Metamizole sodium application

Metamizole sodium is primarily used to reduce fever but can also treat acute arthritis, headache, rheumatic pain, dental pain, and muscle pain in animals.  It has no significant effect on gastrointestinal motility.  However, due to its tendency to cause adverse reactions, it is not generally the drug of choice and is only used for emergency antipyretic treatment in cases of acute hyperthermia, severe conditions, and when no other effective antipyretic drugs are available.  When using this medication, it is important to avoid combining it with chlorpromazine, barbiturates, or other drugs to prevent sudden drops in body temperature, bleeding, and other adverse reactions.
