Spironolactone is widely used to treat conditions like PCOS, acne, and excess hair growth by managing androgen levels. However, because it affects hormones, kidneys, and electrolytes, regular lab tests are critical to ensure safe and effective treatment. Here's what you need to know:
-
Key Lab Tests:
- Hormone levels: Total and free testosterone, DHEA-S
- Electrolytes: Potassium, sodium (to monitor risks like hyperkalemia)
- Kidney function: Creatinine, BUN, eGFR
-
Testing Schedule:
- Baseline tests before starting treatment
- Frequent checks in the first 3 months (2–3 days, 7 days, monthly)
- Every 3 months afterward if stable
-
Normal Ranges:
- Potassium: 3.5–5.0 mEq/L (above 5.5 mEq/L is dangerous)
- Creatinine: 0.6–1.1 mg/dL (women)
- Free testosterone: 0.3–3.2 pg/mL
Regular monitoring helps adjust doses, catch side effects early, and track progress. Telehealth platforms simplify this process by offering online lab test orders, quick results, and personalized care, making spironolactone therapy more accessible and manageable.

Key Lab Tests for Androgen Monitoring
Tracking androgen levels is crucial for evaluating treatment effectiveness and ensuring safety. To achieve this, healthcare providers rely on specific lab tests that focus on hormones, electrolytes, and kidney function. These tests fall into three main categories, each playing a vital role in monitoring progress and maintaining safety.
Androgen Level Tests: Testosterone and DHEA-S
Total and free testosterone levels are key indicators of how spironolactone reduces androgen activity. Total testosterone measures both bound and unbound forms of the hormone, while free testosterone reflects the active portion responsible for symptoms.
Another important marker is DHEA-S (dehydroepiandrosterone sulfate), a hormone largely produced by the adrenal glands. Elevated DHEA-S levels are common in conditions like PCOS and other forms of androgen excess. Monitoring this hormone helps determine whether spironolactone is addressing the root causes of symptoms effectively.
Hormone levels often improve within 3–6 months of treatment, though the timeline can vary depending on factors like dosage, baseline hormone levels, and the underlying condition. By comparing current results to baseline measurements, providers can gauge the treatment's effectiveness.
Monitoring Potassium and Electrolyte Levels
One of the primary safety concerns with spironolactone is hyperkalemia, or elevated potassium levels. This occurs because spironolactone blocks aldosterone receptors, reducing the kidneys' ability to excrete potassium, which can lead to dangerous buildups.
To establish a baseline, providers order a Basic Metabolic Panel (BMP) before starting treatment. This test measures potassium, sodium, chloride, and other electrolytes.
Electrolyte levels are closely monitored, starting 2–3 days after treatment begins or after dose adjustments, then again at 7 days, and monthly for the first three months.
- Normal potassium levels range from 3.5 to 5.0 mEq/L. Levels exceeding 5.5 mEq/L require immediate intervention, which may include lowering the dose or discontinuing treatment.
- Sodium levels are also monitored, as spironolactone can disrupt the balance between sodium and potassium.
Kidney Function Tests: BUN and Creatinine
Since the kidneys play a central role in processing spironolactone and regulating electrolytes, kidney function tests are essential throughout treatment. Two key tests assess kidney health:
- Creatinine levels: Creatinine is a waste product filtered by healthy kidneys. Elevated levels may signal reduced kidney function, which can impact how spironolactone is processed. Providers also calculate the estimated glomerular filtration rate (eGFR) using creatinine levels, age, and other factors.
- BUN (blood urea nitrogen): This test measures how effectively the kidneys remove urea, another waste product. The BUN-to-creatinine ratio can help identify specific kidney issues and guide treatment decisions.
The FDA advises periodic monitoring of renal function, serum electrolytes, uric acid, and blood glucose during treatment. This approach ensures that spironolactone does not adversely affect kidney health or overall metabolic function.
After the initial three months of frequent monitoring, tests are typically conducted every three months if results remain stable. However, more frequent testing may be necessary for patients with pre-existing kidney issues, those taking medications that impact kidney function, or those showing symptoms of electrolyte imbalances.
These lab tests provide critical data for adjusting doses and ensuring long-term safety during treatment.
Lab Monitoring Schedule and Best Practices
Getting baseline lab tests done is a key step to ensure safety and keep track of how well your treatment is working.
Baseline Lab Tests Before Starting Spironolactone
Before starting spironolactone, your healthcare provider will order several baseline tests, including:
- Kidney Function and Electrolytes: These tests measure serum creatinine, estimated glomerular filtration rate (eGFR), blood urea nitrogen (BUN), potassium, and sodium levels. If your potassium level is above 5.0 mmol/L or creatinine exceeds 2.5 mg/dL, treatment may not be initiated.
