Microgynon 30 FAQ

Updated April 17, 2017

A monophasic birth control pill, Microgynon 30 comes in a 28-day tablet pack. A woman consumes 21 days of hormones and is allowed a week of placebo pills, so a menstrual cycle is completed. Like many other birth control pills, there are side effects, precautions and additional warnings. This FAQ will provide helpful information for those looking to try Microgynon 30 for themselves.

What Is Microgynon 30 Used to Treat?

While a pregnancy prevention device, Microgynon 30 is also used to treat acne. Other women's-health conditions such as dysmenorrhoea (painful periods), menorrhagia (heavy periods) and endometriosis are treated with the use of Microgynon 30. Irregular periods and severe cases of PMS can be treated with Microgynon 30 too.

How Does Microgynon 30 Work?

All hormonal birth control pills trick the body into thinking the woman has already menstruated. Ultimately, a birth control thickens the cervical mucus, making it harder for sperm to penetrate into the uterus. This makes pregnancy more difficult. The use of a hormonal birth control pill also creates a shorter, lighter period and you have the ability to skip a menstrual cycle if you desire. This is not recommended for women who first begin using Microgynon 30, as breakthrough bleeding and spotting is common.

What Are Some Side Effects of Microgynon 30?

Side effects vary with each woman that uses it. While the body is adjusting to the hormones being provided daily, various symptoms can occur. These include nausea, breast tenderness, water retention, vomiting, fainting, migraines, weight changes, spotting, breakthrough bleeding, headaches, increased blood pressure, gallstones, depression, lowered sex drive and liver function problems. An increased risk of blood clots also occurs in women who use a hormonal birth control pill. These side effects are not uncommon; however, if they persist a doctor should be consulted. Further instructions on whether or not to continue taking Microgynon 30 should be determined by a health care professional.

What Are Some Precautions Regarding Microgynon 30?

First of all, breakthrough bleeding and/or spotting is common for women who begin using a new birth control pill. Other menstrual irregularities including missed periods can also occur while the body is adjusting to the dosage of hormones being provided to it daily. Pay close attention to your body during the onset use of Microgynon 30. Stop taking Microgynon 30 immediately If you experience any of the following symptoms: swelling of the legs, chest pain, painful breathing, consistent migraines, dizziness, numbness on one side of the body or seizures.

Who Should Not Take Microgynon 30?

Women who smoke, have diabetes, have a history of heart disease or breast cancer in their family and women over 35 all are not recommended to take Microgynon 30. Additional health conditions that may make Microgynon 30 ineffective or unsafe include: severe depression, family history of liver disease, kidney problems or Crohn's Disease. Also, women should never start a new birth control pill if they believe they may be pregnant, or if they are breast-feeding.
