There is a good chance it is Swift Non-Aspirin 500mg of Acetominophin.
However, I am not a pharmacist, so don't rely on this information.
If in doubt, dispose of the pills or consult a qualified pharmacist.
If the imprint is S21, this pill is PENICILLIN V POTASSIUM 500 MG.
Can you explain the colour of the pill, and where the imprints are located, and if there is any scoring on the tablet?
The pill with the imprint 4839 is Acetaminophen-Oxycodone. Acetaminophen-Oxycodone is used for the treatment of pain and is classified as a narcotic.
It is impossible to identify this pill without the imprint code found on the medication.
Generic for Keppra, an anti-convulsant----WILL NOT GET YOU HIGH.
