Can you give my 14 year old daughter a naproxen tab 500mg for muscle sprain?

Naproxen is not recommended for children under the age of 16, so it is not appropriate to give your 14-year-old daughter this medication.

Muscle sprains in children are typically mild and can be treated with rest, ice, compression, and elevation (RICE). If the pain is severe, your daughter may need to see a doctor for further evaluation and treatment.
