What Is Quasense?

Quasense™ (levonorgestrel/ethinyl estradiol) is an oral contraceptive (birth control pill) and is a generic version of Seasonale®.

Side Effects

As with any medicine, side effects are possible with Quasense. However, not everyone who uses the contraceptive will experience side effects. In fact, most people tolerate it quite well.
If side effects do occur, in most cases, they are minor and either require no treatment or can easily be treated by you or your healthcare provider. Serious side effects are less common.
Common side effects of Quasense include but are not limited to:
  • Breakthrough bleeding or spotting between periods
  • Breast tenderness
  • Nausea
  • Vomiting
