Blue Round Pill: What Could It Be?
Found a blue round pill and not sure what it is? Blue round tablets include several common prescription medications — but this combination is also frequently counterfeited. The only reliable way to identify a specific pill is its imprint code. Below are the most commonly encountered blue round pills, followed by an important counterfeit warning and the PillID identifier tool.
⚠ COUNTERFEIT WARNING: Blue round pills stamped with "M 30" (mimicking oxycodone 30mg) are among the most commonly counterfeited drugs in the United States. The DEA reports that the vast majority of counterfeit M 30 pills contain illicit fentanyl. Do not consume any blue round pill you cannot verify through a licensed pharmacy. If you suspect fentanyl exposure, call 911 immediately.

Look carefully at both surfaces of the pill for an imprint code — letters, numbers, or logos pressed into the tablet. Record every character exactly. Blue round pills often carry controlled substance imprints, so precision matters when entering the code into the identifier.
Use PillID's tool above, entering the imprint along with "blue" and "round." If the result returns a controlled substance, verify that the pill came from a licensed pharmacist filling a valid prescription. Do not assume a pill is genuine based on appearance.
Because the blue round tablet form has been heavily exploited by counterfeiters producing fentanyl-laced pills, any blue round pill obtained outside of a licensed pharmacy should be treated as potentially dangerous. Fentanyl test strips are available in many communities and can detect fentanyl contamination. For emergencies, call 911. For poison inquiries, call 1-800-222-1222.
Counterfeit Blue Pills and Fentanyl Risk
Since approximately 2019, illicit drug markets have been flooded with counterfeit pills designed to look like legitimate prescription medications. Blue round pills are among the most targeted — particularly those mimicking oxycodone 30mg (M 30) and other opioids. The DEA's "One Pill Can Kill" campaign highlights that a single counterfeit pill containing fentanyl can be lethal. No visual inspection, including color, shape, or imprint appearance, can determine whether a pill is genuine or counterfeit. Only laboratory testing can confirm a pill's contents.
