Is it illegal to let a friend borrow Advil (or other OTC remedies)?

[AbbySthrnAccent]

TeenSthrnAccent has braces, the bottoms were just added yesterday. Our dentist told him to take Advil, so I gave him some of those little travel packets with two pills for his sports bag. He's starts his day with swim pratice, then teaches swimming lessons until about 10am, then goes to another pool to guard. Late in the day a fellow guard asked him if he had something for a headache. His reply was, I have some packets of Advil my mom gave me." A parent over heard and told my son he could be sued for dispensing medication. Is this true?

It's not like the young lady was in pain and he said, "Here take two and call me in the morning." She approached him.

What say ye teemings?
