Disclaimer: This page provides general information about Aczone (dapsone) topical gel for acne. It is not a substitute for professional medical advice. Always consult a healthcare professional for advice tailored to your situation.

What is Aczone?

Aczone is a brand name for a topical gel that contains the active ingredient dapsone. In Canada, this medicine is used on the skin to help treat acne. It is intended for application to the areas of the skin affected by acne and is usually prescribed by a clinician or pharmacist who follows local rules.

The gel is designed to work on the skin where acne develops. It helps reduce redness and swelling and acts locally on the skin. Because it is applied to the skin, most of the medicine is not absorbed into the bloodstream, but some amount may be absorbed, depending on how much is used and where it is applied.

Aczone is intended for topical use only. It should not be put on broken or severely irritated skin, and it should be kept away from the eyes, mouth, and other mucous membranes. It is important to follow the instructions given by your clinician and the product leaflet. If you have questions about whether this medicine is right for you, talk to a pharmacist or doctor.

A general safety note: keep Aczone out of reach of children. Store the product at room temperature away from heat or direct sunlight as directed in the patient information leaflet. If you notice a change in colour, odour, or texture, contact a healthcare professional for guidance before using it again.

What is Aczone used for?

Aczone is used to treat mild to moderate acne on the face and sometimes other areas of the body where acne appears. It is intended to help reduce inflammatory lesions and improve the overall appearance of the skin affected by acne. In Canada, a clinician may determine whether Aczone is appropriate based on your skin condition and medical history.

Because acne can be caused by several factors, Aczone is sometimes used as part of a broader skincare plan. This may include gentle cleansing routines, moisturisers, and other acne therapies prescribed by a clinician. Your healthcare provider will guide you on how to integrate Aczone with any other treatments you are using.

It is important to use Aczone exactly as directed. Do not use more than advised, and avoid applying it to large areas of skin unless your clinician has indicated that is appropriate for you. If your acne changes or worsens, discuss this with your doctor or pharmacist to consider adjustments to your treatment plan.

If you have questions about whether Aczone is suitable for your particular type of acne, or if you have concerns about how it may interact with other skincare products, speak with a pharmacist or clinician. They can help you understand how this medicine fits into your overall plan for managing acne.

How does Aczone work?

Aczone contains dapsone, which has anti-inflammatory properties and antibacterial effects on the skin. By reducing inflammation in the skin and helping to control the bacteria that can contribute to acne, the medicine can help improve the appearance of acne lesions over time.

Because Aczone is applied locally to the skin, most of its action is at the site where it is used. This local action is different from medicines that are taken by mouth or by injection. The exact way in which dapsone helps acne can involve multiple processes, including influencing immune responses in the skin and reducing irritation in affected areas.

As with any topical treatment, the effect may take several weeks to become noticeable. It is common for improvements to occur gradually. Your clinician will explain what you might expect and when to expect it, based on your own skin type and acne pattern.

If you have questions about how Aczone works for you specifically, or if you are using other acne therapies at the same time, talk with your pharmacist or doctor. They can help you understand how these medicines interact and what you might notice in your skin as treatment proceeds.

How to use Aczone

Before applying Aczone, wash your hands and cleanse the skin with a gentle cleanser. Pat the skin dry and wait until it is completely dry before applying the gel. Applying to damp skin can increase or alter the absorption of the medicine.

Apply a thin layer of Aczone to the affected areas of the skin. Avoid applying to healthy skin outside the acne-affected zones unless advised by your clinician. Use only as directed by your healthcare provider or the product leaflet. Do not apply a thicker layer or more frequently in an attempt to speed up results.

Avoid contact with the eyes, mouth, or mucous membranes. If contact occurs, rinse with plenty of water. Do not use Aczone on areas with open wounds or severely irritated skin unless instructed by a clinician. If any irritation or reaction develops, consult your doctor or pharmacist for advice on continuing the treatment or adjusting how it is used.

If you are using other acne products, especially those containing retinoids or benzoyl peroxide, follow your clinician’s guidance on how to space applications. In some cases, these products can irritate the skin more when used together with Aczone. A clinician may suggest applying them at different times of the day or on different days.

If a dose is missed, resume treatment at the next scheduled time as directed by your clinician. Do not double up to make up for a missed application unless advised by a healthcare professional. If you are unsure how to proceed, contact a pharmacist for clarification.

Storage instructions: keep Aczone in its original container, at room temperature, away from heat or direct sunlight. Do not freeze. Keep it out of reach of children and pets. If the product changes colour or texture, do not use it and seek guidance from a pharmacist.

