Clindamycin benzoyl peroxide gel: use, timeline and risks

Quick answer: Clindamycin and benzoyl peroxide gel is a prescription acne medicine that combines an antibiotic with an ingredient that also reduces acne-causing bacteria. The American Academy of Dermatology (AAD) says a topical antibiotic is used along with benzoyl peroxide to lower the risk of antibiotic resistance. The AAD also says it takes at least 6 to 8 weeks before you see fewer breakouts. The label we read says use past 12 weeks has not been evaluated.

This page covers what the gel is, why the two ingredients are paired, and how the label says to apply it. It also covers what to expect and who should not use it. The facts come from the FDA-approved label, the AAD, and a published acne guideline. Your own dermatologist decides whether it fits your skin.

What is clindamycin benzoyl peroxide gel?

It is a prescription gel for the skin. The label we read describes it as a combination of clindamycin phosphate (a lincosamide antibacterial) and benzoyl peroxide. It is indicated for the topical treatment of acne vulgaris in patients 12 years of age and older. Clindamycin is the antibiotic in the pair. Benzoyl peroxide is the second active ingredient.

The AAD explains that benzoyl peroxide reduces acne-causing bacteria on your skin. It adds that benzoyl peroxide is most effective when used along with another acne treatment that works on the other causes of acne. Some products combine both medicines in one pump or tube, so you apply one product instead of two.

Strengths vary from one product to the next. The AAD gives two examples: one medication may contain 5% benzoyl peroxide and 1% clindamycin, while another contains 2.5% benzoyl peroxide and 1.2% clindamycin. The label we read is for a 1.2% clindamycin and 3.75% benzoyl peroxide pump gel. Each product has its own label, so the directions below may not match the tube you were prescribed. Always follow your prescriber’s instructions and the label in your box.

Why does an antibiotic come paired with benzoyl peroxide?

The pairing exists because of antibiotic resistance. The AAD says that when an antibiotic is taken alone, it can quickly lose its ability to fight acne. When that happens, the bacteria keep growing and you can develop antibiotic resistance, which the AAD calls a global health problem.

For a topical antibiotic, the AAD says that you’ll use it along with an acne medication or wash that contains benzoyl peroxide. Doing so reduces your risk of developing resistance. The AAD also says some acne treatments combine the two in one product, which helps you get the right dose of each medication.

A published acne guideline also addresses combination treatment. The 2024 acne guidelines in the Journal of the American Academy of Dermatology (PubMed 38300170) make strong recommendations for benzoyl peroxide, topical retinoids, topical antibiotics, and oral doxycycline. They also list combining topical therapies with multiple mechanisms of action, and combining systemic antibiotics with topical therapies, as good practice statements.

So the pairing is meant to lower the risk of resistance. The AAD describes the combined products as a way to get the right dose of each medication.

How does the label say to apply the gel?

The directions below come from the 1.2% and 3.75% pump gel label. Other strengths can differ, so treat this as an example of how a label reads and not as your personal instructions.

Before applying, the label says to wash the face gently with a mild soap, rinse with warm water, and pat the skin dry. It then says to apply a pea-sized amount to the face once daily. The patient leaflet says one pea-sized amount should be enough for your entire face. You dot it over six areas (chin, both cheeks, nose, and both sides of the forehead) and then spread it gently. It says to wash your hands afterward.

The label says to avoid the eyes, mouth, mucous membranes, and areas of broken skin. It also says the gel is not for oral, eye, or vaginal use. If your doctor tells you to use it on other areas of skin with acne, the leaflet says to ask how much to use.

When should you throw the pump away?

The same label says to throw the gel away 8 weeks after the date of dispensing. It says to store the pump upright at room temperature and not to freeze it. The label also says use beyond 12 weeks has not been evaluated. If you are nearing 12 weeks, message your dermatologist or book a follow-up visit.

Put a check-in with your prescriber on your calendar when you start the gel, so a 12-week mark does not pass unnoticed.

How long does clindamycin benzoyl peroxide take to work?

It takes weeks and not days. The AAD says it takes at least 6 to 8 weeks before you start to see fewer breakouts. It adds that you need to stick to your treatment plan to see clearing.

