Norlevo 1500 and Postinor-2 are both available. The Norlevo product is a single-pill emergency contraceptive, and the Postinor-2 divides that same medication and dose into two pills. If you take both pills at the same time, they are equivalent; neither is better than the other.

Take 2 pills within 72 hours after unprotected sex:

NorLevo 0.75 mg which is Postinor-2

Hello You can take the morning after pill or plan B or the emergency contraception pill to prevent pregnancy from occurring. The morning after pill, plan b or ecp will prevent pregnancy occurring upto 97% so there is still a 3% chance that pregnancy can occur - because of this I would recommend that you perform a pregnancy test 3-4 weeks after taking the morning after pill, plan b or ecp. You must take the morning after pill, plan b or ecp within 72 hours of unprotected intercourse. 72 hours is three days. You must never use birth control in place of emergency contraception as it simply does not work and may cause side effects lasting several days.

theplan b pill which i believe you are talking about will work 12 hours after having sex. if you have sex a couple of times after taking it then it will not, unless you had sex the same day. the plan b pill is not 100% guaranteed to keep you from getting pregnant. especially if you are mid cycle and ovulating.
