Reduced menstrual flow

2026-08-17 13:24:23
Hello Doctor, I am a 26-year-old female. I have been experiencing very light/less blood flow during my periods recently. I am currently taking isotretinoin for my acne. Could the reduced menstrual flow be a side effect of isotretinoin, or could there be another underlying cause? Please advise if I need any evaluation or tests. Thank you.

A clear cause-and-effect between isotretinoin and lighter periods is not established in the evidence, though a few users do report cycle changes. More commonly, lighter flow reflects stress, weight change, thyroid shifts or hormonal fluctuation. A basic hormone and thyroid check clarifies the picture.
Next Steps
Please book a gynaecology consult with your last three cycle dates and flow pattern; basic blood work will guide from there.
Health Tips
Do not stop your acne treatment on your own before that review.

It can be a side effect of isotretinoin but if it persists we may need to investigate it

Isotretinoin may alter blood flow.
