Was prescribed this antibiotic at the er for an ear infection. Had been taking for five days with no feeling of relief from the pressure and pain. on the fifth day I noticed I was shaking and shivering but sweating at the same time. My ears and nose became very clogged, my eyes turned bloodshot and felt a lot of pressure. I was very dizzy, had a very dry mouth was drinking lots of water and urinating a lot. Began to have a panic attack because the symptoms I was experiencing, after about five hours of this I started to feel a bit better. I did not relate this to the drug at first but after I took my second dosage that day I began to feel the same symptoms intensify, only my throat began to swell and I had trouble swallowing. I immediately took two benadryl as I realized I was having a serious allergic reaction. Went to the doctor the next day and was prescribed a different antibiotic, so eight days later I am finally feeling better! Will never take this drug again!
