Generic Aczone Information

Introduction

Aczone ® is a topical dermatological preparation indicated primarily for the treatment of inflammatory acne vulgaris. It contains the active compound diaminodiphenyl sulfone (commonly known as dapsone) at a concentration of 7.5 % in a non‑aqueous gel base. In Hong Kong, Aczone is classified as a prescription‑only skin‑care medication and is supplied by Galderma, a global dermatology company. The gel is also used off‑label for certain inflammatory dermatoses such as rosacea and hidradenitis suppurativa when conventional therapies are inadequate.

What is Aczone?

Aczone is a prescription‑only topical gel that delivers diaminodiphenyl sulfon e (dapsone) directly to the skin.

• Classification: Antiinflammatory and antibacterial topical agent (Skin Care).
• Development: Dapsone was originally introduced as an oral antimicrobial for leprosy; the 7.5 % gel formulation was developed to exploit its anti‑inflammatory properties while minimizing systemic absorption.
• Manufacturer: Galderma (Switzerland), marketed globally under the Aczone brand name.

The gel is packaged in a pump‑dispensed tube of 30 g or 60 g, each unit containing a shelf‑life of 24 months when stored under recommended conditions.

How Aczone Works

Dapsone exerts its therapeutic effect through two principal mechanisms:

1. Anti‑inflammatory action: Dapsone inhibits neutrophil chemotaxis and reduces the release of reactive oxygen species. By limiting the migration of inflammatory cells into the pilosebaceous unit, it lowers the formation of inflammatory papules and pustules.
2. Antimicrobial activity: Dapsone interferes with bacterial folic‑acid synthesis, providing modest activity against Cutibacterium acnes (formerly Propionibacterium acnes).

When applied topically, only a small fraction enters systemic circulation (plasma concentrations < .5 µg/mL), which accounts for the relatively low risk of systemic adverse effects. The gel’s non‑aqueous vehicle enhances dermal penetration and ensures a steady release of the active compound over several hours, resulting in an onset of visible improvement within 2–4 weeks of consistent use.

Conditions Treated with Aczone

• Mild‑to‑moderate inflammatory acne vulgaris (Papules, pustules, and early nodules).
• Rosacea with papulopustular component – used off‑label where oral tetracyclines are contraindicated.
• Hidradenitis suppurativa (Stage I‑II) – as adjunctive therapy for localized lesions.

In Hong Kong, acne prevalence among adolescents and young adults is estimated at 15‑20 % (Hong Kong Dermatology Society). Aczone’s targeted anti‑inflammatory action makes it a valuable option for patients who have not responded adequately to topical retinoids or benzoyl peroxide.

Patient Groups Most Likely to Benefit

• Individuals with inflammatory acne who prefer a non‑antibiotic topical option, reducing the risk of antibiotic resistance.
• Patients with skin of colour who are prone to post‑inflammatory hyperpigmentation; Aczone’s low irritation profile helps minimize pigmentary sequelae.
• Adults with contraindications to oral antibiotics (e.g., pregnancy, lactation, hepatic disease).

Aczone is not appropriate for:

• Non‑inflammatory comedonal acne as monotherapy.
• Patients with known hypersensitivity to dapsone or sulfone derivatives.
• Individuals with glucose‑6‑phosphate dehydrogenase (G6PD) deficiency when systemic absorption is anticipated (rare in topical use, but caution is advised).

Risks, Side Effects, and Interactions

Common

• Mild skin irritation (stinging, burning, erythema).
• Dryness or peeling at the application site.
• Transient hyperpigmentation, especially in darker skin types.

Rare

• Contact dermatitis with eosinophilia.
• Localized pustular or pustular‑type eruptions resembling an allergic reaction.
• Systemic absorption leading to mild hemolysis in G6PD‑deficient individuals (extremely uncommon with topical use).

Serious

• Methemoglobinemia: Rare but documented cases with prolonged high‑dose topical use; presents with cyanosis and dyspnea.
• Severe hemolytic anemia: More likely with oral dapsone; topical cases are exceedingly rare but require immediate medical evaluation.

