The Pill for Hormone Treatment
How does the pill work?
Estrogen and progesterone are hormones released from your ovaries. When you take hormone pills (also called the pill), your body knows that estrogen and progesterone are coming from somewhere else - from the pills. Because your ovaries don't need to release hormones, they take a little nap. While the ovaries are napping, they don't release hormones, and don't release an egg, which is how the pill works for period control.
The pill can be used to treat other conditions affected by estrogen and progesterone. These include irregular or absent menstrual periods, menstrual cramps, acne, PMS, endometriosis, Primary Ovarian Insufficiency (POI) or Polycystic Ovary Syndrome (PCOS). The pill can help regulate hormone levels, which may ease symptoms like headaches, acne, or bleeding.
Forgetting pills or taking them at different times of the day can cause the ovaries to wake up. When that happens, the ovaries release hormones and may release an egg, which can cause irregular bleeding.
How do I use the pill?
- Start your first pack of pills as directed.
- You may be told to start on the first day of your next period, or
- On the Sunday after your next period begins, or
- On the day you are in the clinic or office.
- After starting the pill, continue taking 1 pill every day. There should not be any days that you do not take a pill.
- In the package of pills the first 21-24 days are hormone pills and the last 4 to 7 are usually sugar pills (placebo). Most people start their bleeding on the second or third day of the placebo pills.
- If you are taking the pills with an extended cycle, your doctor will tell you when to expect bleeding.
What if I forget to take a pill?
- If you forget to take a hormone pill at your usual time, take your pill as soon as you remember. Then take the next pill at the usual time. You will be taking 2 pills that day.
- If you forget to take a hormone pill for 1 whole day, take 2 hormone pills the next day at the regular time.
- If you forget to take a hormone pill for 2 days, take 2 hormone pills for each of the next 2 days.
- If you forget to take the pill for 3 days, your ovaries may wake back up. Start a new pack of pills.
- Forgotten placebo pills do not need to be made up.
- If you have questions about what to do with missed or late pills, call the clinic.
What are the side effects?
Most people do not have any side effects with the pill. However, during the first 3 months you may experience:
- Bleeding or spotting during the hormone pills. This is called breakthrough bleeding and usually happens more during month 1, less during month 2, and by month 3 most people have regular periods during the last week of pills. If breakthrough bleeding continues after month 3, you may need a different pill.
- While other side effects are not common, you may have nausea, breast tenderness, headaches, or mood changes. If this happens, it is usually mild and doesn't last long.
- If you are having side effects that are making you feel miserable, call the clinic. Do not stop taking your pills.
- The pill does notcause weight gain.
