In the US you can treat a lot of acne without a prescription. Adapalene 0.1% gel (sold as Differin Gel) has been over the counter since the FDA approved the switch on 8 July 2016, and since 22 May 2026 the adapalene 0.1% and benzoyl peroxide 2.5% combination has also been sold over the counter as Differin Epiduo. Benzoyl peroxide and salicylic acid have long been available off the shelf. Stronger retinoids, topical antibiotics, dapsone gel, oral antibiotics, spironolactone and isotretinoin still need a prescriber.

This guide sets out what you can buy without a prescription, what still needs one and how US patients usually get it, and what each common acne medicine costs US pharmacies in the federal NADAC price survey for the week of 28 October 2026. It then covers the iPLEDGE rules for isotretinoin, what the FDA says about importing medicine and spotting an unsafe online pharmacy, and what SafeRxPills sells. We sell acne medicines made in India, so we have a commercial interest; every figure here comes from an FDA label, an FDA page or database, or the CMS price file listed under Sources, and our own prices come from our product listings.

The short answer

Start with what is on the shelf if your acne is mild: adapalene 0.1% gel, adapalene 0.1% with benzoyl peroxide 2.5%, benzoyl peroxide 2.5% to 10%, or salicylic acid 0.5% to 2%. If that has not worked after the time the label gives (up to 3 months of once daily use for adapalene), or your acne is inflamed, scarring or widespread, see a prescriber in person or by telehealth. When you get a prescription, ask for the generic. In the October 2026 NADAC data, 30 g of generic clindamycin 1% gel cost US pharmacies $4.25 and 30 g of generic adapalene 0.3% with benzoyl peroxide 2.5% cost $19.42, while the brand of that same combination, Epiduo Forte, cost $449.02 for 30 g. Isotretinoin is different: in the US it is only dispensed through the iPLEDGE program, and there is no legal shortcut around it. For every acne option by severity, see our acne treatment hub.

What you can buy without a prescription in the US

The FDA lets two kinds of acne products be sold over the counter (OTC). The first kind follows the FDA's OTC acne monograph (M006), which lists the active ingredients and strengths any maker can use without an individual approval. The second kind is a specific product the FDA has switched from prescription to OTC through its own application, which is how adapalene arrived.

Active ingredientOTC strength allowedHow it got there
Benzoyl peroxide2.5% to 10%OTC monograph M006
Salicylic acid0.5% to 2%OTC monograph M006
Sulfur3% to 10% (3% to 8% with resorcinol)OTC monograph M006
Adapalene0.1% gel (Differin Gel)Rx-to-OTC switch, NDA 020380, 8 July 2016
Adapalene with benzoyl peroxide0.1% / 2.5% gel (Differin Epiduo)Partial Rx-to-OTC switch, NDA 220736, 22 May 2026

The monograph covers only the ingredients and strengths listed. Adapalene 0.3% gel, adapalene 0.1% cream and Epiduo Forte (adapalene 0.3% with benzoyl peroxide 2.5%) are still listed as prescription products in Drugs@FDA.

Adapalene over the counter: what changed in 2016 and 2026

Adapalene was first approved for prescription use in 1996. On 8 July 2016 the FDA approved Galderma's supplemental application to sell Differin Gel 0.1% over the counter "for the treatment of acne in adults and children ages 12 years and older", in tubes of 2 g, 15 g and 45 g. Before that decision, an FDA advisory committee had voted unanimously, in April 2016, that the safety of adapalene gel 0.1% for OTC use had been adequately shown.

The second change came in 2026. Drugs@FDA records NDA 220736, Differin Epiduo gel (adapalene 0.1% and benzoyl peroxide 2.5%), approved on 22 May 2026 as a partial Rx-to-OTC switch, in 15 g, 30 g and 45 g sizes. The original prescription Epiduo application is now listed as discontinued. The stronger Epiduo Forte stays prescription only.

What did not change: adapalene 0.3% gel and the 0.1% cream still need a prescription, and so do tretinoin and tazarotene. For how adapalene and tretinoin compare in trials, see our adapalene vs tretinoin guide.

How the OTC labels say to use adapalene

The Drug Facts labels for Differin Gel and Differin Epiduo give the same core directions for adults and children 12 years and older: use once daily, clean the skin gently and pat it dry, and cover the whole affected area with a thin layer (for acne on the face, the entire face). The labels state that applying more than directed will not give faster or better results but may worsen irritation.

