Accutane’s side effects hit nearly everyone who takes it, but most are manageable and temporary. In a study of 377 patients, 91.2% experienced at least one side effect during treatment, with dry, cracked lips affecting roughly 90% of users. That sounds alarming on paper, but the reality is that the vast majority of these effects are predictable, dose-dependent, and resolve after treatment ends. If your dermatologist has recommended isotretinoin for severe nodular acne that hasn’t responded to antibiotics or other therapies, understanding exactly what to expect month by month can make the difference between a smooth course and an unnecessarily stressful one. The original brand name “Accutane” was actually discontinued in the U.S.
market, though the name stuck in everyday conversation. Today, the same drug is sold as Claravis, Amnesteem, Myorisan, and Absorica, and it remains widely prescribed, with over one million prescriptions filled in 2021 alone. A 2025 cross-sectional study published in Scientific Reports found that 86.2% of patients expressed overall satisfaction with their treatment, and 74.5% reported significant acne improvement. Those numbers tell an important story: isotretinoin works, and works well, but it comes with a list of side effects that ranges from the nearly universal dry lips to rare but serious concerns involving pregnancy, mental health, and liver function. This article walks through all of it, including a detailed treatment timeline, the latest research, costs, and what the iPLEDGE program means for your day-to-day life on this medication.

What Are the Most Common Accutane Side Effects You Should Expect?
The side effect you will almost certainly experience is cheilitis, the clinical term for severely dry and cracked lips. It affects approximately 90% of patients, and for many people it’s the first sign the medication is doing its job. This isn’t the kind of dryness that a standard lip balm fixes once and forgets. Most dermatologists recommend applying a heavy occlusive like Aquaphor or CeraVe Healing Ointment multiple times a day, and some patients carry it everywhere for the duration of their course. Dry skin beyond the lips is also extremely common, with a five-year retrospective study from Poland finding that 70% of patients developed xerosis and 20% experienced retinoid dermatitis. You should expect to overhaul your skincare routine before you even start, switching to gentle, fragrance-free cleansers and rich moisturizers. Beyond dryness, the manufacturer data shows that back pain, elevated triglycerides, and joint pain each affect more than one in five patients.
These aren’t trivial complaints. Some patients describe the joint pain as feeling decades older than they are, particularly during exercise. Elevated triglycerides are usually caught early through the required monthly blood work, and if levels spike significantly, your dermatologist may lower your dose or pause treatment. Liver test abnormalities show up in up to 15% of patients, which is the primary reason blood draws aren’t optional on this drug. To put it concretely: if you’re a college student starting isotretinoin before a sports season, you need to plan around the possibility that joint pain and fatigue could affect your performance for four to five months. One side effect that catches people off guard is the initial acne flare, sometimes called the “purge.” During weeks one through four, your acne may actually get worse before it gets better. This flare can last one to two months and is psychologically difficult for people who started the drug because their acne was already severe. Knowing it’s coming doesn’t make it pleasant, but it does prevent the panicked assumption that the medication isn’t working.
The Accutane Treatment Timeline From Start to Clear Skin
The typical isotretinoin course runs 15 to 20 weeks, and the changes happen in a fairly predictable sequence. During weeks one and two, your skin becomes noticeably less oily. People who have battled oily skin for years often describe this as the first pleasant surprise of treatment. By weeks two through four, however, the purge phase can kick in, and the reduced oil production may be overshadowed by an increase in breakouts. This is the hardest stretch for most patients, and it’s worth having a direct conversation with your dermatologist about what to do if the flare is severe. Some prescribers add a short course of oral steroids to manage particularly bad flares, though this isn’t standard for everyone. Months two and three are when the tide turns.
Significant improvement typically begins in this window, and by month four, complete clearance is expected for most patients. However, if your acne is deeply cystic or if you’re on a lower dose, the timeline may stretch longer. Not everyone clears by month four, and that doesn’t mean the treatment has failed. Your dermatologist may extend the course or adjust the cumulative dose target based on your body weight and response. What surprises many patients is that isotretinoin continues working for two to four months after you stop taking it. The drug accumulates in the body and its effects on oil gland activity persist well beyond the last pill. This is also why pregnancy prevention must continue for at least one month after the final dose, and why some side effects like dryness taper gradually rather than vanishing overnight. If you finish your course and still have a few lingering spots, it’s often worth waiting before assuming you need a second round.
Serious Side Effects Including Birth Defects and Mental Health Concerns
Isotretinoin is a known teratogen, meaning it causes birth defects at extremely high rates. Even small doses taken for short periods can result in life-threatening birth defects, miscarriage, or fetal death. This is not a theoretical risk or a legal disclaimer buried in fine print. It is the reason the entire iPLEDGE REMS program exists, the reason monthly pregnancy tests are required for patients who can become pregnant, and the reason two forms of birth control must be used simultaneously during treatment. There is no safe dose of isotretinoin during pregnancy, and this is one area where the medical community speaks without any ambiguity. The psychiatric side effects are more complicated. The FDA issued a black box warning in 2005 for suicide, depression, aggression, and psychosis. UK MHRA data collected through March 2017 documented 5,577 adverse reactions, of which 1,207, or 22%, were psychiatric.
