Key takeaways
Junel Fe 24 (norethindrone acetate / ethinyl estradiol/ f errous fumarate) and Lo Loestrin Fe (norethindrone acetate / ethinyl estradiol / ferrous fumarate) are both combined oral contraceptives (COCs) used to prevent pregnancy. They contain the same active ingredients, norethindrone acetate (a progestin) and ethinyl estradiol (an estrogen), and ferrous fumarate (a form of iron) but differ in their formulation and dosing. Junel Fe 24 is a monophasic contraceptive, meaning all active pills have the same hormone levels, and it includes 24 active tablets and 4 placebo tablets. In contrast, Lo Loestrin Fe is a biphasic contraceptive with 26 active tablets and 2 placebo tablets, and it has a lower dose of ethinyl estradiol. Junel Fe 24 is available as a lower-cost generic, while Lo Loestrin Fe does not have a generic version. Other generics similar to Junel Fe 24 include Aurovela 24 Fe, Blisovi 24 Fe, and Hailey 24 Fe. Common side effects for both include nausea, headache, and breast tenderness. Both medications can increase the risk of blood clots, especially if you smoke and are over 35 years old. Additionally, certain medications like rifampin can interact with both contraceptives, reducing their effectiveness.
