You can take Prozac Pills for amenorrhea, but they are not effective for all causes of amenorrhea, mainly for amenorrhea caused by liver stagnation and qi stagnation, because Prozac Pills can regulate the menstruation and nourish the blood, soothe the liver and smooth the qi. The reason for this is that you need to go to the hospital for a comprehensive examination to find out the cause before you can reasonably use the medicine to regulate it. If the amenorrhea is caused by premature ovarian failure, you can use estrogen regulation such as estradiol valerate under the guidance of a doctor, and eat more estrogen-containing foods such as soybeans and black beans, as well as take royal jelly to improve the premature ovarian failure. If the endometrium is infected with tuberculosis causing amenorrhea, anti-tuberculosis drugs such as isoniazid and rifampin can be used.
