:confused: I found a pill in my sisters pocket and I wanted to know what its is.. It's blue and white and it has MYLAN 4455 inprinted it.

Try this site:
Pill Identification Wizard

Or this site:
Pill Identifier - Drugs.com

Shy, both links are to the same site. LOL

It's not on there anyway, I already tried.

Sorry, I hit the same one twice. But the other two I have does not list it either, unless it is a mylanta type but I would say it is.

The best thing to do is to call your local emergency room and ask or if you have a pharmacy still open, call there and ask. Also ask for the proper disposal method.

Mylan is Mylan Pharmaceuticals, but I could not even find it on their website.

I found something similar with the coloring and mylan but the number does not match. The number is 145 and one that is 4415 but not 4455. That is why people should search sites on their own, so they cannot say they got the wrong information. Drug and Pill Identifier - Medical University Of South Carolina

Thanks!

I don't know if there is a Physicians Desk Reference (PDR) in your local library, but that will give you an answer. However, if it is illegal you might try to find it on an illegal drug site, such as a police site.

IT doesn't seem to be a proper marking, check the pill again or just bring it to a pharmacy.
