When I was about 2 years old, I scraped my knee, and my mom went to the drugstore and picked up something to soothe the sore. When she put it on, it burned and hurt terribly, they had given her a ringworm medication in a similar box. I remember this 54 years later! It is very good to ask questions and read labels each time you get a refill, and especially if they are "in a hurry"! That's when the trouble often begins! Ken B
