You can take oxaprozin (Coxanto) with or without food. But you're recommended to take it with food or milk because doing so can help prevent stomach irritation.
Don't crush, chew, or open the oxaprozin (Coxanto) capsules. If you're having trouble swallowing the capsules, contact your healthcare team. You might need to be switched to a different medication.
Avoid drinking alcohol while taking oxaprozin (Coxanto). Doing so can raise your risk for stomach bleeds and stomach ulcers.
Don't take oxaprozin (Coxanto) with other NSAIDs, such as ibuprofen (Motrin, Advil). Doing so puts you at higher risk for side effects, including stomach bleeds. NSAIDs are commonly found in over-the-counter pain and cold medications. Talk with your pharmacist if you're not sure whether you're already taking an NSAID.
Oxaprozin (Coxanto) can interact with many medications, including blood pressure medications, blood thinners (including aspirin), and certain steroids. Tell your healthcare team about all of the medications you're taking or planning to take before starting oxaprozin (Coxanto). They can make sure your medications are safe for you to take together.
Oxaprozin (Coxanto) can make your skin more sensitive to the sun or ultraviolet (UV) light. This means you can get more sunburns than usual. To protect your skin, make sure to wear sunscreen when going outside and wear long-sleeved clothing. If possible, avoid being exposed to light or sun for a long time.
Store oxaprozin (Coxanto) up and away from children and pets so they're less likely to reach and accidentally take the medication. If you think your child accidentally took the medication, call a Poison Control Center right away at 1-800-222-1222.
Oxaprozin (Coxanto) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.

Oxaprozin (Coxanto), like all NSAIDs, raises your risk for stomach ulcers (sores) and bleeds. Stomach bleeding is a dangerous condition that requires treatment right away. There are many conditions and medications that raise your risk of this problem, so speak with your healthcare team before starting oxaprozin (Coxanto). Stomach bleeding and ulcers can occur without warning or symptoms, so it's best to take the lowest possible dose of oxaprozin (Coxanto) for the shortest possible time to minimize your risk.

Oxaprozin (Coxanto) can raise your risk of having blood clots, which can cause a heart attack or stroke. Your healthcare team will prescribe the lowest dose of oxaprozin (Coxanto) for the shortest period of time possible to minimize your risk of blood clots. If you have heart problems, talk to your healthcare provider before starting this medication. Don't take oxaprozin (Coxanto) if you had, or will have, heart surgery. Call 911 or get medical help right away if you experience chest pain, shortness of breath, weakness on one side of your body, or trouble speaking or walking.
Risk factors: Heart problems
Oxaprozin (Coxanto) can cause your body to hold onto extra fluid, which can raise your blood pressure or put you at risk for heart failure. Tell your healthcare team if you have a history of heart problems or are taking blood pressure medications before starting oxaprozin (Coxanto) to make sure it's safe for you. They might ask you to check your blood pressure more often while you're taking oxaprozin (Coxanto) and adjust the dose of your blood pressure medications as needed. If you experience unexplained fainting, chest pain with physical activity, or irregular heartbeat while taking oxaprozin (Coxanto), contact your healthcare team.
Risk factors: Older adult | Kidney or liver problems | Heart failure | High blood sugar | Sepsis | Having high amounts of certain proteins in blood (paraproteinemia) | Not enough fluids in the body (dehydration) | Taking other medications that can cause kidney problems
Oxaprozin (Coxanto) can cause kidney problems. Your risk is higher if you have certain factors like older age, certain medical problems like diabetes, or you're taking medications that can cause kidney problems. Your healthcare team might order blood tests to monitor your kidney health before and during treatment with oxaprozin (Coxanto). If your kidney health worsens, your provider might stop your oxaprozin (Coxanto) treatment. Contact your provider if you develop any signs or symptoms of kidney failure, including changes in your need to urinate, tiredness, dry and itchy skin, low appetite, and muscle cramps.
Risk factors: History of liver problems
Although rare, oxaprozin (Coxanto) can cause serious liver problems, which can be life-threatening. Get medical attention right away if you notice swelling of your stomach, stomach pain, yellowing of your skin or the whites of your eyes, stool changes (black, tarry, or bloody stools), nausea, vomiting, confusion, or dark or brown urine. Your healthcare team will ask you to stop taking oxaprozin (Coxanto) while they check your liver health.
Risk factors: Aspirin allergy | NSAID allergy
Severe allergic reactions to oxaprozin (Coxanto) are possible, including life-threatening reactions like facial swelling, shock, and anaphylaxis. Let your healthcare team know if you have an allergy to aspirin or other NSAIDs before starting oxaprozin (Coxanto). If you notice hives, rash, red skin, swelling of the lips or tongue, or difficulty breathing after using oxaprozin (Coxanto), call for medical help as soon as possible.
Although rare, oxaprozin (Coxanto) can cause serious skin reactions called Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), or drug reaction with eosinophilia and systemic symptoms (DRESS). If you notice changes in your skin, such as rash, blisters, skin reddening, or skin peeling, stop using oxaprozin (Coxanto) and get medical attention right away.
If you're pregnant, talk to your healthcare team first about the risk and benefits of oxaprozin (Coxanto) before using this medication. Oxaprozin (Coxanto) can cause harm to your unborn baby or complications during delivery if taken during the second half of pregnancy.
