Ketoprofen may interact with other medications

Ketoprofen oral capsule can interact with other medications, vitamins, or herbs you may be taking. An interaction is when a substance changes the way a drug works. This can be harmful or prevent the drug from working well.

To help avoid interactions, your doctor should manage all of your medications carefully. Be sure to tell your doctor about all medications, vitamins, or herbs you’re taking. To find out how this drug might interact with something else you’re taking, talk to your doctor or pharmacist.

Examples of drugs that can cause interactions with ketoprofen are listed below.

Blood pressure drugs

Taking ketoprofen with these drugs may cause increased blood pressure. Examples of these drugs include:

  • angiotensin-converting enzyme (ACE) inhibitors
  • diuretics (water pills) such as furosemide or hydrochlorothiazide

Bipolar disorder drug

Taking lithium with ketoprofen can increase the level of lithium in your body. This may cause confusion, irregular heartbeat, and increased thirst. While you take ketoprofen, your doctor may monitor your kidney function to make sure you don’t have too much lithium in your system.

Disease-modifying antirheumatic drug

Taking methotrexate with ketoprofen can prevent methotrexate from leaving your body. This can increase the amount of methotrexate in your body and lead to side effects.

Gout or uric acid drug

Taking probenecid with ketoprofen can increase the level of ketoprofen in your body. This could cause more side effects from ketoprofen.

Anticoagulant, blood thinner

Taking warfarin with ketoprofen can increase your risk of stomach bleeding.

Nonsteroidal anti-inflammatory drugs (NSAIDs)

Taking ketoprofen with other NSAIDs may increase your risk of side effects, especially stomach pain, bleeding, or holes in your stomach. Examples of other NSAIDs include:

  • ibuprofen
  • naproxen

Disclaimer: Our goal is to provide you with the most relevant and current information. However, because drugs interact differently in each person, we can not guarantee that this information includes all possible interactions. This information is not a substitute for medical advice.

Ketoprofen warnings

This drug comes with several warnings.

Allergy warning

Ketoprofen can cause a severe allergic reaction. Symptoms may include:

  • trouble breathing
  • swelling of your face or throat
  • hives

If you develop these symptoms, call 911 or go to the nearest emergency room.

Don’t take this drug again if you’ve ever had an allergic reaction to it. Taking it again could be fatal (cause death).

Warnings for people with certain health conditions

For people with liver problems: Ketoprofen can increase certain liver enzymes and in some cases, it may damage your liver.

For people with asthma: Don’t use ketoprofen if you have aspirin-sensitive asthma. It could cause a fatal allergic reaction.

Warnings for other groups

For pregnant women: Ketoprofen is a category C pregnancy drug. That means two things:

  1. Research in animals has shown adverse effects to the fetus when the mother takes the drug.
  2. There haven’t been enough studies done in humans to be certain how the drug might affect the fetus.

Talk to your doctor if you’re pregnant or plan to become pregnant. This drug should be used during pregnancy only if the potential benefit justifies the potential risk.

If you become pregnant while taking this drug, call your doctor right away.

For women who are breastfeeding: It isn’t known if ketoprofen passes into breast milk and causes harm to your child. You and your doctor may decide whether you’ll take ketoprofen or breastfeed.

For seniors: Older adults may have reduced kidney function. Since ketoprofen is removed from the body by the kidneys, this may cause increased side effects. If you’re older than 75 years, your doctor may give you a lower dosage of ketoprofen and monitor your kidney function.

For children: It hasn’t been established that this drug is safe or effective for use in people younger than 18 years.
