It`s a blue, small, oval pill with the numbers 1721 with an emblem in front of it or it may be G.

If you found this and you know it is not yours, then you need to dispose of it safely. Calling your local Emergency Room and talking to a professional there or calling a pharmacy and talking to a registered pharmacist - either one could tell you the correct method of disposal. They may ask that you bring it in and they will take care of the disposal. If it were me, I could crush the tablet and throw it in the garbage, so no one else could find it and try to take something they know nothing about.

It's Alprazolam, an anti-anxiety medication
