Drug Facts
Generic Name: Oxaprozin

Daypro is sometimes used off-label to:

Common Side Effects

- Constipation
- Diarrhea
- Dizziness
- Gas
- Heartburn
- Nausea

Severe Side Effects
The United States Food and Drug Administration (FDA) has issued two boxed warnings for Daypro. Boxed warnings are the agency’s strongest warnings for serious and potentially life-threatening risks. Review these warnings and discuss any concerns you have with your healthcare provider before starting treatment:
- NSAIDs, like Daypro, increase the risk of serious heart problems, including heart attack and stroke, which can lead to death. Do not take NSAIDs before or after a heart surgery called a coronary artery bypass graft (CABG). Let your healthcare provider know about all your heart conditions (including a recent heart attack) and only use NSAIDs if your healthcare provider tells you to.
- NSAIDs may cause serious intestinal (GI) adverse events including bleeding, ulcers, and tears in the esophagus, stomach, or intestines. These effects can occur at any time during treatment, and you may not notice any warning signs or symptoms. In some cases, NSAID-related bleeding has led to death.
Daypro can cause severe side effects, which can sometimes be life-threatening. Call your healthcare provider right away if you develop any severe reactions. Call 911 if your symptoms feel life-threatening or you think you’re having a medical emergency.
Serious side effects and their symptoms include:
- Cardiovascular thrombotic events (heart attack and stroke): Get medical help right away if you develop chest pain, shortness of breath, weakness on one side of your body, or slurred speech.
- GI bleeding, ulceration, and perforation (bleeding, ulcers, or tears in the esophagus, stomach, or intestines): Let your healthcare provider know if you have stomach pain, indigestion, or you vomit blood. Report any blood in your stool or if your stool is black and sticky like tar.
- Hepatotoxicity (liver problems): Symptoms of a liver injury include nausea, weakness, tiredness, itching, diarrhea, yellowing of the skin or eyes, flu-like symptoms, and pain in the upper right side of your abdomen.
- Heart failure: Contact your healthcare provider if you develop unexplained weight gain, swelling in your legs, arms, hands, or feet, or shortness of breath.
- Anaphylactic reactions (life-threatening allergic reactions): Get medical help immediately if you develop signs of an allergic reaction, including swelling of the face or throat or difficulty breathing.
- Life-threatening skin reactions: Stop taking Daypro if you develop a rash, blisters, or fever, and call your healthcare provider right away.
- Hypertension (new or worse high blood pressure)
- Kidney problems: Your healthcare provider will monitor how well your kidneys are working, especially if you have risk factors for kidney problems.
- Anema (low red blood cells)

Dosage: How Much Daypro Should I Take?
Modifications

The use of Daypro should be limited during 20 to 30 weeks of pregnancy. If you use Daypro for longer than 48 hours during this time, your healthcare provider may need to monitor the amount of fluid in your womb around your baby. Be sure to let your healthcare provider know if you are pregnant or plan to become pregnant before starting Daypro.

Many other NSAIDs are available to help treat the symptoms of arthritis. Most NSAIDs need to be taken multiple times per day to provide 24-hour pain relief. Daypro has the advantage of being long-acting, so you typically only need to take one dose per day.
Other NSAIDs include:
- Celebrex (celecoxib)
- Diclofenac (Lofena, Cataflam)
- Advil or Motrin (ibuprofen)
- Aleve or Naprosyn (naproxen)
This is a list of NSAIDs also used to treat arthritis. It is NOT a list of drugs recommended to take with Daypro. In fact, you should not use these drugs together. Ask your healthcare provider or pharmacist if you have any questions about your medicines.
