Side Effects of Diclofenac Potassium
Common diclofenac potassium side effects may include abdominal pain (or stomach pain), heartburn or indigestion, dizziness, and gas. Some people may also experience more serious side effects that can be a sign of heart attack or stroke, such as chest pain, slurred speech, and weakness on one part of the body. If you develop any of these serious side effects, be sure to seek medical attention immediately.
As with any medicine, there are possible side effects with diclofenac potassium (Cambia™, Cataflam®, Zipsor™). However, not everyone who takes the medicine will experience side effects. In fact, most people tolerate it well. When people do develop diclofenac potassium side effects, in many cases they are minor, meaning they require no treatment or are easily treated by you or your healthcare provider.
(The side effects discussed below are not a complete list of side effects reported with diclofenac potassium. Your healthcare provider can discuss a more complete list of side effects with you.)
Serious Diclofenac Potassium Side Effects
As with any drug, there is the potential for serious side effects with diclofenac potassium. The U.S. Food and Drug Administration (FDA) warns that people using NSAIDs, including diclofenac potassium, may have a higher risk of having a heart attack or stroke than those people who do not take NSAIDs. This warning does not apply to those who take aspirin. This risk may be higher in people who have been taking NSAIDs for a long time.
These events can occur without any warning and can lead to loss of life. Get emergency medical help by calling 911 as soon as possible if you experience any of the following symptoms:
