Choosing the right birth control can feel overwhelming with so many options available. One common type is drospirenone, a hormonal contraceptive found in several birth control pills. You might have heard of brands like Yaz® or Yasmin®, which include this ingredient.
Drospirenone is often combined with another hormone, ethinyl estradiol, to prevent pregnancy. It influences your body's natural hormones to stop ovulation, which means no egg is released for fertilization. But like any medication, it has potential benefits, risks, and side effects.
This article provides an overview of drospirenone-based contraceptives, how they work for birth control, their benefits, and the possible side effects to help guide informed discussions with your healthcare provider.

What is Drospirenone?
Drospirenone is a synthetic hormone belonging to a class of medications called progestins. Progestins are man-made versions of the natural hormone progesterone, vital in regulating the menstrual cycle and supporting pregnancy.
In hormonal contraceptives, drospirenone is often paired with estrogen, like ethinyl estradiol, to prevent pregnancy. Examples include branded products such as Yaz® and Yasmin®.
Mechanism of Action
Drospirenone works in several ways to prevent pregnancy.
- First, it stops ovulation, which is the release of an egg from the ovaries. Without an egg, fertilization cannot occur.
- Second, it thickens the cervical mucus, forming a barrier that hinders sperm from passing through the cervix to reach the egg.
- Lastly, drospirenone helps thin the lining of the uterus (the endometrium). A thinner lining is less suitable for implantation, meaning a fertilized egg is less likely to attach and develop.
Another unique feature of drospirenone is its impact on water retention and bloating due to its diuretic properties. It blocks the effects of a hormone called aldosterone, which helps the body regulate salt and water balance.
This is why drospirenone is sometimes chosen by women who experience bloating or swelling during their menstrual cycle.
Consult your healthcare provider for more information on whether this contraceptive suits you.
Benefits of Drospirenone
Drospirenone has become a popular choice for birth control due to its unique benefits beyond pregnancy prevention.
It combines effective contraception with additional health advantages, which may make it suitable for individuals looking to manage specific hormonal-related symptoms or conditions.
Contraceptive Effectiveness
Drospirenone is highly effective when used as part of a combination birth control pill.
When taken correctly—meaning at the same time every day—it has a pregnancy prevention rate of over 99%. This means fewer than 1 in 100 women will become pregnant each year while using drospirenone-containing pills as directed.
However, with "typical use" (occasional missed pills), the effectiveness drops slightly to about 93%. This makes drospirenone a reliable contraceptive option for individuals who can commit to a daily routine.
Additional Benefits
Drospirenone offers several advantages beyond contraception, making it a preferred choice for many.
Acne Reduction
Drospirenone-containing pills are often prescribed to help reduce acne. They work by lowering androgen levels (male hormones that can contribute to acne) and reducing excess oil production in the skin.
Studies have shown that contraceptives like Yaz® and Yasmin®, which contain drospirenone, can significantly improve moderate acne over time.
PMS and PMDD Symptom Relief
Drospirenone may help alleviate symptoms of premenstrual syndrome (PMS) and premenstrual dysphoric disorder (PMDD), a more severe form of PMS.
Symptoms like mood swings, irritability, and bloating may improve with the use of drospirenone-containing birth control, as it helps stabilize hormonal fluctuations during the menstrual cycle.
Water Retention Control
Drospirenone has a mild diuretic effect, aiding the body in removing excess water and salt. This can mitigate the bloating and swelling that some women experience before their period.
Unlike other progestins, drospirenone counteracts the water-retaining effects of estrogen, making it unique in this regard.
Drospirenone for PCOS
Polycystic ovary syndrome (PCOS) is a hormonal condition that may lead to irregular periods, acne, excess hair growth, and difficulty with ovulation.
Birth control pills containing drospirenone may help manage some symptoms of PCOS by:
- Regulating Menstrual Cycles: When combined with estrogen, drospirenone can assist in regulating menstrual cycles in women with PCOS. This reduces the risk of endometrial thickening, which can occur when periods are irregular.
- Reducing Androgen Levels: PCOS is often associated with high androgen levels, which can cause acne, hair growth on the face or body, and scalp hair thinning. Drospirenone helps lower androgen activity, improving skin and hair-related symptoms.
- Improving Acne: Since acne is a common concern for individuals with PCOS, drospirenone-containing pills may be particularly beneficial due to their anti-androgenic properties.
While drospirenone does not treat the root cause of PCOS, it can help manage many of its symptoms, improving the quality of life for those with the condition.
Risks and Side Effects
While drospirenone offers many benefits, knowing its potential risks and side effects is essential. Knowing these can help you and your healthcare provider weigh the pros and cons and decide if this type of birth control is right for you.
Some side effects are mild and temporary, while others may be more serious and require medical attention.
Common Side Effects
Most people tolerate drospirenone well, but some may experience mild side effects, especially during the first few months of use. These side effects often improve as your body adjusts to the hormones:
- Spotting or Breakthrough Bleeding: Light bleeding between periods is common, especially when starting drospirenone. This typically resolves within a few cycles.
