed. Do not stop using them just because your child feels better. Your child needs to take the full course of antibiotics.
Be safe with medicines. Give pain medicines exactly as directed.
- If the doctor gave your child a prescription medicine for pain, give it as prescribed.
- If your child is not taking a prescription pain medicine, ask your doctor if your child can take an over-the-counter medicine.
- Do not give aspirin to anyone younger than 20. It has been linked to Reye syndrome, a serious illness.
Make sure your child gets lots of rest.
Follow your doctor's instructions if the abscess was drained through a needle or small incision.
While your child's throat is very sore, use liquid nourishment such as soup or high-protein drinks.
