Eusemin and Eusypterin are oral short-acting contraceptives, both of which are compounded, and the main active ingredients include drospirenone and ethinyl estradiol, with the difference being the content of ethinyl estradiol contained in the two drugs. The difference is that the two drugs contain different amounts of ethinyl estradiol. Eusemin contains 0.03mg of ethinyl estradiol per tablet, while Eusemin contains 0.02mg of ethinyl estradiol per tablet. There is also a difference in the time window for patients to miss a dose of Eusebio and Eusebio. If a patient misses a dose of Eusebio, it can be made up within 12 hours, and if a patient misses a dose of Eusebio, it can be made up within 24 hours without affecting the contraceptive effect. Therefore, the time window for missed doses of Eusebio is broader and patients are relatively more flexible in their use of the drug. In addition, the symptoms of nausea and other adverse reactions caused by Eusebio are likely to be lower than those of Eusebio.
