We all need to report these problems to the FDA. I filled out my report in about 5 minutes. There is also a number for Merck, I couldn't find an e-mail address. To report an adverse experience with a specific Merck product, please call the Merck National Service Center at 800-444-2080. Don't you wish that someone would have spoken up before our kids had to experience these side effects? Let's spare some other kids, fill out the form, it's worth your time.
