What is Cambia?
Cambia (diclofenac) is a nonsteroidal anti-inflammatory drug (NSAID). Diclofenac works by reducing substances in the body that cause pain and inflammation.
Cambia is used to treat a migraine headache attacks, with or without aura, in adults 18 years of age and older. It is not used to prevent migraine headaches. Do not use Cambia 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.
You should not use Cambia if you have a history of allergic reaction to aspirin or NSAIDs (non-steroidal anti-inflammatory drugs).
Cambia can increase your risk of fatal heart attack or stroke, especially if you use it long term or take high doses, or if you have heart disease. Do not use this medicine just before or after heart bypass surgery (coronary artery bypass graft, or CABG).
Cambia may also cause stomach or intestinal bleeding, which can be fatal. These conditions can occur without warning while you are using diclofenac, especially in older adults.
