Is levofloxacin effective for pneumonia? Does it have a lot of side effects?

As with any medication, side effects can occur when using levofloxacin.

However, please remember that this is a prescription medicine and it is up to the doctor to decide whether the therapeutic benefits outweigh the risk of side effects. Pneumonia requires stronger medications than those available over the counter.
Levofloxacin is a frequently used antibiotic. The indication for its use is m.in pneumonia. Side effects that occur with high frequency in patients using this medicine are limited to headaches, dizziness and insomnia.
