The Challenge of Pill Identification with the 'P50' Imprint
When you find an unmarked pill or need to confirm your medication, the imprint is the most helpful clue. However, a specific code like 'P50' can be a red herring, as several different drug manufacturers can use the same or a similar imprint on entirely different drugs. Relying on the imprint alone can lead to dangerous mix-ups. To accurately identify a pill and determine what the pill P50 is used for, you must cross-reference the imprint with other visual characteristics, such as color, shape, and size. This article will break down the common drugs associated with the P50 and P 50 imprints.
P 50: Diclofenac Sodium 50 mg (Brown, Round)
One of the most frequently cited pills with the imprint 'P 50' is Diclofenac Sodium in a 50 mg delayed-release tablet. This medication is a nonsteroidal anti-inflammatory drug (NSAID) and belongs to the same class as ibuprofen and naproxen.
Common Uses:
- Back pain
- Ankylosing Spondylitis
- Osteoarthritis
- Rheumatoid Arthritis
- Chronic pain
- Aseptic Necrosis
- Menstrual cramps (brand Cataflam)
Important Considerations: Diclofenac carries serious warnings, including an increased risk of heart attack, stroke, and gastrointestinal bleeding. It is also not recommended for use just before or after heart bypass surgery.
P50: Prednisone 50 mg (White, Round)
Another common tablet bearing a 'P50' imprint is Prednisone 50 mg, a white, round pill. This is a potent glucocorticoid used to treat a wide range of conditions involving inflammation.
Common Uses:
- Severe allergic reactions
- Acute Lymphocytic Leukemia
- Adrenocortical Insufficiency
- Adrenogenital Syndrome
- Ankylosing Spondylitis
- Management of certain cancers
Important Considerations: Prednisone use requires careful medical supervision, especially at high doses or for extended periods. Potential side effects include fluid retention, high blood pressure, mood changes, and immune system suppression.
P50: Promethazine Hydrochloride 50 mg (White, Round)
A white, round tablet with the imprint 'P50' can also be Promethazine Hydrochloride 50 mg. This medication is in a different drug class than Prednisone, further highlighting the importance of noting all pill characteristics.
Common Uses:
- Seasonal and perennial allergic rhinitis
- Allergic reactions and anaphylaxis
- Light sedation
- Nausea and vomiting
- Motion sickness
P50: Diphenhydramine Hydrochloride 50 mg (Blue, Capsule/Oblong)
If the pill is a blue, oblong capsule with 'P50' imprinted, it is likely Diphenhydramine Hydrochloride 50 mg. This is an antihistamine available over-the-counter and by prescription.
Common Uses:
- Allergic reactions and rhinitis
- Treatment of insomnia
- Relief of cold symptoms like sneezing and runny nose
P 50: Pyridoxine Hydrochloride 50 mg (Yellow, Round)
Finally, a yellow, round tablet marked 'P 50' is Pyridoxine Hydrochloride 50 mg, a form of Vitamin B6.
Common Uses:
- Dietary supplementation
- Treatment of certain seizures and vitamin deficiencies
Comparison of P50 Medications
To help differentiate between the various drugs that use the P50 or P 50 imprint, consult the table below. This reinforces the need to consider all features, not just the code.
| Imprint | Color | Shape | Drug Name | Drug Class | Primary Uses |
|---|---|---|---|---|---|
| P 50 | Brown | Round | Diclofenac Sodium 50 mg | NSAID | Pain and inflammation |
| P50 | White | Round | Prednisone 50 mg | Glucocorticoid | Severe inflammation, allergies |

Safe Pill Identification Practices
Given that a single imprint can correspond to several different medications, here is a list of best practices for identifying any pill you encounter:
- Examine All Features: Note the imprint, but also the color, shape, and whether it has a score line or not. These details are crucial for differentiation.
- Use Reputable Online Tools: Websites like Drugs.com offer reliable pill identifier tools where you can input multiple features to narrow down the results.
- Always Consult a Professional: The most reliable and safest method is to consult a pharmacist or your prescribing physician. They have the expertise to confirm a pill's identity based on your medical records.
- Verify Changes in Appearance: If you receive a prescription refill where the pill looks different, don't assume it's the same medication. Double-check with your pharmacy before taking it.
- Never Self-Diagnose: Based on a search, you may think you have identified a pill, but without professional confirmation, you could be mistaken. Taking the wrong medication can have serious health consequences.
Conclusion: Always Verify with a Professional
In summary, the question of "what is the pill P50 used for?" has no single, simple answer. The imprint alone is insufficient for positive identification and can lead to dangerous health decisions. The mark could belong to an anti-inflammatory like Diclofenac, a powerful steroid like Prednisone, or even a vitamin supplement. The only responsible course of action is to use all available visual clues and, most importantly, confirm your findings with a qualified healthcare provider. Your health and safety are paramount, so always verify your medication with a professional.
