Can adults receive intramuscular injections for fever?

Fever generally refers to an elevated body temperature. Whether adults with fever can receive intramuscular injections should be determined based on specific circumstances. If body temperature does not exceed 38.5°C and there are no significant discomforts, intramuscular injection is usually unnecessary. Instead, appropriate rest, increased fluid intake, or physical cooling methods such as warm water sponge baths or applying fever-reducing patches may be sufficient. However, if the fever—caused by a significant viral or bacterial infection stimulating the body's temperature regulation center—exceeds 38.5°C and oral antipyretics are ineffective, intramuscular injection may be considered under a doctor's recommendation.
