What Makes it Different

  • Quasense is an Extended Cycle pill. Women who take Quasense will only have four periods a year. Additionally, each period should only last three days.
  • All brands, including Quasense, that contain the progestin levonorgestrel have been FDA approved for use as an Emergency Contraceptive.
  • Speak to a healthcare professional, before using Quasense as Emergency Contraception.
  • To use Quasense as an Emergency Contraceptive, take all pills no more than 120 hours (five days) after unprotected sex. It is most effective when taken within 72 hours (three days).
  • Dosage for emergency contraception: take four white pills and, exactly 12 hours later, take another four white pills.

How it Works

Quasense (ethinyl estradiol and levonorgestrel) is a combination of the female hormones estrogen and progestin, which work to prevent pregnancy in three ways. First, the hormones prevent ovulation (the release of an egg from one of the ovaries). Quasense also thickens the cervical mucus, which blocks sperm from reaching and fertilizing the egg. Lastly, the hormones prevent the uterine lining from thickening, making it less hospitable to implantation.

Oral contraceptives are only to be utilized as a form of birth control and do not protect against the transmission of HIV (AIDS) or other sexually transmitted infections (STIs).

How to Use

You will take your first pill on the first day of your period or the first Sunday after your period has begun. Use Quasense exactly as your healthcare provider has instructed. In order to maintain the effectiveness of the birth control pill, you must take one pill each day at the same time until the pack is complete.

If you miss a dose of Quasense, your risk of pregnancy will be increased. There are ways to make up for missing a pill that will maintain the effectiveness of the birth control. For further instruction, contact with your healthcare provider immediately upon realizing you’ve missed one or more pills.


Quasense has been shown to prevent pregnancy in over 99% of situations when it is the only birth control method utilized and when Quasense is used exactly as directed.


Most birth control pills cost $15-50 per pack.


Quasense is an Extended Cycle pill. Extended cycle pills allow women to have only four periods a year. Additionally, each period should only last three days.

All birth control pills, Quasense included, have also been shown to possibly have the following benefits:

  • Menstrual cycle may become more regular, and blood flow may become lighter (reducing the chances of anemia)
  • Cramps or other pain during menstruation may become less intense and/or frequent
  • Noncancerous cysts or lumps in the breast may occur less frequently
  • Ectopic pregnancies may occur with less frequency
  • Acute pelvic inflammatory disease may occur less frequently


All birth control pills, including Quasense, can increase your risk of blood clots, stroke and heart attack, especially for women who smoke and/or are older than 35. Women taking oral contraceptives should not smoke.

Possible side effects include

  • Mild Nausea, vomiting, bloating, stomach cramps
  • Headache, nervousness, dizziness or tired feeling
  • Changes in menstrual period
  • Decreased sex drive
  • Breast pain, swelling or tenderness
  • Increased hair growth or loss of scalp hair
