Task: Answer Verification
Input (English): Question: Does isotretinoin prolong QT intervals and QT dispersion in patients with severe acne : a surprising finding for a drug with numerous side effects?
Answer: In patients with severe acne, six months of 0.8 mg/kg/day of isotretinoin therapy neither prolongs QT interval, nor increases QT dispersion. This effect is not related to blood lipids, homocysteine or lipoprotein (a) levels. Our findings indicate that from the point of polymorphic ventricular tachycardia risk, 0.8 mg/kg/day of isotretinoin therapy is a safe choice in acne treatment.
Output (English): no
