Duac is a combination medication used to treat inflammatory acne. Duac is a combination of clindamycin, which is an antibacterial antibiotic that helps to fight infection. Duac also contains benzoyl peroxide, an anti-inflammatory that also exfoliates skin and destroys the bacteria that clog pores. Using a combination of these two medications helps to decrease the number of pimples and evens out skin tone.


  • How Does Duac Work?

    Duac works in two ways. As an antibacterial with the antibiotic clindamycin, Duac works to kill bacteria that contribute to acne, although clindamycin doesn't work to physically clean pores. That's where benzoyl peroxide comes in. Benzoyl peroxide works as an exfoliant and removes sebum (oil) and dead skin cells to double the fight against acne-causing bacteria.

    Apply a thin layer of Duac to affected areas according to product directions. It may take up to six weeks to see a decrease in acne and up to 12 weeks to see the full benefits.

  • Where Can You Get Duac?

    Duac is available by prescription.

  • Are There Any Precautions?

    When using this product, avoid getting it in the eyes, mouth, or inside the nose. Avoid applying to areas of broken skin or skin that has been windburned or sunburned. Wash your hands after using Duac and avoid contact with hair or clothing as it can cause bleaching. Avoid using this product more often than directed, your condition will not improve faster and you increase the risk of side effects.

    This drug can be passed into breast milk, so consult your doctor before breastfeeding or before using Duac.

  • Are There Any Side Effects?

    • Dry skin
    • Redness
    • Burning
    • Itching
    • Peeling

    These common side effects might last for the first few days or weeks while your skin is adjusting to the medication. Use sunblock liberally and apply moisturizer to help combat the drying effects of Duac.

    Uncommon side effects include diarrhea, abdominal or stomach pain, cramping, or blood in the stool. Serious allergic reactions, although rare, can include itching, swelling, dizziness, and trouble breathing. If you experience any symptoms other than common side effects, see your doctor.

  • What Else Should You Know About Duac?

    Avoid using Duac in combination with erythromycin. Erythromycin, also an antibiotic, and clindamycin have been known to clash, and overuse of antibiotics can be dangerous and worsen side effects. Avoid using Duac if you are taking any neuromuscular blocking agents as Duac can enhance their action.

  • How Should Duac Be Stored?

    Duac gel should be stored in the refrigerator, but do not freeze it. In order to maintain its structural integrity and efficacy don't leave it in a car or on a windowsill where sunlight could reach it.

  • Should I Use a Moisturizer Over Duac?

    Absolutely. It's best to use sunblock during the day to protect skin from photosensitivity while using a moisturizer at night after you've applied a layer of Duac.

  • How Long Should I Use Duac?

    You will probably be prescribed Duac for a six to 12-week cycle. After that, your doctor will determine whether or not to continue using Duac or switch to another medication.

  • Is It Safe to Use Duac While Pregnant?

    Using this medication while pregnant is something that you should discuss with your doctor. Because the antibiotic in Duac might leach into breast milk or otherwise affect the pregnancy, it's best to explore your options for acne medications that work best for you.
