Difference Between Loestrin & Loestrin 24

The medications Loestrin and Loestrin 24 use the same ingredients to prevent pregnancy. Several differences exist between the two pills, including the number of active pills, duration of your period and the severity of menstrual side effects.
  1. Quantity of Pills

    • With Loestrin, you will take 21 active pills in each 28-day menstrual cycle. With Loestrin 24, you'll take 24 active pills every 28 days.

    Duration of Period

    • According to the Loestrin 24 website, you will experience a lighter, shorter period while on Loestrin 24 than on pills that have 21 active pills, like Loestrin. The website explains that this lighter and shorter period comes from taking 24 active pills every cycle.

    Easing of Menstrual Side Effects

    • According to a hypothesis by Scott and White Hospital and Clinic, it is possible that the use of Loestrin 24 can ease menstrual symptoms like headaches, stronger emotions and pelvic pain better than Loestrin.
