Isotretinoin: is there any arrhythmic effect?

Area of Science:

• Dermatology
• Cardiology

Background:

• Oral isotretinoin is a highly effective acne treatment.
• Concerns exist regarding potential adverse effects, including cardiac issues.

Purpose of the Study:

• To investigate the cardiac effects of oral isotretinoin in acne patients.
• To assess safety during a 6-month treatment period.

Main Methods:

• Twenty-six acne vulgaris patients received oral isotretinoin (0.8 mg/kg/day) for 6 months.
• 24-hour Holter monitoring was performed pre-treatment and at 3 months.
• Cardiac rhythm and heart rate were analyzed.

Main Results:

• Twenty-two patients completed the study.
• All patients maintained normal sinus rhythm throughout the study.
• No supraventricular tachycardia or atrial arrhythmia was observed.

Conclusions:

• Six months of oral isotretinoin therapy at 0.8 mg/kg/day significantly improved acne.
• The treatment did not induce any cardiac adverse effects in the studied population.
