Oral Contraceptives for PCOS: Regulating Periods and More

Struggling with PCOS symptoms like irregular periods, acne, or unwanted hair growth? Oral contraceptives might be the solution you're looking for.

PCOS (Polycystic Ovary Syndrome) affects millions of women, often causing hormonal imbalances that disrupt menstrual cycles and lead to symptoms like excess hair, acne, and weight gain. Oral contraceptives are a first-line treatment for PCOS, offering relief by:

• Regulating menstrual cycles for more predictable periods.
• Reducing acne by lowering androgen levels.
• Managing excess hair growth through hormonal balance.
• Lowering the risk of endometrial cancer by protecting the uterine lining.

While these benefits make oral contraceptives a popular choice, there are potential risks, including blood clots and cardiovascular concerns, especially for women with certain health conditions. A personalized treatment plan, guided by a healthcare provider, ensures the safest and most effective approach.

How Oral Contraceptives Regulate Periods in PCOS

For women dealing with PCOS, irregular or even absent periods are a common and frustrating challenge. Combined oral contraceptives (COCs) are often the go-to treatment, as they work by adjusting hormonal interactions to help restore regular menstrual cycles.

Balancing Hormone Levels

COCs combine estrogen and progestin to regulate the menstrual cycle. This combination addresses the hormonal imbalances behind irregular periods. The progestin in COCs inhibits gonadotropin-releasing hormone (GnRH) and suppresses luteinizing hormone (LH) surges, effectively preventing ovulation.

"By suppressing LH secretion, the progestin component of COCs inhibits ovarian androgen production, whereas the estradiol component reduces serum free androgen concentrations by increasing SHBG levels."

• Seda Hanife Oguz, Division of Endocrinology and Metabolism, Department of Internal Medicine, Hacettepe University School of Medicine

COCs not only increase estrogen but also lower testosterone levels, directly addressing the hormonal disruptions caused by PCOS. To minimize side effects, healthcare providers typically prescribe the lowest effective dose of estrogen, usually 20–30 μg of ethinyl estradiol (EE). This hormonal adjustment sets the stage for more predictable menstrual cycles.

Creating Regular Menstrual Cycles

Once hormone levels are balanced, women often experience predictable, 28-day cycles. COCs also help lighten periods, which can be a relief for those dealing with heavy or erratic bleeding. In fact, studies show that COCs can reduce heavy menstrual bleeding by 50% in about 80% of women.

Beyond regulating cycles, COCs play a protective role in reproductive health. They prevent excessive estrogen from overstimulating the endometrium, which lowers the risk of endometrial hyperplasia and cancer. This is particularly important for women with PCOS, who are more vulnerable to these conditions due to prolonged unopposed estrogen exposure.

"Combined oral contraceptive (COC) is the first-line pharmacological treatment for the management of menstrual irregularities in PCOS, offering, in addition to contraception, protection of the endometrium."

• Poli Mara Spritzer, MD, PhD, Gynecological Endocrinology Unit, Division of Endocrinology, Hospital de Clínicas de Porto Alegre

Doctors often recommend a six-month trial of COCs to evaluate how well the treatment is working. Many women notice improvements in cycle regularity within just a few months. However, it’s essential to assess cardiometabolic risk factors before starting COCs, as part of a comprehensive approach to managing PCOS.

Other PCOS Symptoms Oral Contraceptives Can Treat

Oral contraceptives are often prescribed to regulate periods in women with PCOS, but their benefits go beyond just menstrual cycle management. These medications can also address other symptoms like acne and unwanted hair growth, making them a well-rounded treatment option for many individuals. By balancing hormone levels, oral contraceptives help improve both skin and hair-related issues.

Clearing Acne and Improving Skin

Acne is a common struggle for women with PCOS due to elevated androgen levels, which increase oil production in the skin. Combination oral contraceptives - containing both estrogen and progestin - help reduce acne by lowering sebum production. It’s important to note that progestin-only pills may actually worsen acne, so combination options are the go-to choice. The FDA has approved three specific oral contraceptives for acne treatment: Ortho Tri-Cyclen, Estrostep, and YAZ. Research indicates that these options are equally effective in treating acne.

