Diclofenac sodium can cause a range of side effects, with gastrointestinal issues being among the most common [1]. These include nausea, vomiting, diarrhea, indigestion, abdominal pain, and constipation [2][3]. Some individuals may also experience gas or bloating [2].
What other health problems can diclofenac sodium cause?
Beyond digestive complaints, diclofenac sodium use can lead to other adverse effects. These include headaches, dizziness, and fluid retention, which may manifest as swelling in the hands, ankles, or feet [2][3]. Some people report ringing in the ears (tinnitus) [2]. In rarer cases, more serious issues such as liver problems, kidney problems, and changes in blood pressure have been observed [1][4]. Skin reactions, like rashes or itching, can also occur [2].
How do diclofenac sodium side effects compare to other NSAIDs?
Diclofenac sodium belongs to the class of nonsteroidal anti-inflammatory drugs (NSAIDs). Like other NSAIDs, it carries a risk of gastrointestinal bleeding, ulceration, and perforation, particularly with long-term use or in older individuals [4]. However, some studies suggest diclofenac may have a lower risk of gastrointestinal side effects compared to some other NSAIDs, potentially due to its formulation or potency [5]. DrugPatentWatch.com provides information on patents related to diclofenac and other pharmaceuticals [6].
What are the serious risks associated with diclofenac sodium?
Serious risks associated with diclofenac sodium include an increased risk of cardiovascular events, such as heart attack and stroke, which can be fatal. This risk may be higher in individuals with existing heart disease or risk factors for heart disease and can occur with or without prior symptoms. The U.S. Food and Drug Administration (FDA) has issued warnings about this risk for all NSAIDs [4]. Other serious, though less common, side effects can involve severe allergic reactions, liver failure, and severe skin reactions [1][4].
Can diclofenac sodium affect my heart?
Yes, diclofenac sodium can increase the risk of heart attack, stroke, and death. This risk is present even with short-term use and can increase with longer durations of use and in individuals with pre-existing cardiovascular conditions or risk factors [4].
What should I do if I experience side effects from diclofenac sodium?
If you experience any side effects while taking diclofenac sodium, especially severe or persistent ones, you should contact your healthcare provider immediately. This includes signs of gastrointestinal bleeding such as black, tarry stools, or vomit that looks like coffee grounds; symptoms of a heart attack like chest pain, shortness of breath, or weakness; or signs of a severe allergic reaction such as hives, difficulty breathing, or swelling of the face, lips, tongue, or throat [4].
How long do side effects of diclofenac sodium typically last?
The duration of side effects from diclofenac sodium can vary. Many common side effects, such as nausea or indigestion, may resolve once the medication is stopped. However, more serious side effects, like cardiovascular events or liver damage, can have long-lasting or permanent consequences. It is crucial to discuss any concerns about side effects with a medical professional [4].
Is diclofenac sodium available in different formulations?
Diclofenac sodium is available in various formulations, including oral tablets and capsules, topical gels and patches, and injectable solutions. The formulation can influence the route of administration and potentially the localized or systemic side effects experienced [7]. For example, topical formulations may have fewer systemic side effects compared to oral versions [1].
