No. Levofloxacin is a very powerful antibiotic in the same class as "cipro" it is used for treating severe pneumonias and uti/kidney infections. In general, when a doctor recommends it, they mean business. All good medications will have some side effects and a doctor will weigh the risks of those effects against the good the medicine will do. If someone thought Levaquin (levofloxacin) was needed, take it!
No. In the general population Levaquin (levofloxacin) is a very safe drug. It can cause side effects such as confusion and dizziness in the elderly and can rarely affect your Achilles tendon (causing pain or rupture). These are all rather rare and the drug has been around for greater than a decade.
