Microgestin vs. NuvaRing
See how Microgestin and NuvaRing compare on approved uses, dosing, side effects, and cost.
Key Takeaways
Microgestin is a daily oral contraceptive pill, while NuvaRing is a vaginal ring changed once a month, so the biggest practical difference is how often you have to remember to use it.
Both prevent pregnancy effectively when used correctly, but NuvaRing's monthly schedule requires less daily attention than Microgestin's pill schedule.
Microgestin typically costs far less out of pocket than NuvaRing, whose list price can run several times higher without insurance coverage.

Microgestin vs. NuvaRing Pros and Cons
Microgestin
Microgestin has decades of real-world use since its 1968 approval and is one of the lowest-cost combination birth control options available. Like other oral contraceptives, its effectiveness depends on remembering a pill at roughly the same time every day.
Pros
Roughly $20 to $50 per month without insurance
Long safety track record dating back to 1968
Multiple dose strengths let clinicians tailor hormone levels
Iron-supplemented (Fe) versions available for the pill-free week
Cons
Must be taken at the same time every day to stay effective
Missing pills raises pregnancy risk more than with the ring
Higher reported rate of vaginal candidiasis (6.1%)
Requires refilling a pack every month
NuvaRing
NuvaRing offers a once-monthly routine instead of a daily pill, which some people find easier to stick with. It costs substantially more out of pocket than Microgestin and requires comfort with vaginal insertion and removal.
Pros
Only needs to be changed once a month
No daily pill-taking, so fewer chances to miss a dose
Ring-free week naturally times a withdrawal bleed
Generic versions now available
Cons
Roughly $200 to $584 per month without insurance
Requires inserting and removing a vaginal ring
Higher reported rate of vaginitis (13.8%)
