Can Spironolactone Cause Yeast Infections? The Risks

Understanding Yeast Infections and Their Causes

Yeast infections are uncomfortable fungal infections typically caused by an overgrowth of the fungus Candida albicans. While yeast naturally lives in our bodies, certain factors can trigger an overgrowth causing infection and inflammation. Some of the most common symptoms include itching, burning, redness, and thick cottage cheese-like discharge.

Medications are one potential cause of yeast infections. The antibiotics, oral contraceptives, and corticosteroids often prescribed to treat various conditions can disrupt the natural bacterial balance in our bodies, allowing yeast to overgrow. But could the medication spironolactone also be leading to increased yeast infections for some patients?

What is Spironolactone?

Spironolactone is a medication used to treat several conditions related to fluid retention and high blood pressure. It’s a potassium-sparing diuretic that helps the body remove excess fluid and sodium by increasing urine output. It's also used to treat acne and hair loss in some women due to its anti-androgen effects.

Why Spironolactone May Contribute to Infections

There are a few reasons why spironolactone could potentially increase someone's risk of developing yeast infections:

• It changes hormone levels. Spironolactone blocks androgens like testosterone. This hormone shift could allow more Candida growth.
• It’s immunosuppressive. Spironolactone may slightly suppress the immune system, making it harder to keep yeast under control.
• It causes potassium retention. Some research shows Candida albicans prefers a high-potassium environment.

Studies Investigating the Link

So far, there’s limited research specifically on spironolactone and yeast infections. But a handful of small studies provide some insight:

• A 2013 case report described recurrent vaginal infections in a patient after starting spironolactone. Her infections continued until she stopped the medication.
• A 2018 literature review found several cases linking spironolactone to recurrent yeast infections and advised monitoring patients on it.
• A 2022 study saw more yeast isolation from the vaginal wall in women taking spironolactone versus other medications.

While more research is still needed, these early findings suggest spironolactone could increase susceptibility to yeast overgrowth and infection for some patients.

Who May Be at Risk?

Based on current evidence, the following patients on spironolactone may have increased risk of developing yeast infections:

Those with recurrent infections

If you already get frequent yeast infections, starting spironolactone could make them happen more often or worsen symptoms. The medication may disrupt your body's natural defenses against Candida overgrowth.

People with weakened immune systems

Those with weakened or impaired immune systems due to health conditions are more prone to infections in general. Spironolactone’s immunosuppressive effects, while mild, could further reduce the body’s ability to regulate yeast growth.

Diabetic patients

Uncontrolled blood sugar levels make it easier for yeast to grow out of control. Spironolactone could stack the odds against diabetic patients who already tend to get more vaginal infections.

Can Anything Be Done to Prevent Infections?

If you’re at higher risk for yeast infections while taking spironolactone, there are some things you can try to help avoid them:

Maintain healthy blood sugar

Careful blood sugar management is key for diabetics on spironolactone. Work closely with your doctor, monitor levels diligently, and stick to your prescribed treatment plan.

Improve gut health

Boosting beneficial gut bacteria through probiotic foods or supplements may strengthen your microbiome resilience against yeast overgrowth.

Practice good hygiene

Regularly cleaning the vaginal area and wearing breathable cotton underwear can help prevent the warm, moist environment yeast thrives in.

Ask about medication changes

If infections persist despite preventive steps, talk to your doctor about alternative medication options to spironolactone that may be less likely to disrupt yeast growth.

Getting Treatment for Infections

If you do develop a yeast infection while on spironolactone, there are effective treatments available, including:

Over-the-counter antifungals

Creams, ointments, suppositories, and other products containing miconazole or clotrimazole can be purchased without a prescription to treat mild infections.

Prescription antifungals

Oral fluconazole or various topical azole formulations may be prescribed for more severe infections. These halt fungal growth and clear symptoms faster.

Boric acid suppositories

Some women report relief from inserting these acidic capsules vaginally 1-2 times per day until the infection resolves.

Probiotics

Oral probiotics or vaginal probiotic suppositories may help restore normal vaginal bacteria levels to prevent recurrence.

Make sure to finish the full antifungal treatment course. You should also schedule a follow-up appointment with your doctor to confirm the infection cleared and rule out other potential causes like STIs.

The Bottom Line

The diuretic spironolactone does appear to increase the risk of yeast infections for some patients based on initial research. Women prone to Candida overgrowth may experience more frequent or persistent infections while taking the medication.

Those at higher risk should take preventive steps like maintaining good blood sugar control and may need to switch medications if problems continue. If you develop an infection on spironolactone, over-the-counter or prescription antifungals usually provide effective symptom relief.
