Doctor prescribed a "microdose", what do you think?

Hi, I am not well-versed with GLP-1s but I have PCOS and take metformin for it. They also prescribed me Spironolactone a while ago but my side effects were too much to bear.

So my primary suggested I try Wegovy pill, 1.5mg/day for PCOS symptoms (weight gain, inflammation, irregular menses). She said we can stay at this dose instead of going up to the next level of 4mg.

Would love to know your thoughts. Is this a microdose? Thanks sm
