What is the Combined Pill?

There are basically two types of OCs - the combined oral contraceptive pill which contains both estrogen and progestogen, and the mini-pill which contains progestogen alone. The combined pill is the most commonly prescribed oral contraceptive. Most combined OCs come in 21-pill and 28-pill packages. The 28-pill pack usually contains 21 tablets that contain hormones and 7 tablets, which may contain no hormones called placebos. These pills serve as a reminder to take your pill everyday. Nowadays, OCs with different pill-taking regimens are available as well. These 28-day packs contain less placebo pills which might offer a benefit to you.

Combined OCs contain two hormones estrogen and progestogen, which have a similar effect to the hormones found in your own body. Taken daily, these hormones in the pill prevent your ovaries from releasing eggs (ovulation). Pregnancy will be prevented since there are no eggs to fertilize. The pill also causes changes in the lining of the uterus and the mucus of the cervix which further discourages pregnancy. Since each woman reacts differently to hormones, it may take some time to find the pill that is right for you.

Are there side effects?

Side effects from combined OCs are usually due to the amount of estrogen that the pill contains. Today's low-estrogen oral contraceptives are designed to lessen side effects associated with higher-estrogen formulas. When side effects do occur, they usually disappear after the first 1-3 cycles of pill use. Possible side effects include:

• breakthrough bleeding
• breast tenderness
• headaches
• nausea
• changes in weight
