Peritonsillar Abscess

You or your child has a collection of pus (abscess) around the tonsils. This abscess can cause severe sore throat, pain with swallowing, fever, drooling, and trouble opening the mouth.

The abscess is treated with antibiotics. These may be started using an I.V. (intravenous line), then continued by mouth. In most cases, the pus will also be drained. If you have a history of many abscesses or episodes of tonsillitis, your tonsils may be removed.

Home care

  • If your doctor prescribed antibiotics, take them as directed. Do not stop taking them just because you feel better. You need to take the full course of antibiotics.

  • Take pain medicines as directed. Don't take any over-the-counter medicine for this condition without talking with your doctor, especially the first time.

  • To help ease pain, children older than 6 years and adults can gargle with warm saltwater 4 times a day for the first 2 days. Dissolve 1/2 teaspoon (2.5 ml) of salt in 1 glass of warm water. Gargle with the solution then spit it out. (Check that children don't swallow the saltwater.)

  • Cool liquids and soft foods may make eating easier for the first few days.

  • Don’t smoke, and stay away from secondhand smoke.

Follow-up care

Follow up with a doctor or as advised within 1 to 2 days.
