Fenbuterol is used to treat menstrual pain. Fenbid has a relatively good antipyretic and analgesic effect and can provide pain relief within a short time after taking it. Therefore, patients who suffer from menstrual pain can take some Fenbid to relieve their symptoms. However, Fenbid is after all an antipyretic and analgesic drug, and it is not recommended to use it for a long time. Patients who suffer from dysmenorrhea should go to the hospital to have a checkup to find the cause. Some cases of dysmenorrhea may be related to uterine fibroids, endometriosis, or uterine lesions, which need to be treated by other methods. In addition, patients with dysmenorrhea must rest well during menstruation, avoid eating cold food and spicy food, and pay attention to the warmth of the small stomach area to avoid getting cold.
