What I need to know about oral Spironolactone:
Spironolactone is primarily a medication used to treat conditions like high blood pressure and fluid retention (edema) due to its anti-androgenic effects. Oral Spironolactone is sometimes used off-label as a treatment for hair loss in certain individuals, particularly in women who have a condition called androgenetic alopecia (female pattern hair loss) or other hair loss conditions with an androgenic component. While you are taking this medication, you should be cautious of foods that are known to have high potassium levels.
Absolute Contraindications – DO NOT use oral Spironolactone if you:
- Are allergic to oral Spironolactone
- Are under 18 or are pregnant, breastfeeding, or planning to become pregnant
- Have a history of cancer, heart failure, kidney problems or liver problems
- Have any present or past issues with hyperkalemia, Addison's disease (chronic adrenal insufficiency), or other conditions associated with hyperkalemia and/or are receiving other potassium-sparing agents.
Drug Interactions – DO NOT use oral Spironolactone if you take:
- ACE inhibitors
- angiotensin receptor blockers
- Potassium channel blockers or medications for hyperkalemia
- Non-steroidal anti-inflammatory drugs (NSAIDs)
- Diuretics
- Trimethoprim
- Lithium
- Cholestyramine
- Abiraterone
- Digoxin
- Eplerenone
- Certain hepatic/ liver medications or medications for Addison’s disease (see a doctor in-person about seeking treatment with oral Spironolactone)
Serious Side Effects – STOP treatment and seek emergency medical care or call 911 if you experience:
- Hypotension
- Worsening of renal (kidney) or hepatic (liver) function
- Digestive abnormalities including bleeding and vomiting
- Electrolyte and metabolic abnormalities
- Feeling faint, shortness of breath, or difficulty breathing
- Increase in potassium (hyperkalemia)
- Gynecomastia/breast tenderness/increase in breast size
- Impaired neurological function

It’s important to closely and regularly monitor for these side effects while taking oral spironolactone, especially when starting or changing your dose, as they can indicate a severe reaction. If you notice any side effects, stop taking oral spironolactone and seek immediate medical attention, or call 911.
Common Side Effects – Talk to your provider about changing your dose/treatment if you experience:
- Headache
- Increased urination
- Insomnia or changes in energy levels
- Nausea
- Changes in libido and menstrual cycle (e.g. irregular or absence of periods)
- Hair shedding: It's common to experience increased hair shedding initially. This is typically a temporary phase as hair follicles regenerate.
- Some may also experience changes in hair texture and color.
These are not all the possible side effects of oral Spironolactone. For more information, ask your healthcare provider or pharmacist and refer to the full prescribing information.
SERIOUS WARNINGS:
- PREGNANCY RISK : Spironolactone may cause birth defects based on its mechanism and animal studies. Pregnant women and women who plan to become pregnant in the near future, should not take spironolactone under any circumstances.
- INFERTILITY RISK: Spironolactone may cause an increased risk of infertility, breast tenderness/increase in breast size, irregular periods, or lack of menstrual periods. If you notice these symptoms, seek immediate emergency medical care.
- CANCER RISK: Spironolactone may cause an increased risk of certain types of cancer. During animal testing, spironolactone caused tumor growth in specific rats. Although animal findings don't always reflect human responses, Tangl dermatologists adhere to a principle of caution when prescribing. Due to its potential carcinogenic implications, you should not use oral Spironolactone if you have a history or risk of cancer. If you notice any unusual symptoms, seek immediate emergency medical care.
Always use Oral Spironolactone under the supervision of a healthcare professional and undergo regular medical assessments during treatment.
Always Inform Medical Professionals: Always consult a healthcare provider immediately about any unusual side effects, concerns or changes noticed during treatment. You can message your Tangl dermatologist through your Tangl account (trytangl.com/account) if you have any questions or concerns about your treatment.
Always Provide Accurate Health Information: Failing to provide accurate information about your health and medical history can lead to severe consequences, including harm or, in some instances, death.
Report Side Effects to the FDA: Negative side effects should be reported to the FDA at www.fda.gov/medwatch or call 1-800-FDA-1088.

*Prescription-only. Medical form provided after checkout must be completed for dermatologist review.

Spironolactone is an oral medication primarily known to block the effects of male hormones called androgens, including DHT (dihydrotestosterone), a hormone responsible for hair loss. These hormones play roles in hair growth, oil production in the skin, and other processes. While spironolactone is frequently used for treating acne and excessive facial hair growth, it is also used in addressing female pattern hair loss (AGA).
Spironolactone (50mg): An FDA-approved oral medication initially intended for managing fluid retention and high blood pressure, now finds a new purpose off-label in the fight against hair loss. Its key strength lies in its ability to block androgens, including DHT (dihydrotestosterone), a hormone responsible for hair loss. These actions directly influence the health of hair follicles, making it a potent tool for combatting hair loss in women.
Take one capsule by mouth once per day.*
