Clindamycin and benzoyl peroxide topical gels combine an antibacterial ingredient with benzoyl peroxide in a fixed acne product. U.S. labels describe several strengths and brand families, including Acanya and Onexton. These prescription combinations differ from stand-alone clindamycin 1% gel and from OTC benzoyl peroxide.
When comparing a pharmacy listing, read both active ingredients and both stated strengths. A label may express the clindamycin salt as clindamycin phosphate and describe an amount equivalent to clindamycin base. Products containing benzoyl peroxide 2.5%, 3.75% or 5% cannot be reduced to a generic “clindamycin peroxide” listing without checking the complete label.
This page explains the two-ingredient product family, not how to purchase any particular brand. Use the prescription purchase guide for legitimate U.S. pharmacy steps, or the combination-product hub to compare retinoid-containing alternatives.
The combination delivers clindamycin phosphate and benzoyl peroxide together in a topical gel. The active ingredients address different parts of acne management. Product labels specify exact ingredient percentages, storage rules, age indications and administration instructions for that formulation.
Clindamycin is an antibiotic, so the product belongs to prescription acne care rather than a cosmetic cleanser category. Benzoyl peroxide may be available separately without a prescription, but that does not make a fixed antibiotic-containing gel over-the-counter.
| Example product family | Clindamycin phosphate label | Benzoyl peroxide | Product point |
|---|---|---|---|
| Acanya | 1.2% | 2.5% | Two-active prescription gel |
| Onexton | 1.2% | 3.75% | Different BPO concentration |
| Other fixed combinations | Check individual label | Some labels show 5% | Do not assume identical package or substitution |
| Plain clindamycin topical gel | Clindamycin only | Absent | Not the same as fixed combination |
| OTC benzoyl peroxide | Absent | Varies by OTC product | Does not contain prescription clindamycin |
Acanya labeling describes clindamycin phosphate 1.2% with benzoyl peroxide 2.5%, while Onexton identifies clindamycin phosphate 1.2% with benzoyl peroxide 3.75%. They therefore contain the same named pair of active ingredients but are not identical in concentration or brand-specific directions.
This distinction is more useful than a claim that one brand is “stronger” or clinically superior. For individual branding, see Acanya and Onexton; current marketing and pharmacy supply should be confirmed independently.
U.S. labels for clindamycin/benzoyl peroxide gels include presentations described as 1%/5% and as 1.2%/5%, alongside the 1.2%/2.5% and 1.2%/3.75% families. Read the complete label carefully: 1.2% clindamycin phosphate represents approximately 1% clindamycin base, so the printed percentages may partly reflect whether the salt or clindamycin-equivalent amount is stated.
That labeling distinction does not establish that two brands are automatically therapeutically equivalent. The pharmacist must verify the specific FDA-approved product and substitution status as well as benzoyl peroxide concentration, formulation and prescription wording. Do not infer an interchangeable gel from ingredient names or two percentage figures alone.
Dermatology guidance emphasizes combining topical antibiotics with benzoyl peroxide to help reduce the development of antibiotic resistance. In the fixed product, both ingredients are present in the prescribed formulation rather than supplied as independently selected containers.
This does not mean every acne regimen should contain a clindamycin antibiotic or that the patient should decide the proportion. The clinical decision belongs to the prescribing professional; the antibiotic resistance guide provides additional context.
Plain clindamycin gel contains the topical antibiotic but not the second benzoyl peroxide active. A pharmacy search may group both under the word “clindamycin,” which is insufficient for safe dispensing. The added ingredient changes the formula and counseling, including dryness and bleaching precautions.
The topical form overview covers gel, lotion and solution as single-ingredient vehicles. This page stays focused on fixed two-active formulations.
Benzoyl peroxide can dry or irritate the skin and can bleach fabrics or hair. Clindamycin/benzoyl peroxide labels also discuss erythema, scaling and local irritation. Adding abrasive cleansers, exfoliants or other irritating acne products may increase discomfort.
Patients should follow the actual prescription instructions and ask before combining the gel with other active skin treatments. More frequent use or extra product is not a reliable way to improve treatment and may worsen irritation.
U.S. labels for multiple clindamycin phosphate/benzoyl peroxide combination gels specify formal contraindications in patients with hypersensitivity to clindamycin, lincomycin, benzoyl peroxide or relevant ingredients, and in patients with a history of regional enteritis, ulcerative colitis or antibiotic-associated colitis. Those restrictions should not be softened into a general suggestion to mention stomach problems.
Topical clindamycin can be absorbed systemically. Diarrhea, bloody diarrhea and colitis have been reported; significant diarrhea during treatment requires prompt medical advice and following the product’s discontinuation directions. For the broader route-specific picture, see clindamycin side effects.
Look for both named active ingredients, their labeled percentages, topical gel route and the correct package form. Check the concentration pair against the electronic or written prescription. Some store catalogs abbreviate product descriptions, so confirmation with the dispensing pharmacist may be necessary.
A brand name, package photograph, barcode or price cannot establish that the exact formulation will be delivered. A licensed pharmacy must validate the actual dispensed item.
A clinician may consider whether a fixed-dose gel or separate topical products fits the patient’s regimen and tolerability, but those are not automatically equivalent plans. Timing, vehicles, convenience and irritation potential may differ. A fixed gel is not something to recreate by mixing products at home.
Benzoyl peroxide purchased by itself is a separate category discussed in the standalone benzoyl peroxide guide; it does not include prescription clindamycin.
Final pharmacy cost depends on the exact combination, package size, brand or generic status, formulary rules, pharmacy network and insurance benefit stage. Advertised savings may apply only to a narrowly defined product or eligibility group and should not be assumed.
Ask the dispensing pharmacy for a current patient-specific quote rather than relying on a generic national price. The topical clindamycin cost guide gives useful evergreen comparison factors.
These antibiotic-containing fixed gels require a legitimate U.S. prescription. Online listings that claim to dispense them without an authorized prescriber evaluation are not a reliable or lawful route. Licensed online and local pharmacies should be able to verify patient identity and provide pharmacist support.
Consult the online pharmacy credential checklist before using a remote seller. Do not interpret a telehealth advertisement as a guarantee of a specific acne prescription.
Ask whether the prescription specifies a particular strength pair, whether the pharmacist has verified an allowed equivalent, what instructions and warnings belong to that specific product, and whether insurance changes the covered brand. Keep the ingredient list available when discussing a proposed alternative.
The goal is a correctly identified, clinically authorized product rather than a generic “best” clindamycin gel. No brand ranking, stock guarantee or discount prediction is made here.
No. A fixed combination that contains clindamycin is a prescription medicine in the United States.
Both contain clindamycin phosphate and benzoyl peroxide, but the labeled benzoyl peroxide strength differs: 2.5% for Acanya and 3.75% for Onexton.
No. The fixed combination includes benzoyl peroxide as an additional active ingredient.
Yes. Benzoyl peroxide products can bleach hair or fabrics; follow the specific product instructions.
Dermatology guidelines recommend the combination to help limit antibiotic resistance.
Do not increase use on your own. Extra product can worsen irritation and may not improve outcomes.
No. The combination family includes different labeled strengths and formulations.
Any substitution must follow applicable rules and the actual prescription; consult the prescriber if the proposed product differs.
Yes. Topical clindamycin can be absorbed and has been associated with serious diarrhea or colitis. Multiple combination gel labels also formally contraindicate use after regional enteritis, ulcerative colitis or antibiotic-associated colitis.
