This medication is a nonsteroidal anti-inflammatory drug (NSAID), specifically a COX-2 inhibitor, which relieves pain and swelling (inflammation). It is used to treat arthritis, acute pain, and menstrual pain and discomfort. The pain and swelling relief provided by this medication helps you perform more of your normal daily activities.

If you are treating a chronic condition such as arthritis, ask your doctor about non-drug treatments and/or using other medications to treat your pain. See also Warning section.

This drug works by blocking the enzyme in your body that makes prostaglandins. Decreasing prostaglandins helps to reduce pain and swelling.

This section contains uses of this drug that are not listed in the approved professional labeling for the drug but that may be prescribed by your health care professional. Use this drug for a condition that is listed in this section only if it has been so prescribed by your health care professional.

This drug may also be used for gout attacks.

Read the Medication Guide provided by your pharmacist before you start using celecoxib and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

Before taking celecoxib, tell your doctor or pharmacist if you are allergic to it; or to aspirin, other NSAIDs (such as ibuprofen), other COX-2 inhibitors; or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details.

Before using this medication, tell your doctor or pharmacist your medical history, especially of:

• asthma (including a history of worsening breathing after taking aspirin or other NSAIDs)
• liver disease
• stomach/intestine/esophagus problems (such as bleeding, ulcers, recurring heartburn)
• heart disease (such as angina, heart attack)
• high blood pressure
• stroke
• blood disorders (such as anemia, bleeding/clotting problems)
• growths in the nose (nasal polyps)

Kidney problems can sometimes occur with the use of NSAID medications, including celecoxib. Problems are more likely to occur if you are dehydrated, have heart failure or kidney disease, are an older adult, or if you take certain medications (see also Drug Interactions section). Drink plenty of fluids as directed by your doctor to prevent dehydration and tell your doctor right away if you have a change in the amount of urine.

This medicine may cause stomach bleeding. Daily use of alcohol and tobacco, especially when combined with this medicine, may increase your risk for stomach bleeding. Limit alcohol and smoking. Consult your doctor or pharmacist for more information.

Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).

Older adults may be at greater risk for stomach/intestinal bleeding, kidney problems, heart attack, and stroke while using this drug.

Caution is advised when using this drug for children with a certain type of arthritis (systemic onset juvenile rheumatoid arthritis) because they may be at increased risk for a very serious bleeding/clotting problem (disseminated intravascular coagulation). Get medical help right away if your child develops sudden bleeding/bruising or bluish skin in the fingers/toes.

Before using this medication, women of childbearing age should talk with their doctor(s) about the benefits and risks. Tell your doctor if you are pregnant or if you plan to become pregnant. This medication may harm an unborn baby and cause problems with normal labor/delivery. It is not recommended for use in pregnancy from 20 weeks until delivery. If your doctor decides that you need to use this medication between 20 and 30 weeks of pregnancy, you should use the lowest effective dose for the shortest possible time. You should not use this medication after 30 weeks of pregnancy.

This medication passes into breast milk. Consult your doctor before breastfeeding.

Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions. Keep a list of all the products you use (including prescription/nonprescription drugs and herbal products) and share it with your doctor and pharmacist. Do not start, stop, or change the dosage of any medicines without your doctor's approval.

Some products that may interact with this drug include:

• aliskiren
• ACE inhibitors (such as captopril, lisinopril)
• angiotensin II receptor blockers (such as valsartan, losartan)
• cidofovir
• lithium
• "water pills" (diuretics such as furosemide)

This medication may increase the risk of bleeding when taken with other drugs that also may cause bleeding. Examples include anti-platelet drugs such as clopidogrel, "blood thinners" such as dabigatran/enoxaparin/warfarin, among others.

Check all prescription and nonprescription medicine labels carefully since many medications contain pain relievers/fever reducers (aspirin, NSAIDs such as naproxen or ibuprofen). These drugs are similar to celecoxib and may increase your risk of side effects if taken together. However, if your doctor has told you to take low-dose aspirin to prevent heart attack or stroke (usually 81-162 milligrams a day), you should keep taking the aspirin unless your doctor tells you not to. Ask your doctor or pharmacist for more details.
