Yutin belongs to the emergency contraceptive pill, and Yutin a capsule contains levonorgestrel is 75mg, so Yutin a capsule and two capsules have a big difference. Because women do not take contraceptive measures after intercourse, if you need to take yutin to remedy, generally must take two capsules to achieve the contraceptive effect. And take a capsule because the content of levonorgestrel is not enough, may cause contraceptive failure. Therefore, the difference between one and two capsules of Yutin is actually the difference in the content of levonorgestrel, as well as the difference in the effectiveness of contraception. For women without childbearing requirements, they often need to take two capsules at the same time, or take one capsule after 12 hours of taking one capsule, in order to achieve the contraceptive effect.
