What is Microgestin FE 1/20?
Microgestin FE 1/20 (also written as Microgestin Fe 1/20) is a prescription birth control pill that combines two hormones: ethinyl estradiol and norethindrone acetate. It’s used to prevent pregnancy. It comes as a 28-day pack that includes hormone tablets and a set of inactive (placebo) tablets, commonly marketed as “FE” to indicate the inclusion of inactive tablets that contain iron during part of the cycle.
What does “1/20” mean?
The “1/20” refers to the hormone strength in the active tablets: about 1 mg of norethindrone acetate and 20 micrograms of ethinyl estradiol per active pill (the exact naming follows the product’s standardized labeling).
How is it taken (28-day cycle)?
Most combined oral contraceptives in this dosing family follow a 28-day regimen: you take active hormone pills for a set number of days, then take the remaining placebo/inactive pills (the “FE” component) for the rest of the month so you keep a routine. You start each new pack on schedule after the placebo/inactive pills.
Is it the same as other Microgestin products?
No. Microgestin FE 1/20 is a specific formulation (the “1/20” strength). Other Microgestin versions use different hormone doses (such as different ethinyl estradiol or progestin amounts), which can matter for side effects and how your clinician chooses a pill.
Who should avoid combined birth control pills?
Combined pills like Microgestin FE 1/20 aren’t appropriate for everyone. They can be unsafe for people with certain conditions (for example, some clotting risks, specific migraine patterns, uncontrolled high blood pressure, or pregnancy). If you tell me your age, health conditions, and whether you smoke, I can help narrow what to ask your clinician or pharmacist.
Common side effects people ask about
Common early side effects can include nausea, breast tenderness, spotting or breakthrough bleeding, headache, and mood changes. These often improve after the first couple of packs, but persistent or heavy bleeding should be discussed with a clinician.
