Ketoprofen (kee toe PROE fen) is a generic medication prescribed to lower inflammation (swelling) and pain in certain conditions. Ketoprofen belongs to a group of drugs called nonsteroidal anti-inflammatory drugs.

The Food and Drug Administration (FDA) has approved ketoprofen for use in people with:

• rheumatoid arthritis 
• osteoarthritis 
• pain 
• menstrual cramps and pain

These approved uses differ based on the form of ketoprofen your doctor prescribes.

Boxed warnings

Ketoprofen has boxed warnings about the risks of serious heart and blood vessel problems and serious digestive problems. Boxed warnings are the most serious warnings from the Food and Drug Administration (FDA). 

For details, see the “Interactions and warnings for ketoprofen” section.

Common questions about ketoprofen

Below you’ll find answers to a few commonly asked questions about ketoprofen.

Does ketoprofen come as a topical gel or topical patch?

No, ketoprofen does not come as a topical gel or topical patch. (Topical products are applied to your skin.) These forms have been discontinued and are no longer approved by the Food and Drug Administration (FDA). 

The only available forms are the ketoprofen oral capsule and the ketoprofen extended-release (ER) oral capsule. (With extended-release, the drug is released over time in your body.)

If you have questions about the forms of ketoprofen, talk with your doctor or pharmacist. 

Is ketoprofen similar to ibuprofen?

Yes. Both ketoprofen and ibuprofen (Advil, Motrin) belong to the group of drugs called nonsteroidal anti-inflammatory drugs (NSAIDs). These drugs work by reducing pain and inflammation (swelling). 

Ketoprofen is a generic drug that’s only available by prescription. Ibuprofen can be purchased over the counter and is available as a generic or brand-name version. Your doctor can also prescribe ibuprofen as a prescription drug.  

A generic medication is an identical copy of the active drug in a brand-name medication. (An active drug is the ingredient that makes a medication work.) Generic drugs are believed to be as effective and safe as brand-name drugs. And generic drugs typically cost less compared to brand-name drugs.

If you have questions about how these medications compare, talk with your doctor or pharmacist. 

How does ketoprofen work? And how long does it take to start working?

Ketoprofen belongs to a group of drugs called NSAIDs. It works by reducing pain and inflammation. It does this by lowering prostaglandin levels in the body, which eases inflammation. (Prostaglandins are substances that can increase your body’s inflammatory response.)

Ketoprofen oral capsule starts to relieve symptoms after 30 minutes. Ketoprofen ER oral capsule can take around 2–3 hours before you notice relief. 

If you’d like to know more about this, talk with your doctor or pharmacist.

Uses of ketoprofen

The Food and Drug Administration (FDA) approves prescription drugs such as ketoprofen for certain conditions. Approved uses for ketoprofen are described below. These uses differ based on the form of ketoprofen prescribed.

Use for certain types of arthritis

Doctors may prescribe ketoprofen oral capsule or oral extended-release (ER)* capsule for treating certain types of arthritis. These include rheumatoid arthritis and osteoarthritis. It’s used for this purpose in adults. It’s usually prescribed as a long-term treatment.

Rheumatoid arthritis is an autoimmune condition that causes inflammation (swelling) and pain in the joints. The whole body can be affected, and symptoms can be mild or severe. Symptoms can get better or worse during periods of remission (times when symptoms ease). 

Osteoarthritis is a chronic (long-term) joint condition. Symptoms may include joint pain and stiffness, decreased range of motion, and inflammation. This condition is usually caused by normal wear and tear to the joints, an injury, or getting older. 

Doctors may not prescribe ketoprofen ER oral capsule in certain situations, such as for acute (sudden) pain.

* With extended-release, the drug is released over time in your body.

Use for pain

Doctors may prescribe ketoprofen oral capsule for treating different types of pain. It’s used for this purpose in adults. It’s usually prescribed as a short-term treatment.

Pain is described as an uncomfortable sensation in the body. Each person experiences pain differently, and there are several types of pain, such as acute (sudden), chronic (long-term), and neuropathic (nerve-related).

With painful menstrual cycles, you may experience severe pain, cramping, and discomfort. These severe symptoms may cause you to miss work or school or perform daily activities.
