What are birth control pills and how do they work?

Birth control pills are also known as oral contraceptives (OCs) or, simply, “the pill.” They offer protection against pregnancy by blocking the union of sperm and egg, thereby preventing conception.

Oral contraceptives or birth control pills contain synthetic female hormones. They work largely by preventing the release of an egg from an ovary, or ovulation. If no egg is released, there can be no pregnancy.

Stopping ovulation is not the only way birth control pills can work. The progestin or synthetic progesterone in birth control pills also changes the physical and chemical environment of the female reproductive tract, making it hostile for sperm.

What are the different types of birth control pills?

The active ingredients in birth control pills are synthetic versions of the female hormones estrogen and progesterone. Combination oral contraceptives are birth control...

Yaz (drospirenone and ethinyl estradiol) is an oral contraceptive. A generic version is available. Yaz is used for preventing pregnancy, treating premenstrual dysphoric disorder (PMDD), and treating moderate acne in females at least 14 years of age. Common side effects of Yaz include headache, menstrual irregularities, nausea, vomiting, breast pain, fatigue, irritability, decreased libido, weight gain, and mood changes. Yaz may increase the risk of blood clots, stroke, and heart attack. It can also increase blood potassium levels.

The usual dose of Yaz is one tablet daily. Nonsteroidal anti-inflammatory drugs or NSAIDs (for example, Motrin), spironolactone, potassium supplements, ACE inhibitors, and angiotensin-II receptor antagonists (ARBs) may contribute to increased potassium levels when combined with Yaz. Drugs that increase or decrease drug metabolism may decrease or increase blood levels of Yaz, respectively. There is little or no increased risk of birth defects in women who inadvertently use oral contraceptives during early pregnancy. Small amounts of the hormones in Yaz are excreted in breast-milk.

Our Yaz Drug Center provides a comprehensive view of available drug information as well as related drugs, user reviews, supplements, and diseases and conditions.

Yaz Consumer Information: Uses

This medication is a combination of 2 hormones: an estrogen (ethinyl estradiol) and a progestin (drospirenone). This product is used to prevent pregnancy. It works mainly by preventing the release of an egg (ovulation) during your menstrual cycle. It also makes vaginal fluid thicker to help prevent sperm from reaching an egg (fertilization) and changes the lining of the uterus (womb) to prevent attachment of a fertilized egg. If a fertilized egg does not attach to the uterus, it passes out of the body.

Besides preventing pregnancy, birth control pills may make your periods more regular, dec...
