Colds and sore throats: Antibiotics won't always make your child feel better

Most infections are caused by a virus or bacteria. Antibiotics can only kill bacteria; they won't stop a virus.

Viruses cause the common cold and can make your throat feel sore. A sore throat also can be caused by Group A Streptococcus bacteria. Strep throat can be stopped by antibiotic medicine.

If antibiotics are used too much, the bacteria they're supposed to kill becomes resistant; the medicine will no longer work, and your child's sickness may get worse. That is why we try to make sure antibiotics are used only for bacterial infections.

What to expect at your next clinic visit

If you bring your child to an Allina Medical Clinic location because of a sore throat or cold-like symptoms, your child will need to have a rapid strep test or throat culture before receiving any prescription medicine. These tests check for bacteria.

If Group A Streptococcus bacteria shows up, your child has strep throat and will receive a prescription for antibiotics.

If the doctor says your child has an upper respiratory infection – the common cold – do not expect antibiotics. To help your child feel better, you may be advised to do the following:

• Make sure your child gets lots of rest.
• Prevent the spread of germs by washing your hands often.
• Use over-the-counter medicine, such as children's cough drops or acetaminophen, to relieve coughing, aches or fever.
• Call the clinic if your child's symptoms do no get better in seven days or if they get worse.
