Periods are generally substituted for menstruation. menstruation at age 10 is not recommended for suppressive injections if it is not accompanied by other symptoms such as precocious puberty. The onset of menstruation is most often between the ages of 13 and 14, but may occur as early as 11 or as late as 16 and should be evaluated on a case-by-case basis. The onset of menstruation is not only related to a girl’s own growth and development, but also to genetic factors, geographic location, nutritional status, and psychological and psychiatric factors. A few girls will have their menstrual periods slightly earlier than others, and the onset of menstruation at the age of 10 years old is a normal physiological phenomenon, and does not need to be suppressed by injections. However, some girls will have menstruation at the age of 10 with some other symptoms, such as height exceeding the normal range, premature development of secondary sexual characteristics, such as breast development, genital changes, pubic hair, etc., which is considered to be precocious puberty, and needs to be inhibited by injections. Common inhibitory injections include leuprolide and treprostinil, which can treat precocious puberty. However, there are certain requirements for the use of drugs, and there may be adverse reactions, so if you need to use drugs, you should strictly follow the doctor’s instructions, and should not use drugs casually in order to avoid leading to adverse consequences.