  • Expect a slow start. Both labels say acne may appear to worsen in the early weeks, and that it may take up to 3 months of once daily use to see results.
  • Do not use on damaged skin (cuts, abrasions, eczema, sunburn) or if you are allergic to adapalene or any ingredient. The Epiduo label adds: do not use if you have very sensitive skin or are sensitive to benzoyl peroxide.
  • Sun and waxing. Limit sun exposure including tanning beds, use sunscreen outdoors, and do not wax treated areas.
  • Bleaching. The Epiduo label warns it may bleach hair and dyed fabrics, which is a benzoyl peroxide effect.
  • Pregnancy. Both labels say to stop use and ask a doctor if you become pregnant or plan to. Both labels also say to ask a doctor before use if pregnant or breastfeeding.
  • Children under 12. Differin Gel says ask a doctor; Differin Epiduo says do not use.

What still needs a prescription

Everything below is listed as a prescription product in the US. These are the medicines a prescriber usually reaches for when OTC products are not enough. Which cream works best by the trial evidence is covered in our prescription skin care medicine guide; this page sticks to access and cost.

MedicineFormWhat the US label says it is for
Tretinoin (Retin-A and generics)Cream, gelTopical treatment of acne vulgaris
Adapalene 0.3%, adapalene 0.1% creamGel, creamAcne vulgaris
Tazarotene 0.1% (Tazorac and generics)Cream, gelAcne vulgaris (also plaque psoriasis)

IsotretinoinCapsulesSevere recalcitrant nodular acne, age 12 and older, via iPLEDGE
SpironolactoneTabletsNot labeled for acne (used off label)

One trap: generic azelaic acid 15% gel, the one that appears in the price survey, is labeled in the US for the papules and pustules of rosacea, not for acne. The acne-labeled product is the 20% cream. Our azelaic acid cream guide explains the difference. For clindamycin gel specifically, see topical antibiotics for acne.

How US patients get an acne prescription

There are two common routes, and both end with a prescription sent to a pharmacy of your choice.

  • In person. A primary care clinician can prescribe most topical and oral acne medicines. A dermatologist is the usual route for severe, scarring or treatment-resistant acne, and for isotretinoin, which can only be prescribed by a prescriber registered with iPLEDGE.
  • Telehealth. Many prescribers assess acne by video or by reviewing photos and a questionnaire, where their state's rules allow. The prescription is then sent electronically to a US pharmacy or a mail-order pharmacy. Fees and what is included differ by service, so ask what you will pay for the visit and for the medicine before you start.

Isotretinoin has an extra in-person step. The FDA's iPLEDGE page states that all pregnancy tests before starting treatment must be done in a medical setting, even though prescribers may now allow home tests during and after treatment. A telehealth service can manage much of an isotretinoin course, but not that first step.

What NADAC is, and why it is not your shelf price

NADAC stands for National Average Drug Acquisition Cost. CMS runs a monthly nationwide survey of the invoice prices that retail community pharmacies, both chains and independents, pay for covered outpatient drugs, and publishes the averages weekly. State Medicaid programs can use it to set what they reimburse.

That makes NADAC useful for one thing: comparing what one medicine costs against another at the wholesale level, on the same day, with no marketing markup or coupon in the way. It is not the price you pay. Your price at the counter adds the pharmacy's margin and dispensing fee, and depends on your insurance, deductible, any discount program and the pharmacy you use. Read the figures below as "what the pharmacy paid", and expect to pay more.

Two more points. NADAC lists drugs per gram, per milliliter or per tablet, so the charts below multiply by a fixed amount (30 g or 30 units) to make the numbers readable. And NADAC covers some OTC products: in this week's file every adapalene 0.1% gel and benzoyl peroxide gel row is flagged as OTC, while the adapalene 0.1% with benzoyl peroxide 2.5% rows are prescription generics.

What topical acne medicines cost US pharmacies

These are the median NADAC figures for the latest week available, 28 October 2026, for generic versions of each product. The "per 30 g" column is simple multiplication; actual tubes and pumps come in different sizes.