Those psychiatric reports included 85 cases of suicidal ideation, 56 reports of suicide, and 43 suicide attempts. A 2025 cross-sectional study from Syria found that 56.3% of isotretinoin users reported psychological symptoms including anxiety, mood changes, and depression. These numbers are concerning and deserve to be taken seriously by every patient and prescriber. However, the picture is not straightforward. Repeated high-quality meta-analyses have not confirmed a causal link between isotretinoin and depression or suicide. Severe acne itself is strongly associated with depression, anxiety, and reduced quality of life, which makes it difficult to untangle whether mood changes during treatment are caused by the drug, the underlying condition, or the stress of dealing with a months-long medical regimen. What this means practically is that you should monitor your mood, your prescriber should ask about it at every visit, and anyone with a history of depression should have a clear plan in place before starting treatment. The absence of a confirmed causal link does not mean the risk is zero, it means the relationship is complex and individual monitoring is essential.
How to Manage Accutane Side Effects During Your Treatment Course
Managing isotretinoin side effects starts before you fill the first prescription. Stocking up on the right products can prevent the worst of the dryness from catching you off guard. For lips, a thick petroleum-based ointment applied throughout the day and overnight is the standard recommendation. For skin, a fragrance-free moisturizer used twice daily, paired with a gentle cleanser, replaces whatever acne-fighting routine you were using before. Harsh exfoliants, retinol serums, and benzoyl peroxide washes typically need to be stopped entirely because isotretinoin already makes the skin far more sensitive and prone to irritation. The tradeoff with joint and muscle pain is activity modification versus pushing through it. Some patients continue exercising at their normal intensity and tolerate the discomfort. Others find that high-impact activities like running or heavy lifting become genuinely painful, and switching to swimming, cycling, or yoga during treatment is a better strategy.
There’s no consensus on the right approach because the severity varies enormously from person to person. What does matter is recognizing that this side effect is real and not a reason to doubt the drug’s effectiveness. If you’re an athlete or someone whose daily life involves physical labor, talk to your dermatologist about dose timing and whether a lower dose over a longer course might reduce musculoskeletal symptoms. For the metabolic side effects, specifically elevated triglycerides and liver enzyme changes, the management strategy is built into the treatment protocol. Monthly blood work catches these early. A 2025 systematic review on lipid profiles found that isotretinoin is associated with mild increases in total cholesterol, triglycerides, and LDL. The authors stated that regular monitoring is recommended but “not deemed paramount,” suggesting that for most patients, these elevations are modest and self-resolving. That said, if you have a pre-existing lipid disorder or a family history of cardiovascular disease, your dermatologist will likely watch these numbers more closely and may involve your primary care physician.
Rare but Documented Risks Including Sexual Dysfunction and Organ Effects
Beyond the common side effects, isotretinoin carries a list of rare but documented risks that patients should know about. Sexual dysfunction, including erectile dysfunction, reduced libido, and vaginal dryness, has been reported. The UK MHRA issued a specific Drug Safety Update in October 2017 regarding these risks, and what makes them particularly concerning is that some cases have persisted after stopping the medication. The frequency of persistent sexual side effects is not well established, and many dermatologists consider them rare, but the reports are real enough that a regulatory agency felt compelled to issue a formal warning. Pseudotumor cerebri, a condition involving increased pressure in the brain, is another rare but serious possibility. Symptoms include severe headaches, visual disturbances, and nausea.
If you’re taking isotretinoin and you develop a persistent, unusual headache, particularly one that worsens when lying down, contact your prescriber immediately. This risk increases if isotretinoin is taken alongside tetracycline antibiotics, which is one reason your dermatologist will review your full medication list before prescribing. Pancreatitis, severe skin reactions such as toxic epidermal necrolysis, and inflammatory bowel disease have also been reported in the medical literature, though recent studies have not established a causal link between isotretinoin and inflammatory bowel disease specifically. The 2025 comprehensive review published on PubMed cataloged side effects ranging from the common mucocutaneous issues all the way to rare cases of psychosis, rhabdomyolysis, and autoimmune diseases. This doesn’t mean you should expect any of these outcomes. It means that isotretinoin is a powerful drug with systemic effects, and the monitoring requirements exist for good reason. The 19.9% discontinuation rate found in the 2025 Syrian study, where nearly one in five patients stopped treatment due to side effects, underscores that this isn’t a medication everyone completes, and stopping is sometimes the right call.
