What Is the White Pill With the M367 Imprint?

Finding an unidentified pill can be concerning, and it is important to approach such discoveries with caution. Recognizing its markings, such as “M367,” is crucial for identification and safety. Proper identification helps prevent misuse and potential health risks.

Identifying the M367 Pill

A white, capsule-shaped or oblong pill with the imprint “M367” on one side is a combination medication containing Hydrocodone Bitartrate and Acetaminophen. This imprint typically indicates a dosage of 10 milligrams (mg) of hydrocodone bitartrate and 325 mg of acetaminophen. The pill often has a bisecting line on the reverse side, allowing for easier division if a prescriber instructs a smaller dose.

This medication is manufactured by Mallinckrodt Pharmaceuticals. Hydrocodone is an opioid pain reliever, and acetaminophen is a non-opioid pain reliever and fever reducer. Their combination provides pain relief.

Common Medical Uses

The M367 pill, a combination of hydrocodone bitartrate and acetaminophen, is primarily prescribed for moderate to moderately severe pain. Healthcare providers may prescribe it for pain that has not responded adequately to less potent pain relievers. This can include discomfort following surgical procedures, pain resulting from injuries, or pain associated with chronic conditions like arthritis.

Hydrocodone, an opioid analgesic, works by interacting with opioid receptors in the central nervous system, altering how the brain and body perceive pain signals. Acetaminophen contributes to pain relief through a different mechanism, potentially inhibiting prostaglandin synthesis. Its inclusion can also enhance hydrocodone’s pain-relieving effects.

Safe Handling and Next Steps

Discovering an unprescribed or unidentified medication, such as a pill with the M367 imprint, carries inherent risks due to its potent ingredients. Taking medication not specifically prescribed to you can lead to unexpected side effects, adverse drug interactions, or accidental overdose. Never share prescription medications with others, as what is safe for one person may be harmful to another. The presence of hydrocodone, an opioid, means this medication has specific handling and disposal considerations.

The safest method for disposing of unused or expired medications is to utilize drug take-back programs. Many pharmacies, law enforcement agencies, and community programs offer permanent collection sites where medications can be dropped off securely. The U.S. Drug Enforcement Administration (DEA) also hosts periodic National Prescription Drug Take Back events.

If a take-back option is not readily available, and the medication is on the FDA’s “flush list,” flushing it down the toilet is an option to prevent accidental ingestion. For medications not on the flush list, mix them with an unappealing substance like dirt, used coffee grounds, or cat litter, seal the mixture in a plastic bag, and then discard it in the household trash. Always remove personal information from prescription labels before disposal. If accidental ingestion occurs or there is uncertainty about a prescription, consult a healthcare professional.
