Re: Does Spironolactone cause some breast tenderness??
Yes, that is listed under one of the side effects. My little drug book says: common side effects: nausea,vomiting,appetite loss, stomach cramps,diarrhea, Infrequent:dizziness,muscle cramps, headache,sensitive skin, dry mouth,decreased sex drive,tender breast,deepening voice,hair growth,incresed sweating. Both of these catagories say to contunue and call doctor when convenint. Rare side effect that you should discontinue are: black,tarry,bloody stool, bloody urine,fever,joint pain, rash, yellow skin,irregular heart beat, unusual tiredness, weakness, mood changes, red burning tougue. I would still let you doctor know about this.
