Microgestin vs. Kyleena
See how Microgestin and Kyleena compare on approved uses, dosing, side effects, and cost.
Key Takeaways
Microgestin is a daily oral contraceptive pill, while Kyleena is a hormonal IUD placed once and left in place for up to five years.
Kyleena's most common side effects are local to the pelvis, such as ovarian cysts and vulvovaginitis, while Microgestin's are more systemic, like nausea and breast tenderness.
Both prevent pregnancy effectively, but Microgestin depends on daily adherence while Kyleena removes that daily responsibility after a single insertion.
Microgestin vs. Kyleena Drug Summary
Microgestin
Microgestin is a combination oral contraceptive containing norethindrone acetate and ethinyl estradiol. It is taken once daily to prevent pregnancy by suppressing ovulation and thickening cervical mucus. It has been available since 1968 and comes in multiple dose strengths and pack formats.
Kyleena
Kyleena is a levonorgestrel-releasing intrauterine device that prevents pregnancy for up to five years after a single insertion. It releases a low, steady dose of hormone directly into the uterus, which limits systemic hormone exposure. It was FDA-approved in 2016 and must be placed and removed by a clinician.

Microgestin vs. Kyleena Pros and Cons
Microgestin
Microgestin offers straightforward daily dosing with decades of clinical use behind it, and its low list price makes it accessible for many patients. Because it relies on consistent daily use and carries cardiovascular warnings for smokers over 35, it may not suit everyone.
Pros
No procedure needed, just a daily pill
Long track record of use since 1968
Available in multiple dose strengths for tolerability
Fertility returns quickly after stopping
Cons
Requires remembering a pill every day
Not recommended for women over 35 who smoke
Increased risk of blood clots, stroke, and heart attack
Effectiveness depends on strict daily adherence
Kyleena
Kyleena offers years of protection from a single insertion, removing the need to remember a daily pill. It requires a clinical procedure and carries device-related risks like perforation or expulsion. Its local hormone delivery limits some of the systemic side effects seen with oral contraceptives.
Pros
One insertion protects against pregnancy for up to 5 years
No daily action needed once in place
Hormone effects are mainly local, limiting systemic exposure
No increased cardiovascular risk tied to smoking status
Cons
Requires an in-office insertion procedure
Risk of uterine perforation during placement
Risk of ovarian cysts, though usually resolves on its own
Small risk of device expulsion or displacement
