Benefits of Aceclofenac
Relief of pain and inflammation: Aceclofenac 100mg Tablet lowers the level of prostaglandins, the chemical messengers responsible for pain, swelling and stiffness at the site of injury or inflammation, improving joint movement and day-to-day comfort.
Side effects of Aceclofenac
Common side effects include indigestion, stomach pain, nausea, diarrhoea and dizziness. Taking the tablet with food reduces stomach upset.
- Stop the medicine and seek help for black or bloody stools, vomiting blood, severe stomach pain, swelling of the face, wheezing, or a marked fall in urine output.
- Long-term or high-dose NSAID use can affect the stomach, kidneys, heart and blood pressure — use the lowest effective dose for the shortest time.
How to use Aceclofenac
- Take it exactly as prescribed, usually one tablet twice a day.
- Take it with or immediately after food to protect the stomach.
- Swallow the tablet whole with water; do not chew or crush it.
- Do not take other NSAIDs (including over-the-counter ibuprofen or aspirin for pain) at the same time.
How Aceclofenac works
Aceclofenac 100mg Tablet blocks cyclo-oxygenase (COX) enzymes, reducing the production of prostaglandins — the substances that cause pain, swelling and inflammation at injured or inflamed sites.
What if you miss or exceed a dose?
If you miss a dose
Take the missed dose as soon as you remember. If it is nearly time for the next dose, skip the missed one — never double the dose.
In case of overdose
Overdose may cause nausea, vomiting, stomach pain, drowsiness or, rarely, gastrointestinal bleeding and kidney problems. Seek medical attention promptly if an overdose is suspected.
Safety advice
Avoid alcohol; it increases the risk of stomach bleeding with NSAIDs.
Not recommended, especially in the third trimester, as it may harm the developing baby and delay labour.
Use only if a doctor considers it necessary; safer alternatives are usually preferred.
May cause dizziness or drowsiness in some people; avoid driving until you know how it affects you.
NSAIDs can reduce kidney blood flow; use with caution and avoid in significant kidney disease.
Use with caution in liver disease; your doctor may monitor liver function during longer courses.

Should I take Aceclofenac 100mg Tablet on an empty stomach?
No. Always take it with or just after food to reduce the risk of stomach irritation and ulcers.
Can I take Aceclofenac 100mg Tablet for a headache?
It is intended for inflammatory and musculoskeletal pain and should be used only when prescribed — simple headaches are usually managed with paracetamol.
