What are the causes of Tonsillitis?

The tonsils are lymph nodes in the back of the mouth and top of the throat. They help to filter out bacteria and other germs to prevent infection in the body.

A bacterial or viral infection can cause tonsillitis. Strep throat is a common cause.

What are the current treatments for Tonsillitis?

Swollen tonsils that are not painful or do not cause other problems do not need to be treated. Your provider may not give you antibiotics. You may be asked to come back for a checkup later.

If tests show you do have strep, your provider will give you antibiotics. It is important to finish all of your antibiotics as directed, even if you feel better. If you do not take them all, the infection can return.

The following tips may help your throat feel better:

  • Drink cold liquids or suck on fruit-flavored frozen bars.
  • Drink fluids, and mostly warm (not hot), bland fluids.
  • Gargle with warm salt water.
  • Suck on lozenges (containing benzocaine or similar ingredients) to reduce pain (these should not be used in young children because of the choking risk).
  • Take over-the-counter (OTC) medicines, such as acetaminophen (Tylenol) or ibuprofen to reduce pain and fever. DO NOT give a child aspirin. Aspirin has been linked to Reye syndrome.

Some people who have repeated infections may need surgery to remove the tonsils (tonsillectomy).

What is the outlook (prognosis) for Tonsillitis?

Tonsillitis symptoms due to strep will often get better within 2 or 3 days after you start the antibiotics.

Children with strep throat should be kept home from school or day care until they have been on antibiotics for 24 hours. This helps reduce the spread of illness.

What are the possible complications of Tonsillitis?

Complications from strep throat may be severe. They may include:

  • Abscess in the area around the tonsils
  • Kidney disease caused by strep
  • Rheumatic fever and other heart problems
When should I contact a medical professional for Tonsillitis?

  • Pus in the back of the throat
  • Red rash that feels rough, and increased redness in the skin folds
  • Severe problems swallowing or breathing
