Is Diclofenac Sodium Sustained-Release Tablets a painkiller?

Generally, diclofenac sodium sustained-release tablets are pain-relieving medications and should be taken strictly as prescribed by a physician. The specific analysis is as follows:

Diclofenac sodium sustained-release tablets belong to nonsteroidal anti-inflammatory drugs (NSAIDs) and have anti-inflammatory, analgesic, and antipyretic effects. They are indicated for relieving pain caused by chronic joint conditions such as osteoarthritis, rheumatoid arthritis, gouty arthritis, ankylosing spondylitis, and other spondyloarthropathies. However, diclofenac sodium sustained-release tablets should be avoided in patients who are allergic to diclofenac sodium or other NSAIDs, or those with severe heart failure, active gastrointestinal bleeding, or undergoing coronary artery bypass graft surgery in the perioperative period. Diclofenac sodium can irritate the gastrointestinal tract; therefore, it should not be used in cases of gastrointestinal bleeding to prevent worsening of hemorrhage. Additionally, diclofenac sodium may cause vasoconstriction and impair blood supply to the heart, potentially exacerbating cardiovascular conditions.

It is recommended that diclofenac sodium sustained-release tablets be used under the guidance of a physician. Attention should be paid to the patient's history of allergies, medical history, and concomitant medication use during treatment to ensure both safety and efficacy.
