Joe was riding his skateboard at the skatepark when he fell and thought he sprained his ankle. He went to the local urgent care and was treated for his sprained ankle. The doctor he saw gave him a prescription pain medicine to help him as he heals, since he was in some pain.The medication states take 1 pill every 4 - 6 hours. Can take up to 2 pills, if needed.

Joe takes 1 pill and then an hour later takes another since he still was feeling pain.

Is this proper medication use or misuse?
