I took allegra for allergies. Whenever I take it I get a fungus taste in my mouth. I went to the dr for my cough was diagnosed with sinitis and was told the cough and wheezing was from agitation from drainage. I am almost done with the medicine. My cough hasn't went away and I keep coughing up stuff that taste like mold. My resting heart rate is btw 96-110 at all times and I am shaky and nauseous. ..
