Yuketin is an emergency contraceptive, and one capsule of Yuketin contains 75mg of levonorgestrel, so there is a big difference between one capsule of Yuketin and two capsules of Yuketin. Because women do not take contraception after coitus, if you need to take Yutin to remedy, usually must take two pills, in order to achieve the contraceptive effect. Taking one capsule may cause contraceptive failure due to insufficient levonorgestrel content. Therefore, the difference between one tablet and two tablets of Yutin is actually the difference in the content of levonorgestrel, as well as the difference in contraceptive effect. For women who do not have childbearing requirements, it is often necessary to take two capsules at the same time, or to take one capsule 12 hours after taking one capsule, in order to achieve the contraceptive effect.
