What is Novalgin?
Novalgin belongs to a group of fever-reducing painkillers called NSAIDs and is administered in the form of an injection. The active ingredient in Novalgin is metamizole (metamizol sodium monohydrate). A 5-ml injection contains 2500 mg of metamizol sodium monohydrate; a 2-ml injection contains 1000 mg of metamizol sodium monohydrate. Novalgin injections require a prescription.
What is Novalgin used for?
Novalgin is used in the short-term treatment of high fever and severe, acute pain. Injections are only administered if other treatments have failed to provide relief. Some painkillers should not be used to treat severe or acute pain or fever. In these cases, Novalgin can help.
How to use Novalgin
You should be lying down when the injection is given. Do not inject more than 1 ml per minute. Be sure to monitor blood pressure, heart rate and breathing during administration. Allow the fluid to come to room temperature prior to injecting it. Novalgin may cause a red colouration of the urine. Despite its alarming appearance, this red urine is not serious and will disappear once the treatment is over. The injection fluid should not be mixed with other solutions. Duration of treatment is determined by your doctor. Be sure to follow doctor’s orders exactly.
The appropriate dosage is determined by a doctor and varies per individual. The usual dosage is:
- 2.0 ml 2 x 5 ml or 4 x 2.5 ml: for persons aged 15 years and above
- 0.8 ml 4 x 1.6 ml: for persons aged 13 - 15 years (> 50 kg)
- 0.5 ml 4 x 1.0 ml: for persons aged 9 - 12 years (> 33 kg)
- 0.4 ml 4 x 0.8 ml: for children aged 6 - 8 years (> 24 kg)
- 0.3 ml 4 x 0.6 ml: for children aged 3 - 5 years (> 18 kg)
Like all medicines, Novalgin can have side effects but they are rare. Pain or redness at the injection site or phlebitis at the injection site (vein inflammation) may occur. See the package leaflet for more information on possible side effects.
