Dr gave me aldactone (spironolactone) for acne, it worked but I feel extremely tired, weak. I do not have hbp. Is this possible should I stop taking it?

Talk to MD&stop. I will discuss with your doctor and than stop aldactone (spironolactone).Aldactone is used for hormonal acne and it can be the cause of your symptoms.It can cause fall in blood pressure and/or high level of pottasium .I will get it checked.
Weak on aldactone (spironolactone) You should speak to your doctor about your problems. He would be the best person to speak to as he would know the most about them. Good luck.
