Diclofenac is a nonsteroidal anti-inflammatory drug (NSAID) that is commonly used to relieve pain and inflammation. However, recent studies have linked the use of diclofenac to an increased risk of heart problems, including heart attack and stroke. This has led to concerns among healthcare professionals and patients alike about the safety of diclofenac.
Diclofenac works by blocking the production of prostaglandins, which are chemicals that cause pain and inflammation. While this can be an effective way to relieve pain, it can also have negative effects on the cardiovascular system. Prostaglandins play an important role in regulating blood flow and preventing blood clots, so blocking their production can increase the risk of heart problems.
Despite these concerns, diclofenac is still widely used and prescribed by healthcare professionals. This has led to calls for greater awareness among patients and healthcare professionals about the potential risks of diclofenac, as well as the need for alternative pain relief options.
Key Takeaways

Overview of Diclofenac and Cardiovascular Risks
Diclofenac and NSAIDs
Diclofenac is a non-steroidal anti-inflammatory drug (NSAID) that is commonly used to relieve pain and inflammation. NSAIDs work by blocking the production of prostaglandins, which are hormone-like substances that cause pain and inflammation. Diclofenac is a potent inhibitor of both cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2), which are enzymes involved in the production of prostaglandins.
NSAIDs, including diclofenac, are widely used for the treatment of various conditions, such as arthritis, musculoskeletal pain, and fever. However, the use of NSAIDs has been associated with an increased risk of cardiovascular events, such as heart attack and stroke. The risk of cardiovascular events may vary depending on the type of NSAID used, the dose, and the duration of use.
Mechanisms of Cardiovascular Risks
The mechanisms by which NSAIDs, including diclofenac, increase the risk of cardiovascular events are not fully understood. However, it is believed that NSAIDs may increase the risk of cardiovascular events by several mechanisms.
Firstly, NSAIDs may increase blood pressure by reducing the production of prostaglandins, which are involved in the regulation of blood pressure. Secondly, NSAIDs may increase the risk of blood clots by inhibiting the production of prostacyclin, which is a prostaglandin that helps to prevent blood clots. Thirdly, NSAIDs may increase the risk of heart attack and stroke by increasing the production of thromboxane, which is a substance that promotes blood clotting.
Diclofenac has been shown to pose a cardiovascular health risk compared with non-use, paracetamol use, and use of other traditional NSAIDs. The dose dependency of the adverse effects of diclofenac remains poorly understood. Although the relative risk of major adverse cardiovascular events was highest in individuals with low or moderate baseline risk (that is, diabetes mellitus), the absolute risk was highest.
It is important to note that the cardiovascular risks associated with NSAIDs, including diclofenac, may vary depending on individual factors, such as age, sex, medical history, and other medications being taken. Therefore, it is important to consult a healthcare professional before taking NSAIDs, especially if you have a history of cardiovascular disease or other medical conditions.
Clinical Evidence and Studies
Meta-Analysis and Cohort Studies
Diclofenac use has been associated with an increased risk of cardiovascular events. A meta-analysis of observational studies published in the British Medical Journal found that diclofenac was associated with a significantly increased risk of major vascular events, including myocardial infarction, stroke, and cardiovascular death, compared with non-use, paracetamol use, and use of other traditional non-steroidal anti-inflammatory drugs. The meta-analysis included data from 639,000 individuals from 6 different studies.
Several cohort studies have also been conducted to investigate the association between diclofenac use and cardiovascular risk. A nationwide cohort study in Denmark found that diclofenac initiators had an upper gastrointestinal bleeding risk similar to that of naproxen initiators and more than twice the risk of ibuprofen initiators. Another Danish nationwide cohort study found that diclofenac initiators had a significantly increased risk of cardiovascular events compared with non-use, paracetamol use, and use of other traditional non-steroidal anti-inflammatory drugs.
Incidence and Relative Risks
The incidence rate ratio of cardiovascular events among diclofenac initiators compared with non-use, paracetamol use, and use of other traditional non-steroidal anti-inflammatory drugs was found to be 1.86 (95% confidence interval 1.68 to 2.04) in a study published in the British Medical Journal. The relative risk of myocardial infarction, stroke, or cardiovascular death among diclofenac users compared with non-use, paracetamol use, and use of other traditional non-steroidal anti-inflammatory drugs was 1.63 (95% confidence interval 1.12 to 2.37) in another study.
It is important to note that these studies are observational and do not prove causation. However, the consistent findings across multiple studies suggest a strong association between diclofenac use and cardiovascular risk. Healthcare providers should weigh the benefits and risks of diclofenac use in individual patients, taking into account their cardiovascular risk profile and other medical conditions.
Risk Factors and Patient Considerations
Diclofenac is a widely used nonsteroidal anti-inflammatory drug (NSAID) that has been associated with an increased risk of cardiovascular events. Therefore, it is important to consider the potential risks and benefits of diclofenac treatment for each patient.
High-Risk Populations
Certain populations are at higher risk of developing cardiovascular events when taking diclofenac. These populations include patients with a history of heart attack, heart failure, hypertension, diabetes, and high baseline risk. It is important to carefully consider the risks and benefits of diclofenac treatment in these populations.
Diclofenac Dosage and Duration
The risk of developing cardiovascular events due to diclofenac use increases with the dosage and duration of treatment. Therefore, it is important to use the lowest effective dose for the shortest duration possible. Long-term use of diclofenac should be avoided, especially in patients with a history of kidney disease or arterial thrombotic risk.
Patients should also be advised to promptly report any symptoms of cardiovascular events, such as chest pain, shortness of breath, or weakness. Additionally, patients should be advised to avoid diclofenac use if they have a history of allergic reactions to NSAIDs.
It is important to note that diclofenac is not recommended for use in patients with significant risk factors for cardiovascular events, such as hypertension, hyperlipidaemia, and smoking. Patients with these risk factors should be carefully considered before initiating diclofenac treatment.
In summary, diclofenac should be used with caution in patients at high risk of developing cardiovascular events. It is important to carefully consider the risks and benefits of diclofenac treatment for each patient and to use the lowest effective dose for the shortest duration possible. Patients should be advised to report any symptoms of cardiovascular events and to avoid diclofenac use if they have a history of allergic reactions to NSAIDs.
Management and Prevention
Diclofenac is a popular nonsteroidal anti-inflammatory drug (NSAID) used to relieve pain and inflammation. However, it is important to note that diclofenac use has been associated with an increased risk of cardiovascular events such as heart failure, stroke and heart attack. As such, healthcare professionals are encouraged to be cautious when prescribing this drug, especially to patients with underlying heart conditions.
Alternatives to Diclofenac
When managing pain and inflammation, there are several alternatives to diclofenac that can be considered. Paracetamol is a popular over-the-counter pain reliever that is generally considered safe for most people. Ibuprofen and naproxen are other NSAIDs that can be used as alternatives to diclofenac. However, it is important to note that these drugs also have their own side effects and risks, and should be used with caution.
Aspirin is another NSAID that is commonly used to prevent blood clots and reduce the risk of heart attack and stroke. However, it is important to note that aspirin is not recommended for everyone and should only be taken under medical advice.
