Aceclofenac is an anti-inflammatory pain reliever . These types of painkillers are also called NSAIDs . It has an analgesic, anti-inflammatory and fever-reducing effect.
Doctors prescribe it for rheumatoid arthritis, Bechterew’s disease and osteoarthritis .
- Rheumatoid arthritis is inflammation of the joints. It causes pain, stiffness and swelling in the joints of, for example, hands, wrists, ankles or feet. Usually the symptoms are present in the same joints on the left and right.
- The inflammation makes the joint thick and tender, sometimes warm. Over time, the joints get damaged.
- As soon as it is clear that rheumatoid arthritis is present, the doctor prescribes special medicines, the DMARDs. These drugs counteract the cause of the joint inflammation.
- The effect of a DMARD is not immediately noticeable, but only after a few weeks. In the meantime, the doctor can prescribe aceclofenac for the inflammation and pain. Also later, while using a DMARD, you can temporarily or occasionally use aceclofenac for pain.

- This drug inhibits inflammation, reducing redness, swelling and pain.
- The analgesic effect starts within three hours. This effect lasts for about twelve hours. The redness and swelling will subside after a few days to a week.
- Bechterew’s disease (ankylosing spondylitis) is an inflammation of the joints of the pelvis and spine. It’s a rheumatic disease.
- With Bechterew’s disease you suffer from pain and stiffness in the lower back. Especially in the morning after getting up or after sitting for some time. The pain disappears through movement. Fatigue can cause the pain to reappear during the day.

- The effect of sulfasalazine is not immediately noticeable, but only after a few weeks. In the meantime, the doctor can prescribe aceclofenac for the inflammation and pain.
- This drug inhibits inflammation, reducing redness, swelling and pain.
- The analgesic effect of aceclofenac starts within three hours. This effect lasts for about twelve hours. The redness and swelling will subside after a few days to a week.

- The complaints can be reduced by moving the painful joint and by training the muscles. But do not overload the joint.
- Paracetamol is the best choice for pain. This has the fewest side effects and usually works as well as aceclofenac. If paracetamol is not effective after two weeks, the doctor can also prescribe aceclofenac.
