Isotretinoin

Isotretinoin is a medicine used to clear acne.

This medicine works by unclogging skin pores and shrinking oil glands. It can take 6 or more months to fully treat acne. If acne returns after treatment is done, it usually is not as bad as it was before.

Common side effects include dry skin, nose, mouth, eyes, and lips. Some people also feel more tired than usual, sunburn more easily, have problems with night vision, or lose more hair than usual.

Isotretinoin can have serious risks, especially during pregnancy. Just one dose can cause severe birth defects or miscarriage. It can also cause severe headaches, arm or leg pain, or changes in your liver or blood. When taking this medicine, you will have regular blood tests to see how it is affecting your liver, and to check your cholesterol and triglyceride levels. Testing is usually done every month.

Some reports state that taking this medicine may increase the risk of getting inflammatory bowel disease. But experts don't have enough information to know if this is true.

There may be a link between this medicine and depression or other serious mood problems. Your doctor will want to know if you have mood changes.

Isotretinoin (such as Amnesteem, Claravis, or Zenatane) is a powerful medicine that's usually prescribed for severe acne that can't be cleared up with other medicines. It's typically taken for 4 to 5 months. If acne returns after treatment, you may be able to take another round of medicine.

This medicine unclogs skin pores, shrinks oil glands, and decreases bacteria and inflammation. It can reduce the scarring caused by acne. It may also help if acne is causing distress. There's a link between acne and depression and other mental health concerns.

But isotretinoin can cause side effects. And it has serious risks, especially during pregnancy.

What are the serious risks during pregnancy?

Taking isotretinoin even for a short time during pregnancy can cause severe birth defects or miscarriage.

Before anyone can start treatment with isotretinoin, they have to enroll in a program called iPLEDGE. Your doctor can explain this program to you. Among other things, it may require you to:

• Use two forms of birth control before, during, and after your treatment.
• Take pregnancy tests before, during, and after treatment if you're able to get pregnant.
• Have monthly doctor visits while you're taking this medicine. These may be in-person or virtual care (telehealth) visits.

What are some possible side effects?

Other side effects include dry skin, nose, mouth, eyes, and lips. Some people also feel more tired than usual, sunburn more easily, have problems with night vision, or lose more hair than usual.

These side effects can usually be treated with over-the-counter products like moisturizers, sunscreen, and artificial tears. If you have dry eyes while taking this medicine, you may have to wear glasses instead of contact lenses.

This medicine may also cause headaches, muscle pain, or changes in your liver or blood. You'll have blood tests to see how it's affecting your liver and to check your cholesterol and triglyceride levels.

There may be a link between this medicine and depression or other serious mood problems. Your doctor will want to know if you have mood changes.

Some reports suggest that isotretinoin may increase the risk of inflammatory bowel disease. But experts don't have enough information to know if this is true.

How can you decide if you should take this medicine?

You may want to take isotretinoin if:

• You have acne that doesn't get better after several months of treatment with other medicines.
• You have acne that's causing scarring.
• Acne causes you to have anxiety, low self-esteem, or depression.

You may not want to take this medicine if:

• You can control your acne with other medicines or treatments.
• There is any chance that you could get pregnant.
• You want to avoid the side effects.

Your doctor can help you weigh the pros and cons of this medicine so you can decide what's right for you.

• Do not take this medicine if there is any chance you are pregnant.
• Protect against pregnancy if you are a teen or woman in your childbearing years. Use two forms of birth control if you have sex while you are taking isotretinoin and for 1 month after you stop taking the medicine.
• Do not take vitamin A when using this medicine. It can make side effects worse.
• Use a vaporizer or humidifier to add moisture to your bedroom. Follow the directions for cleaning the machine.
• Relieve eye dryness with eyedrops, such as preservative-free Artificial Tears.
• Relieve skin dryness with lotion. Apply it to damp skin right after you shower. Use lip balm.
• Relieve mouth dryness with sugar-free gum or candy such as lemon drops. Drink fluids throughout the day. Try rinsing your mouth a lot and taking small sips of water often.
• Relieve nose dryness with saline (saltwater) nasal washes. You can buy saline nose drops at a grocery store or drugstore. Or you can make your own at home by adding 1 teaspoon of salt and 1 teaspoon of baking soda to 2 cups of distilled water. If you make your own, fill a bulb syringe with the solution, insert the tip into your nostril, and squeeze gently. Blow your nose.
• Protect your eyes and skin from the sun. Always wear sunscreen on exposed skin. Make sure to use a broad-spectrum sunscreen that has a sun protection factor (SPF) of 30 or higher. Use it every day, even when it is cloudy.
• Take your medicine exactly as prescribed. Call your doctor if you think you are having a problem with your medicine.
