Most women can safely use birth control pills. However, as with all medications, they do have possible side effects and risks.
Here’s a rundown of the pros and cons of using oral contraceptives, including common side effects.
Pros of the Birth Control Pill
Obviously, the main reasons to take the birth control pill are to prevent pregnancy and regulate the menstrual cycle. Some of the pill’s benefits include:
It is 99% effective when used as directed. It is a very convenient and safe method of contraception. It allows for sexual spontaneity (so you don’t have to plan in advance). It can lead to lighter periods. It can decrease the discomfort of menstrual cramps. Combination pills can be taken to change the timing and frequency of your period or to skip your period altogether.
Other Benefits
Combination birth control pills that include both estrogen and progestin can also provide other health benefits. They may offer some protection against:
Osteoporosis Iron deficiency anemia (which can result from having heavy periods) Pelvic inflammatory disease (which, if left untreated, can cause infertility) Ovarian cysts Acne Vaginal dryness and painful intercourse Noncancerous breast growths Excess body hair Menstrual migraines Symptoms of premenstrual dysphoric disorder (PMDD)
Cancer Protection and the Pill
Research suggests that birth control pills can lower the risk of ovarian cancer by 27% and the risk of endometrial cancer by 50% compared to other types of contraceptives.
Protection against developing these cancers can last up to 30 years after stopping combination birth control pills. Plus, protection increases with each year of use. If you use combination pills for six years, your risk of ovarian or endometrial cancer will be lowered by up to 60%.
Studies also show that women who take the pill are 15% to 20% less likely to get colorectal cancer.
Cons of the Birth Control Pill
If you use birth control pills, you may experience some side effects. The good news is that most of these side effects will go away by the second or third month of use as your body adjusts to the hormones in the pill.
Birth control pill side effects may include:
HeadachesBreast tendernessNausea (sometimes with vomiting)Bleeding between periods
Combination birth control pills may also cause:
Depression Changes in libido (sexual desire)
Progestin-only birth control pills may lead to irregular spotting and bleeding more frequently than combination pills.
Managing Side Effects
You should read the paper insert that comes inside your pill pack for more detailed information about how to use them and what the side effects are. The insert should also explain when to take your birth control pills and what to do if you miss a pill.
You can take your birth control pill with an evening meal or at bedtime to help decrease nausea and/or vomiting.
Side effects are a common reason why people stop taking birth control pills. Talk to your healthcare provider to see if changing to a different brand of pill may help, especially if the side effects last longer than three months.
Risks and Complications
Serious problems do not occur very often with the pill. In fact, birth control pills are much safer than pregnancy and childbirth.
The most serious potential complication of combination birth control pill is developing a blood clot in your heart, lungs, brain, or legs.
The risk is increased in:
Women who smoke Women age 35 or older Women who have high cholesterol, high blood pressure, diabetes, and conditions that increase the risk of blood clotting Women who are confined to bed rest or are wearing a cast
If you have a history of depression, you may not be able to continue to take birth control pills if your depression worsens.
Certain medications can lower the pill’s effectiveness. Therefore, always tell your healthcare provider about any medications you are taking when discussing the pill. Once you are on the pill, always include the brand you are taking when you are asked for a list of your medications.
Pill brands like Yaz and Beyaz contain drospirenone. These pills may have an interaction with medications that increase potassium, such as angiotensin-converting enzyme (ACE) inhibitors and beta blockers. Potassium is a mineral in your blood that helps regulate your heartbeat and blood pressure, among other things.
Summary
Birth control pills have been on the market since 1960 and are considered very effective and safe to use. They are 99% effective in preventing pregnancy when used as directed.
Birth control pills have other health benefits. They can lessen the pain of menstrual cramps, keep acne under control, and protect against certain cancers.
As with all medications, they do have some potential risks and side effects. These include an increased risk of blood clots and a small increase in breast cancer risk.
A Word From Verywell
You and your healthcare provider should discuss the pros and cons of the pill for you specifically. It can take a few months for side effects to go away completely. If you continue to have side effects, your doctor may want you to switch to a different brand. It may take some trial and error with various pill brands until you find the brand that works best with your body.