- Nausea: Some users may feel mildly nauseous after taking the pill, especially if it's taken on an empty stomach. Taking it with food or at bedtime can help reduce this symptom.
- Mood Changes: Some people report mood swings, irritability, or changes in emotional well-being while using hormonal birth control. If mood changes are severe or persist, consult your doctor.
- Breast Tenderness: Mild swelling or soreness in the breasts may occur, particularly during the first few months.
- Headaches: Hormonal changes can trigger mild headaches in some individuals.
These common side effects are typically manageable and don't require medical intervention unless they persist or worsen.
Serious Risks
Although rare, drospirenone can carry more serious risks, particularly for individuals with certain health conditions.
Blood Clots (Venous Thromboembolism)
Drospirenone has been associated with a slightly increased risk of blood clots compared to other progestins. Clots could develop in the legs (deep vein thrombosis, or DVT) and, in rare cases, travel to the lungs (pulmonary embolism, or PE).
Symptoms to watch for:
- Swelling, pain, or redness in the legs
- Shortness of breath or chest pain
- Sudden dizziness or fainting
Cardiovascular Risks
The use of drospirenone-containing birth control may slightly increase the risk of stroke or heart attack, particularly in people who smoke, are over the age of 35, or have underlying cardiovascular conditions like high blood pressure.
Elevated Potassium Levels (Hyperkalemia)
Drospirenone has a mild diuretic effect and can raise potassium levels in the blood. This is generally not a concern for healthy individuals.
Still, it can be risky for people with kidney or adrenal problems, or those taking medications that also raise potassium levels (like certain blood pressure medications).
If you experience any serious symptoms, such as severe chest pain, difficulty breathing, or unusual swelling, seek immediate medical attention.
Comparing Drospirenone with Other Options
Birth control is not a one-size-fits-all solution. Different progestins (synthetic progesterones) are used in contraceptives, and each has unique properties.
Drospirenone vs. Levonorgestrel
Levonorgestrel is one of the most widely used progestins in birth control. It's found in many combination pills, the hormonal IUD (e.g., Mirena) and emergency contraception pills (e.g., Plan B).
Both drospirenone and levonorgestrel-containing birth control pills are highly effective when taken as directed, with over 99% effectiveness in preventing pregnancy.
Levonorgestrel is also used in long-acting contraceptives like IUDs, which can protect for 3–7 years, depending on the brand.
Drospirenone, on the other hand, is primarily available as a daily oral pill or in combination pills.
Side Effects
Drospirenone is known for its anti-androgenic and mild diuretic properties, which can help reduce acne, water retention, and premenstrual bloating. However, compared to levonorgestrel, it carries a slightly higher risk of blood clots.
Levonorgestrel may cause more androgenic side effects, such as increased oiliness of the skin, acne, or unwanted hair growth, particularly in individuals sensitive to hormonal fluctuations.
It has a lower risk of blood clots than drospirenone, making it a preferred option for people with a history of clotting disorders.
Always discuss the use of oral contraceptives with a trusted physician to ensure safety and effectiveness.
Branded Options Containing Drospirenone
There are several birth control pills and formulations containing drospirenone, each tailored to different needs. Here's an overview of popular brands:
Yaz®
- Contains drospirenone and ethinyl estradiol.
- Often prescribed for contraceptive use and to manage moderate acne or premenstrual dysphoric disorder (PMDD).
- Taken as a 24/4 regimen (24 active pills and 4 placebo pills), which means shorter, lighter periods.
Yasmin®
- Similar to Yaz®, but it follows a 21/7 regimen (21 active pills and 7 placebo pills).
- Used for contraception and acne management, offering a more traditional pill schedule.
Slynd®
- A progestin-only pill (POP) containing drospirenone that is unique because most progestin-only pills use different progestins like norethindrone.
- It does not contain estrogen, making it a good choice for individuals who cannot tolerate estrogen or are at higher risk for complications like blood clots.
- It comes with a flexible dosing window, meaning it's slightly more forgiving if a dose is taken late compared to other progestin-only pills.
FAQs About Drospirenone
Here are commonly asked questions and answers about Drospirenone.
Is Drospirenone Safe?
When used as directed, drospirenone is considered safe for most people. However, it carries a slightly higher risk of blood clots than other progestins.
It is important to avoid smoking, especially if you're over 35, and to discuss your medical history with your doctor to assess risks.
Can It Cause Weight Gain?
Drospirenone is less likely to contribute to weight gain compared to other hormonal contraceptives. Its mild diuretic effect can help reduce water retention and bloating. Most reported weight changes with birth control are due to fluid shifts, not fat gain.
How to Minimize Risks?
Take the pill at the same time daily to maintain effectiveness.
Avoid smoking, especially if you're over 35, and inform your physician about any history of blood clots, high blood pressure, or kidney issues.
Stay hydrated and maintain a healthy lifestyle to promote overall well-being.
