isotretinoin
Isotretinoin is used to treat nodular acne that can't be cleared up by other acne treatments, including antibiotics. It's taken by mouth twice daily, typically for 4 to 5 months at a time. Because of the risk of serious birth defects, people who can get pregnant need to take pregnancy tests and use birth control before, during, and after treatment. Some common side effects include dry lips, dry skin, back pain, and dry eye. While isotretinoin is no longer available as brand name Accutane, you can still find it under other brands (e.g., Claravis and Amnesteem) and also as lower-cost generics.

Pharmacist tips for Isotretinoin
- Your skin might look worse at first before it gets better. Keep taking isotretinoin as prescribed to you, and discuss with your provider if your progress concerns you.
- If you miss a dose, just skip that dose. Don't take two doses at the same time or extra doses.
- Isotretinoin can make your skin more sensitive to sunlight. Wear sunscreen and protective clothing when going out. Avoid prolonged sun exposure and tanning beds.
- You shouldn't drive at night until you know how isotretinoin affects your vision.
- Your provider might order blood tests for you regularly while you're taking isotretinoin. This is because this medication can cause side effects such as higher cholesterol levels or liver problems. It's important that you go to your appointments because the test results can help your provider decide whether isotretinoin is still safe for you to take.
- Though not common, isotretinoin can affect your thoughts and mood. Stop taking isotretinoin and call your healthcare provider if you notice signs and symptoms of depression or thoughts of self-harm.
- Don't take other medications or herbal products unless you talk to your healthcare provider. Even certain vitamins (e.g., vitamin A) can interact with isotretinoin and be dangerous for you.
- You shouldn't donate blood while taking isotretinoin and for 1 month after stopping the medication. Someone who's pregnant could receive your donated blood that still has the medication in it, which can cause birth defects in their unborn baby.
More tips for people who can get pregnant:

- You must not to get pregnant for 1 month before starting, during, and 1 month after treatment with isotretinoin. Your provider will require you to get pregnancy tests done throughout your treatment.
Common questions about Isotretinoin
Yes, isotretinoin is the generic medication for brand Accutane. Keep in mind that Accutane is no longer available in the United States. But other brands of isotretinoin still are, including Claravis and Amnesteem.
No, these two medications aren't the same. Both isotretinoin and tretinoin are prescription medications made from vitamin A and used to treat acne. One main difference is how you take them. Isotretinoin is an oral medication that's taken by mouth, typically twice daily. Tretinoin is a topical medication that's applied to the skin daily or every other day. Another important difference is side effects. Both medications can cause skin-related side effects such as dry skin and skin that's more sensitive to the sun. But isotretinoin is known to cause serious birth defects and everyone who takes this medication must enroll in a safety program called iPLEDGE. Tretinoin isn't known to cause the same level of risk, but your provider will likely still recommend that you avoid using tretinoin during pregnancy to prevent the risk of harm.
You might notice improvements in your skin after taking isotretinoin for about 4 weeks. But it'll take longer to see complete results from this medication. If your acne didn't clear up as much as you'd like after a full treatment course, talk with your provider. If appropriate, they might recommend that start you on a second isotretinoin course at least 2 months later at a later date.
A treatment course of isotretinoin usually lasts for 15 to 20 weeks (around 4 to 5 months). Most people can expect to see clearer skin after that time, but a few people might need another round of treatment. You should take this medication exactly as prescribed by your healthcare provider.
The effects of isotretinoin can last in your system for a month after stopping it. For this reason, limit drinking alcohol during your treatment course and for a month after in order to protect your liver. If you develop symptoms such as yellowing of your skin or eyes, abdominal pain, and dark urine, get medical help right away because these are signs of liver damage.
Some of the most common side effects of isotretinoin include dry skin, chapped lips, dry eyes, and nosebleeds. You can ease these side effects by regularly applying a skin moisturizer, lip balm, and lubricating eye drops. It also helps to stay hydrated by drinking water throughout the day. Because many of the side effects of isotretinoin are skin-related, try to avoid harsh skin products and treatments, such as microdermabrasion, laser treatments, and waxing because these can further irritate your skin. Talk with your provider if you've more questions about easing a particular side effect.
iPLEDGE is a special medication safety program for isotretinoin. The purpose of this program is to prevent pregnant people from being exposed to isotretinoin. This is because isotretinoin can cause serious birth defects if taken by mothers during pregnancy. Everyone who takes this medication must register with iPLEDGE, even if they can't get pregnant. As a part of iPLEDGE, people who can get pregnant must take pregnancy tests and use 2 forms of birth control before, during, and after treatment with isotretinoin.

