Diclofenac is in a group of drugs called nonsteroidal anti-inflammatory drugs (NSAIDs). Diclofenac works by reducing hormones that cause inflammation and pain in the body.
Diclofenac is used to treat pain or inflammation caused by arthritis or ankylosing spondylitis.
Diclofenac powder (Cambia) is used to treat a migraine headache attack. Do not use this medication to treat a cluster headache.
Cambia will only treat a headache that has already begun. It will not prevent headaches or reduce the number of attacks.
Diclofenac may also be used for other purposes not listed in this medication guide.
This medicine can increase your risk of life-threatening heart or circulation problems, including heart attack or stroke. This risk will increase the longer you use diclofenac. Do not use this medicine just before or after having heart bypass surgery (also called coronary artery bypass graft, or CABG).
Seek emergency medical help if you have symptoms of heart or circulation problems, such as chest pain, weakness, shortness of breath, slurred speech, or problems with vision or balance.
This medicine can also increase your risk of serious effects on the stomach or intestines, including bleeding or perforation (forming of a hole). These conditions can be fatal and gastrointestinal effects can occur without warning at any time while you are taking diclofenac. Older adults may have an even greater risk of these serious gastrointestinal side effects.
Call your doctor at once if you have symptoms of bleeding in your stomach or intestines. This includes black, bloody, or tarry stools, or coughing up blood or vomit that looks like coffee grounds.Do not use any other over-the-counter cold, allergy, or pain medication without first asking your doctor or pharmacist. Many medicines available over the counter contain aspirin or other medicines similar to diclofenac (such as ibuprofen, ketoprofen, or naproxen). If you take certain products together you may accidentally take too much of this type of medication. Read the label of any other medicine you are using to see if it contains aspirin, ibuprofen, ketoprofen, or naproxen. Do not drink alcohol while taking diclofenac. Alcohol can increase the risk of stomach bleeding caused by diclofenac.
Taking an NSAID can increase your risk of life-threatening heart or circulation problems, including heart attack or stroke. This risk will increase the longer you use an NSAID. Do not use this medicine just before or after having heart bypass surgery (also called coronary artery bypass graft, or CABG).
NSAIDs can also increase your risk of serious effects on the stomach or intestines, including bleeding or perforation (forming of a hole). These conditions can be fatal and gastrointestinal effects can occur without warning at any time while you are taking an NSAID. Older adults may have an even greater risk of these serious gastrointestinal side effects.Do not use this medication if you are allergic to diclofenac, or if you have a history of allergic reaction to aspirin or other NSAIDs.
If you have any of these other conditions, you may need a dose adjustment or special tests to safely take diclofenac:
a history of heart attack, stroke, or blood clot;
heart disease, congestive heart failure, high blood pressure;

If you switch brands of diclofenac, your dose needs may change. Follow your doctor's instructions about how much medicine to take.Do not crush, chew, or break an extended-release tablet. Swallow the pill whole. It is specially made to release medicine slowly in the body. Breaking the pill would cause too much of the drug to be released at one time. Dissolve the diclofenac powder (Cambia) with 1 to 2 ounces of water. Do not use any other type of liquid. Stir this mixture and drink all of it right away. Diclofenac powder works best if you take it on an empty stomach.