Figure 1. What US pharmacies paid for 30 g of each generic topical acne medicine in the week of 28 October 2026. These are acquisition costs, not the price at the counter. Source: CMS NADAC.

Three things stand out. Generic clindamycin gel is the cheapest prescription topical in the list, about one thirteenth of the cost of tazarotene cream per gram. The tretinoin creams do not rise in price with strength: in this week's data the 0.05% cream cost more per gram than the 0.1% cream. And form matters as much as molecule: generic tazarotene 0.1% gel cost $6.03116 per gram ($180.93 per 30 g), more than three times the cream, and the tretinoin gels ($2.60844 per gram for 0.025%) cost several times the creams. For tretinoin prices in more detail, see buy tretinoin online.

What oral acne medicines cost US pharmacies

Oral medicines are priced per capsule or tablet. The table shows the NADAC for one unit and for 30 units. Thirty units is not a dose: your prescriber sets the dose and how long you take it.

Generic productNADAC per unitPer 30 units
Spironolactone 50 mg tablet$0.08328$2.50
Doxycycline hyclate 100 mg capsule$0.10794$3.24
Doxycycline hyclate 100 mg tablet$0.11995$3.60
Minocycline 100 mg capsule$0.33466$10.04
Minocycline 100 mg tablet$0.64629$19.39
Isotretinoin 20 mg capsule (Claravis, Amnesteem, Zenatane)$1.93429$58.03
Isotretinoin 20 mg capsule (sold under the generic name)$4.18071$125.42
Bar chart of US pharmacy acquisition cost for 30 capsules or tablets, week of 28 October 2026: spironolactone 50 mg $2.50, doxycycline hyclate 100 mg capsules $3.24, minocycline 100 mg capsules $10.04, isotretinoin 20 mg sold as Claravis, Amnesteem or Zenatane $58.03, isotretinoin 20 mg sold under the generic name $125.42.
Figure 2. Pharmacy acquisition cost of 30 units of each oral medicine used for acne. Spironolactone is not FDA-approved for acne. Source: CMS NADAC, week of 28 October 2026.

Doxycycline and minocycline are cheap at the pharmacy level, but the US labels describe them only as "useful adjunctive therapy" in severe acne, and modified-release versions cost much more: doxycycline hyclate delayed-release 100 mg tablets were $2.16424 each in the same week. Our doxycycline for acne guide covers dose and duration, and doxycycline vs minocycline compares the two.

Brand vs generic: where the gap is biggest

Brand acne products can cost many times their generic equivalents. NADAC had current brand entries for only a few acne products this year; Aczone, Retin-A, Tazorac and Solodyn had no 2026 NADAC rows, so they are left out rather than estimated.

ProductBrand NADAC per gramGeneric NADAC per gramBrand per 30 gGeneric per 30 g
Adapalene 0.3% / benzoyl peroxide 2.5% (Epiduo Forte gel pump; the generics priced are also 45 g pumps)$14.96720$0.64744$449.02$19.42
Adapalene 0.1% cream (Differin)$11.27062 (last reported 13 May 2026)$2.72225$338.12$81.67
Grouped bar chart of US pharmacy acquisition cost for 30 g. Adapalene 0.3% with benzoyl peroxide 2.5%, all 45 g pump bottles: brand Epiduo Forte $449.02, generic $19.42. Adapalene 0.1% cream: brand Differin $338.12, generic $81.67.
Figure 3. The same medicine at the same strength, brand against generic, in pharmacy acquisition cost. The Differin cream figure is its last NADAC entry, from May 2026. Source: CMS NADAC.

Epiduo Forte cost pharmacies about 23 times the generic per gram, and Differin cream about 4 times. If a prescription is written for a brand name, ask the prescriber or pharmacist whether a generic of the same strength and form is available. Note the form: the generic adapalene 0.1% cream is itself far more expensive per gram than the OTC 0.1% gel.

Isotretinoin: the cost of a full course

The US isotretinoin labels recommend 0.5 to 1 mg/kg/day in two divided doses for 15 to 20 weeks. For a 60 kg patient at 1 mg/kg/day, that is 30 mg twice daily, or 280 capsules of 30 mg over 20 weeks. The table prices that example using the 28 October 2026 NADAC for a 30 mg capsule.

