Intramuscular injections are useful for colds, but only if the fever does not go down or if there is a serious bacterial infection. Most colds are caused by viral infections, which have a certain degree of self-healing, usually lasting about a week. Clinical treatment of colds mostly takes oral medication, such as Lianhua Qingdian capsule, which is convenient and safe to administer. However, if the fever does not go down or if there is a secondary bacterial infection, the physician may weigh the pros and cons of intramuscular injections, such as intramuscular injections of compound aminobarbital, ceftriaxone sodium, and other drugs. If the cold is only mild, usually no medication is needed, you can drink plenty of water, pay attention to rest for a week or so can recover; if it is a serious cold can be treated by appropriate oral medication, the more serious condition can also choose to intramuscular injection to treat. Colds need to go to the hospital, under the guidance of the doctor to use the correct drugs and methods of treatment, not indiscriminate use of drugs.
