[Routine Help] Spironolactone opinions?

Previously prescribed a high dosage of Doxycycline for roughly one year for initial staph infection and other symptoms. I am no longer staph positive but am still experiencing the same skin issues that first developed almost 2 years ago. Today, I had a follow up with my Dermatologist and he suggested we try Spironolactone (Common brands: CaroSpir, Aldactone) before seeking a referral to see an Infectious Disease specialist.

Has anyone been prescribed this medication??

What are your thoughts/opinions/experiences?

Thanks in advance!
