Depression, inflammatory bowel disease and ulcerative colitis are the three most reported adverse events of Accutane, making up just over 40% of all isotretinoin side effects, according to the FAERS Database.

Updated Boxed Warnings for Accutane

As of July 2024, isotretinoin has one boxed warning that patients who are or might become pregnant must not use the drug because of the possibility of major birth defects. A boxed warning is the highest safety-related warning that the FDA can assign a medication; it indicates an increased risk of serious or life-threatening side effects.

Did You Know?
The popular brand-name acne medication Accutane is no longer available in the United States, but you can still get the generic version called isotretinoin. It's available under different brand names, such as Absorica, Amnesteem, Claravis, Myorisan, Sotret, and Zenatane.

There is an extremely high risk of a fetus developing life-threatening birth defects at any stage of pregnancy if the parent takes any amount of isotretinoin, even just one dose.

According to the drug label, documented birth defects following isotretinoin exposure include abnormalities of the facial features, central nervous system, internal organs and glands. There have also been cases of IQ scores being less than 85. Reports also indicate an increased risk of spontaneous abortion (miscarriage) and premature births.

Fetal Abnormalities
  • Anotia (no external ear)
  • Cardiovascular abnormalities
  • Cerebellar malformation (brain defect that can affect motor control)
  • Cerebral abnormalities
  • Cleft palate
  • Cranial nerve deficit (can cause motor and sensory issues)
  • Eye abnormalities including microphthalmia (one or both eyes are undersized)
  • Hydrocephalus (excess fluid in the brain)
  • Microcephaly (undersized brain)
  • Micropinna (small external ears and small ear canal)
  • Parathyroid hormone deficiency
  • Skull abnormality
  • Small or absent external auditory canals
  • Thymus gland abnormality (the thymus gland is associated with creating white blood cells)

In some cases, birth defects resulting from isotretinoin use caused death. According to the black box warning, those who become pregnant while taking isotretinoin must discontinue its us immediately. Additionally, the provider should advise their patient to seek evaluation and counseling from an obstetrician-gynecologist with expertise in reproductive toxicity.

iPLEDGE Requirement for Accutane

Due to the increased risk of fetal defects with the use of Accutane, a rigorous program called iPLEDGE began in 2006 to reduce fetal exposure to isotretinoin. All patients who can become pregnant are required to sign an iPLEDGE agreement and take a monthly pregnancy test while taking Accutane.



Common Accutane Side Effects

Skin irritation, dryness and sun sensitivity are common Accutane side effects. These tend to be mild and usually resolve on their own within a few weeks.

Common Side Effects
  • Chapped lips
  • Decreased night vision
  • Dry and itching skin
  • Headache
  • Increased sensitivity to the sun
  • Intestinal symptoms, such as inflammatory bowel disease and colitis
  • Irritation of the eyelids and eyes
  • Joint and muscle pain
  • Mild nosebleed
  • Rash
  • Temporary hair thinning
  • Urinary symptoms, such as blood in urine

Some common side effects, such as intestinal symptoms, joint pain and vision complications can cause long-term damage even after stopping Accutane. While it is good practice to notify your health care provider if you experience any adverse reactions, it is especially important to keep your provider informed of any symptoms that may be permanent.

Managing Common Accutane Side Effects

Moisturizing can help alleviate dryness, a common side effect of Accutane. Try applying moisture-enhancing products such as lotions, lip balms, eye drops and Vaseline as needed in areas where you experience dryness.

A diet that promotes digestive health may help alleviate gastrointestinal issues caused by Accutane. Leafy greens and probiotics are generally good for gut health, but your doctor can help you determine the best diet for your needs.

Some over-the-counter pain relievers, such as ibuprofen, may help with pain. However, not all pain relievers are appropriate. For example, it is important to limit your intake of liver-stressing substances such as acetaminophen (tylenol) and alcohol. If you consume these substances while on Accutane, you may increase your chances of liver damage.

Serious Side Effects of Accutane

Accutane may cause serious neurological, psychological and gastrointestinal side effects. Additional serious side effects may include decreased red or white blood cells, blood sugar problems, allergic reactions such as hives or trouble breathing, skin problems such as peeling, blistering, rash with fever and conjunctivitis (pink eye).

Report any serious side effects you experience to your doctor. You may also consider reporting to the FDA’s MedWatch Adverse Event Reporting program. Some patients who received Accutane treatment filed lawsuits against Roche, the drug’s manufacturer, in 2014. However, as of July 2024, Drugwatch is not aware of lawyers accepting these cases at this time.

Accutane and Mental Health

Depression, psychosis and suicide are possible serious side effects of Accutane.

Signs of Depression or Psychosis
  • Becoming angry, aggressive or irritable
  • Changes to your weight or appetite
  • Difficulty concentrating
  • Feeling like you have no energy
  • Hallucinations
  • Having feelings of worthlessness or guilt
  • Losing interest in activities you once enjoyed
  • Sleep disturbances
  • Suicidal ideation

As soon as any signs of depression or psychosis begin, contact your health care provider to determine what your next steps should be. They will likely discontinue your treatment with Accutane. You may need additional treatment beyond stopping the medication.

Serious Brain Problems with Accutane

Accutane can cause increased pressure in the brain (pseudotumor cerebri), which can lead to permanent loss of eyesight and, in rare cases, death. Severe headache, seizures, stroke, nausea and vomiting are all potential symptoms of increased brain pressure. Inform your doctor as soon as possible about these symptoms.

Accutane-Related Organ Problems

Symptoms such as severe stomach or chest pain, diarrhea, bloody stools, dark urine, difficulty swallowing and yellowing of the skin or eyes could indicate organ damage. These symptoms could indicate damage to the liver, pancreas, bowel and esophagus.

You should immediately inform your doctor of any of these symptoms. The damage might be permanent even after stopping Accutane, but swift treatment can increase your chances of recovery.

Case Study: Kamie Kendall, Accutane and Ulcerative Colitis
Kendall was prescribed Accutane for the first time at age twelve. During her initial course and three subsequent courses of Accutane for two years, she did not experience any gastrointestinal symptoms. At the time, her doctor was unaware of the potential risk of inflammatory bowel disease (IBD), and the patient brochure Kamie received only warned of general gastrointestinal issues.

Diagnosis and Symptoms
Three years after first taking Accutane, while no longer using the drug, Kendall was hospitalized with bloody diarrhea and abdominal pain, leading to a diagnosis of ulcerative colitis. Her symptoms, including frequent and often bloody bowel movements and pain, are characteristic of this chronic condition. Despite ongoing treatment, Kendall’s symptoms have persisted intermittently, as is typical with ulcerative colitis.

Conclusion
Although she developed ulcerative colitis after multiple courses of Accutane, the exact cause remains uncertain, further complicated by a family history of the disease. Kamie’s experience highlights the importance of continuous safety evaluations and clear communication of potential medication risks.
