Avoided
Isotretinoin and alcohol both stress the liver, creating a potentially dangerous combination:
• Both substances require liver metabolism, increasing strain

• May worsen triglyceride elevation, risking pancreatitis
• Alcohol exacerbates medication dehydration effects
• Increased risk of mental health side effects
