After 4 days of Macrobid didn't help my UTI, I was prescribed 750mg of Levaquin per day. On the first day, the doctor had me take a double dose. That night, my left arm was tingling and numb no matter what I did. I woke up suddenly after only an hour of sleep. I tried to stumble to the restroom but could barely stand. My legs were completely weak, my anxiety was through the roof, my heart was pounding and the room was spinning out of control. I couldn't tell if the bedroom was upside down or sideways. After a trip to the ER, they told me I was reacting to the high does of Levaquin but it wasn't an allergic reaction. They gave me a lot of fluids and sent me home and told me to still take the Levaquin since I had to get rid of the UTI. The next day, the UTI was much better. I took a 1/2 dose of Levaquin. I had some side effects (weak all over, anxiety, feeling hot, slightly dizzy) but not terrible. I hate to take this stuff but I know it is working. The half dose seems to be enough.
