What is LoviOne 1.5 mg tablet (levonorgestrel)?

LoviOne 1.5 mg Tablet (levonorgestrel) is an oral emergency contraceptive pill, also known as the morning after pill, now available without a prescription from pharmacy. The tablet contains 1.5 mg of levonorgestrel to help protect against unplanned pregnancy after unprotected sex. It is most effective when used as soon as possible and must be used within 72 hours (3 days) after unprotected sex.

Unprotected sex could be:

  • No contraception was used during sexual intercourse.
  • The contraception method failed e.g. a condom broke or slipped off
  • The contraception method was used incorrectly e.g. a pill free break when taking progesterone only pill
  • Missing more than one contraceptive pill in a row.


The active ingredient in LoviOne, levonorgestrel, is a progestin, a synthetic version of the naturally occurring hormone progesterone.

LoviOne can be taken to prevent pregnancy, but it is important to note that LoviOne will not terminate a pregnancy, therefore is not an abortive pill.

LoviOne aims to provide reassurance and empower women to self-care and encourage them to take control of their health.

LoviOne is most effective if taken within 24-hours of unprotected sex. It is 99% effective when taken within 1 day1 and 84% effective when taken within 3 days2.
