Pill imprints are vital for identifying medications, but when an imprint like 'P 50' is reused across different drugs, careful attention to other details is crucial. An incorrect identification can lead to serious health complications, ranging from ineffectiveness for the intended condition to dangerous drug interactions or overdose. To correctly identify the pill, it is essential to consider not only the 'P 50' imprint but also the pill's color and shape, as this information is the key differentiator for at least three distinct medications.
The Brown, Round P 50 Pill: Diclofenac Sodium 50 mg
If you have a brown, round pill with the imprint 'P 50' on it, you are likely holding Diclofenac Sodium Delayed Release 50 mg. This is a prescription-only medication and a member of the nonsteroidal anti-inflammatory drug (NSAID) class.
Uses of Diclofenac Sodium 50 mg
Diclofenac works by reducing substances in the body that cause pain and inflammation. As an oral tablet, its uses include:
- Chronic Pain Management: Alleviates moderate-to-severe chronic pain.
- Back Pain: Provides relief for certain types of back pain.
- Ankylosing Spondylitis: Reduces inflammation and pain in the spine caused by this form of arthritis.
- Osteoarthritis and Rheumatoid Arthritis: Decreases symptoms like joint pain, stiffness, and swelling.
- Aseptic Necrosis: Treats pain associated with this condition, which results from a loss of blood supply to a bone.
Side Effects and Precautions for Diclofenac
Like all NSAIDs, Diclofenac carries a risk of side effects and should be used with caution.
- Common Side Effects: Nausea, vomiting, indigestion, stomach pain, headache, dizziness, and mild swelling.
- Serious Side Effects: Increased risk of heart attack or stroke, severe stomach bleeding, kidney damage, and liver problems. These risks can be life-threatening and require immediate medical attention.
Diclofenac Interactions and Warnings
Diclofenac has a boxed warning from the FDA due to its cardiovascular and gastrointestinal risks. Patients should be aware of potential interactions, including:
- Alcohol: Increases the risk of stomach bleeding.
- Blood Thinners: Increases the risk of bleeding.
- Fluconazole: Can increase the blood levels of diclofenac, potentially leading to increased side effects.
The Yellow, Round P 50 Pill: Pyridoxine Hydrochloride 50 mg
If your pill is yellow and round with the imprint 'P 50', it is identified as Pyridoxine Hydrochloride 50 mg, commonly known as Vitamin B6. It is classified as a vitamin and is not a controlled substance.
Uses of Pyridoxine Hydrochloride 50 mg
Pyridoxine is a vital nutrient for the body, playing a key role in metabolism, nervous system function, and blood cell formation. Its uses include:
- Dietary Supplementation: Addresses or prevents low levels of Vitamin B6.
- Pyridoxine Deficiency: Treats a diagnosed vitamin deficiency.
- Nausea and Vomiting: Used to relieve nausea and vomiting, especially during pregnancy.
- Nerve Damage Prevention: Helps prevent nerve damage associated with certain medications, such as isoniazid.
- Anemia: Addresses specific types of anemia where red blood cells do not form properly.
Side Effects and Precautions for Pyridoxine
While generally safe, high doses or long-term use of pyridoxine can lead to side effects.
- Common Side Effects: Nausea, headache, drowsiness, and numbness/tingling in the hands and feet.
- Peripheral Neuropathy: Long-term, high-dose use of Vitamin B6 can cause sensory nerve damage.
- Interactions: Can interact with medications for Parkinson's disease and tuberculosis.
The White, Round P 50 Pill: Fluconazole 50 mg
A white, round pill with the 'P 50' imprint is Fluconazole 50 mg, an azole antifungal medication. It is available by prescription to treat a variety of fungal infections.
Uses of Fluconazole 50 mg
Fluconazole works by inhibiting the growth of fungus and can be used for:
- Vaginal Yeast Infections: Treats infections caused by Candida species.
- Oral Thrush: Addresses fungal infections in the mouth and throat.
- Urinary Tract Infections: Fights Candida infections in the urinary tract.
- Systemic Fungal Infections: Manages more serious fungal infections like Candidemia.
- Prophylaxis: Can be used to prevent fungal infections in high-risk patients, such as those undergoing bone marrow transplants.
Side Effects and Precautions for Fluconazole
Fluconazole can cause side effects and requires careful monitoring, especially concerning liver function.
- Common Side Effects: Headache, nausea, diarrhea, stomach pain, dizziness, and rash.
- Serious Side Effects: Liver injury, including yellowing of the skin or eyes, dark urine, and severe allergic reactions.

Conclusion: The Importance of Professional Guidance
The imprint 'P 50' does not specify a single medication. It is a shared identifier for different drugs used for distinct medical purposes. Taking the wrong pill, even one with a matching imprint, can have serious consequences. If you are unsure about the identity of a pill you possess, do not take it. Your first step should always be to consult a pharmacist or another healthcare professional. Use online resources like Drugs.com's Pill Identifier to gather more information, but always confirm with a medical expert who can provide accurate guidance based on your health history. The risks associated with an unknown medication far outweigh any potential benefit from self-dosing.
Frequently Asked Questions
What should I do if I find an unlabeled pill with the P 50 imprint? Do not take the pill. Use a pill identifier tool online, like the one on Drugs.com, entering the imprint, color, and shape. Then, take the pill to a pharmacist or doctor for a professional verification. Never rely on visual identification alone.
Can a pharmacist help me identify a pill? Yes, pharmacists are highly trained to identify medications based on their appearance and can access databases with detailed information. They can also review your medication history to help prevent errors.
Is the 'P 50' pill a controlled substance? Based on the search results, none of the medications identified with the 'P 50' imprint (Diclofenac, Pyridoxine, Fluconazole) are controlled substances. However, this does not mean they are safe to take without professional guidance.
What if the color of my 'P 50' pill doesn't match the examples? If the color or shape of your pill differs from the common examples (brown, yellow, or white, round), it could be a different drug entirely or a variation produced by a different manufacturer. Contact a pharmacist for proper identification.
Is there an over-the-counter version of any 'P 50' pill? Pyridoxine Hydrochloride (Vitamin B6), which can appear as a yellow, round pill with a 'P 50' imprint, is available over-the-counter. Diclofenac and Fluconazole with this imprint are prescription medications.
Can I take a 'P 50' pill for any type of pain? No, because the imprint can correspond to different drugs, and only Diclofenac is an anti-inflammatory used for pain. Using the wrong medication, such as an antifungal or vitamin, will not relieve pain and could be harmful.
How can I avoid medication mix-ups at home? To prevent mix-ups, keep all medications in their original, clearly labeled containers. Regularly dispose of expired or unused medications safely. If you use a pill organizer, double-check that each pill is placed in the correct compartment.
