Drug Description


Select 28-day contraceptive pills are a type of combined hormonal contraceptive (CHC) that are designed to be taken daily for 28 days to prevent unplanned pregnancies.  

These pills contain a combination of hormones, typically Ethinyl estradiol and Norethindrone, that work together to prevent ovulation and create a barrier for sperm to reach the egg for fertilization. 

Use and Dosage 

Select 28-day tablets should be taken at the same time each day, with or without food. Begin taking the pills on either the first day of your menstrual cycle, or on the first Sunday after the start of your menstrual cycle. 

The 28-day contraceptive pack will typically contain 21 active pills and 7 inactive or placebo pills. Begin by taking one active pill daily, starting from the first day of your menstrual cycle or as directed by your healthcare provider. Take the active pills at the same time each day to maintain the effectiveness of the contraceptive. Setting a daily reminder or using alarms can help you remember to take the pill consistently. 

Take one active pill every day for 21 days, ensuring you don’t miss any doses. This will provide continuous hormone levels to prevent ovulation and protect against unplanned pregnancies. After completing the 21 days of active pills, switch to the 7 inactive or placebo pills. These pills do not contain hormones but are included to help you maintain a daily pill-taking routine. During this time, you may experience a withdrawal bleed, similar to a period. After completing the 21 days of active pills, switch to the 7 inactive or placebo pills. After taking all 7 inactive pills, begin a new pack of Select 28-day contraceptive tablets, starting with the active pills. Continue this cycle of taking active pills for 21 days, followed by the inactive pills for 7 days.
