If the infusion uses ordinary drugs, it will not affect menstruation, but if the infusion contains hormonal drugs, it will easily affect menstruation. If there is blood-boosting or cold medicine, it will easily affect menstruation and cause symptoms such as increased menstrual flow and prolonged periods. If there is prolonged periods for more than 10 days, you need to go to the obstetrics and gynecology department of the hospital in time and cooperate with the doctor to use hemostatic drugs, such as uterine hemorrhage. If the input of electrolytes or energy drugs will not affect the menstruation, there is no need to worry too much. During menstruation, it is necessary to pay attention to rest and avoid straining. At the same time, it is necessary to keep the small abdomen warm and avoid cold to avoid stagnation of menstrual blood and symptoms such as dysmenorrhea. It is best to drink brown sugar and ginger water after the infusion during menstruation to avoid the body from getting cold, and the infusion should not be too fast.
