In the U.S., the documented prescription triple-combination acne gel is Cabtreo. It combines three active ingredients—clindamycin, adapalene, and benzoyl peroxide—in one once-daily treatment. The American Academy of Dermatology distinguishes Cabtreo from two-drug products such as Epiduo and Twyneo. Its main advantage is combination therapy in one product, but the evidence does not prove it outperforms every acne regimen.

What is in the three-drug gel?
Cabtreo contains clindamycin phosphate 1.2%, adapalene 0.15%, and benzoyl peroxide 3.1%. The DailyMed prescribing information lists it for topical acne treatment in adults and children aged 12 or older. Clindamycin is a topical antibiotic, while adapalene is a retinoid.
Benzoyl peroxide adds another mechanism and helps address the resistance concern created by antibiotic use. This design follows AAD guidance favoring treatments with different mechanisms. The guidance also recommends pairing topical antibiotics with benzoyl peroxide to help prevent antibiotic resistance.
How well does Cabtreo work?
Two randomized, vehicle-controlled trials followed 363 participants for 12 weeks. treatment success required clear or almost-clear skin plus at least a two-grade improvement in acne severity. Cabtreo met that standard in 49.6% and 50.5% of users across the two trials.
Vehicle gel produced success rates of 24.9% and 20.5%. A pooled Phase 3 analysis reported 50.0% treatment success with Cabtreo versus 22.6% with vehicle. Inflammatory lesions fell by 77.9%, while noninflammatory lesions fell by 73.0%.
What the evidence cannot tell you
The trial results show that the full formulation works better than inactive vehicle gel over 12 weeks. They do not establish that it is superior to every separate-product combination or other practical acne regimen. The CADTH clinical review also notes that most trial participants had moderate rather than severe acne.
evidence for long-term outcomes and for people with severe acne is therefore more limited. The results are most directly useful to someone whose acne resembles the studied population. Treatment choice still depends on factors the trials did not compare, including whether a person can tolerate all three ingredients.
How should the gel be used?
Apply a thin layer once daily after gently cleansing and drying the skin. Follow the prescribed directions rather than adding extra applications. Redness, dryness, scaling, itching, stinging, or burning can occur, especially early in treatment.
The label advises using moisturizer and, when needed, reducing application frequency or stopping treatment. The gel may increase sun sensitivity. Use sunscreen and protective clothing, and avoid applying it to already sunburned skin.
- Keep the gel away from the eyes and mouth.
- Do not apply it to broken or sunburned skin.
- Wash your hands after applying it.
- Protect colored towels, pillowcases, and clothing because benzoyl peroxide can bleach fabric.
- Be aware that benzoyl peroxide may also bleach hair.
Who should not use it?
Cabtreo is contraindicated for anyone with a relevant allergy to its ingredients or to lincomycin. It is also contraindicated for people with a history of regional enteritis, ulcerative colitis, or antibiotic-associated colitis.
These bowel-related restrictions matter because the product contains clindamycin. If diarrhea develops during treatment, stop using the gel and contact a clinician.
