Femcon Fe is the first chewable combination birth control pill approved by the U.S. Food and Drug Administration (FDA) that, when taken every day, can help prevent pregnancy. Each pills contains 0.4 milligrams (mg) of norethindrone (a progestin) and 35 micrograms (mcg) of ethinyl estradiol (estrogen).

Femcon Fe pills are 92% and 99.7% effective in preventing pregnancy. This means that with typical use, only 8 of every 100 users will become pregnant during the first year of use. With perfect use, less than 1% will become pregnant.

Femcon Fe offers no protection against sexually transmitted infections (STIs).

How to Take

Femcon Fe works like other combination birth control pills. Each pack supplies a steady dose of norethindrone and ethinyl estradiol to last for one month (with 21 hormone pills and seven reminder pills).

Follow your healthcare provider’s advice as to when to begin. Most likely, you will start on the first day of your period or on the first Sunday after your period has begun.

After opening the pack, take out the label and peel and stick it to your pill pack, which will indicate your start date and show you the order to take the pills. Pick a time that you will take your pill each day.

Femcon Fe is a small, spearmint-flavored pill that can be either swallowed or chewed. If you decide to chew the pill, you must wash it down with an 8-ounce glass of any drink. Whether you decide to swallow or chew the pill does not alter its effectiveness

Do not dissolve Femcon Fe pills in your mouth. This can affect its absorption and the bioavailability of estrogen and progestin in the bloodstream.


There are certain advantages to taking Femcon Fe compared to other types of hormonal and non-hormonal birth control. Among them:

  • Femcon Fe is completely reversible. The ability to become pregnant returns after you stop taking the pill.
  • It's the only oral contraceptive that can be chewed, so it is ideal for people who have difficulty swallowing pills.
  • It is discreet and gives the user the flexibility to take it on the go.
  • Femcon Fe can help lighten menstrual flow and improve irregular periods.​
  • Unlike condoms, Femcon Fe doesn't interfere with sex and allows for more spontaneity.
  • It may help reduce menstrual cramps.

There is a low incidence of spotting or breakthrough bleeding between periods while on Femcon Fe. According to an older three-year study in the Journal of Reproductive Medicine, 92% of study participants who took Femcon Fe experienced no breakthrough bleeding.
