AI Statement
Jencycla 0.35 mg contains the progestogen (progestin) desogestrel 0.35 mg.
Label Reference
DETAILED PATIENT LABELING header: "Jencycla™ (norethindrone tablets USP, 0.35 mg)" (active ingredient shown as norethindrone, not desogestrel).

Moderate
Safety Assessment
Potential Patient Risk:
Moderate
