I was glad to read this, I thought I was crazy. Been taking Biaxin for 3 days for a bad sinus/throat infection, BP today went up to 130/100, took my blood pressure meds (which I had been able to stop taking several months ago) but it just went up on the top to 150/98. My heart is racing and I'm so tired but can't sleep. Severe metallic taste in my mouth. Skin is burning, temperature is 100 and profuse sweating as mentioned above...I'm calling the Dr. now to get something else. Does anyone know how long it takes to get this out of your system?
