OK, first, NEVER take anything you can't identify, obviously. But, if you really feel you need to know, try the link below, which is a "Pill Identification Wizard" site.

If you don't know what a pill is, you need to throw it away, rather than guess what it is. Many pills are similar in appearance. Asking what they are on THIS forum isn't very useful.

If in doubt - throw it out! Go on Physican's Desk Reference web site or to local library and look up pill pictures in the PDR. Do NOT take the pill - or allow anyone else to - if you can't identify what it is!

Ask a pharmacist...it would depend on what was in the formula

The Physicians Desk reference often called PDR has pictures of all pills. drugs.com may have it also

one answer:  Off-white capsule shaped tablet imprinted 377 is 50 mg tramadol, an analgesic.\n\n377 is generic Ultram (50 mg tramadol) made by Caraco.\n\n-There's some more if you check my source...

I would call a pharmacy.\nThe pill does not show up in drugs.com pill identifier.

Here's a website that will describe what the pill looks like and the imprint on it.  In order to find it, you'd have to have some idea what it is though.\n\nUPDATE:\nTry the second website I listed. It has a wizard to find the medicine by size/color/imprint. (I think it's biaxin?)

a current edition of "The Pill Book" or a current PDR (physicians Desk Referance) are quite handy. There are online pill checkers too. but they are hard to find and I lost the link.. if I find it again I'll post it in the comments

Might be a good  idea to call the Poison Control Center in your area or call nationally  at 1800 222-1222.  They have a huge data base and can tell you exactly what the pill is.  Pharmacies can do this as well but their data base isn't nearly as big.

Check this site:\nhttp://search2.drugs.com/imprints.php\n\nYou may have to play with the entries a bit, as what WE think of as white may be ivory, or what you see as US may be something else.

If I found a pill, I would wojnder what it was, then I would throw it away.\n\nIf someone tells you what they think it is: what are you going to do?\nTake it???\n\nI just wouldn't do that. I wouldn't take medication according to what some random stranger thought it was.\n\nDo yourself a favour and bin it.

if you don't know where the pill came from or what it is, don't take it.  Not sure of your age, but did you find this in a kid's room?\nIf the pill you found matches the image of MD 532, the pill is 20 mg methylphenidate (generic Ritalin), a drug used to treat ADHD and narcolepsy.\n (it is a peachy pink color)

It sounds like a generic Prozac (Flouxetine Hydrochloide). The imprint would be a b that looks a lot like a g, and if you found it on the ground it is likely that is what it is. \n\nAlso, it is generally not advised to handle unknown medications without gloves on as many pedications are easily absorbed through the skin. ;)
