@fdixon63, I've been taking Spironolactone 25 mg along with Hydrochlorothiazide 25 mg for quite a few years for blood pressure and hypertension but never had a side effect like your husband but it's good to hear he has an appointment with a dermatologist to check it out. Here's some information from Mayo Clinic on Spironolactone side effects if you haven't already done any research - https://www.mayoclinic.org/drugs-supplements/spironolactone-oral-route/description/drg-20071534.

Is your husband taking the drug for high blood pressure or hypertension? Have you discussed the side effects with his doctor?
