Blindly using prolactin on one’s own may result in irregular menstruation, long-term hyperandrogenism and other adverse effects. Prolactin is a hormone secreted by the pituitary gland, which stimulates and maintains the mammary glands to secrete milk. If you follow the doctor’s instructions and use it within the prescribed dosage, there will be no adverse effects, but blindly using it on your own may lead to an increase in the body’s prolactin level, which may result in irregular menstruation, long-term hyperandrogenism, and other adverse effects. Therefore, the consequences of using prolactin have a certain relationship with the dosage used. When prolactin is used for treatment, the use of too large a dose may cause the body to remain in a long-term hyperandrogenic state, which in turn may lead to symptoms such as hirsuteness, obesity, facial acne, and so on, in some people. In addition, when prolactin is too high in a woman’s body, it may also affect her menstruation, manifesting itself as prolonged amenorrhea, scanty menstruation, and other symptoms. When using prolactin treatment, it is necessary to follow the doctor’s instructions, and it is recommended to consult a doctor when abnormal symptoms occur during treatment, such as acne, menstrual disorders, and so on.
