Dr. Amit Om, board-certified dermatologist, says that if you are dealing with stubborn breakouts and feel like you are out of options—topicals aren’t cutting it, but the idea of taking full-dose Accutane sounds overwhelming—there’s an option that might be worth a look: low-dose Accutane.

Known for being one of the most effective acne treatments out there, Accutane has come a long way from its high-dose, high-side-effect reputation.

Research shows that low doses of Accutane can still make a big difference, especially for people dealing with acne that causes severe scars. The bonus? Fewer side effects and a treatment plan that’s often easier to stick with.

New research supports the idea that you can get good results without needing the maximum dose and low-dose regimes are helping more people find that sweet spot between results and comfort¹ ² .

In this article, you’ll get a closer look at how low-dose Accutane works, what the research says, and what to keep in mind if you’re considering this treatment.

What is the average dose of Accutane?

Dr. Om, says that for someone weighing between 150 and 200 pounds (60-90 kg), the typical Accutane (isotretinoin) dose ranges from 40 to 80 mg per day, based on the standard AAD recommended dosing of approximately 1 mg per kg of body weight per day³.

Can you take a low-dose of Accutane (isotretinoin)?

Yes! Dr. Om says that taking a low dose of Accutane (about half the usual amount based on your weight) can indeed reduce acne breakouts a lot, however, the acne is more likely to return in the long run compared to standard doses.

Although low-dose Accutane has been explored to some extent, Dr. Om says there aren’t enough studies to confirm its full effectiveness⁴ ⁵ ⁶. Still, if the patient is aware of the risk of higher relapses, low-dose Accutane treatment may be a reasonable option to avoid the side effects a full-dose regime brings.

What does a low-dose (micro-dose) of Accutane regimen look like?

Dr. Om explains that low-dose Accutane can be taken in two ways: either as a small daily dose or as a standard dose every 2–3 days.

Option 1: Daily low-dose

5–30 mg daily (depending on your weight)
More steady blood levels
Good for moderate acne and people prone to side effects

Option 2: Intermittent dosing

40 mg every 2–4 days (depending on your weight)
Less medication in your system overall
Still helps with oily skin and acne prevention

Accutane low-dose maintenance

Dr. Om says that after acne is under control, patients can adhere to an ultra-low maintenance regimen.

5–10 mg 1–3 times/week
Used to maintain clear skin without harsh side effects

Side effects of low-dose Accutane

Dr. Om says that the side effects of low-dose Accutane are essentially the same as those seen with standard-dose isotretinoin, but they tend to be milder and more tolerable, which is why many dermatologists opt for a low-dose regimen—especially for long-term or maintenance use. Common side effects include dry lips, mild skin dryness, occasional nosebleeds, dry eyes, and increased sun sensitivity⁷. While other effects like fatigue, mild headaches, or changes in blood lipids can still occur, they’re generally less intense and easier to manage at lower doses, making the treatment more comfortable for patients over time.

What Accutane strengths can you buy?

Dr. Om says you can buy the following strengths of Accutane:

5 mg
10 mg
20 mg
30 mg
40 mg

Frequently asked questions about Accutane

What is an Accutane cumulative dose?

Dr. Om says that an Accutane cumulative dose refers to the total amount of isotretinoin taken throughout the entire course of treatment, usually calculated in milligrams per kilogram of body weight (mg/kg). The standard cumulative target is 120–150 mg/kg (or more), which has been shown to significantly reduce the risk of acne coming back. For someone weighing 130–150 pounds (about 59–68 kg), this means the total cumulative dose would range from approximately 7,100 to 10,200 mg, spread out with daily doses over several months depending on how the body responds and what the dermatologist recommends.

What is the starting dose of Accutane?

Dr. Om says he typically starts patients on a lower dose to minimize side effects, then adjusts based on response and tolerance. For someone weighing 130–150 pounds, a common starting dose might be around 30 to 50 mg per day, sometimes split into two smaller doses. The exact dose can vary depending on the severity of the acne and how well the patient tolerates the medication.

Can you take a low dose of Accutane forever?

