Generic Aczone

Introduction

Aczone is a topical dermatological preparation containing the active compound Diaminodiphenyl Sulfone (commonly known as dapsone). It belongs to the Skin Care medication group and is primarily indicated for the treatment of inflammatory acne vulgaris in adults. In the United Kingdom, Aczone is marketed by Valeant Pharmaceuticals (now Bausch Health) and is prescribed when conventional acne therapies have proved insufficient. The formulation is a 5 % w/w lotion that delivers anti‑inflammatory and antibacterial effects directly to the pilosebaceous unit.

What is Aczone?

Aczone is a brand‑name topical lotion whose sole active ingredient is Diaminodiphenyl Sulfone, a synthetic sulfone with both anti‑bacterial and anti‑inflammatory properties. It was developed in the early 200s to provide a non‑oral option for acne management, reducing systemic exposure compared with oral dapsone. The product is manufactured under strict GMP conditions and approved by the Medicines and Healthcare products Regulatory Agency (MHRA) for use in the UK.

The formulation contains 5 % w/w dapsone in a water‑based lotion, with inactive excipients such as benzyl alcohol, cetyl alcohol, and propylene glycol that aid stability and skin absorption.*

Aczone is the brand name; generic dapsone lotion is also available. Our online pharmacy supplies the generic version at a lower cost while maintaining the same therapeutic concentration of Diaminodiphenyl Sulfone.

How Aczone Works

Diaminodiphenyl Sulfone penetrates the epidermis and reaches the sebaceous glands. Its principal mechanisms are:

• Inhibition of neutrophil chemotaxis – the drug reduces the migration of immune cells that cause the inflammatory papules and pustules characteristic of acne.
• Suppression of bacterial lipopolysaccharide‑induced inflammation – dapsone interferes with the production of pro‑inflammatory cytokines (IL‑1β, TNF‑α) triggered by Cutibacterium acnes.
• Mild antibacterial activity – at the 5 % concentration, dapsone reduces the colonisation of C. acnes without causing the resistance patterns seen with systemic antibiotics.

The combined anti‑inflammatory and antibacterial actions lead to a gradual reduction in acne lesion count. Clinical studies report noticeable improvements after 4–8 weeks of once‑daily application, with maximal effect observed at 12 weeks. The drug is metabolised locally; only a small fraction reaches systemic circulation, limiting systemic side‑effects.

Conditions Treated with Aczone

• Inflammatory Acne Vulgaris (moderate to severe) – the licence in the UK covers use in adults (≥18 years) with inflammatory papules, pustules, and nodules that have not responded adequately to topical retinoids or antibiotics.
• Off‑label use for rosacea‑type papulopustular eruptions – dermatologists sometimes prescribe Aczone for its anti‑inflammatory properties, although this is not an approved indication.

Acne affects up to 30 % of the UK adult population, with a higher prevalence in individuals aged 18–35. Inflammatory lesions are the primary source of scarring and psychosocial impact, making effective topical therapy essential.

Suitable Candidates for Aczone Treatment

• Adults (≥18 years) with moderate to severe inflammatory acne where first‑line agents (benzoyl peroxide, topical retinoids) have been insufficient.
• Patients who prefer a non‑oral regimen to avoid systemic exposure.
• Individuals without a history of G6PD deficiency, as dapsone can precipitate hemolysis in this population.
• Patients not pregnant or breastfeeding, because safety data in these groups are limited.

Contra‑indications include known hypersensitivity to dapsone or any excipient, severe hepatic impairment, and current use of strong oxidising agents that may increase oxidative stress in the skin.

Risks, Side Effects, and Interactions

Common

• Mild skin irritation (erythema, burning, itching) – typically occurs during the first two weeks of treatment.
• Dryness or peeling – use of a non‑comedogenic moisturizer can mitigate this effect.

Rare

• Contact dermatitis – allergic reaction to the lotion base; discontinue use and seek medical advice.
• Hyperpigmentation – especially in individuals with darker skin tones; may improve after cessation.

Serious

• Hemolytic anemia – rare but possible, particularly in patients with glucose‑6‑phosphate dehydrogenase (G6PD) deficiency. Symptoms include fatigue, pallor, dark urine. Immediate medical attention required.
• Methemoglobinemia – an uncommon oxidation of hemoglobin; presents with cyanosis and shortness of breath.