Product (30 mg capsule)NADAC per capsule280 capsules (20 weeks)210 capsules (15 weeks)
Claravis, Amnesteem, Zenatane$2.01016$562.84$422.13

Bar chart of the pharmacy acquisition cost of a 20-week isotretinoin course for a 60 kg patient at 1 mg/kg/day (280 capsules of 30 mg): Claravis, Amnesteem or Zenatane $562.84, isotretinoin sold under the generic name $1,519.77, Absorica $10,706.02.

Claravis, Amnesteem and Zenatane are generic isotretinoin capsules sold under trade names, and NADAC classes them as generics. Absorica is a different formulation that can be taken with or without meals; its label says it is not substitutable with Absorica LD on a milligram basis. Lab tests and the iPLEDGE visits are extra. Our isotretinoin for acne guide covers results, relapse and side effects.

iPLEDGE: what the program requires

Every isotretinoin label carries a boxed warning: isotretinoin "can cause life-threatening birth defects and is contraindicated in pregnancy." Because of that risk, the FDA requires all isotretinoin to be supplied through a single restricted program, iPLEDGE, which began in 2005 and became a REMS in 2010. According to the label and the FDA:

  • Prescribers must be certified, assess each patient's reproductive status, counsel patients, review pregnancy tests and report all pregnancies.
  • Pharmacies must be certified, and can only dispense once the system confirms the requirements have been met.
  • Patients who can become pregnant must enroll, follow the pregnancy testing and prevention rules, show they understand the risks before each prescription, and collect each prescription within 7 days of the pregnancy test.
  • Patients who cannot become pregnant must enroll, must not share isotretinoin and must not donate blood.

On 9 February 2026 the FDA approved changes to reduce the burden: prescribers may now allow at-home pregnancy tests during and after treatment, the waiting period for repeat tests after a missed 7-day window was removed, and patients who cannot get pregnant no longer need monthly documentation of counseling. Pre-treatment pregnancy tests must still be done in a medical setting. The iPLEDGE contact center is 866-495-0654.

Why isotretinoin cannot legally be bought around iPLEDGE in the US

The FDA states that health care professionals and pharmacies "must be registered with iPLEDGE to be able to prescribe and dispense isotretinoin to patients", and that patients must also be enrolled to receive it. A pack posted from another country is not dispensed by an iPLEDGE-certified pharmacy, so it sits outside the only lawful US route. The FDA's personal importation page (next section) lists a product that "appears to present a serious risk to health" among the reasons it would refuse a personal import, and the label calls the risk of birth defects "extremely high" if pregnancy occurs during treatment.

There are medical reasons too. The label lists psychiatric effects, including depression and, rarely, suicidal thoughts, and reports intracranial hypertension (raised pressure in the skull) with isotretinoin, some cases involving tetracyclines, so it says to avoid using tetracyclines such as doxycycline and minocycline at the same time. It also requires a fasting lipid profile and liver tests before starting. Those checks are part of what you lose by skipping the program.

Spironolactone for hormonal acne: what the label does and does not say

Some prescribers use spironolactone off label for acne in women. Its US label (Aldactone, Pfizer) lists heart failure, hypertension, edema from cirrhosis or nephrotic syndrome, and primary hyperaldosteronism; acne is not among the approved uses. Whoever prescribes it, the safety information comes from that label:

  • It is contraindicated with hyperkalemia, Addison's disease and use of eplerenone.
  • It can cause hyperkalemia; the label says to check potassium within 1 week of starting or changing the dose and regularly after.
  • It can cause gynecomastia, and the label notes animal findings that it may affect sex differentiation of a male fetus.

Generic spironolactone is cheap at the pharmacy level ($0.08328 per 50 mg tablet in October 2026), but it needs a prescriber who will monitor potassium.

Safety rules that apply whatever the price

A cheaper source does not change the label. The points patients most often miss:

  • Tazarotene cream and gel are contraindicated in pregnancy; the label says retinoids may cause fetal harm.
  • Clindamycin topical products are contraindicated in people with a history of regional enteritis, ulcerative colitis or antibiotic-associated colitis.
  • Dapsone gel: methemoglobinemia leading to hospital admission has been reported; people with G6PD deficiency or congenital or idiopathic methemoglobinemia are more susceptible.
  • Doxycycline and minocycline: tetracyclines used during tooth development (last half of pregnancy, infancy and childhood to age 8) may cause permanent tooth discoloration.
  • Epiduo Forte is contraindicated in people with a history of hypersensitivity to benzoyl peroxide or any ingredient.

