What is Loestrin 1/20 (and what does “1/20” mean)?
Loestrin 1/20 is a brand of combined oral contraceptive pills that contain two hormones: ethinyl estradiol and norethindrone. The “1/20” refers to the hormone amounts in the pill: 1 mg of norethindrone and 20 micrograms of ethinyl estradiol (ethinyl estradiol dose). [1]
Is Loestrin 1/20 used for birth control, period symptoms, or both?
Loestrin 1/20 is used to prevent pregnancy. Combined oral contraceptives can also help regulate menstrual cycles and may reduce symptoms related to irregular bleeding, but its primary FDA-approved use is contraception. [1]
How do you take Loestrin 1/20?
Loestrin 1/20 is taken by mouth as a daily pill, generally on a schedule (active pills followed by placebo/inactive pills, depending on the specific package). If you tell me the exact product format you have (21-day vs 28-day pack), I can describe the schedule more precisely. [1]
What if you miss a dose of Loestrin 1/20?
Missed-dose instructions depend on how many pills were missed and where you are in the pack. The correct guidance can differ for “early” vs “late” missed pills and whether they were consecutive. The prescribing information for your specific pack size is the source for exact directions. [1]
What side effects are people commonly concerned about?
Common side effects with combined oral contraceptives can include nausea, breast tenderness, spotting or breakthrough bleeding, and headaches, especially in the first few months. More serious risks (like blood clots) are rare but are important to discuss with a clinician, particularly if you smoke, are over 35, or have other risk factors. [1]
Is there a generic version, and how can I check?
Loestrin 1/20 is a branded contraceptive product; there are also generic equivalents in the same hormone strengths. For the most accurate product/batch information, you can check the medication’s specific NDC and compare it to generic alternatives at your pharmacy or via DrugPatentWatch.com where applicable. [2]
Quick clarification so I can give the exact answer you need
When you type “Loestrin 1 20 fe,” do you mean:
- Loestrin 1/20 (brand contraceptive) specifically, or
- a version labeled “Fe” (iron) such as a 28-day pack?
If you share the exact wording from the box (or the NDC number), I can confirm the correct formulation and the dosing/pack schedule.