Drug–Drug Interactions

• Systemic dapsone – concurrent oral dapsone can increase the risk of systemic side‑effects.
• Trimethoprim‑sulfamethoxazole and other sulfonamides – may potentiate hemolytic risk.
• Oxidising agents (e.g., high‑dose vitamin C certain topical peroxides) – could exacerbate oxidative stress in the skin.

Patients should disclose all current medications, including over‑the‑counter products and supplements, to their healthcare provider before initiating Aczone.

Practical Use: Dosing, Missed Dose, Overdose

• Standard dosing: Apply a thin layer of Aczone 5 % lotion to the affected area once daily, preferably in the evening after cleansing and before moisturiser. The amount should be enough to cover the lesions without excessive pooling.
• Missed dose: If a dose is forgotten, apply it as soon as remembered unless it is close to the next scheduled application. In that case, skip the missed dose and resume the regular schedule to avoid irritation from double‑dosing.
• Overdose: Excessive topical application is unlikely to cause systemic toxicity, but large amounts applied over extensive skin surface may increase the risk of methemoglobinemia. If significant over‑application occurs, rinse the area with water and seek medical advice promptly.
• Precautions: Avoid applying to broken skin, open wounds, or mucous membranes. Do not combine with other potent topical acne agents (e.g., high‑strength benzoyl peroxide) without professional guidance, as this can accentuate irritation. Alcohol consumption does not affect topical absorption, but patients with hepatic disease should discuss use with a clinician.

FAQ

• Is Aczone available in both brand‑name and generic forms in the UK?
  Yes. Aczone is the branded 5 % dapsone lotion, while generic dapsone lotion contains the same active compound at identical concentration. The generic option is typically more affordable and is supplied by certified manufacturers.

• What is the recommended storage condition for Aczone lotion?
  Store the lotion at room temperature (15‑25 °C) away from direct sunlight, heat, and moisture. Do not refrigerate unless instructed by a pharmacist, as this may alter the lotion’s consistency.

• Can Aczone be used while travelling abroad?
  Yes, the product can be carried in hand luggage provided the container is less than 100 ml and conforms to airline liquid restrictions. Keep the lotion in its original packaging to avoid customs queries.

• Does Aczone contain any allergens that could affect sensitive skin?
  Inactive ingredients include benzyl alcohol and cetyl alcohol, which can cause contact dermatitis in a small subset of individuals. Patients with known sensitivities should review the full excipient list before use.

• How long does it typically take to see an improvement in acne lesions?
  Clinical trials show a noticeable reduction in inflammatory lesions after 4–8 weeks of daily application, with peak efficacy around 12 weeks. Continuity of treatment is essential for sustained results.

• Is there a risk of developing bacterial resistance with Aczone?
  Becauseapsone’s primary action is anti‑inflammatory rather than bactericidal, the risk of resistance is markedly lower than with systemic antibiotics. Nevertheless, alternating or combining with other acne therapies may further minimise any potential resistance.

• Can Aczone be used in combination with oral isotretinoin?
  Concurrent use is generally discouraged due to the increased chance of severe skin irritation and overlapping systemic effects. If combination therapy is required, it should be supervised by a dermatologist.

• What are the legal considerations for importing Aczone for personal use in the UK?
  Personal import of a three‑month supply of a prescription‑only medicine is permissible under the UK’s Medicines (Supply of Unlicensed Medicines) Regulations, provided a valid prescription is held. Import quantities exceeding this limit may be detained by customs.

• Are there any special warnings for patients of Asian descent?
  Some studies suggest a higher prevalence of G6PD deficiency among certain Asian populations, which increases the risk of hemolysis with dapsone. Screening for G6PD deficiency before initiating therapy is advisable.

• Does Aczone have any effect on standard drug‑testing panels?
  Topical dapsone does not normally appear on routine employment or sports drug screens. However, systemic absorption, though minimal, could theoretically be detected in specialized assays for sulfonamide drugs.

• What differentiates the UK formulation from US or Asian versions?
  The UK formulation complies with the MHRA’s specifications for excipients, ensuring the lotion is preservative‑free and alcohol‑free to suit the UK market’s skin‑type preferences. US versions may contain additional stabilisers, while some Asian products use a cream base instead of a lotion.

• Can Aczone be safely used on the face and neck simultaneously?
  Yes, the lotion can be applied to any affected area, including the face, neck, chest, and back, as long as the skin is intact. Avoid excessive layering on the same spot to reduce irritation risk.
