What is diclofenac sodium used for?

Diclofenac sodium is a nonsteroidal anti-inflammatory drug (NSAID). It’s used to relieve pain and reduce inflammation. Common uses include:

- Arthritis symptoms (osteoarthritis, rheumatoid arthritis, ankylosing spondylitis)
- Short-term relief of acute musculoskeletal pain from injuries (sprains, strains) or after procedures
- Dental pain and other postoperative pain
- Menstrual cramps (dysmenorrhea)

Notes:
- It works by blocking enzymes that make prostaglandins, which drive inflammation and pain.
- Safety considerations: may cause stomach upset, ulcers, bleeding; can affect kidneys and liver; may increase cardiovascular risk with long-term use; can interact with other meds (anticoagulants, steroids, certain antidepressants). Take with food if advised and use the lowest effective dose for the shortest duration.
- Formulations matter (oral tablets, enteric-coated, topical gels, etc.) and some salts (diclofenac potassium) can have faster onset.

If you’re taking it or considering it, tell me your condition, the formulation you’re using (or plan to use), and any other meds or health issues, and I can tailor the info or discuss safety and dosing.
