I was prescribed Levaquin for a sinus infection. Shortly after taking the drug, I noticed a heavy metallic taste in my mouth. After two doses, I did notice the sinus infection was getting much better and decided I was well enough to go out to dinner with my husband (who prescribed the Levaquin). We arrived at the restaurant and within seconds of being seated at our table, I felt an explosion in my head. The pain, slamming through the whole left side of my head, was beating along with my heart! I have never felt head pain such as this. Thank God my husband is a doctor and I quietly told him there was no way I was going to make it through the dinner because my head was EXPLODING! In a our state of fear and embarrassment, he took me home and put me in a hot shower, gave me Advil, steroids, Ativan and Vicodin. I'd never had that many drugs on board in my life! The pain receded from about a level 9 to a 3 within two hours, then completely disappeared after 5 hours. I woke up fine this morning and my husband and I decided Levaquin probably is not a good drug for me, though it does help many other people.
