Diclofenac is associated with several potential side effects, particularly affecting the gastrointestinal system and cardiovascular health.
What are the common side effects of diclofenac?
Common side effects of diclofenac include abdominal pain, nausea, vomiting, diarrhea, indigestion, and headache [1]. Some individuals may also experience dizziness or skin rash [1].
How does diclofenac affect the stomach?
Diclofenac, like other nonsteroidal anti-inflammatory drugs (NSAIDs), can irritate the lining of the stomach, increasing the risk of ulcers, bleeding, and perforation [2]. This risk is higher with prolonged use or in individuals with a history of gastrointestinal problems [2].
Are there serious risks associated with diclofenac?
Serious risks include severe gastrointestinal bleeding, heart attack, stroke, and kidney problems [2][3]. Diclofenac can also cause fluid retention and elevated blood pressure, which can be concerning for individuals with heart conditions [3]. Rare but serious allergic reactions can also occur [1].
What are the concerns about diclofenac and heart health?
Diclofenac use has been linked to an increased risk of heart attack and stroke, particularly in those with existing cardiovascular disease or risk factors [2][3]. The risk appears to be dose-dependent and may be present even with short-term use [3].
How does diclofenac work?
Diclofenac works by blocking enzymes called cyclooxygenase (COX-1 and COX-2) [4]. These enzymes are involved in the production of prostaglandins, which are chemicals that promote inflammation, pain, and fever [4]. By inhibiting COX enzymes, diclofenac reduces the production of prostaglandins, thereby alleviating pain and inflammation [4].
When does diclofenac patent expiry occur?
Information regarding specific diclofenac patent expiry dates can be found on specialized pharmaceutical patent tracking websites [5]. These dates vary depending on the specific formulation and market [5].
What are alternatives to diclofenac for pain relief?
Alternative pain relief options include other NSAIDs such as ibuprofen and naproxen, as well as acetaminophen [6]. Topical diclofenac formulations are also available, which may have fewer systemic side effects [7]. For severe pain, other classes of medications or non-pharmacological treatments may be considered [6].
