The pill is a hormonal drug, and long-term use of the pill by a 15-year-old patient can have side effects, causing endocrine disruption and infertility, so 15-year-old adolescent patients should take the pill sparingly. Because the pill is a hormonal drug, long-term use may cause endocrine disorders, obesity, irregular and abnormal menstruation, and menstrual disorders, etc. These side effects are still relatively obvious. Therefore, it is not recommended to take a large amount of contraceptive drugs for a long time, but occasional, small amount of use, the impact on the body is not much, and do not worry too much.
