Diclofenac is a non-steroidal anti-inflammatory drug (NSAID) used in the treatment of pain from arthritis and joint inflammation. According to the National Institutes of Health, up to 20 percent of Diclofenac users will experience some side effect over the course of treatment. While most of these effects are mild, it is important to keep more severe, dangerous effects in mind while using Diclofenac.
Severe Allergic Reactions
Anaphylactic reactions to Diclofenac are rare but have been reported. This severe allergic response is very dangerous. If you or someone you know experiences symptoms of anaphylactic shock while using Diclofenac, seek emergency help immediately. Signs of anaphylactic reactions include reddening or swelling of the skin and eyes, runaway pulse, gasping for breath and fainting.
Cardiac Dangers
In rare instances, Diclofenac can have dangerous effects on the heart and cardiovascular system. Contact your doctor if you experience rapid heart beat, chest pains, shortness of breath or flushing of the skin in response to Diclofenac.
Skin Danger Signs
Many danger signs of reactions to Diclofenac involve skin responses. According to the Mayo Clinic and the National Institutes of Health, skin-based signs of adverse reactions to Diclofenac include loosening of the skin, discoloring of the skin and hives. If you experience any unusual skin reactions to Diclofenac, contact your health professional.
Liver Toxicity
Acute hepatotoxicity and liver failure have also been reported in rare instances with Diclofenac use. Unfortunately, there are no obvious warning signs of liver failure. Let your doctor know if you or your family has a history of liver problems before using Diclofenac. If your doctor places you on a long-term prescription for Diclofenac, she may monitor your liver function over time to ensure that the drug is not damaging your liver.
Stomach Dangers
Many users of Diclofenac experience mild, harmless GI effects such as bloating and excess gas. More dangerous effects on the stomach are also common and include intestinal bleeding, bloody or tar-like stool, abdominal pain, peptic ulcers and decreased urination. These can be signs of serious side effects and should be brought to the attention of your doctor right away.