Studies show that 50–90% of individuals using oral contraceptives for acne notice an improvement. Results can include a 30–60% reduction in inflammatory acne within 3–6 months, with a meta-analysis of nearly 5,000 patients reporting a 55% reduction in acne lesions after six months.

The type of progestin in the contraceptive also matters. For instance, drospirenone has been shown to be more effective than norgestimate in treating acne. One study highlighted that a combination of drospirenone (3 mg) and ethinyl estradiol (0.02 mg) significantly improved trunk acne after six months of use.

It’s worth mentioning that while noticeable results typically take 3–6 months, some women may experience an initial acne flare-up before seeing improvements. To maximize results, healthcare providers often recommend continuing other acne treatments alongside oral contraceptives.

Reducing Unwanted Hair Growth

Beyond improving skin, oral contraceptives are also effective in managing hirsutism, a condition characterized by excessive hair growth in areas more typical for men, such as the face or chest. Hirsutism affects 5–10% of women of childbearing age, and it’s especially common in those with PCOS, with 70–80% experiencing this symptom.

Oral contraceptives help by suppressing ovulation and reducing androgen production in the ovaries. Additionally, the estrogen in these pills boosts the liver’s production of sex hormone-binding globulin (SHBG), which binds to androgens, reducing their activity.

Results aren’t immediate, as mature hair growth is slow to reverse. However, significant improvements are typically seen after six months of consistent therapy. For example, a combination of drospirenone and ethinyl estradiol has been shown to reduce the Ferriman-Gallwey score - a measure of hair growth severity - by 67% after six months and 78% after a year.

"Drospirenone/ethinyl estradiol combination exerts significant antiandrogenic activity and is effective in improving facial hirsutism. The beneficial effect is most obvious after six cycles and continues thereafter at a slower rate." - ScienceDirect

For women looking for a more comprehensive approach to managing PCOS, telehealth services like Oana Health offer tailored treatment plans. These plans may include oral contraceptives alongside additional therapies like spironolactone or eflornithine, which work together to address hirsutism more effectively.

Healthcare providers generally recommend a minimum of six months of treatment to evaluate how hirsutism responds to oral contraceptives. For optimal results, medical therapy is often paired with cosmetic hair removal methods to manage hormonally driven hair growth.

Risks and Side Effects to Consider

Oral contraceptives can be an effective tool for managing PCOS symptoms, but they come with potential risks. Understanding these side effects and having an open discussion with your healthcare provider is crucial to finding the safest treatment for your needs.

Possible Health Risks

Some common side effects of oral contraceptives include nausea, mood swings, breast tenderness, headaches, spotting, bloating, and weight changes. These often improve within the first few months as your body adjusts to the hormones.

However, there are more serious risks to consider. Oral contraceptives may increase the likelihood of obesity, type 2 diabetes, heart disease, and blood clotting.

• Blood clot risks: The risk of venous thromboembolism (VTE) increases three- to six-fold with oral contraceptives, raising incidents from 5–10 to 8–10 per 10,000 women annually. This risk is especially elevated during the first year of use and among new users. Certain progestin types, like cyproterone acetate, desogestrel, drospirenone, and gestodene, are associated with higher VTE risks compared to levonorgestrel.
• Cardiovascular concerns: Beyond VTE, there’s a 1.6-fold increase in arterial thrombosis risk for women aged 18–50 using oral contraceptives. Unlike VTE, this risk does not decrease over time. Women with PCOS often already face cardiovascular challenges, such as obesity, insulin resistance, high cholesterol, and high blood pressure, which can be exacerbated by oral contraceptives. Additionally, the estrogen component may increase blood pressure by stimulating liver production of angiotensinogen.
• Mental health effects: Some women, particularly younger individuals or those with a history of mental health conditions, may experience mood changes while using oral contraceptives.

Contraindications Table

Given these risks, it’s essential to approach treatment with a personalized plan and regular monitoring.

