Cough medicine can be taken during menstruation and there are usually no contraindications to its use. Menstrual flow is mainly the process of menstrual blood flow, and women may be relatively prone to coldness and weakness, and may easily get infected with bacteria and viruses. In case of infection, medication should be administered symptomatically. Most medications, however, do not have a greater relationship with menstrual flow. Unless the medication is related to hormones, such as hormonal medication to adjust menstruation, injectable medication to inhibit ovulation, special gynecological medication, etc., the menstrual cycle should be considered. Usually, some gynecological medications may need to be started at a specific time of menstruation, and usually less often involve inability to use during menstruation. The cough medications include antibiotics, such as cephalosporin and azithromycin, which are mainly commonly used to treat chronic bronchitis, and also include proprietary Chinese medicines, which are also usually relatively safe.
