Eusel, generic name Drospirenone Ethinylestradiol Tablets (II), is a compounded short-acting contraceptive. Its clinical indications are: 1. oral contraceptives for women. 2. moderate acne vulgaris for primiparous women older than 14 years of age who have no known contraindications to oral contraceptives. It is generally desired to use this product to treat acne when oral contraceptives are used as a contraceptive measure. To take it, start taking it on the 1st day of the menstrual cycle, or the 1st Sunday after the start of the menstrual cycle, and take 1 tablet by mouth at the same time every day. You should not miss a dose in between. If you miss a dose, you need to make up for it as soon as possible within 12 hours. Otherwise, it may cause irregular bleeding and affect the effectiveness of contraception.
