If you miss a dose of Eusemide on the first day of the first week, be sure to add additional pills to make up for it. Eusemin, also known as drospirenone ethinyl estradiol tablets, is a short-acting contraceptive containing the unique progestin drospirenone, which is one of the short-acting avoidance pills commonly used by women in clinical practice. The product is a compound preparation with the appearance of a yellowish film-coated tablet, which appears white after removal of the coating, and is usually administered orally. If you forget to take the medicine within twelve hours, the contraceptive protection will not be reduced. Once you remember the missed dose, you must take it immediately, and the next medicine should be taken within the specified time, which will not affect the effect of contraception.
