Accutane (isotretinoin) works best when you pair it with the right foods, skincare, and a few targeted supplements while avoiding substances that amplify its side effects. The most important thing to take with every dose is a meal containing fat, ideally around 50 grams, because the drug absorbs poorly on an empty stomach. Beyond that, what you put on your skin and into your body over the course of treatment can make a real difference in how you feel.
Take It With a High-Fat Meal
Isotretinoin is fat-soluble, meaning it hitches a ride into your bloodstream alongside dietary fat. The FDA-studied standard for optimal absorption is a meal with roughly 50 grams of fat. That’s not a number you need to hit precisely every time, but it gives you a target. A meal with avocado, eggs, cheese, nuts, or olive oil gets you there easily. Two tablespoons of peanut butter on toast with a glass of whole milk, for instance, puts you in the right range.
Taking your capsule without food, or with just a piece of fruit, means a significant portion of the drug passes through you without being absorbed. You’re essentially wasting doses. Make it a habit: Accutane goes with your biggest meal of the day.
Fish Oil for Triglycerides and Dryness
One of the most useful supplements to take during treatment is fish oil. Isotretinoin commonly raises triglyceride levels (a type of blood fat your doctor monitors with lab work) and causes widespread dryness. A randomized controlled trial published in the Journal of the American Academy of Dermatology found that taking 1 gram of fish oil daily alongside isotretinoin led to smaller increases in triglyceride levels and better skin hydration compared to isotretinoin alone. The fish oil group also experienced less mucocutaneous dryness, the chapped lips and dry skin that make treatment uncomfortable.
Standard fish oil capsules from any pharmacy work fine. Look for one providing about 1,000 mg of combined EPA and DHA, the active omega-3 fatty acids.
What to Avoid: Vitamin A and Tetracyclines
Isotretinoin is a derivative of vitamin A, so taking additional vitamin A supplements on top of it creates a risk of toxicity. Preformed vitamin A accumulates in the body, and doses above 10,000 IU daily are considered potentially dangerous. Many multivitamins contain preformed vitamin A, so check the label. If your multivitamin lists retinyl palmitate or retinyl acetate, switch to one without it, or skip the multivitamin entirely during treatment. Beta-carotene (a vitamin A precursor found in vegetables) is less concerning because the body converts it on demand, but there’s no reason to supplement it either.
Certain antibiotics are also off-limits. Tetracycline-class antibiotics, commonly prescribed for acne themselves, should not be combined with isotretinoin. Both drugs independently raise the risk of a condition called pseudotumor cerebri, where pressure builds inside the skull and mimics the symptoms of a brain tumor: severe headaches, vision changes, and nausea. Using both simultaneously increases that risk further. If you’ve been taking doxycycline or minocycline for acne, your prescriber will stop them before starting isotretinoin.
Alcohol and Your Liver
Isotretinoin is processed by the liver, and your doctor will order blood tests throughout treatment to check liver enzymes and lipid levels. Alcohol adds stress to the same organ. The safest approach is to avoid alcohol entirely during your course. If that feels unrealistic, keep consumption minimal and infrequent, and be honest with your prescriber about your habits so they can monitor your bloodwork accordingly. Heavy or binge drinking while on isotretinoin is a genuine risk for liver damage.
Lip Balm and Moisturizers That Actually Work
Nearly everyone on isotretinoin develops dry, cracked lips, often within the first two weeks. The key is using products with occlusive ingredients that physically seal moisture in. Petrolatum (the active ingredient in Vaseline and Aquaphor) is the gold standard. Apply it to your lips constantly, not just when they feel dry. Keeping a tube in every pocket, bag, and nightstand makes a difference. Some studies have also looked at products containing panthenol (provitamin B5), which helps repair the skin barrier and reduce water loss. Lip balms with wax-based formulas or flavored varieties without occlusives tend to be disappointing.
For your face and body, the goal is the same: rebuild and protect a skin barrier that isotretinoin is actively thinning. A well-designed moisturizer combines three types of ingredients:
- Humectants like glycerin, hyaluronic acid, and panthenol, which pull water into the skin
- Occlusives like petrolatum, mineral oil, or silicone derivatives, which lock that water in
- Emollients like jojoba oil or squalane, which smooth and soften
CeraVe, Vanicream, and La Roche-Posay Cicaplast are popular choices among isotretinoin users because they check all three boxes. Apply moisturizer to damp skin right after washing for the best results.
What to Drop From Your Skincare Routine
Isotretinoin dramatically reduces your skin’s ability to tolerate irritation. Anything designed to exfoliate, resurface, or “treat” acne should be shelved for the duration. That includes retinol serums, glycolic acid, salicylic acid, benzoyl peroxide, vitamin C at high concentrations, and physical scrubs. Harsh cleansers and alkaline soaps strip the skin’s natural buffering capacity, which is already compromised during treatment. Switch to a gentle, fragrance-free cleanser with a slightly acidic or neutral pH. Overwashing is just as damaging as using the wrong products, so washing your face twice a day is plenty.
Sunscreen Is Non-Negotiable
Isotretinoin makes your skin significantly more sensitive to UV radiation. Sunburns happen faster and more severely than you’re used to. Use a broad-spectrum sunscreen with SPF 30 at minimum, though SPF 50 is the better target. Apply it generously to all exposed skin about 15 to 20 minutes before going outside, and reapply every two hours, or more often if you’re sweating or swimming.
Sunscreen alone isn’t enough on high-exposure days. Protective clothing made from tightly woven fabric, a wide-brimmed hat, and UV-blocking sunglasses all reduce your risk. The sun’s intensity peaks between 10 a.m. and 4 p.m., so staying in the shade during those hours helps more than any product. This heightened photosensitivity lasts the entire course of treatment and can persist for a short time after you stop.
Putting It All Together
Your daily Accutane routine looks something like this: take your capsule with a meal that includes a good amount of fat. Take a fish oil supplement with that same meal. Wash your face with a gentle cleanser, apply a rich moisturizer, and layer sunscreen on top before heading out. Keep an occlusive lip balm within arm’s reach at all times. Skip the vitamin A supplements, lay off alcohol, and shelve any active skincare ingredients until your course is finished. These habits won’t eliminate every side effect, but they meaningfully reduce the dryness, protect your liver, and ensure your body actually absorbs the medication you’re taking.
