Is it okay for someone to give their prescription medication to a minor child even if it is their child?
With rare exception, it is against the law for anyone to give medication to someone other than the individual for whom the prescription was written and the medication obtained. Giving another person a life-sustaining emergency "shared" dose of another's medication would most likely not be against the law. If for instance, the mother is a physician and diagnoses her child as needing X antibiotic immediately and gives the child X antibiotic from a clearly labeled bottle of X antibiotic, more likely than not it is not against the law.
I hope the circumstances would be a serious breach of common sense and posing a danger to the health, safety, and welfare of the minor child before someone would raise this issue against a parent. If the parent had knowledge of the use and side effects of the medication and decided, after MD hours or pharmacy hours, to give child 2 a dose of child 1's medicine for cough, I think it would take a low-life person to call the authorities or attempt to use such in a custody issue.
