Levaquin (levofloxacin) belongs to the class of drugs called fluoroquinolone antibiotics and can be prescribed to treat a wide range of bacteria-induced infections. Please make sure you report any of the following mild side effects to your health care provider if they do not go away, change in intensity or become bothersome over time: vaginal discharge, insomnia, nausea, diarrhea or constipation, muscle pain, headache, vaginal itching, mild skin, restlessness, dizziness, itching, or nightmares. Otherwise you do not to report them. If you are taking or have recently taken nonsteroidal anti-inflammatory drugs (nabumetone, meloxicam, etodolac, diclofenac, indomethacin, naproxen or ibuprofen), oral steroids (dexamethasone, prednisone, prednisolone, betamethasone or methylprednisolone), insulin or diabetes medication (glyburide), or a blood thinner (warfarin) your health care provider needs to be aware of that. There are other medicines that may interact with Levaquin, so make sure you also mention the ones you are taking but that are not on the list. Keep taking this drug even if you feel a lot better, as improved symptoms do not mean your condition has been treated completely.