Practical ways to pay less

  • Try the OTC options first for mild acne, and give adapalene the full time its label allows before deciding it has failed.
  • Ask for the generic and the cheaper form. A cream is often cheaper per gram than a gel or pump of the same drug.
  • Check the strength. A higher strength is not always more expensive, as the tretinoin figures show, and the reverse can also be true.
  • Compare pharmacies and ask the cash price as well as the insured price.
  • For isotretinoin, ask whether a lower-cost generic brand such as Claravis, Amnesteem or Zenatane can be dispensed; in October 2026 they cost pharmacies less than half of isotretinoin sold under the generic name.

Buying acne medicine from abroad: what the FDA says

The FDA's personal importation page is direct: "In most circumstances, it is illegal for individuals to import drugs or devices into the U.S. for personal use because these products purchased from other countries often have not been approved by the FDA for use and sale in the U.S." It says the FDA "recommends only obtaining medicines from legal sources in the U.S."

The same page says FDA staff "may consider a more permissive decision" in some situations, for example where the product is not for a serious condition and there is no known significant health risk, or, for a serious condition, where effective treatment is not available in the US, there is no promotion to US residents, the product does not represent an unreasonable risk, the consumer affirms in writing that it is for personal use, the quantity is generally not more than a three month supply, and the consumer gives the name of a US-licensed doctor or evidence that treatment began abroad. These are discretionary, not a right. Read the FDA personal importation page yourself and check your own situation before you order anything from outside the US.

Warning signs of an unsafe online pharmacy

The FDA's BeSafeRx campaign gives a simple test. A safe online pharmacy is licensed by a US state board of pharmacy (you can check with the FDA's state license locator), requires a prescription from a licensed health care provider, gives a physical address and a US telephone number, and has a licensed pharmacist available to answer questions. The FDA says if a pharmacy is not in the state database, do not use it.

The FDA's red flags include:

  • selling prescription medicines without requiring a prescription;
  • deep discounts or prices that seem too good to be true;
  • unsolicited mail, email or spam offering cheap medicines;
  • being located outside the US or stating that medicines ship from a foreign country;
  • on arrival: broken or damaged packaging, misspellings, no expiry date or an expired product, or charges for a drug you never ordered.

Our longer checklist is in how to verify a legitimate online pharmacy.

What SafeRxPills sells for acne, and what it is not

Measured against the FDA test above, you should know what we are. SafeRxPills is run from Surat, Gujarat, India, and sells medicines made in India. Our own site states: "We are not licensed by the FDA." Our about page says SafeRxPills is operated by Actiza Pharmaceutical Pvt. Ltd., and our Acticycline listing names its maker as Actiza Pharma Pvt. Ltd., so our operator's name matches the listed maker of that product. We do not claim to be a US state-licensed pharmacy, our acne listings are not marked as requiring a prescription, and we are based outside the US. Those are points on the FDA's list, so read the import rules above and decide with that in mind.

Prices as of 28 October 2026, from our live product listings:

Acticycline 100 mg (Actiza)Doxycycline 100 mg100 capsules $30.00; 300 capsules $68.75$0.30 to $0.23
Cynomycin 100 mg (Pfizer India)Minocycline 100 mg28 capsules $120.00; 84 capsules $212.50$4.29 to $2.53

Be careful comparing these with NADAC. Our listings do not state the tube size for every product, and NADAC is a pharmacy's cost, not a patient's price. For the oral antibiotics the comparison is clear and not in our favor: US pharmacies paid $0.10794 for a doxycycline 100 mg capsule and $0.33466 for a minocycline 100 mg capsule, against our $0.30 to $0.23 and $4.29 to $2.53, so a US patient with a prescription may well pay less at a local pharmacy. We also list isotretinoin capsules. We do not link them here, and we do not suggest that anyone in the US use them as a way around iPLEDGE.