The label’s trial data also shows when irritation tends to peak for that one product. In a 12-week trial of the 1.2% and 3.75% gel, most local skin reactions either stayed at baseline or rose and peaked around Week 4. They were near or better than baseline levels by Week 12. In plain terms, the skin can feel worse before it settles.

The same label reports results at Week 12. Among 253 people on the gel, 29% were rated clear or almost clear, compared with 15% of 245 people on the vehicle gel. The label also reports a mean reduction in inflammatory lesions of 60.4% for the gel and 31.3% for the vehicle. Those numbers describe a group in one trial. They do not predict your own skin.

Can you stay on it long term?

The patient leaflet says it is not known whether the gel is safe and effective for use longer than 12 weeks. For antibiotics in general, the AAD says dermatologists prescribe them for the shortest time possible, then use other medicines to keep skin clear. The AAD says most people can keep their skin clear by using medicine they apply to their skin in a maintenance plan. It adds that continuing that plan reduces the need for stronger acne medicine.

Your dermatologist decides what comes next, such as a retinoid. Our articles on how to use tretinoin cream and on adapalene versus tretinoin cover the topical retinoids.

What side effects should you expect?

The AAD lists dryness, irritated skin, peeling, burning, and worsening acne as possible side effects of these combination medications. It adds that you can reduce side effects by using the medication exactly as prescribed.

The label reports that burning sensation, contact dermatitis, itching, and rash each occurred in 0.4% of people treated in its trial. It describes these as reactions in less than 0.5% of subjects. Its skin reaction table shows redness, scaling, itching, burning, and stinging, most of them mild. The label also says the gel may cause irritation, especially when combined with other topical acne therapies. If irritation occurs, it says to reduce how often you apply it or pause treatment and resume once the irritation subsides. It adds that treatment should be discontinued if the irritation persists.

Can the gel bleach hair and colored fabric?

It can, according to the label, which says the gel may bleach hair or colored fabric. The patient leaflet tells you to avoid getting it in your hair or on colored fabric. Wash your hands after applying, and keep the gel away from your hair.

What should you know about sun exposure?

The label says to minimize sun exposure, including tanning beds and sun lamps, after applying the gel. The leaflet suggests a wide-brimmed hat or other protective clothing and sunscreen over the treated areas. The AAD advises sunscreen that offers broad-spectrum protection, SPF 30 or higher, and water resistance.

When should you stop the gel and call your doctor?

Clindamycin can reach the bloodstream even when it is applied to the skin. The label says that systemic absorption of clindamycin has been demonstrated following topical use. Diarrhea, bloody diarrhea, and colitis have been reported with topical and systemic clindamycin. According to the leaflet, colitis can show up during treatment and for several weeks after it ends.

• Severe stomach cramps, watery diarrhea, or bloody diarrhea: the leaflet says to stop the gel and call your doctor right away.
• Severe itching, swelling of the face, eyes, lips, tongue, or throat, or trouble breathing: the leaflet says to stop the gel and get help right away.
• A skin rash, or skin that becomes very red, itchy, or swollen: the leaflet says to stop the gel and call your doctor.

If your symptoms feel urgent, treat them as urgent and seek emergency care rather than waiting for a message reply.

Who should not use this combination gel?

The label lists two contraindications for this gel. The first is a known allergy to clindamycin, benzoyl peroxide, lincomycin, or any ingredient in the gel. The second is a history of regional enteritis, ulcerative colitis, or antibiotic-associated colitis. The leaflet also names Crohn’s disease in its list of reasons not to use the gel.

Tell your prescriber about the rest of your medicine list too. The label says to avoid using the gel with topical or oral erythromycin products. It also says clindamycin has neuromuscular blocking properties, so the gel should be used with caution in people receiving neuromuscular blocking agents. The leaflet also tells you to mention planned surgery, because the gel may affect how certain medicines given during surgery work.

On pregnancy, the label says there are no available data on this gel in pregnant women. The leaflet adds that it is not known whether the gel passes into breast milk. If either applies to you, raise it before your first dose. The label does not cover children under 12, because safety and effectiveness have not been evaluated in that age group.

