Delayed periods after taking Isotretinoin

[Omni]

Hello, my period never gets delayed I always get in on time or 2-3 days before but last month I got delayed by 7 days even this month, I still didn't get it. It’s been a week is a delay in periods a side effect of isotretinoin??Can Isotretinoin cause a delay in periods?

@omni Hello, yes according to studies it was reported that 20% of the 40 patients who received oral isotretinoin treatment for at least four months at a dose range of 0.7-1.2 mg/kg/day developed menstrual irregularity; however, the menstrual cycle of all cases returned to normal after the treatment was discontinued. Please talk to your doctor. Thanks!