Risks and warnings for Isotretinoin
Isotretinoin can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Harm to unborn baby
Isotretinoin can cause harm to unborn babies, such as birth defects, unexpected abortions, and premature births. Due to this risk, isotretinoin is only available through a special program (iPLEDGE) that you, your healthcare provider, and your pharmacy must sign up for. You can sign up for this program after discussing the risks and benefits with your healthcare provider. People who can get pregnant must use two forms of contraception (birth control) for 1 month before starting, during, and for 1 month after stopping treatment. You'll also need to have regular pregnancy tests while taking isotretinoin.
Depression and thoughts of self-harm
- Risk factors: History of depression or other mental health condition
Isotretinoin can cause depression, delusions, hallucinations, aggressive behavior, and suicidal thoughts or behavior. Talk to your healthcare provider as soon as possible if you or anyone around you notice any unusual changes in your mood or behavior, especially during the first few months of treatment or when the dose changes.
Higher pressure in the brain
- Risk factors: Taking tetracycline medications at the same time
Isotretinoin can raise the pressure in your brain. This can lead to permanent loss of eyesight, and in rare cases, death. Avoid taking or using any tetracycline antibiotics (e.g., minocycline, doxycycline, clindamycin) with isotretinoin, since this combination raises your risk. Call your healthcare provider right away if you experience bad headache, blurred vision, dizziness, nausea or vomiting, seizure, and stroke, as these might be signs of higher brain pressure.
Serious skin reaction
Isotretinoin can cause serious and life-threatening skin reactions, such as Stevens-Johnson syndrome (SJS). Go to the emergency room as soon as possible if you get a bad blistering rash all over your body with a very high fever and you can't breathe.
Inflammation of the pancreas
Inflammation of your pancreas (pancreatitis) can happen in people who take isotretinoin. Call your healthcare provider right away if you experience severe upper stomach pain, swelling of your stomach, nausea or vomiting, and fever. These might be signs of problems in your pancreas.
High cholesterol and triglycerides
- Risk factors: Diabetes | Larger body size | Drinking alcohol regularly
Isotretinoin can raise the amount of cholesterol and triglycerides (a type of fat) in your blood. Your provider might order blood tests regularly to check your cholesterol and triglyceride levels. If your levels are too high, your provider might ask you to stop isotretinoin. These levels usually go back their normal range once you stop the medication.
Hearing problems
Stop using isotretinoin and call your healthcare provider if your hearing gets worse or if you hear ringing in your ears. Your hearing loss may be permanent, meaning it may continue even after stopping the medication.
Liver problems
Isotretinoin can lead to liver problems, like inflammation (hepatitis). Your healthcare provider will order lab tests to check that your liver is healthy before and during treatment with isotretinoin. Call your healthcare provider right away if you experience yellowing of your skin or the whites of your eyes, pain on the right side of your stomach, dark urine, and bleeding or bruising more easily than normal. These can be signs of liver damage.
Inflammation of the gut
In some rare cases, isotretinoin can cause inflammatory bowel disease in people without a history of stomach issues. People who have stomach pain, rectal bleeding, or severe diarrhea should stop isotretinoin right away and let their healthcare provider know.
Bone fractures and muscle pain
- Risk factors: Weaker bones or bone-related conditions | Eating disorder called anorexia | Taking seizure medications or corticosteroids | Problems with vitamin D breakdown | Taking isotretinoin for a long time
Isotretinoin can cause muscle weakness, joint and bone pain, back pain, weakened bones, and bone fractures. The risk is higher if you are 65 years or older, currently have bone or joint problems, or are taking other medications that can weaken your bones. Talk to your provider about ways to stop bone fractures.
Eye problems
- Risk factors: History of eye problems
Isotretinoin can worsen vision, dry the eyes, and make it harder to wear contact lenses. Be careful driving, especially at night, until you know how this medication affects you. If you notice changes in your vision, stop taking isotretinoin and get an eye exam as soon as possible.