How is it different from oral doxycycline?

The gel is applied to your skin. Doxycycline, by contrast, is a pill taken by mouth. The AAD says an oral antibiotic can effectively treat moderate-to-severe pimples but not nodular acne. The published guideline gives strong recommendations to both topical antibiotics and oral doxycycline.

The choice between them is a prescriber’s decision. Our article on doxycycline for acne covers the oral antibiotic, and doxycycline versus minocycline compares two pills. For a wider view of the options, see our acne treatment comparison.

What does a prescription visit look like online?

The leaflet calls this gel a prescription medicine, so a prescriber has to decide whether it fits you. At The Goal Is Clear (TGIC), the process starts with a short quiz, then you upload two photos and check out through secure billing. According to TGIC’s how it works page, a board-certified dermatologist licensed in your state reviews your case within 24 hours. You see their name, photo, and state license number before treatment starts.

That dermatologist can write a prescription, ask follow-up questions in your dashboard, or route you to in-person care if your case is out of scope. TGIC’s page for men lists topical antibiotics among the prescription topicals a dermatologist may start with, alongside retinoids and combination regimens. That is a list of options a dermatologist may consider. It is not a promise that you will get this gel, because a prescription is never guaranteed.

If a prescription is written, the partner pharmacy runs your insurance and ships the medication. Medication is billed separately by the pharmacy, as low as $0 for the prescription with insurance, and care costs are on the pricing page. In our work with pharmacies, the day a prescription moves between pharmacies is where days get lost. Neither pharmacy owns the clock during the handoff. We also find that big chains often skip savings programs unless the patient asks. Tell your prescriber early if you plan to change pharmacies.

Not every acne case is a topical case. If the gel and other topicals are not enough, or acne is severe or scarring, a dermatologist may talk with you about other options, including isotretinoin. The published guideline strongly recommends it for acne that is severe, causing psychosocial burden or scarring, or failing standard therapy. Read who qualifies for Accutane and our Accutane FAQ to see how that path works. A visit with your own local dermatologist is also a good choice if you prefer to be seen in person.

Common questions about clindamycin benzoyl peroxide gel

Do you need benzoyl peroxide with clindamycin? The AAD says that when a topical antibiotic is part of your treatment plan, you’ll use it along with an acne medication or wash that contains benzoyl peroxide. Doing so reduces your risk of developing antibiotic resistance. Some products put both in one tube.

How long does it take clindamycin and benzoyl peroxide to work? The AAD says it takes at least 6 to 8 weeks before you start to see fewer breakouts. The label we read reports that most local skin reactions either stayed at baseline or rose and peaked around Week 4 in its trial. It also says use beyond 12 weeks has not been evaluated.

Does clindamycin benzoyl peroxide bleach fabric and hair? It can, according to the label, which says the gel may bleach hair or colored fabric, so keep it away from your hair and from colored fabric.

Can you use this gel with erythromycin products? The label says to avoid combining them. The label says to avoid using the gel with topical or oral erythromycin-containing products, because of its clindamycin component. The label notes that laboratory studies have shown antagonism between the two, and that the clinical significance is not known.

Can you buy clindamycin and benzoyl peroxide gel without a prescription? The label we read describes it as a prescription medicine. Plain benzoyl peroxide is a separate product, and it is outside the scope of this page.

What should you take from this?

This gel is a two-ingredient prescription that pairs an antibiotic with benzoyl peroxide. The AAD says a topical antibiotic is used with benzoyl peroxide to reduce the risk of resistance, and that it takes at least 6 to 8 weeks to see fewer breakouts. Some dryness and irritation are possible. The label says the gel may bleach hair or colored fabric and advises limiting sun. The leaflet says to stop the gel and call your doctor right away for severe stomach cramps, watery diarrhea, or bloody diarrhea, during treatment and within several weeks after it. For signs of an allergic reaction, the leaflet says to stop and get help right away.

If you want a board-certified dermatologist to review your skin and tell you whether a topical like this fits, you can start the quiz at TGIC. It takes about two minutes, and a prescription is never guaranteed.
