My child is 4. can he talk cough medicine?

Some of them: The best thing to do is ask your child's doctor. Many of the over-the-counter cough meds have been shown to be ineffective in children, or cause side effects. When I do use one, I tend to use a simple antihistamine (Benadryl, Zyrtec) instead of a combination med. Honey (in warm water or tea) has also been found to be effective for cough- in children over 2 yrs old.

Robatussin: Most if not all of the combination cough medicines have been found ineffective in kids under 12. They have not been recommended for kids under 6 for a decade because of ER visits from overdoses. Robatussin is helpful in some. For most, good nutrition, hydration and rest will heal them well.
