50 mg spironolactone (for hormonal acne) caused diffuse hair loss for me for last 5 months. thyroid/iron/autoimmune/etc. labs all normal. will this resolve without stopping the med? how long could it take? would a change in dosage maybe help?

Hair loss: Spironolactone, being antiandrogenic, actually is used to treat female pattern hair loss. Your hair loss may be genetically determined. Any other female relatives with hair thinning pattern? For further evaluation a dermatologist may be able to pinpoint the type of hair loss you have and determine whether hair regrowth may be likely.

Is that so?: I suspect telogen effluvium, cannot rule out medication effect. I am very surprised that you are still in this medicine when there are alternatives.
