Celebrex Adverse Effects
Stomach problems may be more likely to occur if you drink alcoholic beverages while being treated with this medicine. Therefore, do not regularly drink alcoholic beverages while taking this medicine, unless otherwise directed by your doctor.

Taking two or more of the nonsteroidal anti-inflammatory drugs together on a regular basis may increase the chance of unwanted effects. Also, taking acetaminophen, aspirin or other salicylates, or ketorolac (e.g., Toradol) regularly while you are taking a nonsteroidal anti-inflammatory drug may increase the chance of unwanted effects. The risk will depend on how much of each medicine you take every day, and on how long you take the medicines together. If your health care professional directs you to take these medicines together on a regular basis, follow his or her directions carefully. However, do not take acetaminophen or aspirin or other salicylates together with this medicine for more than a few days, and do not take any ketorolac (e.g., Toradol) while you are taking this medicine, unless your doctor has directed you to do so and is following your progress.

Serious side effects can occur during treatment with this medicine. Sometimes serious side effects can occur without any warning. However, possible warning signs often occur, including swelling of the face, fingers, feet, and/or lower legs; severe stomach pain, black, tarry stools, and/or vomiting of blood or material that looks like coffee grounds; unusual weight gain; and/or skin rash. Also, signs of serious heart problems could occur such as chest pain, tightness in chest, fast or irregular heartbeat, or unusual flushing or warmth of skin. Stop taking this medicine and check with your doctor immediately if you notice any of these warning signs.

Check with your doctor immediately if fever, drowsiness, itching of the skin, tiredness, nausea, or stomach pain occurs; these effects may be the first signs of liver toxicity.

Celebrex may cause a serious type of allergic reaction called anaphylaxis. Although this is rare, it may occur often in patients who are allergic to aspirin, other nonsteroidal anti-inflammatory drugs, or sulfonamide-type drugs. Anaphylaxis requires immediate medical attention. The most serious signs of this reaction are very fast or irregular breathing, gasping for breath, wheezing, or fainting. Other signs may include changes in color of the skin of the face; very fast but irregular heartbeat or pulse; hive-like swellings on the skin; and puffiness or swellings of the eyelids or around the eyes. If these effects occur, get emergency help at once. Ask someone to drive you to the nearest hospital emergency room. If this is not possible, do not try to drive yourself. Call an ambulance, lie down, cover yourself to keep warm, and prop your feet higher than your head. Stay in that position until help arrives.
