Dipyrone, also known as metamizole, relieves pain, brings down fever and eases spasm in smooth muscle. It is effective, particularly for colicky pain, but it carries a rare risk of a severe drop in white blood cells, which is why several countries have withdrawn it.

What Dipyrone Is Used For

  • Moderate to severe pain
  • Colicky pain from the kidney, gallbladder or gut
  • High fever not responding to other measures
  • Pain after procedures, on medical advice

Common Side Effects

  • Low blood pressure, particularly with injection
  • Nausea
  • Skin rash
  • Sweating

Precautions

Stop the medicine and get an urgent blood count if you develop fever, sore throat, mouth ulcers or feel suddenly unwell, since these can signal a fall in white cells. It is meant for short courses under medical direction, not for everyday aches, and paracetamol or an anti inflammatory is usually the safer first choice.
