Pill Identification from a Doctor's Perspective
Medical Author: John P. Cunha, DO, FACOEP
In the emergency room, I have seen patients who have either taken the wrong medication or the wrong dose of medication. Medication errors are a common problem that can cause serious consequences. Doctors and pharmacists are diligent in making sure patients receive the correct medication, but mistakes can 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 medical conditions.
The RxList Pill Identifier Tool will help you identify prescription, over-the-counter (OTC), generic, and brand name drugs by pill color, size, shape, and drug imprint. Match your drug imprint (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 Identification Tool.
- The imprint is the letters, numbers or other markings on the pill, tablet or capsule. If there are different markings on the front of back, try entering just one side. If you want to enter both, separate them with by using the symbol * (i.e.: Lupin*10).
- 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.
