Do I need to change my diet if I am taking 2 (and working up to 3) 25mg dose/day of spironolactone for acne?

I am starting spironolactone for acne along with antibiotics. I read there is a risk for hyperkalemia and was wondering if I need to change my diet and only eat low potassium foods? I eat a lot of vegetables currently and those tend to have high K. I also already have low blood pressure, what can I do to prevent from getting even more dizzy on the medication? Thank you
