Diclofenac: The Pain Reliever & It’s Association With Sexual Health
Diclofenac is a widely-used, nonsteroidal anti-inflammatory drug (NSAID) that has been helping millions of people around the world to manage pain and inflammation for decades. In this comprehensive guide, we’ll delve into the science behind diclofenac, its various formulations, potential side effects, and frequently asked questions to provide you with a complete understanding of this powerful medication.
What is Diclofenac?
Diclofenac is a nonsteroidal anti-inflammatory drug (NSAID) that is used to reduce inflammation and pain in conditions such as arthritis, acute injury, and menstrual cramps. It is sold under various brand names including Voltaren, Cataflam, and Zipsor.
Diclofenac works by inhibiting the activity of cyclooxygenase (COX) enzymes, which are responsible for producing prostaglandins. Prostaglandins are hormone-like substances that are involved in inflammation, pain, and fever. By blocking the production of prostaglandins, diclofenac reduces inflammation, pain, and fever.
Diclofenac is available in different forms, including tablets, capsules, injections, topical gels, and patches. The dose and route of administration depend on the condition being treated and the patient’s individual needs.
Diclofenac may cause side effects, such as stomach upset, headache, dizziness, and rash. It can also increase the risk of serious cardiovascular events, such as heart attack and stroke, especially when used at high doses or for long periods of time. Diclofenac also poses the risk of severe life threatening allergic reactions in rare cases known as anaphylaxis. Therefore, it is important to use diclofenac only as directed by a healthcare provider and to report any unusual symptoms promptly.
Diclofenac is a prescription medication and should only be used under the supervision of a qualified healthcare professional. It is not recommended for use during pregnancy or while breastfeeding.
How Does Diclofenac Work?
There are two types of COX enzymes: COX-1 and COX-2. COX-1 is involved in the production of prostaglandins that are involved in normal physiological processes, such as the protection of the stomach lining and the regulation of blood flow to the kidneys. COX-2, on the other hand, is involved in the production of prostaglandins that are involved in inflammation, pain, and fever.
Diclofenac inhibits the activity of both COX-1 and COX-2 enzymes, although it has a greater affinity for COX-2. By inhibiting the activity of these enzymes, diclofenac reduces the production of prostaglandins, which leads to a reduction in inflammation, pain, and fever.
Diclofenac is absorbed into the bloodstream and distributed throughout the body, where it reaches the sites of inflammation and pain. It is metabolized in the liver and excreted in the urine and feces.

There are also some precautions to consider when taking diclofenac. People with a history of stomach ulcers or bleeding, kidney disease, liver disease, or heart disease should use caution when taking diclofenac. It is also important to avoid taking diclofenac with other NSAIDs, including aspirin, as this can increase the risk of side effects. Additionally, diclofenac can interact with certain medications, such as blood thinners and diuretics.
If you are pregnant or breastfeeding, you should talk to your doctor before taking diclofenac. It is also important to tell your doctor about all medications, supplements, and herbal remedies you are taking before starting treatment with diclofenac.
Diclofenac, like any other medication, can interact with other drugs, which may alter its effectiveness or increase the risk of side effects. Some of the significant drug interactions of diclofenac include:
Aspirin and other NSAIDs: The concurrent use of aspirin or other NSAIDs with diclofenac can increase the risk of gastrointestinal bleeding and ulcers.
Blood thinners: Diclofenac may interact with blood-thinning medications such as warfarin, increasing the risk of bleeding.
ACE inhibitors and diuretics: Concurrent use of diclofenac with ACE inhibitors or diuretics can lead to decreased kidney function or acute kidney failure.
Corticosteroids: Combining diclofenac with corticosteroids may increase the risk of gastrointestinal bleeding and ulcers.
Lithium: Diclofenac may increase the blood levels of lithium, increasing the risk of lithium toxicity.
Methotrexate: Diclofenac may increase the blood levels of methotrexate, increasing the risk of methotrexate toxicity.
Cyclosporine: Concurrent use of diclofenac with cyclosporine can increase the risk of kidney damage.
Digoxin: Diclofenac may increase the blood levels of digoxin, increasing the risk of digoxin toxicity.
It is important to talk to your healthcare provider about all the medications, supplements, and herbal products you are taking before starting treatment with diclofenac.

Additionally, it is essential to report any unusual symptoms or side effects while taking diclofenac to your healthcare provider immediately.
Diclofenac & Health Conditions
While diclofenac is generally safe and effective for most people, it may have some side effects, including an increased risk of high blood pressure (hypertension).
Studies have shown that diclofenac can cause an increase in blood pressure in some people, especially those with pre-existing high blood pressure or cardiovascular disease. This increase in blood pressure can be mild to moderate, but in some cases, it can be severe and lead to complications such as heart attacks, strokes, or kidney damage.
Therefore, it is important to talk to your doctor before taking diclofenac, especially if you have a history of high blood pressure or cardiovascular disease. Your doctor may monitor your blood pressure while you are taking the medication and adjust the dosage or prescribe an alternative medication if necessary.
If you experience symptoms such as headache, dizziness, blurred vision, or chest pain while taking diclofenac, seek medical attention immediately. These symptoms could be signs of a more severe increase in blood pressure.
While diclofenac can be effective in relieving pain and inflammation, it may have some negative effects on heart health. Studies have shown that diclofenac can increase the risk of heart attacks, stroke, and other cardiovascular events, especially in people with pre-existing heart conditions or risk factors for heart disease.
The exact mechanism by which diclofenac affects the heart is not fully understood, but it is thought to be related to the medication’s ability to inhibit the production of prostaglandins, which are substances that play a role in regulating blood flow and protecting the heart.
Therefore, it is important to talk to your doctor before taking diclofenac if you have a history of heart disease, high blood pressure, or other cardiovascular risk factors such as smoking, high cholesterol, or diabetes. Your doctor may monitor your heart health while you are taking the medication and adjust the dosage or prescribe an alternative medication if necessary.
If you experience symptoms such as chest pain, shortness of breath, or dizziness while taking diclofenac, seek medical attention immediately. These symptoms could be signs of a more severe cardiovascular event.
