Took my 3rd dose of the Avelox samples my Dr. gave me for a sinus infection. Yesterday I thought it might have been the infection getting worse before it got better and the nausea was from the nasal drainage. Given Clarinix D which I thought might have been causing the dizzy, shaky feeling. Today I woke up feeling pretty good, but took the Avelox with a bagel and I felt very sick to my stomach, hot and flushed, dizzy, throbbing head and wanting to cry. I didn't take the decongestant so I know it was the Avelox. I have RA and yesterday it felt like all my joints were throbbing and I was having a flare up. My doctor's office was closed today, I won't take this again tomorrow. I'll wait until Monday to get a different antibiotic.
