Difficulty Concentrating When Taking Propecia

I have been on Propecia for just over 2 weeks. This second week, I have experienced notable fatigue and a cloudy head with a lowered ability to concentrate. My lifestyle has stayed the same; if anything I’ve been getting more sleep than normal.

Have you heard of this type of side effect? Is it something that might go away as my body adjusts? Should I decrease my dosage from 1mg to .5mg?

Thanks for any advice you can provide.

I have not heard your type of complaint before from any of my patients. I would wonder if you have been too focused in looking for changes on this drug. If you look hard, you can make these changes occur on a psychological etiology. If you were my patient, I would advise you to ‘stay the course’.
