Clinical Trial Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to the rates in the clinical trials of another drug and may not reflect the rates observed in practice.
The clinical trial that evaluated the safety and efficacy of Seasonique (levonorgestrel, ethinyl estradiol) was a 12-month, randomized, multicenter, open-label study, which enrolled women aged 18-40, of whom 1,006 took at least one dose of Seasonique (levonorgestrel, ethinyl estradiol) .
Adverse Reactions Leading to Study Discontinuation: 16.3% of the women discontinued from the clinical trial due to an adverse reaction; the most common adverse reactions (≥ 1% of women) leading to discontinuation were irregular and/or heavy uterine bleeding (5.9%), weight gain (2.4%), mood changes (1.5%), and acne (1.0%).
Common Treatment-Emergent Adverse Reactions (≥ 5% of women):
irregular and/or heavy uterine bleeding (17%), weight gain (5%), acne (5%).
Serious Adverse Reactions: migraine, cholecystitis, cholelithiasis, pancreatitis, abdominal pain, and major depressive disorder.
The following adverse reactions have been identified during post-approval use of Seasonique (levonorgestrel, ethinyl estradiol) .
