If the cause of the tonsillitis is bacteria such as strep, antibiotics are given to cure the infection. The antibiotics may be given once as a shot, or taken for 10 days by mouth.

If antibiotic pills are used, they must be taken for the entire amount of time prescribed by the doctor. DO NOT stop taking them just because the discomfort stops, or the infection may not be cured.

Rest to allow the body to heal. Fluids, especially warm (not hot), bland fluids or very cold fluids may soothe the throat. Gargle with warm salt water or suck on lozenges (containing benzocaine or similar ingredients) to reduce pain.

Over-the-counter medications, such as acetaminophen (Tylenol) or ibuprofen may be used 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).

Tonsillitis symptoms usually improve 2 or 3 days after treatment starts. The infection usually is cured after treatment is completed, but some people may need more than one course of antibiotics.

Complications of untreated strep tonsillitis may be severe. Children with tonsillitis related to strep throat or pharyngitis should generally be kept home from school or day care until they have been on antibiotics for 24 hours. This helps reduce the spread of illness.
