Aminoglutethimide is the trade name of the drug called compound aminobarbital injection, usually 2ml a piece. It is used clinically for intramuscular injection in case of fever and is very effective in reducing fever. About 10 minutes after the intramuscular injection of Aminoglutethimide, the patient’s body will sweat, and then the temperature will drop. For severe pneumonia, aspiration pneumonia, urinary tract infections and other fevers with heavy symptoms and foci of infection, the use of Advil is only a temporary solution to the problem of reducing fever, and the temperature will rise again as soon as the effect of the drug wears off. For fever after a mild cold, the effect of intramuscular injection of Advil is very good, and at the same time, we should pay attention to drinking more hot water and replenishing fluids. For fever caused by respiratory, urinary tract or other foci of infection, active treatment of the primary lesion is still needed.
