Unfortunately, there's no cure for the common cold. Antibiotics may be used to combat bacterial infections, but they have no effect on viruses. The best you can do is to make your child comfortable. Make sure your child gets extra rest and drinks lots of fluids.
Your pediatrician may want to see your child or ask you to watch him or her closely and report back if there is not daily improvement or a full recovery after one week.
To Relieve a Stuffy Nose:
Nose drops or spray
Use saltwater (saline) nose drops (1 to 2 drops in each nostril) or spray (1 to 2 sprays in each nostril). For infants, use a rubber suction bulb to suck out the extra drops or spray. When using the suction bulb, remember to squeeze the bulb part of the syringe first, gently stick the rubber tip into one nostril, and then slowly release the bulb. This slight amount of suction will draw the clogged mucus out of the nose and should allow her to breathe and suck at the same time once again. You'll find that this technique works best when your baby is under 6 months of age. As your baby gets older, he or she will fight the bulb, making it difficult to suction the mucus, but the saline drops will still be effective.
To Relieve a Cough:
Do not give honey to babies under one year—it is not safe.
For children ages 1 to 5 years: Try half a teaspoon of honey.
For children ages 6 to 11: Try one teaspoon of honey.
For children 12 or older: Try two teaspoons of honey.
If honey is given at bedtime, make sure your child's teeth are brushed afterward.
Cough drops or lozenges
To Relieve a Fever:
Acetaminophen or Ibuprofen
If your child has a fever and is very uncomfortable, give her single-ingredient acetaminophen or ibuprofen. Always call your pediatrician before giving medicine to a child under 2 years of age, and call right away if your child is under three months of age and has a fever.
For children over the age of 2 years, check the label to see how much medicine to give. If you know your child's weight, use that. If you do not know your child's weight, go by age for the dose amount. See Fever and Pain Medicine: How Much to Give Your Child for more information.
Ibuprofen is approved for use in children 6 months of age and older; however, it should never be given to children who are dehydrated or who are vomiting repeatedly.
Do not give your child aspirin, which has been linked with Reye syndrome, a rare but very serious illness that affects the liver and the brain.
Ask the doctor for the right medicine and dose in millileters (mL) for your child's age and size. Always measure each dose using a device (syringe, dosing cup, or distinctly marked measuring spoon) that is marked in milliliters. Watch the video The Healthy Children Show: Giving Liquid Medicine Safely for more information.
Prevention & Treatment:
Children 6 months or older should get a flu vaccine each year. Children who are older than 6 months but younger than 2 years should get a flu shot.
Children younger than 6 months are too young to get a flu vaccines. In order to protect them, make sure the people around them get a flu vaccine.
Over-the-counter cough & cold medicines:
Over-the-counter (OTC) cough and cold medicines should not be given to infants and children under 4 years of age because of the risk of life-threatening side effects. Several studies show that cold and cough products don't work in children younger than 6 years and can have potentially serious side effects.
Many cold medicines already have acetaminophen (Tylenol or generic) in them. If you give one of these medicines along with acetaminophen or (Tylenol or generic), your child will get a double dose.
If antibiotics are prescribed:
Make sure children take them exactly as directed, even if they feel better. If antibiotic treatment stops too soon, the infection may get worse or spread in the body. Call the doctor if your child is not getting better with treatment.
If the antibiotic is a liquid, ask your child's doctor for the right dosage in millileters (mL) for your child's age and size. Always measure each dose using a device (syringe, cup, or spoon) that is marked in milliliters.
