About Diclofenac

Diclofenac belongs to a group of medicines called non-steroidal anti-inflammatory drugs (NSAIDs). This medicine reduces the symptoms of inflammation, such as swelling, redness and fever.

Diclofenac is used to treat:

  • Rheumatic disorders including arthritis and arthrosis, and certain forms of back pain (Bechterew’s disease).
  • Frozen shoulder.
  • Menstrual pain.
  • Pain from surgery or injury.
  • Pain and fever caused by illness.

How to use Diclofenac

Diclofenac is available in various forms, including gastro-resistant tablets and delayed release tablets. The doctor will recommend the right variant for you depending on your symptoms.

Swallow the tablets whole with a drink of water, without chewing. Take the tablets with food. You should take the lowest effective dose of Diclofenac for the shortest possible time.

Dosage

Dosage varies per person and is determined by a doctor for each specific patient depending on the symptoms. The general dosage guidelines are listed below.

Adults (18 years and above):

  • For rheumatic joint pain (arthritis): the starting dose is 150 mg a day, the maintenance dose for long-term treatment is 75-100 mg.
  • For joint wear (arthrosis): the starting dose is 100-150 mg a day, depending on the severity of the pain. The maintenance dose for long-term treatment is 75-100 mg.
  • For frozen shoulder, painful inflammation and swelling, for example after a dental procedure or surgery: the starting dose is 150 mg a day, depending on the severity of the pain.
  • For menstrual pain: dosage is determined by a doctor and typically varies between 50‑150 mg a day. The starting dose is 50-100 mg. A doctor may increase this dose to a maximum daily dose of 200 mg if needed.
  • Illness accompanied by fever: 0.5-1 mg per kg body weight a day.

The daily dose is usually divided in two or three doses. Diclofenac is not suitable for use in children. For people aged 65 and above, the appropriate dose is determined by a doctor.
