Pill Identification from a Doctor's Perspective

Medical Author:

In the emergency room where I work, I sometimes see patients who have either taken the wrong medication or the wrong dose of medication. It is a common problem. Medication errors can cause serious consequences. Doctors and pharmacists are diligent in making sure patients receive the correct medication. But mistakes happen. As a consumer, you need to protect yourself and ensure you have the correct medication. Know the medication and dose you should have received, and understand your condition.

The RxList Pill Identifier Tool will help you identify generic and brand name drugs by pill color, size, shape, and drug imprint. Match your Pill ID to the pictures and quickly identify your medications. If you do not find a match, call your doctor or pharmacist.

How To Use the RxList Pill Identifier/Pill Finder Tool

To accurately identify the pill, drug or medication, you can do any one, any combination of or all of the following steps using our pill identifier tool.

  • Enter the imprint code on the medication, (example the numbers and/or the letters on the side of the pill or tablet).
  • Select the color of the pill in the pull-down menu above.
  • Select the shape of the pill in the pull-down menu above.

Once you've found a drug id match, you'll be able to link to a detailed description, drug picture, and images in our comprehensive RxList Drug Database. You can also use the drug pictures to help identify pills.
