I have had a chronic dry cough for the past 5 years. Now they are saying I have whooping cough. I have been taking Clarithromyn ER TB 500 mg. the generic for Biaxin XL 500 mg. Last night I had to go to the ER. I felt like I was having a heart attack. I could not catch my breath, my left arm was tingling, kind of going numb. Also felt like I might pass out. On the way to the ER I was trembling, and very jittery. I felt very STRANGE!!!!!! The ER said it was just a panic attack. I have never had panic attacks!!! The past few day I have been telling my co-workers how I felt like my throat was closing up. I am calling the doctor today to see about not finishing my last 4 days of the medicine. I am glad I found this site to see that other people have experienced the same symptoms and I am not going crazy.