What the iPLEDGE Program Means for Your Accutane Experience
Every isotretinoin prescription in the United States is dispensed through the iPLEDGE REMS program, a system that requires registration of patients, prescribers, and pharmacies. For patients who can become pregnant, this means monthly pregnancy tests, documented use of two forms of contraception, and a narrow window to pick up each month’s prescription. The program exists because of the teratogenic risk, and while it has been criticized for being burdensome, it has also prevented countless cases of isotretinoin-exposed pregnancies since its implementation. Recent FDA-mandated changes, following years of advocacy by the American Academy of Dermatology, have loosened some of the most frustrating requirements.
The 19-day lockout waiting period for patients who missed their initial seven-day prescription pickup window has been removed. Home pregnancy testing is now allowed after the first two office-based tests. And for patients who cannot become pregnant, counseling documentation has been reduced from a monthly requirement to enrollment only. These are meaningful quality-of-life improvements, though the FDA has noted that full implementation may take a year or more. If your pharmacy or dermatologist’s office hasn’t updated their procedures yet, it’s worth asking about these changes directly.
Accutane Cost and Access in 2025 and Beyond
Cost remains a real barrier for some patients, though it’s lower than many expect. Generic isotretinoin can run as low as approximately $40 per month with GoodRx coupons, which represents an 89% discount off the average retail price of around $364. Without insurance, the average cost is approximately $75 per month, and with insurance, copays tend to land around $25. Those are the medication costs alone, however. Monthly blood work and dermatologist visits add to the total, and for patients without insurance, the cumulative cost of a four-to-five month course including labs and office visits can reach several hundred dollars or more.
Looking ahead, the trajectory is encouraging. The iPLEDGE reforms are reducing the bureaucratic friction that caused patients to miss doses or abandon treatment. Research continues to refine our understanding of which side effects are genuinely caused by the drug versus coincidental. And generic competition keeps the price accessible for most patients. For the roughly one million Americans prescribed isotretinoin each year, this remains one of the most effective treatments in all of dermatology, a drug capable of producing long-term remission of severe acne when nothing else has worked. The side effects are real, sometimes uncomfortable, and occasionally serious, but for the majority of patients who complete their course, the outcome is clear skin and a closed chapter on years of struggling with acne.
Conclusion
Isotretinoin side effects are widespread but mostly predictable. Dry lips affect about 90% of patients, dry skin follows close behind at 70%, and joint pain, back pain, and lipid changes each hit more than one in five users. The treatment timeline follows a recognizable pattern: reduced oiliness in the first two weeks, a potential purge in weeks two through four, meaningful improvement by months two and three, and clearance for most patients by month four or beyond. Serious risks, especially birth defects and the complex relationship with psychiatric symptoms, require genuine vigilance and consistent monitoring. The practical takeaway is preparation. Stock up on lip ointment and gentle moisturizers before you start.
Expect the purge and don’t panic. Keep every blood work appointment. Track your mood honestly and report changes to your dermatologist. Understand that the iPLEDGE program, while sometimes frustrating, exists for legitimate safety reasons and is getting easier to navigate. And know that 86.2% of patients in recent research expressed satisfaction with their treatment. Isotretinoin is not a casual prescription, but when severe acne has resisted everything else, it remains the most effective option available, and going in with clear expectations makes the process far more manageable.
Frequently Asked Questions
How long does the Accutane purge last?
The initial acne flare typically occurs during weeks one through four of treatment and may worsen your acne for one to two months before improvement begins. Not every patient experiences a purge, and severity varies. If the flare is extreme, your dermatologist may temporarily add other medications to manage it.
Does Accutane cause depression?
The FDA added a black box warning in 2005 for depression, suicidal thoughts, aggression, and psychosis. UK data through 2017 documented 1,207 psychiatric adverse reactions out of 5,577 total reports. However, repeated high-quality meta-analyses have not confirmed a direct causal link. Severe acne itself is associated with depression, making the relationship difficult to isolate. Monitor your mood closely and report any changes.
How much does Accutane cost without insurance?
Generic isotretinoin averages about $75 per month without insurance. With GoodRx coupons, the price can drop to roughly $40 per month. With insurance, copays are typically around $25. Factor in additional costs for monthly blood work and dermatologist visits.
Can I exercise while taking Accutane?
Yes, but joint pain and back pain each affect more than 20% of patients. Some people continue their normal routines with manageable discomfort, while others benefit from switching to lower-impact activities like swimming or cycling during treatment. Listen to your body and discuss activity modification with your dermatologist if pain becomes significant.
How long after stopping Accutane do side effects last?
Most common side effects like dryness taper off gradually over two to four months after the last dose, since the drug continues working during that period. However, some rare side effects, particularly certain cases of sexual dysfunction, have been reported to persist longer. Birth control must be continued for at least one month after stopping due to the teratogenic risk.
What blood tests are required during Accutane treatment?
Monthly blood work typically includes a lipid panel to check triglycerides and cholesterol, liver function tests, and for patients who can become pregnant, a pregnancy test. Up to 15% of patients show liver test abnormalities, and mild lipid increases are common. These tests allow your dermatologist to catch problems early and adjust your dose if needed.
