I was prescribed Biaxin XL 1000mg x7 days for a possible secondary bronchial infection (I have had the flu and am coughing up beige sputum). I took the medicine for the first time last night. I made sure to drink yogurt along with it and took it with food as I was worried about GI effects. Wow! Within 2 hours I had major episodes/waves of severe nausea, stomach gurgling/hunger. I definitely developed a dry mouth and metallic taste. I became lightheaded (this is still going on the next day) and dizzy. I feel spaced out completely. Last but not least I had a really bad nightmare last night. I do not ever have nightmares!!! I am an RN, so I am not a "crazy" patient having psychosomatic symptoms. I am never taking this drug again unless my very life depends on it. I will take my chances and let my body heal naturally. Awful drug.
