Tell your prescriber or health care professional about all other medicines you are taking, including non-prescription medicines, nutritional supplements, or herbal products. Also tell your prescriber or health care professional if you are a frequent user of drinks with caffeine or alcohol, if you smoke, or if you use illegal drugs. These may affect the way your medicine works. Check with your health care professional before stopping or starting any of your medicines.

What should I watch for while taking grepafloxacin?

Tell your prescriber or health care professional if your symptoms do not improve in 2 to 3 days. If you get an unusual reaction stop taking grepafloxacin and call your prescriber or health care professional for advice.

If you are a diabetic, monitor your blood glucose carefully while on this medicine.

You may get drowsy or dizzy. Do not drive, use machinery, or do anything that needs mental alertness until you know how grepafloxacin 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 grepafloxacin 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 grepafloxacin, or at least 2 to 4 hours before your next dose.

Calcium, iron, and zinc preparations can also stop grepafloxacin 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 grepafloxacin. Avoid having dairy products, such as yogurt, milk, or cheese with your medicine; they can reduce the effect of grepafloxacin.

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 are going to have surgery, tell your prescriber or health care professional that you are taking grepafloxacin.
