These may affect the way your medicine works. Check with your health care professional before stopping or starting any of your medicines.

Tell your prescriber or health care professional if your symptoms do not improve in 2 to 3 days.

You may get drowsy or dizzy. Do not drive, use machinery, or do anything that needs mental alertness until you know how sparfloxacin 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.

It is important that you stay out of the sun (even during cloudy weather) while taking sparfloxacin and for five days after treatment. You should also avoid sunlight coming through windows. Do not go out in the sun even if you are using a sunscreen. Also, do not use artificial light such as sunlamps. If you must be in the sun for a brief time, make sure you cover as much of your skin as possible with clothing. Stop taking sparfloxacin and contact your physician if you develop a skin rash, burning, redness, swelling, blisters, or itching.

Antacids can stop sparfloxacin from working. If you get an upset stomach and want to take an antacid, make sure there is an interval of at least 4 hours since you last took sparfloxacin.

Iron and zinc preparations can also stop sparfloxacin from working properly. If you are taking mineral supplements or vitamins containing zinc or iron, make sure there is an interval of at least 4 hours since you last took sparfloxacin.