Drug–Drug Interactions

• Concurrent use of other topical oxidizing agents (e.g., benzoyl peroxide) may increase local irritation.
• Systemic dapsone or sulfone antibiotics can compound the risk of hemolysis and methemoglobinemia; clinicians should review the full medication list before prescribing Aczone.

Patients should avoid applying Aczone to broken skin, open wounds, or mucous membranes to reduce systemic exposure.

Practical Use: Dosing, Missed Dose, Overdose

• Standard dosing: Apply a thin layer (approximately a pea‑size amount) to the affected face once daily in the evening after cleansing and drying.
• Missed dose: Apply the missed dose as soon as remembered, unless it is close to the time of the next scheduled dose; in that case, skip the missed dose and resume the regular schedule.
• Overdose: In the unlikely event of extensive topical application, monitor for signs of systemic toxicity (e.g., dyspnea, cyanosis, hemolysis). Seek immediate medical attention; treatment is supportive, with possible administration of methylene blue for methemoglobinemia.

Precautions

• Do not use with other strong acne‑treatment agents (e.g., oral isotretinoin) without physician guidance.
• Avoid excessive sun exposure; use sunscreen to prevent photo‑induced hyperpigmentation.
• Alcohol consumption does not directly affect topical Aczone but may aggravate skin dryness.

FAQ

• Is Aczone covered by the Hospital Authority’s drug formulary in Hong Kong?
  No, Aczone is not listed in the public hospital formulary and is typically obtained via private dermatology prescriptions or licensed pharmacies.

• Can Aczone be used concurrently with topical retinoids?
  Yes, clinicians sometimes prescribe Aczone alongside retinoids on alternate nights to balance efficacy and skin tolerability, but close monitoring for irritation is advised.

• What is the difference between Aczone and oral dapsone tablets?
  Oral dapsone provides systemic antimicrobial and anti‑inflammatory effects, carrying higher risks of hemolysis and methemoglobinemia. The topical gel delivers the drug locally, drastically reducing systemic exposure and associated adverse events.

• Does Aczone require refrigeration or any special storage conditions?
  No, Aczone should be stored at controlled room temperature (15‑30 °C), protected from direct sunlight and moisture. Refrigeration is unnecessary and may affect gel consistency.

• How many units of Aczone can I import for personal use in Hong Kong?
  Personal importation of prescription medicines is permitted for up to a 30‑day supply per individual, provided a valid prescription is presented. Our online pharmacy assists in complying with these limits.

• Are there any known differences in formulation between the EU and US versions of Aczone?
  Both regions market a 7.5 % dapsone gel with identical inactive ingredients; minor packaging variations exist, but the clinical composition remains the same.

• Can Aczone be prescribed through tele‑dermatology services?
  Yes, many Hong Kong tele‑medicine platforms allow board‑certified dermatologists to issue electronic prescriptions for Aczone, which can then be fulfilled through our online pharmacy.

• What should I do if I experience a rash after starting Aczone?
  Discontinue use immediately and contact your dermatologist. A mild localized rash may resolve with temporary cessation, whereas a spreading or severe reaction requires medical evaluation.

• Is Aczone safe for use during pregnancy or lactation?
  Topical dapsone is classified as pregnancy category B (no evidence of risk in animal studies). However, physicians typically weigh benefits against potential risks, especially in the first trimester. Use only under obstetric guidance.

• How long does it typically take to see clinical improvement with Aczone?
  Most patients notice a reduction in inflammatory lesions within 2–4 weeks, with maximal benefit observed after 8–12 weeks of consistent daily use.

• Does my health insurance in Hong Kong reimburse Aczone?
  Private health insurers may provide partial reimbursement if a specialist’s prescription is submitted. Coverage varies; patients should verify benefits with their insurer.

• Can Aczone be used on body sites other than the face?
  Off‑label use on the chest, back, or shoulders is sometimes practiced for acne lesions, but the gel’s adherence may be reduced on heavily hairy areas. Discuss site‑specific application with your dermatologist.
