What Is This Medicine and How Does It Work in Your Body?

Simply put, this is a hormone pill. It contains artificial versions of two natural female hormones: estrogen and progestin. The main job of this medicine is to stop ovulation. This preventing your ovaries from releasing an egg.

If your body does not release an egg, pregnancy cannot happen. This is why people widely use these pills as an effective birth control method.

Sometimes, doctors also prescribe this specific medicine to help treat stubborn acne on the face. This works because hormone imbalances often play a big role in causing certain types of acne.

Things You Must Tell Your Doctor Before Starting This Medicine

Before you start taking this pill, your doctor needs to know your full health history. If you have or ever had any of the medical conditions listed below, you must tell your doctor right away.

  • Any unusual bleeding from your vagina.
  • A history or current diagnosis of cancer in your breast, cervix, uterus, ovaries, or liver.
  • Diabetes mellitus.
  • High blood pressure.
  • High levels of cholesterol or triglycerides in your blood.
  • Heart disease or a recent heart attack.
  • Diseases affecting your blood vessels.
  • A past history of blood clots.
  • A history of a stroke.
  • Severe migraine headaches.
  • Liver or kidney disease.

  • If you smoke cigarettes, which is very important.
  • If you recently gave birth or experienced a miscarriage.
  • If you are preparing for a major surgery.
  • If you think you might be pregnant or are trying to get pregnant.
  • If you are breastfeeding a baby.
  • If you have known allergies to other medicines, foods, or dyes.

How Do You Take These Pills Correctly?

You take these pills by mouth. Some people feel a little bit of nausea when they swallow them. To help lower that sick feeling, taking your pill right after a meal is a good idea.

The most important rule is to take your pill at the exact same time every day. Choose a time of day that is easiest for you to remember. A great example is taking it every night right after dinner.

Always follow the exact order printed on your pill pack. The package arrows show you the correct daily sequence. Unless your doctor tells you otherwise, never take more than one pill in a single day.

What Should You Do If You Miss a Pill?

If you forget to take your pill on any day, check the patient information leaflet that comes inside your medicine box for guidance. Usually, you should take the missed pill the moment you remember, and then take your regular pill at the normal time that day. However, if you forget to take your pills for two or three days in a row, the birth control protection can drop greatly. During times like this, you must use a backup birth control method like a condom and talk to your doctor right away.

What Happens If You Take Too Much Medicine?
