This article discusses Lo Loestrin Fe, its uses, dosage, and side effects. It also discusses some of this drug’s potential interactions.
Uses
Lo Loestrin Fe is used to prevent pregnancy. It also has some benefits beyond preventing pregnancy, including:

Women over 35 who smoke cigarettes should not use Lo Loestrin Fe. This is because of an increased risk for heart attack, blood clots, and stroke. Your risk increases due to age and the number of cigarettes you smoke each day.

A pack of Lo Loestrin Fe contains 28 pills. The first 24 pills in the pack are combination estrogen and progestin pills. This is followed by two days of estrogen-only pills and two more days of placebo pills containing no hormones.
To use, take one pill at the same time every day. Avoid skipping pills. The pills should be taken in the order indicated on the pack.
