I was just prescribed Levaquin for a sinus infection/bronchitis. I am a healthy 36 year old who is not currently taking any medications. I got the Leva-pac, 5 days, 750 mg. each. The first night I slept fitfully, but was still feeling the infection, so blamed it on that. The second night, however, was HORRIBLE. Although my sinus symptoms were markedly better, I literally thought I was going to have a heart attack during the night. I had severe insomnia...only slept 20 minutes total from 9 p.m. to 7 a.m., and in those 20 minutes I had a horrible nightmare/panic attack, jaring me awake with clenched teeth, profuse sweating and feeling as though I was choking. I was overly anxious, paranoid and had severe leg cramps. My heart was racing and I would alternate between being overly hot and then overly cold in a matter of minutes. It was an experience I never want to have again. My husband insisted I stop the antibiotic even though that is what you should never do with an antibiotic. Even though I have been off two days now, I am still feeling some of the effects, especially at night.
