Decoding the 'A 50' Imprint
Encountering a pill with the imprint 'A 50' or 'A50' can be confusing, as multiple medications use this marking. The key to accurate identification lies in combining the imprint code with other physical characteristics like color, shape, and size. Because some of these medications are potent or classified as controlled substances, it is vital to identify them correctly and never take a pill that you cannot positively confirm.
The Opioid Analgesic: Oxycodone
One of the most notable medications with an 'A 50' imprint is Oxycodone Hydrochloride, specifically a gray, round tablet marked 'A 50'.
Oxycodone Characteristics:
- Imprint: 'A 50'
- Color: Gray
- Shape: Round
- Drug Class: Opioid (narcotic analgesic)
- Use: Management of moderate to severe pain
- Controlled Substance: Yes, classified as a Schedule II controlled substance due to its high potential for abuse and dependence.
Oxycodone is a powerful painkiller that works by binding to opioid receptors in the brain to block pain signals. Due to its high risk for addiction and overdose, it is essential to handle this medication with extreme caution and only as prescribed by a healthcare professional. Side effects can include drowsiness, constipation, nausea, and dizziness.
The Beta-Blocker: Metoprolol
Another medication that can be marked 'A50' is Metoprolol Succinate, an extended-release tablet used to treat various heart conditions. The 'A' and '50' may or may not be separated by a score line, depending on the manufacturer.
Metoprolol Characteristics:
- Imprint: 'A50'
- Color: White
- Shape: Round
- Drug Class: Cardioselective beta-blocker
- Use: Treatment of high blood pressure, angina (chest pain), and heart failure
- Controlled Substance: No
Metoprolol works by blocking the effects of certain natural chemicals in the body, like epinephrine, on the heart and blood vessels. This lowers heart rate, blood pressure, and strain on the heart, making it effective for treating heart-related issues. It is important to follow a doctor's instructions for dosage, as abruptly stopping this medication can lead to serious health problems.
The Angiotensin Receptor Blocker (ARB): Losartan
A white, oval pill imprinted with 'A50' is Losartan Potassium. This medication is used to treat high blood pressure and other related conditions.
Losartan Characteristics:
- Imprint: 'A50'
- Color: White
- Shape: Oval
- Drug Class: Angiotensin receptor blocker (ARB)
- Use: Treatment of high blood pressure and protection against kidney damage in patients with diabetes
- Controlled Substance: No
Losartan works by relaxing blood vessels so that blood can flow more easily. This lowers blood pressure and reduces the workload on the heart. As with any blood pressure medication, a doctor's guidance is essential to manage dosage and monitor for side effects like dizziness and fatigue.
Other Potential Medications with Similar Codes
While Oxycodone, Metoprolol, and Losartan are the most common, other medications may have similar imprints or variations. For example, a pink, round pill with 'A 50' is Anzemet (dolasetron), used to prevent nausea and vomiting. It is crucial to verify not just the imprint, but also the shape and color to avoid a mix-up.

| Controlled | Yes (Schedule II) | No | No |
| Primary Uses | Pain management | High blood pressure, angina, heart failure | High blood pressure, diabetic kidney disease |
The Critical Importance of Safe Identification
Accurate pill identification is critical for preventing medication errors, especially given that one of the pills with an 'A 50' imprint is a powerful, addictive opioid. Never consume a medication that you cannot definitively identify. If you find an unmarked or unverified pill, take the following steps:
- Do not ingest the pill. This is the most important safety rule. Accidental ingestion, especially by children, can have fatal consequences.
- Consult a professional. Take the pill to a pharmacist or doctor for identification. They have access to official drug databases and can provide a definitive answer.
- Use an online pill identifier tool responsibly. Websites like Drugs.com offer reliable pill identifiers where you can enter the imprint, color, and shape to narrow down possibilities. However, this should not replace professional medical advice.
- Safely dispose of the pill. If the pill is not your prescribed medication, follow guidelines for proper drug disposal. Many pharmacies offer secure drop-off programs for unwanted medications.
Conclusion
The question, "What is a pill that says a 50?" has no single answer, highlighting the dangers of relying solely on an imprint. The code 'A 50' or 'A50' can correspond to multiple different drugs with vastly different uses and risks, including the opioid painkiller Oxycodone, the beta-blocker Metoprolol, and the ARB Losartan. By paying close attention to a pill's specific characteristics and consulting healthcare professionals, you can ensure safe medication practices and prevent potentially life-threatening errors.
For more information on pill identification and safe medication practices, consult a reputable source like the National Institutes of Health (NIH) or a licensed pharmacist.