- Pregnancy Test: This is required for women who could become pregnant, as spironolactone can affect fetal development.
"Monitoring before starting spironolactone for hormonal acne should include baseline blood tests for potassium, sodium, and kidney function (BUN and creatinine) in patients with risk factors for hyperkalemia, such as older age, medical comorbidities, or medications that affect renal function, as recommended by the most recent guidelines. A pregnancy test is essential for women of childbearing potential, as spironolactone can cause feminization of male fetuses."
– Dr.Oracle Medical Advisory Board & Editors
In addition to these tests, your provider will check your blood pressure and may order hormone tests, such as DHEA-S and free testosterone, if you have symptoms linked to androgen levels.
Once these baseline values are established, your provider will create a follow-up plan tailored to your needs.
Follow-Up Monitoring
Using the baseline results as a starting point, follow-up tests are scheduled based on your individual risk factors. Regular monitoring helps ensure that the treatment remains safe and effective.
Be sure to stick to your healthcare provider's recommendations for lab tests and follow-up visits. These check-ins are essential for fine-tuning your treatment plan to best suit your health and progress.

Understanding and Reading Lab Results
Being able to interpret lab results is a valuable tool for tracking your progress and making informed treatment decisions.
Normal vs. Abnormal Lab Values
Lab results include reference ranges that define what’s considered normal for each test. These ranges can vary slightly between labs, but when you're on spironolactone, there are specific values to keep an eye on for safety and effectiveness.
- Potassium levels: These should remain between 3.5 and 5.0 mEq/L. Levels above 5.0 mEq/L signal hyperkalemia, a potentially dangerous condition that requires immediate attention.
- Kidney function markers: These include creatinine and blood urea nitrogen (BUN). For women, normal creatinine levels range from 0.6 to 1.1 mg/dL, while BUN levels should fall between 7 and 20 mg/dL. The estimated glomerular filtration rate (eGFR) should be over 60 mL/min/1.73m² to indicate healthy kidney function.
- Androgen levels: These vary more widely but typically show improvement over time with treatment. Normal free testosterone levels for women range from 0.3 to 3.2 pg/mL, while DHEA-S levels can range from 35 to 430 μg/dL, depending on age.
Lab reports flag results outside the normal range, but slight deviations don’t always indicate a problem. Your healthcare provider will interpret these numbers in the context of your overall health and symptoms. If any abnormal values appear, the next step is addressing them to ensure your safety.
Actions for Abnormal Results
When lab results fall outside normal ranges, your healthcare provider will decide on the best course of action based on the severity of the results and your specific situation.
- High potassium levels: Elevated potassium is the most serious concern with spironolactone. If levels are too high, your provider may reduce your dose or pause treatment. You might also need to avoid potassium-rich foods and undergo more frequent monitoring until levels return to normal.
- Changes in kidney function: A slight increase in creatinine might only require closer monitoring, but a significant rise could mean adjusting your dose or exploring alternative treatments.
- Androgen level shifts: Gradual changes in androgen levels usually indicate that the treatment is working. However, if there’s no improvement after 6 to 12 months, your doctor might consider increasing your dose.
Sometimes abnormal results are temporary, caused by factors like dehydration, illness, or other medications. In such cases, your healthcare provider may recommend retesting in a few weeks to confirm whether the values persist. These follow-ups are key to ensuring your treatment stays on track.
Using Lab Results to Track Progress
Lab results provide objective data to assess how well your spironolactone treatment is working. Instead of focusing on single test results, look at long-term trends to guide adjustments, as hormonal changes often take time.
- Androgen level improvements: These typically show up in lab results before you notice physical changes like reduced acne or hair growth. Gradual improvements in these markers confirm that the treatment is effective, even if visible results take longer.
- Stable kidney and electrolyte levels: Consistently normal readings over multiple tests indicate that your body is tolerating the medication well. This stability allows your provider to maintain your current dose while fine-tuning other aspects of your treatment.
Your healthcare provider may use a tracking chart or digital tools to monitor your progress over time. These tools help identify trends and guide dose adjustments.
Combining lab results with symptom tracking provides a fuller picture of your progress. For example, while testosterone levels might improve, monitoring symptoms like acne severity or hair growth can help confirm whether these changes are making a noticeable difference.
Regular lab monitoring also plays a role in finding the right maintenance dose once your symptoms improve. Some women can lower their spironolactone dose while still maintaining its benefits, and lab results are essential for ensuring these adjustments are made safely.