Who should avoid Aczone?

Avoid Aczone if you have a known allergy to dapsone or any ingredient in the gel. If you have had an adverse reaction to similar medicines, discuss this with your clinician before starting Aczone.

People with certain medical conditions should discuss Aczone with a clinician before use. This may include a history of methemoglobinemia, significant anaemia, or a severe immune system condition. If you have a known G6PD deficiency or other blood-related concerns, tell your doctor before using topical dapsone.

If you are pregnant, planning pregnancy, or breastfeeding, talk with your healthcare provider about the risks and benefits of using Aczone. The clinician can help decide whether this medicine fits your pregnancy plan and whether any adjustments are needed for breastfeeding.

A child or adolescent under the age of 12 should not use Aczone unless specifically advised by a clinician. For younger patients, a different acne treatment plan may be appropriate. If you are caring for a child with acne, consult a pediatrician or pharmacist for options.

Warnings and precautions

Tell your clinician about all medicines you use, including vitamins, supplements, and skin products. Some products may interact with Aczone or increase skin irritation when used together. Your clinician can help you assess any potential interactions and adjust your plan accordingly.

Aczone can cause local skin reactions, such as redness, burning, itching, or dryness at the application site. These effects are usually mild to moderate and tend to lessen with continued use. If irritation is severe or persistent, contact a healthcare professional for advice.

Sun exposure or UV light can affect the skin while using acne treatments. Use a broad-spectrum sunscreen, wear protective clothing, and limit intense sun exposure as advised by your clinician. If you notice unusual skin colour changes or persistent irritation, seek medical advice promptly.

If you experience signs of a serious allergic reaction, such as swelling of the face, lips, throat, or trouble breathing, seek urgent medical help immediately. Do not continue using the product in such cases.

Store Aczone away from heat and moisture and keep it out of reach of children. Do not share your medication with others, even if their symptoms appear similar. If you have any questions about storage or safety, ask your pharmacist.

Possible side effects

Common side effects from using Aczone on the skin can include redness, dryness, burning or stinging at the application site, and mild itching. These symptoms often improve with continued use as the skin adjusts to the medicine.

Less common effects may include peeling, flaking, or a sensation of warmth on the skin. Some people may notice temporary changes in skin colour in the treated areas. If these issues persist or become bothersome, consult your clinician.

Very rare but more serious reactions could include severe rashes, blistering, or swelling. If you notice any signs of a severe skin reaction or an allergic reaction, stop using Aczone and seek medical help promptly.

Systemic side effects with topical dapsone are uncommon due to limited absorption through the skin. If you have concerns about potential side effects, or if you are taking other medicines, discuss them with your pharmacist or doctor for personalised guidance.

If you have questions about side effects after starting Aczone, or if side effects affect your daily activities, contact a healthcare professional. They can help determine whether a change in treatment is appropriate for you.

Drug interactions

Because Aczone is applied to the skin, most interactions are unlikely to be strong. However, tell your clinician about all medicines you use, including over-the-counter products and supplements. Some topical products can interact with Aczone to increase skin irritation or affect the skin’s healing process.

If you use other acne medicines, especially topical retinoids or benzoyl peroxide, your clinician may adjust how you use each product. They may recommend spacing applications or altering the frequency of use to reduce irritation and improve tolerance.

Do not start or stop systemic medicines (taken by mouth or by injection) without discussing with your clinician. If you are prescribed a new medicine, inform your doctor that you are using Aczone so they can consider any potential interactions or adjustments to your treatment plan.

Special attention may be needed if you take medicines that can affect the blood or oxygen carrying capacity of the blood, even though Aczone is used topically. If you have concerns about potential interactions with your current medications, ask your pharmacist for a comprehensive review.

Pregnancy and breastfeeding

Information about the safety of Aczone during pregnancy or while breastfeeding is available through healthcare professionals and the product leaflet. If you are pregnant or planning to become pregnant, discuss the benefits and possible risks with your clinician before starting treatment.

If you are breastfeeding, talk with your clinician about whether continuing Aczone is appropriate for you. The decision will consider the balance between benefits to the skin and any potential effects on the infant.

In Canada, the clinician can help determine if Aczone is suitable during pregnancy or while breastfeeding and can advise on any additional monitoring or alternatives if needed.

If you become pregnant while using Aczone, inform your healthcare provider as soon as possible. They can advise whether to continue treatment and whether any adjustments are needed for your skin care routine.

How soon can I expect to see changes after starting Aczone?

Can I wear makeup over Aczone?

Makeup can usually be applied after Aczone has dried, but harsh or irritating products may affect the skin.
