Can you drink on Accutane? Alcohol and isotretinoin

Many people search whether they can drink alcohol while taking isotretinoin, the drug many still call Accutane. The sources agree on the direction and differ on the detail. The NHS says it is best not to drink while taking it. The FDA label names heavier drinking as a risk factor for a blood fat problem the drug is known to cause, and it lists liver inflammation among its warnings. This guide sets out exactly what each source says. For the drug itself, see the Accutane guide. For drinking and acne when you are not taking isotretinoin, see alcohol and acne.

Skinli gives general education and is not a doctor. Isotretinoin is prescribed and monitored by a doctor, who sees your blood test results and can tell you what applies to you. If you have not yet seen anyone about severe acne, start with when to see a dermatologist for severe acne.

What each source says

Source	What it says about alcohol
NHS, reviewed June 2026	"It's best to not drink alcohol while taking isotretinoin because it could cause liver problems"
FDA label, August 2026	Names "increased alcohol intake" among the factors that put a patient at higher risk of high triglycerides, and asks for more frequent blood fat checks in those patients
FDA label, August 2026	Says some patients lowered raised triglycerides while continuing treatment by losing weight and restricting dietary fat and alcohol
FDA label, August 2026	Asks for blood fat tests to be done at least 36 hours after drinking alcohol
MedlinePlus	Asks patients to tell their doctor if they drink or have ever drunk large amounts of alcohol

The labels on DailyMed give no fixed limit. The NHS page describes UK advice. Where the two differ in strength, Skinli follows the stricter NHS advice, and your prescriber can tell you whether any drinking is acceptable for you.

Alcohol and blood fats

Triglycerides are a type of fat in the blood. The FDA label reports that in clinical trials isotretinoin caused a marked rise in triglycerides in 25 percent of patients, a fall in "good" HDL cholesterol in 15 percent, and a rise in total cholesterol in 7 percent. Triglycerides above 800 mg/dL have been reported. These changes reversed after the drug was stopped.

The label lists the patients at higher risk of this problem: people with diabetes, obesity, increased alcohol intake, or a personal or family history of trouble processing fats. For them, it recommends more frequent blood fat checks, and it says the drug should be stopped if high triglycerides cannot be controlled.

The label also reports acute pancreatitis, a painful inflammation of the pancreas, in patients with high or normal triglyceride levels, and says it has in rare cases been fatal. The Medication Guide tells patients to stop the drug and call right away for severe upper belly pain, swelling of the belly, nausea and vomiting, or fever.

Alcohol and the liver

The FDA label reports hepatitis, which is inflammation of the liver, with isotretinoin. It says mild to moderate rises in liver enzymes were seen in an estimated 15 percent of patients in clinical trials, some of which returned to normal with a lower dose or with continued treatment. If the enzymes do not return to normal, or hepatitis is suspected, the label says to stop the drug.

The NHS gives liver problems as its reason to avoid alcohol. The Medication Guide lists the signs to report right away: yellowing of the skin or the whites of the eyes, pain on the right side of the belly, dark urine, and bleeding or bruising more easily than normal.

Blood tests and the 36-hour rule

The label asks for blood fat tests before treatment and during it, under fasting conditions, and says at least 36 hours should pass after drinking alcohol before the test. Liver tests are done before and during treatment as well. A 2016 review in JAMA Dermatology found that the average lab changes on standard doses stayed below the level its authors set as high risk, and that the share of patients with abnormal results was low. If you drank in the two days before a scheduled blood test, tell the lab or your prescriber, because the label asks for 36 hours without alcohol before the test.

The how to get Accutane guide explains the full testing schedule.

What the blood tests look at

The label lists the lab values that can change during treatment. The two groups that alcohol can also affect are:

Test group	What it measures	What the label reports with isotretinoin
Lipid profile (blood fats)	Triglycerides, total cholesterol, LDL cholesterol and HDL, the "good" cholesterol	Triglycerides, cholesterol and LDL can rise, and HDL can fall
Liver tests	Enzymes called ALT, AST, GGT and alkaline phosphatase, and bilirubin	These values can rise, and hepatitis has been reported

The label says the blood fat response usually shows within 4 weeks of starting. Ask your prescriber for your numbers at each visit, and ask what they would need to see before they said yes to a drink.

When the prescriber may change the plan

The label gives the prescriber several options when results come back high. For triglycerides, it describes patients who brought levels down by losing weight and cutting back on dietary fat and alcohol while staying on the drug, and others through a lower dose. It says to stop the drug if high triglycerides cannot be controlled, or if symptoms of pancreatitis appear. For the liver, it says some raised enzymes returned to normal with a lower dose or with continued treatment, and that the drug should be stopped if they do not return to normal or if hepatitis is suspected. Each of these is a decision for your prescriber, based on your own results.

Warning signs to act on

These signs, from the Medication Guide, need a call to your prescriber right away, whether or not you have been drinking:

Signs	What they can mean
Severe upper belly pain, swollen belly, nausea and vomiting, fever	Inflammation of the pancreas
Yellow skin or eyes, pain on the right side of the belly, dark urine, bleeding or bruising easily	Liver problems
Unusual thirst, passing urine more than usual	Blood sugar problems

Night driving

The label says isotretinoin can reduce night vision, sometimes suddenly, and warns patients to be careful driving or operating any vehicle at night. The Medication Guide says not to drive at night until you know whether the drug has affected your vision. The NHS says that if you feel dizzy, wait until the dizziness stops before you drive.

If you drink regularly now

Tell your prescriber how much and how often you drink, honestly, before you start. MedlinePlus asks for this, including past heavy drinking. It is part of how the prescriber judges your risk of high triglycerides and liver problems, and it may change how often you have blood tests.

Before an event: questions to ask

If a wedding, a holiday or a party falls during treatment, ask your prescriber:

1. Given my latest blood fat and liver results, is any alcohol acceptable for me?
2. If so, how much, and should I skip it close to a blood test?
3. Are there signs after drinking that mean I should call you?

Other things to avoid during treatment

The label lists vitamin A supplements, because isotretinoin is closely related to vitamin A, and tetracycline antibiotics, because together they raise the risk of pressure inside the skull. MedlinePlus adds St. John's wort, which can make hormonal birth control fail. The Medication Guide says not to take other medicines or herbal products without talking to your prescriber. The American Academy of Dermatology lists skin care ingredients to avoid, including retinol, benzoyl peroxide, vitamin C products and exfoliating acids.

After the last dose

The label gives isotretinoin a half-life of 21 hours, and 24 hours for its main breakdown product. A half-life is the time it takes for half of a drug to leave the blood. The blood fat changes reversed after the drug was stopped in trials. The program rules that last longer, for 1 month after the last dose, are about pregnancy and blood donation; the Accutane and pregnancy guide explains them.
