I have been on Nadolol for several months at 40 mg a day for fast heart rate. Last week my cardiologist upped the dosage bc my heart rate ever-increasing again. Since then , probably the so days after the dosage increase...I have had a host of weird things....swollen ankles...itching skin...insanity itchy...all over my body...and muscle weakness. The nurse says this should not be a reaction since I had been on the med before but all they did was up the dosage...but it all started after thrilled dosage....has anyone else ever had this.???
