Spironolactone 5% | Tea Tree Oil 5%

Route: Topical application to acne-affected facial or body skin.

• Cleanse and pat skin dry before application.
• Apply a thin layer to affected area(s) once or twice daily per prescriber instruction.
• Avoid contact with eyes, mucous membranes, and open wounds.
• Wash hands after applying.
• Allow the preparation to absorb before applying other topical products.

Applied topically once or twice daily to acne-affected areas as directed by the prescriber. Frequency and duration are individualized. Full assessment of therapeutic response requires at least 8–12 weeks of consistent use.

• Spironolactone (topical): Competes with testosterone and DHT for androgen receptor binding in sebaceous gland cells; also inhibits type 1 and type 2 5α-reductase, limiting local conversion of testosterone to the more potent DHT; may upregulate SHBG expression. Result: reduced sebum secretion, decreased follicular hyperkeratinization, and fewer androgen-driven acne lesions—with minimal systemic hormonal effects at topical 5% concentration.
• Tea Tree Oil (terpinen-4-ol): Intercalates into bacterial cell membranes, disrupting bilayer integrity, causing cytoplasmic leakage, and inhibiting cellular respiration. Also modulates inflammatory pathways by attenuating histamine-induced vasodilation and reducing inflammatory cytokine release. Active against Cutibacterium acnes at concentrations well below 5%.

Indication context: Indicated for hormonal and mild-to-moderate inflammatory acne vulgaris, particularly in patients where androgenic sebum overproduction is a primary driver. May be used as monotherapy in mild cases or as adjunct to systemic or topical retinoid therapy. Suitable for patients in whom systemic antiandrogens (e.g., oral spironolactone) are not preferred or tolerated.

Monitoring:

• Evaluate lesion counts at 8–12 weeks; assess sebum reduction and comedone response.
• Monitor for skin irritation or contact sensitization to tea tree oil.
• No routine labs required for topical use; systemic potassium effects are not expected at 5% topical spironolactone concentrations.

Contraindications:

• Hypersensitivity to spironolactone, tea tree oil (Melaleuca alternifolia), or any excipient.
• Avoid on open wounds, mucous membranes, or periocular areas.

Warnings & Precautions:

• Tea tree oil: rare cases of contact allergic dermatitis; discontinue if rash or hypersensitivity develops.
• Pregnancy: although systemic absorption is low, the antiandrogenic potential of spironolactone warrants caution; use only under prescriber direction.
• Keep out of eyes; rinse thoroughly with water if ocular contact occurs.

Drug Interactions:

• Systemic interactions are unlikely at topical concentrations; no clinically significant interactions identified for topical spironolactone or tea tree oil at these doses.

Common Side Effects: Local dryness, mild erythema, or skin scaling; rarely, contact dermatitis from tea tree oil sensitization.

Store at room temperature (15–25°C). Protect from direct light and excessive heat. Keep container tightly closed; tea tree oil is volatile. Do not freeze. Use within the beyond-use date assigned by Genesis Compounding per USP <795> standards. Keep out of reach of children.

How does this differ from the three-ingredient spironolactone/dapsone/tea tree oil formula?

This two-ingredient preparation omits dapsone. It is selected when the prescriber determines that the anti-inflammatory and antimicrobial activity of tea tree oil alone is sufficient, or when dapsone is contraindicated (e.g., sulfonamide allergy, G6PD deficiency concern, or patient preference).

Can this be used in male patients?

Topical spironolactone at 5% works locally on sebaceous glands and has minimal systemic hormonal effects. Male patients may use it without the systemic endocrine effects associated with oral spironolactone; however, prescriber judgment on individual suitability is required.

When will I see results?

Most topical acne therapies require 8–12 weeks of consistent daily use before meaningful lesion count reduction is observed. Do not discontinue prematurely. Report treatment response at scheduled follow-up visits.

Is this preparation FDA-approved?

There is no FDA-approved topical spironolactone product. Tea tree oil preparations are available OTC. This two-ingredient combination is a patient-specific 503A compounded preparation from Genesis Compounding, available only with a valid prescriber order.
