Can the 2 levonorgestrel pills be taken at the same time?
The Plan B blister package contains 2 pills of 0.75 mg of levonorgestrel. The FDA approval for Plan B indicates that 1 pill should be taken immediately and 1 pill in 12 hours.The alternative—taking both pills together—appears to be effective.1 If the patient vomits within 1 hour of taking a pill, she should be prescribed another pill and given an antiemetic prophylactically.