Finding the Right Treatment for You

To manage these risks, a tailored evaluation is critical before starting treatment. Your healthcare provider will consider factors like age, smoking habits, weight, blood pressure, diabetes risk, and family history of blood clots.

Baseline tests often include blood pressure checks, BMI measurements, and, in some cases, lab tests for glucose tolerance and lipid levels. These assessments help determine whether oral contraceptives are a suitable option for you.

Using the lowest effective dose - typically 20 to 30 μg of ethinyl estradiol (EE) or its equivalent - is recommended to reduce metabolic risks and side effects. Doctors often start with a low-dose formulation and adjust based on your symptoms and how well you tolerate the medication.

Ongoing follow-ups are crucial to monitor your response to treatment and catch any side effects early. Be vigilant about red flag symptoms like leg swelling, severe headaches, vision changes, chest pain, numbness, or muscle weakness, as these require immediate medical attention.

For women with higher risk profiles - such as those with chronic conditions, older age, or preexisting diabetes or hypertension - oral contraceptives may only be considered as a secondary option for managing PCOS. In such cases, alternative treatments may be more appropriate.

Telehealth platforms like Oana Health provide personalized risk assessments and ongoing monitoring, helping ensure your treatment plan adapts to your changing health needs.

Despite the risks, many experts agree that for women with PCOS, the benefits of oral contraceptives often outweigh the potential downsides. The key lies in careful evaluation, open communication with your doctor, and a treatment plan tailored to your unique health profile.

Combining Oral Contraceptives with Other PCOS Treatments

Managing PCOS often requires addressing multiple symptoms at once. While oral contraceptives are highly effective for regulating menstrual cycles and reducing androgen-related concerns like acne and excess hair growth, combining them with other treatments can create a more well-rounded approach to managing this condition. This combination strategy builds on the hormonal balance achieved with oral contraceptives, offering enhanced symptom relief.

Combination Therapies for PCOS

PCOS treatment plans often involve pairing medications to target various symptoms. For instance, metformin is widely used to lower blood sugar levels and improve insulin resistance, which are common issues among people with PCOS. When used alongside oral contraceptives, metformin may also help improve BMI, reduce serum androgen levels, and regulate fasting blood glucose. However, it’s worth noting that metformin can stimulate ovulation, which may increase the likelihood of pregnancy.

Another helpful option is spironolactone, a medication that blocks androgen receptors. This can significantly reduce hirsutism (excess hair growth) and acne. Spironolactone is safe to use with oral contraceptives, but it’s essential to ensure effective contraception while taking it, as spironolactone carries risks during pregnancy.

In addition to medications, lifestyle changes play a critical role in managing PCOS. Even modest weight loss - around 5% of body weight - can lower insulin and androgen levels, amplifying the benefits of medical treatments.

Getting PCOS Care Through Telehealth

Coordinating multiple treatments for PCOS can feel overwhelming, especially when juggling medications, lifestyle changes, and regular doctor visits. Telehealth services have made it easier than ever to access personalized PCOS care, offering a convenient way to manage combination therapies tailored to your specific needs. These platforms allow for comprehensive treatment plans that address multiple symptoms at the same time.

For example, Oana Health specializes in science-backed, personalized PCOS care through telehealth. Their licensed medical providers can prescribe combination therapies, such as oral contraceptives paired with metformin or spironolactone, and deliver these medications straight to your doorstep. Oana Health’s packages are designed to simplify treatment by combining effective medications into a single, manageable plan.

The benefits of telehealth are clear. In 2020, Rachel Blank founded Allara to close gaps in care for women with chronic hormonal conditions like PCOS and endometriosis. Allara’s results speak for themselves: 75% of patients reported symptom improvement within the first two months, and nearly half of overweight or obese patients lost an average of 5% of their body weight within four months. One patient shared:

"The treatment plan for my PCOS has helped me regulate my periods and improve my overall health. I'm very satisfied." – Anna W.

