All prescription and over-the-counter drugs sold in the US are required by law to be uniquely identifiable by their imprint, shape and color. However, many pills are notoriously difficult to identify. This is especially true for OTC pill imprints and foreign drugs.
For all the pill identification ‘gurus’ out there (and anyone else who just happens to have the same pill on hand or knows what it is), we are assembling a list of unidentified drug imprints that have been submitted to this and other forums.
Please respond below if you can identify or provide any clues regarding these medications. Often simply knowing the originating country, intended use or manufacturer can considerably narrow down the search.

Thanks for the new forum. This is great having a permanent list of unidentified pill imprints so I don't have to look through my notes every day. BTW, I have a few 'mystery meds' to contribute if that's okay.
Regarding the pink pill with two interlocking squares, a poster on another board described the squares as overlapping each other like how you would draw a cube. He also suggested this pill is from Mexico and might be OxyContin. He may have meant oxycodone. But I don't think OxyContin or oxycodone is available in Mexico at present unless it's imported from the US or the UK.
canadian codine genaric no tylonol same strength
Hi bestdadat21,
Which mystery imprint is Canadian generic codeine?
Thanks.
Was searching for this to ID it as well, but that's after I got it in the mail on purpose after ordering Codeine through an online pharmacy.
This is ok for me as I am in Canada and its without perscription in small doses.
I believe this one has 10mg of Codeine, and no paracetol or acetomeniphen (spelling's bad, I know)...
that may explain another poster's offhanded comment to the same effect on the sites "most wanted" list which had its picture...
After taking one for mild pain (knee injury) I have no reason to believe its viagra at all, as had been conjectured before, because I did experience some slight analgesic effects.
Hope this helps.
Please do not post anything in this thread unless it relates to the mystery imprints listed at the top of the page.
Please start a new forum post for your pill identification requests.
Thank you for your cooperation.

Oblong white tablet marked MS or SW both sides
MS imprint is Contac Cold + Flu containing 5 mg phenylephrine and 500 mg acetaminophen.
Had also responded in another thread before I saw this one.
The pink micron pill is 10mg of codeine. I have some that I just picked up from a pharmacy in India. Since they didn't come in a blister pack I asked for proof of what they were and the guys showed me the large plastic micron labeled bottle they came from.
possibly Immodium Advanced Oral....
IMO imprint is not imodium.

The photographer clearly states the tablet contains zopiclone.
I asked if my serbian diazepam was legit and got slammed!Is the US full of bullies??
forget that this is the World Wide Web.
There are some old threads that speculated this was diazpeam.
It is analyzed and confirmed to be diazepam.
Not quantitated, so dosage unkown.
Manufacturer / country of origin also still unkown.
Blue triangular pill imprinted with "W"
A friend of mine (not one of the brightest crayons in the box) recently ordered phentermine online. The pill's she received are the same as the pill on the "Most Wanted" list. She said they came vaccuum sealed in one of those food saver bags. I dont know where she ordered them from exactly, but the return address was from Pakistan. I know thats not any kind of definitive ID, but might send some of the more clever & seasoned pill ID'ers like Goat or Kirby in the direction to finding one.

4N6, thank you so much for the confirmation.
Several old posts state the round blue tablet is a foreign diazepam (probably 10 mg), and we appreciate the confirmation of the chemical compostion.

I'll keep my eye open for these.
