If you are a diabetic monitor your blood glucose carefully. If you get an unusual reaction stop taking levofloxacin and call your prescriber or health care professional for advice.
You may get drowsy or dizzy. Do not drive, use machinery, or do anything that needs mental alertness until you know how levofloxacin affects you. To reduce the risk of dizzy or fainting spells, do not sit or stand up quickly, especially if you are an older patient.
Drink several glasses of water a day. Cut down on drinks that contain caffeine.
Antacids can stop levofloxacin from working. If you get an upset stomach and want to take an antacid, make sure it has been at least 2 hours since you last took levofloxacin, or at least 2 to 4 hours before your next dose.
Calcium, iron, and zinc preparations can also stop levofloxacin from working properly. Take calcium tablets, iron tablets, zinc tablets, or vitamins that contain calcium, iron, or zinc at least 2 hours before or two hours after levofloxacin.
Keep out of the sun, or wear protective clothing outdoors and use a sunscreen. Do not use sun lamps or sun tanning beds or booths.
If you notice symptoms such as pain, burning, tingling, numbness and/or weakness, stop taking levofloxacin and contact your healthcare provider immediately.
If you notice pain or swelling of a tendon or around a joint, stop taking levofloxacin. Call your healthcare provider. Rest the affected area. Do not exercise or take levofloxacin until your healthcare provider tells you to do so.
