The generic names of Yusui and Yusmin are Drospirenone Ethinyl Estradiol Tablets and Drospirenone Ethinyl Estradiol II respectively, and their principles of action and side effects are not very different, so there is no “which one has fewer side effects”.
Drospirenone Ethinyl Estradiol Tablets and Drospirenone Ethinyl Estradiol Tablets II are compound preparations of estrogen and progesterone, both of which regulate hormone levels in the body to achieve contraceptive effects. Side effects such as nausea, vomiting, irregular bleeding and breast tenderness may occur after taking both drugs.
In clinical practice, women are advised not to take contraceptives on a long-term and regular basis to prevent pregnancy, in order to avoid infertility symptoms. If serious side effects occur after taking the pill, prompt medical attention is recommended.
