Daypro (Generic Oxaprozin): Complete Medication Guide
Key Takeaways
Daypro (oxaprozin) is a nonsteroidal anti-inflammatory drug (NSAID) used to reduce pain, swelling, and stiffness from arthritis and other joint conditions.
The generic version works the same way as brand-name Daypro but typically costs significantly less.
Common side effects include stomach upset, heartburn, and dizziness; serious side effects are rare but require immediate medical attention.
This medication should be taken at the lowest effective dose for the shortest time possible to minimize health risks.
Always discuss your medical history and current medications with your doctor before starting oxaprozin.
Daypro (Generic Oxaprozin) Overview
Daypro, known generically as oxaprozin, is a nonsteroidal anti-inflammatory drug (NSAID) in the same family as ibuprofen and naproxen. It works by blocking chemicals in your body that cause inflammation and pain. Doctors typically prescribe oxaprozin to treat pain and stiffness from arthritis, including rheumatoid arthritis and osteoarthritis. The drug can also help with other types of joint pain and inflammation.
The generic version of Daypro contains the exact same active ingredient as the brand-name version. Many patients choose generic medications as a cost-effective alternative to brand-name drugs because they provide identical therapeutic benefits at a lower cost. Unlike some medications, oxaprozin only needs to be taken once or twice daily, which makes it convenient for people managing long-term pain conditions.
Oxaprozin is available as a tablet that you swallow by mouth. It typically begins working within a few hours, though some people may need to take it for several days or weeks before experiencing the full benefit. This information is educational and does not replace advice from your healthcare provider.
Side Effects
Oxaprozin is generally well-tolerated when taken as directed. Most side effects are mild and may decrease over time as your body adjusts to the medication. However, NSAIDs carry specific risks that you should understand before starting treatment.
Common Side Effects
Stomach upset or heartburn — Nausea, indigestion, or a burning sensation in your stomach may occur, especially if you take the medication without food. Taking oxaprozin with a meal or milk may help reduce this.
Dizziness or lightheadedness — Some people feel unsteady or dizzy when standing up quickly. Rise slowly from sitting or lying down to minimize this effect.
Headache — Mild to moderate headaches are possible and usually resolve without treatment.
Rash or itching — A mild skin reaction may develop in some individuals. This is typically not serious but should be monitored.
Constipation or diarrhea — Changes in bowel habits may occur; staying hydrated and eating fiber-rich foods can help.
Fatigue — Some people report feeling unusually tired when starting this medication.
Serious Side Effects
Stomach bleeding or ulcers — NSAIDs can cause serious gastrointestinal bleeding, especially with long-term use or in people over age 65. Signs include black or bloody stools, vomiting blood, or severe abdominal pain.
Allergic reaction — Though rare, some people experience swelling of the face, lips, or throat; difficulty breathing; or severe rash. This requires immediate medical attention.
Heart attack or stroke — Long-term NSAID use may slightly increase your risk, particularly if you have existing heart disease or high blood pressure.
Liver problems — Yellowing of the skin or eyes, dark urine, or severe fatigue may indicate liver damage.
Kidney issues — NSAIDs can affect kidney function, especially in people with existing kidney disease, diabetes, or dehydration.
When to Seek Medical Attention
Contact your doctor right away if you experience severe stomach pain, bloody stools, vomiting blood, chest pain, shortness of breath, sudden weakness, or swelling in your legs. These may indicate serious side effects that need urgent evaluation. You should also call if you develop a severe rash, yellowing of the skin or eyes, or signs of an allergic reaction like difficulty breathing.
If side effects are mild but persistent, discuss them with your healthcare provider at your next appointment. Do not stop taking oxaprozin without talking to your doctor first, even if you feel better, as sudden discontinuation may affect your condition.

Important: If you miss a dose, take it as soon as you remember unless it's almost time for your next dose. In that case, skip the missed dose and continue your regular schedule. Never take a double dose to make up for a missed one. Do not stop taking oxaprozin without your doctor's approval, as this may allow your condition to worsen. Your doctor may adjust your dose over time based on how well it works and any side effects you experience.
Drug Interactions
Oxaprozin can interact with certain medications and substances, potentially reducing its effectiveness or increasing side effects. Tell your doctor about all medications, supplements, and over-the-counter drugs you take before starting oxaprozin.
Blood Thinners (Warfarin, Dabigatran)
NSAIDs like oxaprozin may increase the bleeding risk when combined with blood thinners. Your doctor may need to monitor you more closely or adjust doses to keep you safe.
Blood Pressure Medications (ACE inhibitors, Beta-blockers)
Oxaprozin can reduce the effectiveness of blood pressure medications and may raise blood pressure. Your doctor may need to monitor your blood pressure more frequently.
Other NSAIDs (Ibuprofen, Naproxen, Aspirin)
Taking oxaprozin with other NSAIDs significantly increases the risk of stomach bleeding and kidney problems. Never combine NSAIDs unless specifically directed by your doctor.
Methotrexate (Arthritis and Cancer Medication)
Oxaprozin may increase methotrexate levels in your body, raising the risk of toxicity. Your doctor will monitor your blood work closely if you take both medications together.
Lithium (Bipolar Disorder Treatment)
NSAIDs can increase lithium levels, potentially causing harmful side effects. Your doctor may adjust your lithium dose or monitor lithium levels more frequently.
Corticosteroids (Prednisone, Dexamethasone)
Combining oxaprozin with corticosteroids significantly increases your risk of stomach bleeding and ulcers. Your doctor will weigh the benefits against the risks if both are necessary.
