It depends: It depends on how your pills were packaged. What you should take is 1.5mg of levonorgestrel (LNG) as soon as possible. Some "morning after" pills are packaged as just 1 pill which is 1.5mg of LNG, and others are packaged as 2 pills, each one being 1/2 the dose (0.75mg LNG). If your pills were packaged as two pills, you should just take both pills as soon as possible - don't wait.

Package insert: I’m not sure what type of plan B is available in Singapore. Check the package insert for the instructions for use. Plan B one step is taken as a single dose. Other versions of Plan B come in two doses taking 12 hours apart. The package insert should include the instructions for use on the particular brand that you purchased
