Generally speaking, the infusion time of dexamethasone is about 5 to 7 days at most. This is because dexamethasone is a long-acting glucocorticoid drug, which may have some side effects after long-term use, and the drug effect is obvious through intravenous drip, but the relative side effects will also be obvious.
In addition, it should be noted that dexamethasone injection has strict drug contraindications, such as it is forbidden for patients with allergic history to glucocorticoid drugs, and it is generally not suitable for patients with myocardial infarction, hypertension, thrombosis, psychosis, electrolyte imbalance, gastroduodenal ulcer, glaucoma and visceral surgery. Therefore, when considering the use of dexamethasone, we should strictly follow the doctor's instructions to avoid long-term medication, and strictly control the dosage and course of treatment to avoid side effects and unnecessary harm to the body.