Questions to ask your prescriber or pharmacist

  • Is my acne mild enough to try OTC adapalene or benzoyl peroxide first, and for how long?
  • Is there a generic of what you are prescribing, and is the cream cheaper than the gel?
  • Should I combine a retinoid with benzoyl peroxide, and in one product or two?
  • If you prescribe doxycycline or minocycline, how long should I take it, and with what topical?
  • Am I a candidate for isotretinoin, and what will iPLEDGE involve for me?
  • If spironolactone is suggested, how often will my potassium be checked?
  • Is any of this unsafe if I become pregnant?

?Frequently Asked Questions

Is adapalene over the counter in the US?

Yes, at the 0.1% gel strength. The FDA approved Differin Gel 0.1% for over-the-counter use on 8 July 2016 for adults and children 12 years and older. Since 22 May 2026 the adapalene 0.1% and benzoyl peroxide 2.5% gel has also been sold over the counter as Differin Epiduo. Adapalene 0.3% gel, adapalene 0.1% cream and Epiduo Forte still need a prescription.

How long does over-the-counter adapalene take to work?

The Differin Gel and Differin Epiduo labels both say it may take up to 3 months of once daily use to see results, and that acne may look worse in the early weeks. Use a thin layer once a day; the labels say applying more will not work faster and may worsen irritation.

Is Epiduo available without a prescription now?

The original strength is. Drugs@FDA lists Differin Epiduo (adapalene 0.1% and benzoyl peroxide 2.5%) as an over-the-counter product approved on 22 May 2026, and its Drug Facts label covers adults and children 12 years and older. Epiduo Forte, the 0.3% and 2.5% version, remains prescription only.

What acne treatments can I buy without a prescription in the US?

Adapalene 0.1% gel, adapalene 0.1% with benzoyl peroxide 2.5% gel, and products made under the FDA's OTC acne monograph: benzoyl peroxide 2.5% to 10%, salicylic acid 0.5% to 2%, and sulfur 3% to 10% (3% to 8% when combined with resorcinol).

What is the cheapest prescription acne medicine?

By US pharmacy acquisition cost in the week of 28 October 2026, generic clindamycin 1% gel was the cheapest prescription topical at $0.14183 per gram ($4.25 for 30 g). Among oral options, generic doxycycline hyclate 100 mg capsules were $0.10794 each. What you pay at the counter will be higher, and the right medicine depends on your acne, not the price.

What does NADAC mean?

NADAC is the National Average Drug Acquisition Cost. CMS surveys the invoice prices US retail community pharmacies pay for covered outpatient drugs each month and publishes the averages weekly. It shows what pharmacies paid, not what patients are charged, so treat it as a benchmark for comparing medicines, not as the price you will pay.

How much does a course of isotretinoin cost?

In a worked example of 30 mg twice daily for 20 weeks (280 capsules, the label dose of 1 mg/kg/day at 60 kg), US pharmacy acquisition cost on 28 October 2026 was $562.84 for Claravis, Amnesteem or Zenatane, $1,519.77 for isotretinoin sold under the generic name and $10,706.02 for Absorica. Visits and lab tests are extra.

Can I get isotretinoin in the US without iPLEDGE?

No. The FDA says prescribers and pharmacies must be registered with iPLEDGE to prescribe and dispense isotretinoin, and patients must be enrolled to receive it. The label has a boxed warning that isotretinoin can cause life-threatening birth defects and is contraindicated in pregnancy. Isotretinoin posted from abroad is outside the program, and we do not suggest using it that way.

Is spironolactone FDA-approved for acne?

No. The US Aldactone label lists heart failure, hypertension, edema and primary hyperaldosteronism. Prescribers may use it off label for acne in women. The label says it is contraindicated with hyperkalemia, Addison's disease or eplerenone use, and to check potassium within 1 week of starting or changing the dose.

Is it legal to import acne medicine from another country into the US?

The FDA's personal importation page says that in most circumstances it is illegal for individuals to import drugs for personal use, and recommends getting medicines only from legal sources in the US. It describes limited situations where FDA staff may use discretion, such as a supply of generally not more than three months. Read the FDA page and check your own situation before ordering.

How can I tell if an online pharmacy is safe?

The FDA's BeSafeRx campaign says a safe online pharmacy is licensed by a US state board of pharmacy, requires a prescription from a licensed provider, lists a physical address and US phone number, and has a licensed pharmacist available. Red flags include no prescription needed, prices that seem too good to be true, spam offers, and shipping from another country.