Dr. Om says that while some people use low-dose Accutane for extended periods, taking it “forever” is not usually recommended due to potential long-term side effects like liver strain, lipid changes, or skeletal issues. However, some dermatologists may prescribe very low maintenance doses (5–10 mg a few times per week) for ongoing skin control under medical supervision. The key is to monitor blood work regularly and assess for any long-term risks with regular follow-ups with the dermatologist.

What would be a micro-dose of Accutane?

Dr. Om says that for someone weighing 130–150 pounds, a micro-dose of Accutane typically means taking 5–10 mg daily, or around 20–40 mg just a few times per week. This is well below the standard daily dose and is often used for maintenance, long-term prevention, or in cases of sensitive skin. While it’s not intended to completely clear severe acne, it can be very effective at gently reducing oil production and inflammation over time—making it a great option for adults dealing with persistent, mild breakouts.

What is considered a high dose of Accutane?

A high dose of Accutane is typically defined as 1 mg/kg/day or higher. For a person weighing 130-150 pounds, that would mean 50 – 70 mg daily. Some treatment protocols may go slightly above this, especially in cases of very severe, scarring acne, but higher doses also increase the risk of side effects and may require more frequent lab monitoring.

Can you take a low dose of Accutane for anti-aging?

Dr. Om says that although there’s emerging interest in using very low doses of Accutane like 5–10 mg a few times a week for potential anti-aging benefits, however, he does not recommend this as the risks outweigh the benefits. If you want to experiment the benefits of prescription retinoids for anti-aging he recommends using tretinoin for wrinkles instead.

Can you take a low dose Accutane for rosacea?

Dr. Om says that low-dose Accutane has been shown to help with papulopustular rosacea (the type with inflammatory red bumps and pimples). However, he explained that doses are usually much lower than those used for acne—often 10 mg every other day or a few times a week. It can reduce oil production, inflammation, and redness, making it a helpful option for rosacea sufferers unresponsive to other treatments.

Can you take a low dose of Accutane long-term?

Yes, Dr. Om says that in some cases he may prescribe low-dose Accutane long-term, especially for adults with chronic, treatment-resistant acne. Doses may range from 5–20 mg daily or every few days. This approach reduces the risk of flare-ups and minimizes side effects, but it should be done under supervision, with periodic lab tests to monitor liver function and lipids.

What is the Accutane maintenance dose?

Dr. Om says that a maintenance dose of Accutane is a small, ongoing dose used after a full course to keep acne from returning. This often looks like 5–10 mg daily or a few times per week. It’s particularly helpful for adult acne patients or those who relapse after stopping treatment. While not always necessary, it can be effective for long-term skin control when monitored properly.

Is 30 mg of Accutane a high dose?

Dr. Om says that 30 mg of Accutane is considered a moderate dose for someone weighing 130–150 pounds, which is lower than the standard high-dose range but still effective for many patients. It balances results and tolerability, making it a common choice for people with mild to moderate acne or those sensitive to side effects.

Is 40 mg of Accutane a high dose?

Dr. Om says that for someone weighing around 130–150 pounds, 40 mg of Accutane is considered a moderate dose. It falls below the typical high-dose threshold making it a common and well-balanced starting point. This dose is often effective while keeping side effects more manageable, and it can be adjusted based on how your skin responds and what your lab results show.

Is 60 mg of Accutane a high dose?

Dr. Om says that for someone weighing 130–150 pounds, 60 mg of Accutane is at the higher end of the typical dosing range. It’s commonly used for treating moderate to severe acne and is generally considered a high dose. While it tends to be effective, it also increases the risk of side effects like dryness, fatigue, and changes in mood or blood work, so regular monitoring is important.

Is 80 mg of Accutane a high dose?

Dr Om says that 80 mg of Accutane is a very high dose, generally reserved for patients who weigh over 180 pounds or have severe, scarring acne. This level of dosing is effective but patients will likely experience dryness and potentially other side effects, thus d requiring close supervision by a dermatologist, including regular blood tests and symptom check-ins.
