Isotretinoin (for Acne)

In some people, the acne may seem to get worse during the first few weeks before improving.

Certain side effects of this medication may happen and may even disappear during treatment. If any of the following effects persist or are severe, consult your doctor. These side effects include:

• Red, cracked and sore lips. 
• Apply lip balm frequently
• Irritated and dry eyes.
• Apply eye-drops or artificial tears to prevent this. Stop the use of contact lenses if irritation persists. 
• Dry skin, sometimes with peeling. 
• Apply moisturiser regularly to manage skin dryness
• Dry mouth 
• Drink more water or suck on sweets
• Dry nose.  Nose bleeding may occur for severe cases.
• Apply white soft paraffin to the lining inside of your nose. If it does not resolve, consult your pharmacist or doctor about decreasing the dose of the medication.
• Increased risk of sunburn
• Avoid staying directly under sunlight for long durations. Use a broad-spectrum sunscreen product with Sun Protection Factor (SPF) of at least 30 and wear protective clothing when you are exposed to direct sunlight.
  

The following uncommon side effects may occasionally occur. Consult your doctor if any of them becomes severe:

• severe headache
• muscle and joint pain or stiffness - avoid strenuous exercise
• temporary hair loss
• severe diarrhoea
• nausea and vomiting
  
• dark urine or light-coloured stools, loss of appetite, stomach pain, yellowing of your eyes or skin
  
• dizziness
  
• blurred vision or changes in your vision (rare)
  
• mood changes including depression (rare)
  

Your doctor will also perform blood tests (cholesterol/triglycerides and liver function test) before you start the treatment and at least once during the course of treatment. This is to monitor for any abnormalities as isotretinoin can cause the level of cholesterol and triglycerides in your blood to increase and may cayuse raised liver enzymes.

The symptoms of a drug allergy include one or more of the following:

• Swollen face/eyes/lips/tongue
• Difficulty in breathing
• Itchy skin rashes over your whole body

If you experience any of these symptoms, you should stop your medication and see your healthcare professional immediately.

​​Inform your healthcare professional if:

• You are allergic to this medication or any of the other ingredients of this medication.
  
• You have diabetes, high cholesterol or triglycerides (fat in the blood), liver or kidney disease.
  
• You are taking any other medications, including supplements, traditional medications and herbal remedies. 
• You are planning to undergo any surgical or dental procedures.
  
• You are planning to undergo any skin or hair removal procedures e.g. waxing, dermabrasions, facial peels, laser treatments. This medication may cause skin to become more fragile, increasing the risk of poor wound healing and scar formation. Avoid these procedures during treatment and for at least 6 months after stopping the medication. 
  
• You are planning to donate blood. Do not donate blood when taking the medication and for at least 1 month after stopping the medication. This is to prevent passing donated blood to a pregnant woman and causing harm to the baby.
