Bacteria cause sinus infections. Your child may have a sinus infection when there is:
Give your child the medicine ordered by your doctor. This medicine will kill the germs that cause the infection.
Put several drops of warm water or saline nose drops or spray in your child's nose. You can get saline nose drops at the drug store. You can use a suction bulb to gently suction out mucus from your child's nose. Suction mucus at least 4 times a day or any time your child cannot breathe through the nose. If your child is old enough, he can blow his nose instead of using a suction bulb.
If your child's sinuses are still blocked, use decongestant nose drops or sprays. Do not use such nose drops with children under age 12 unless your doctor tells you to do so.
Have your child use the nose drops for the first 2 or 3 days. Do not use these drops or sprays for more than 5 days. When you use these drops longer than 5 days, it can cause more problems.
Give your child acetaminophen (Tylenol) or ibuprofen (Advil) for fever over 102°F (39°C) or to stop pain. No aspirin.
If your child also has hay fever, give him allergy medicine.
Make sure your child drinks a lot. This helps thin the mucus.
