in my opinion a 17 month old child should not have any "over- the- counter" medications given to them without the approval of a doctor. consult your child's pediatrician before giving any medication especially the first time. because of the potential for allergic reactions in babies they are much more likely than adults to have serious adverse drug consequences. dosing is another important consideration. appropriate dosing according to age and weight is an art best left to the physician. likewise specific instructions on either alternating or combining different "over-the-counter" medications should come only at the discretion of a doctor. many of these products contain the same or similar ingredients. even though some time may have elapsed between the transition from one medication to the other being given some of the first medication type may still remain in the child's system. doctors study pharmacology and are experienced in knowing the half-life of drugs as they are exhausted in the body. giving your child prescription or over-the-counter medication. is serious business.
