Why, yes. For instance, when I gave my child Symbiocort (an asthma medication) I said to him (this is an exact transcript, since I record all converations with Legalsea Junior for legal reasons):
"Legalsea Junior, some side effects you may experience include hives; difficulty breathing; swelling of your face, lips, tongue, or throat; worsening asthma symptoms; chest pain, fast or pounding heartbeats, tremors, nervousness; wheezing, throat irritation, choking, or other breathing problems; signs of infection such as fever, chills, sore throat, flu symptoms, easy bruising or bleeding, unusual weakness; blurred vision, eye pain, or seeing halos around lights; white patches or sores in your mouth or throat; or dangerously high blood pressure (Junior, this may involve severe headache, blurred vision, buzzing in your ears, anxiety, confusion, chest pain, shortness of breath, uneven heartbeats, and even seizure activity).
Furthermore, Junior, you may also notice headache; back pain; nausea, vomiting, diarrhea, upset stomach; back pain, muscle cramps; sore throat, stuffy nose; joint or muscle pain; or even changes in your voice."
Actually, I would tell the child to tell me if they notice anything strange about themselves, without actually telling them what.