Telehealth offers several advantages, including access to specialists, easy prescription delivery, and consistent monitoring - all without the need for frequent in-person visits. Whether you choose telehealth or traditional care, it’s essential to discuss the benefits, risks, and potential side effects of any combination therapy with your healthcare provider.

Conclusion: Oral Contraceptives for PCOS Management

Oral contraceptives play a critical role in managing PCOS by suppressing luteinizing hormone (LH), reducing ovarian androgen production, and increasing sex hormone-binding globulin (SHBG) to lower free testosterone levels. These hormonal shifts lead to key benefits like more regular menstrual cycles, improved skin clarity, and less unwanted hair growth.

Additionally, oral contraceptives help protect the endometrium, reducing the risk of endometrial cancer. These advantages highlight why they remain a cornerstone of PCOS treatment.

That said, managing PCOS isn’t a one-size-fits-all process. The hormonal and metabolic complexities of this condition call for individualized care tailored to each person’s unique needs.

In this context, personalized telehealth services have emerged as a valuable option. They build on the established benefits of treatments like oral contraceptives while offering convenience and customization. For example, Oana Health provides evidence-based, personalized PCOS treatments prescribed by licensed medical professionals and delivered straight to your doorstep.

Finding the right healthcare provider is essential. As one patient described her telehealth experience:

"This is genuinely the first time in my 7 years of being diagnosed, that I have felt seen and heard." – Lily, Real Allara Member

Whether you opt for traditional in-person care or the flexibility of telehealth, the key is working with a provider who understands the importance of a personalized approach. This is especially true when selecting contraceptives that align with both clinical and metabolic needs. With the right support and a tailored plan, oral contraceptives can be a powerful tool in managing PCOS and improving overall quality of life. Empowering women with options - whether through traditional care or telehealth - ensures they can take control of their PCOS journey effectively.

FAQs

How do birth control pills help with acne and excess hair growth in women with PCOS?

Birth control pills are often used to help women with PCOS tackle issues like acne and excess hair growth. They work by lowering androgen levels - the hormones that play a big role in many PCOS symptoms. With reduced androgens, the skin produces less sebum, which can help prevent clogged pores and breakouts. At the same time, lower androgen levels mean less stimulation of hair follicles, cutting down on unwanted hair growth on the face and body. This dual impact on hormones makes birth control pills a widely used option for managing these PCOS-related concerns.

What are the risks and side effects of using oral contraceptives for PCOS, and how can they be managed?

Oral contraceptives (OCs) are a common choice for managing PCOS symptoms, including irregular menstrual cycles, acne, and excessive hair growth. However, they can come with side effects like slight weight gain, shifts in mood, and, for some women, an elevated risk of blood clots or cardiovascular problems. This risk is particularly relevant for those with pre-existing conditions like high blood pressure or obesity. Additionally, there’s some evidence suggesting that OCs might influence insulin resistance, which is a key concern for women dealing with PCOS.

To reduce potential risks, healthcare providers often pair OCs with lifestyle adjustments, such as adopting a balanced diet and staying physically active. For women who face a higher likelihood of complications, alternatives like progestin-only contraceptives or non-hormonal methods may be recommended. Regular consultations with a healthcare provider are essential to ensure that treatment plans remain safe and specifically tailored to individual needs.

Can oral contraceptives be used alongside other treatments like metformin or lifestyle changes to better manage PCOS symptoms?

Yes, oral contraceptives (OCs) can be paired with other treatments, such as metformin and lifestyle adjustments, to better manage polycystic ovary syndrome (PCOS) symptoms. Studies suggest that combining OCs with metformin is more effective at addressing issues like hirsutism, acne, and insulin resistance compared to using OCs alone. This approach tackles both hormonal imbalances and metabolic challenges, which are central to managing PCOS.

Incorporating lifestyle changes, such as maintaining a balanced diet and staying active, adds even more value. These habits support weight control and boost overall metabolic health, complementing the effects of medication. For many women, a tailored plan that blends OCs, metformin, and healthy lifestyle practices can offer well-rounded relief from PCOS symptoms.
