What is diclofenac?

Diclofenac is a non‑steroidal anti‑inflammatory drug (NSAID) used to relieve pain, reduce inflammation, and lower fever. It’s commonly found in both prescription and over‑the‑counter formulations, most often as a topical gel, patch, or oral tablet.

Key points

Quick FAQ

• Is diclofenac safe for everyone?
  No. People with a history of ulcers, heart disease, kidney problems, or severe liver disease should avoid it or use under strict medical supervision.

• Can it be used during pregnancy?
  Generally, diclofenac is avoided in the third trimester because of the risk of premature closure of the ductus arteriosus in the fetus. Use only if a doctor deems the benefit outweighs the risk.

• How long can I take it?
  Short‑term use (days to a few weeks) is typical. Long‑term use should be monitored by a healthcare provider to watch for GI, kidney, or cardiovascular complications.

• What’s the difference between oral and topical diclofenac?
  Oral tablets are systemic, affecting the whole body, while topical formulations deliver the drug directly to a specific area, generally producing fewer systemic side effects.

Bottom line: Diclofenac is a versatile NSAID for pain and inflammation, but it must be used with caution, especially if you have underlying health conditions or are on other medications. Always follow your prescribing information or a healthcare professional’s guidance.
