title: Choosing a combined oral contraceptive pill.
abstract: The combined oral contraceptive pill is an effective contraceptive method which can also offer other benefits. However, other contraceptive options should be discussed. If the pill is the chosen method, prescribe a pill with the lowest effective dose of oestrogen and progestogen. Pills containing levonorgestrel or norethisterone in combination with ethinyloestradiol 35 microgram or less are considered first-line. They are effective if taken correctly, have a relatively low risk of venous thromboembolism, and are listed on the Pharmaceutical Benefits Scheme. The pill is usually taken in a monthly cycle. Some women may prefer an extended pill regimen with fewer or no inactive pills.
