Diclofenac
Diclofenac is a non-steroidal anti-inflammatory drug that reduces pain and inflammation. Oral and topical forms differ in systemic exposure but can still contribute to the same NSAID risks. Listed uses include acute musculoskeletal pain, osteoarthritis, rheumatoid arthritis and ankylosing spondylitis.

Key points
- Diclofenac can help selected inflammatory pain but should not be combined with another NSAID without clinical advice.
- Ulcer, cardiovascular, kidney and pregnancy risks require review even when symptoms seem routine.
- Chest pain, vomiting blood, black stools or very low urine output needs urgent care.
Listings are for comparison only. Suitability and supply depend on clinician and pharmacy checks, stock, destination rules and prescription requirements.
Important form differences
Oral and injectable diclofenac expose the whole body. Gels act mainly at the application site but are not risk-free, especially over large areas or alongside another NSAID.
Important safety checks
Ulcer or bleeding history, heart or vascular disease, high blood pressure, kidney disease, dehydration, anticoagulants, NSAID-sensitive asthma and pregnancy require review. Use the lowest necessary exposure for the shortest clinically appropriate period.
When to seek urgent care
Seek urgent help for chest pain, sudden breathlessness, stroke signs, vomiting blood, black or bloody stools, severe abdominal pain, facial swelling, breathing difficulty or very low urine output.
