What is Loestrin 1/20?
Loestrin 1/20 is a brand of combined oral contraceptive pills. It contains two hormones: ethinyl estradiol (20 mcg) and norethindrone (1 mg) in each active tablet.
What is it used for?
Loestrin 1/20 is prescribed to prevent pregnancy. Like other combined birth-control pills, it can also be used for menstrual cycle regulation when a clinician recommends it.
How do you take Loestrin 1/20?
Loestrin 1/20 is taken by mouth once daily on a schedule laid out on the prescription label. Most combined pill packs include active pills and some packs include inactive/placebo pills, so the key is to follow the specific pack instructions provided with your medication.
What should you watch for (side effects and risks)?
Common side effects can include spotting between periods, nausea, breast tenderness, and headaches. Like all combined estrogen/progestin contraceptives, there is a risk of serious blood clots (such as deep vein thrombosis or pulmonary embolism), especially in people who smoke, are over 35, or have certain medical risk factors. Your prescriber can assess your personal risk.
What if someone asks about “generic” Loestrin 1/20?
Loestrin 1/20 has had generic equivalents (same or equivalent hormone doses) depending on the market and availability. If you’re shopping by cost, ask your pharmacist for the closest equivalent by active ingredient and strength rather than only the brand name.
