Key takeaways
- Isotretinoin is not a last resort. The 2024 AAD guideline recommends it for severe acne and for acne that is scarring, distressing, or not responding to standard treatment [2].
- In a 2026 study of 71,340 U.S. patients, more than a quarter started isotretinoin as their first acne treatment, and half had finished a course by about six months [1].
- Acne can return. Within a year of stopping, about 1 in 20 restarted isotretinoin and about 1 in 8 started an oral antibiotic. Most needed neither [1].
Isotretinoin, still called Accutane by almost everyone even though that brand left the market years ago, gets more strong opinions on social media than any other acne treatment. Some of what circulates is right. Some is out of date. A large 2026 study gives us real numbers to check three of the most common claims against.
The study, in plain terms
Researchers led by Dr. John Barbieri looked at insurance claims for 71,340 people in the United States, ages 10 to 49, who were treated with isotretinoin for acne between 2017 and 2023 [1]. Claims data records which prescriptions were filled and when, so it shows how the drug is actually used across thousands of dermatology and primary care offices, not how a textbook says it should be used. It cannot tell us how severe anyone’s acne was, what dose they took, or how they felt about it, and that limitation matters for the first claim below. The study was funded by Sanofi, a drug company, and published in an open-access journal, so anyone can read it in full [1].
Claim 1: “Accutane is a last resort. You only get it after everything else fails.”
Partly a myth. In the study, 28.4 percent of patients started isotretinoin without any prior acne prescription on record, and half of all patients had been on an oral antibiotic first [1]. Adults and males were the most likely to start without a prior treatment; only about 1 in 7 females did [1].
Is that a problem? Not necessarily. The American Academy of Dermatology’s 2024 guideline strongly recommends isotretinoin for acne that is severe, that is causing psychosocial burden or scarring, or that has failed standard oral or topical therapy [2]. Scarring and distress are on that list on their own. A patient with deep, scarring acne on their first visit may be exactly the right person to start isotretinoin without months of creams first.
The label still says “severe recalcitrant nodular acne,” and the study authors point out that use in practice is broader than that wording [1]. They also make the opposite argument to the “last resort” idea: because so many patients spend months on oral antibiotics first, they suggest considering isotretinoin earlier in severe acne to limit antibiotic exposure [1]. What we take from this: the decision is about the acne in front of us and the risk of permanent scarring, not about a checklist of products you have to fail first.
Claim 2: “One course and your acne is gone forever.”
A myth, though it is true for many people. The study followed patients for a year after they stopped. In that year, 5.4 percent restarted isotretinoin and 12.1 percent started an oral antibiotic for acne [1]. Read the other way, more than 80 percent did not need either within a year.
So the honest answer is: isotretinoin produces long remissions for most people, and a minority need more treatment, sometimes a second course. The study also found what raises the odds of needing more treatment: gaps in the course. Patients who missed 1 to 30 days had almost double the risk of restarting an acne medication, and those with a 31 to 60 day gap had more than three times the risk, compared with patients who took it without interruption [1]. Longer courses were associated with lower risk, and females had a somewhat higher risk than males [1]. That is the practical lesson: finish the course as prescribed, and do not let a refill lapse.
Claim 3: “You have to take it for a year.”
A myth. We generally try to keep an isotretinoin course to around six months total when possible. In the study, half of the patients had stopped by 5.97 months, about six months. Only 5.2 percent were still taking it at nine months, and 0.8 percent at a year [1].
That said, some patients do need to extend their course. Treatment length depends on factors such as body weight, the dose being used, side effects, and how the skin responds. If a patient needs eight or nine months of treatment, that does not necessarily mean anything went wrong. It may simply mean the dose needed to be adjusted or the course extended to achieve the desired result.
We also generally do not favor the trend of “microdosing” isotretinoin simply to stay on the medication longer. While lower-dose regimens may be appropriate for certain patients, our goal is to use an effective, individualized dose and complete the course when it is no longer needed, rather than keeping someone on isotretinoin indefinitely at a very low dose.
What we tell our patients
Isotretinoin is one of the most effective tools we have for treating acne, and for the right patient, it can change the course of the disease rather than just keeping breakouts under control month to month. I also tell my patients that it is a medication we take seriously. Dry lips and dry skin are expected, we monitor blood work when appropriate, pregnancy prevention is strict for anyone who can become pregnant, and we have an honest conversation about mood and mental health. My goal is not to keep you on isotretinoin forever or to use the lowest possible dose just for the sake of being on it longer. I generally aim for a course of about six months, but some patients need longer depending on their dose, response, and side effects. For someone who is starting to scar or has acne that is not responding to other treatments, I would rather have a thoughtful conversation about isotretinoin than wait until the acne has left permanent marks.
In Central Florida, we also have to plan around sun, heat, and sweat. Isotretinoin can make your skin more sensitive and less tolerant of irritation, so sunscreen, shade, and a simple skin-care routine become especially important. You can still exercise, play sports, swim, and live your life. We just want to be smart about sun exposure and avoid turning a medication that is helping your acne into a reason for your skin to become unnecessarily irritated.
When to see a dermatologist
If your acne is leaving marks or scars, if it is affecting how you feel about going out, or if you have used over-the-counter products for two or three months without a clear change, it is time for a visit. Those are the situations where the guideline says stronger treatment, sometimes including isotretinoin, should be on the table [2].
Questions patients ask
Is Accutane only for the most severe acne?
No. The American Academy of Dermatology's 2024 guideline strongly recommends isotretinoin for acne that is severe, is causing scarring or real distress, or has not responded to standard treatment. Scarring and distress count even when the acne does not look dramatic.
How long is a course of isotretinoin?
In a 2026 study of 71,340 patients in the United States, half had finished by about six months, and fewer than 1 in 100 were still taking it at a year. Your dermatologist sets the length based on your weight, your dose, and how your skin responds.
Can acne come back after Accutane?
Yes, for some people. In the same study, about 1 in 20 restarted isotretinoin and about 1 in 8 started an oral antibiotic within a year of stopping. Most did neither. A second course is an option if it happens.
Will I need blood tests?
Yes. Blood tests before and during treatment check your liver and blood fats, and pregnancy testing is required for anyone who can become pregnant. Your dermatologist will explain the schedule at your first visit.
