Celebrex (celecoxib) is a brand-name prescription drug used to treat the following conditions in certain people:

As with other medications, Celebrex can interact with certain other drugs. An interaction occurs when one substance causes another substance to have a different effect than expected.

For details about Celebrex’s interactions, keep reading. For additional information about Celebrex, including details about its uses, see this article.

In some cases, a factor or condition could prevent your doctor from prescribing Celebrex due to the risk of harm. This is known as a contraindication. The contraindications of Celebrex include:

Planning to have or having recently had heart bypass surgery

Celebrex belongs to a class of drugs called nonsteroidal anti-inflammatory drugs (NSAIDs). Taking an NSAID can increase your risk of serious, potentially life threatening cardiovascular problems such as heart attack and stroke.*

Due to this risk, doctors typically will not prescribe Celebrex if you’re due to have or have recently had a coronary artery bypass graft (CABG). This is a type of heart bypass surgery. Taking Celebrex for pain after CABG can increase the risk of heart attack and stroke. Ask your doctor about other treatments that may be better choices for you.

* Celebrex has a boxed warning for this side effect. A boxed warning is the most serious warning from the Food and Drug Administration (FDA). To learn more, see “Boxed warnings” above.

Having had an allergic reaction to sulfonamides

Celebrex is related to sulfonamide medications, such as trimethoprim/sulfamethoxazole (Septra, Bactrim), sulfasalazine (Azulfidine), and dapsone. Celebrex’s manufacturer recommends that people avoid taking Celebrex if they’ve had an allergic reaction to a sulfonamide medication. This is because taking Celebrex could cause another allergic reaction. However, doctors sometimes prescribe Celebrex to people with a sulfa allergy on a case-by-case basis.

If you’ve had an allergic reaction to sulfonamides, talk with your doctor about whether Celebrex is right for you.

Having had an allergic reaction to other NSAIDs

Celebrex is a type of drug called an NSAID. If you’ve had an asthma attack, hives, or other allergic reaction after taking a different NSAID, your doctor will likely not prescribe Celebrex. This is because taking Celebrex could cause another allergic reaction.

Examples of other NSAIDs include aspirin, ibuprofen (Advil, Motrin), and naproxen (Aleve, Naprosyn). Your doctor can recommend other treatments that may be better choices.

Having had an allergic reaction to Celebrex or any of its ingredients

If you’ve had an allergic reaction to Celebrex or any of its ingredients, your doctor will likely not prescribe Celebrex. Taking the drug could cause another allergic reaction. You can ask your doctor about other possible treatments.

Before taking Celebrex, it’s important to tell your doctor if any of these contraindications apply to you. They can determine whether to prescribe Celebrex.

Alcohol is not known to interact with Celebrex. Alcohol does not affect the way the medication works. However, drinking alcohol with Celebrex may increase the risk of certain side effects, such as:

  • indigestion
  • nausea
  • diarrhea
  • headache
  • dizziness
  • serious digestive problems, such as ulcers, bleeding, or perforations (tears) in your digestive system*

If you consume alcohol, talk with your doctor about how much, if any, is safe for you while taking Celebrex.

* Celebrex has a boxed warning for this side effect. A boxed warning is the most serious warning from the Food and Drug Administration (FDA). To learn more, see “Boxed warnings” above.

Before you start treatment with Celebrex, tell your doctor and pharmacist which prescription, over-the-counter, and other medications you take. By sharing this information with them, you may help prevent possible interactions.

If you have questions about drug interactions that may affect you, ask your doctor or pharmacist.

Here’s a closer look at certain drug interactions of Celebrex.

Nonsteroidal anti-inflammatory drugs (NSAIDs)

NSAIDs are drugs that reduce inflammation and relieve pain. Celebrex is a type of NSAID.

Interaction result. Taking Celebrex with another NSAID can increase the risk of serious digestive problems.* These problems include ulcers (sores), bleeding, or perforations (tears) in the lining of your esophagus, stomach, or intestine. These side effects can sometimes be fatal.

Interaction explained. All NSAIDs can increase the risk of serious digestive problems. Taking more than one NSAID at the same time can further increase this risk.

Examples of NSAIDs. Here are some NSAIDs:

Steps you or your doctor may take. Due to this interaction, doctors typically will not prescribe Celebrex with other NSAIDs. You should not take over-the-counter (OTC) medications that contain NSAIDs with Celebrex either. Certain OTC pain relievers and cold, flu, and allergy medications may contain NSAIDs.

It’s important to check with your doctor or pharmacist before taking any other medications with Celebrex. However, in general, you should not take NSAIDs or products containing NSAIDs in combination with Celebrex.

* Celebrex has a boxed warning for this side effect. A boxed warning is the most serious warning from the Food and Drug Administration (FDA). To learn more, see “Boxed warnings” above.

Blood thinners

Blood thinners are drugs used to help prevent and treat dangerous blood clots.

Interaction result. Taking Celebrex with a blood thinner can increase the risk of serious bleeding, including bleeding in your digestive system.*

Interaction explained. Blood thinners make your blood less able to form clots, so you may bleed more easily. Celebrex can also have this effect on your blood. In addition, the drug may cause serious digestive problems, including bleeding in the lining of your esophagus, stomach, or intestine.

If you take Celebrex with a blood thinner, you may be more likely to have bleeding in your digestive system. Also, any bleeding may take longer than usual to stop, so you may have an increased risk of life threatening bleeding.

Examples of blood thinner drugs. Here are some blood thinner medications:

Steps you or your doctor may take. If you take a blood thinner, talk with your doctor about whether Celebrex is right for you. If they prescribe Celebrex, see your doctor right away if you have any symptoms of bleeding in your digestive system. These may include vomiting blood or a substance that looks like coffee grounds. The symptoms can also include passing bloody, black, or tar-like stools.

* Celebrex has a boxed warning for this side effect. A boxed warning is the most serious warning from the Food and Drug Administration (FDA). To learn more, see “Boxed warnings” above.
† Coumadin, a brand-name version of warfarin, used to be available but has been discontinued.

High blood pressure medications

Medications from several different drug classes may be used to treat high blood pressure.

Interaction result. Taking Celebrex with a high blood pressure medication can make the medication less effective at managing high blood pressure. This could increase your risk of serious cardiovascular problems* with Celebrex, such as heart attack and stroke. Also, taking Celebrex with high blood pressure medications can increase your risk of kidney problems.

Interaction explained. Celebrex may increase your blood pressure. This could mean that higher doses of blood pressure medications are needed to manage your blood pressure. Celebrex may also increase your risk of kidney problems. Since high blood pressure medications can also affect your kidneys, taking Celebrex with one of these blood pressure drugs may further increase your risk of kidney problems.

Examples of high blood pressure medications. Here are some drugs used to treat high blood pressure:

Steps you or your doctor may take. If you take medication for high blood pressure, talk with your doctor about whether Celebrex is right for you. If they prescribe Celebrex, your doctor will likely monitor your blood pressure. If it rises, they may increase your dosage of blood pressure medication. Or they may prescribe additional drugs to help manage your blood pressure. In some cases, your doctor may have you stop taking Celebrex.

If you take Celebrex with an ACE inhibitor, an angiotensin II blocker, or a diuretic, your doctor may also monitor your kidney function. Be sure to drink enough fluids if you take this combination of medications. If you become dehydrated, that can increase your risk of kidney problems.

* Celebrex has a boxed warning for this side effect. A boxed warning is the most serious warning from the Food and Drug Administration (FDA). To learn more, see “Boxed warnings” above.
