Spotting With Loestrin 24 Fe

In 2013, the manufacturer of Loestrin 24 Fe decided to stop making this medication and replace it with Minastrin™ 24 Fe, which comes in exactly the same strengths but is chewable. 
Loestrin® 24 Fe (norethindrone/ethinyl estradiol) is a combined oral contraceptive that contains both a progestin and an estrogen. It works to prevent pregnancy primarily by stopping ovulation, but has a few other effects on the body as well. The product comes in packs of 28 tablets. One tablet is taken by mouth each day, ideally at the same time each day.
In clinical studies that documented side effects of Loestrin 24 Fe, spotting occurred in 2 to 6 percent of women taking this drug. This is also called "breakthrough bleeding," and it occurs between normal periods.
In addition to spotting, you may find that Loestrin 24 Fe causes a change in your menstrual bleeding. Some women report lighter, shorter periods while taking this birth control pill, which is fairly normal. If you experience abnormal bleeding, however, or bleeding that is heavier than normal, contact your healthcare provider right away.
