Norfloxacin is an antibiotic. The ophthalmic preparation is used to treat infections of the eye.
Norfloxacin is available only with your doctor's prescription.
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For norfloxacin, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to norfloxacin or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Use is not recommended in infants and children up to 1 year of age. Norfloxacin taken by mouth has been shown to cause bone problems in young animals. It is not known whether ophthalmic norfloxacin can cause bone problems in infants. In children 1 year of age and older, norfloxacin is not expected to cause different side effects or problems than it does in adults.
Many medicines have not been studied specifically in older people. Therefore, it may not be known whether they work exactly the same way they do in younger adults. Although there is no specific information comparing use of ophthalmic norfloxacin in the elderly with use in other age groups, norfloxacin is not expected to cause different side effects or problems in older people than it does in younger adults.
Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. Tell your healthcare professional if you are taking any other prescription or nonprescription (over-the-counter [OTC]) medicine.
Certain medicines should not be used at or around the time of eating food or eating certain types of food since interactions may occur. Using alcohol or tobacco with certain medicines may also cause interactions to occur. Discuss with your healthcare professional the use of your medicine with food, alcohol, or tobacco.
The dose of norfloxacin will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of norfloxacin. If your dose is different, do not change it unless your doctor tells you to do so.
The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.
To help clear up your infection completely, keep using norfloxacin for the full time of treatment, even if your symptoms begin to clear up after a few days. If you stop using norfloxacin too soon, your symptoms may return. Do not miss any doses.
If you miss a dose of norfloxacin, apply it as soon as possible. However, if it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule.
Store the medicine in a closed container at room temperature, away from heat, moisture, and direct light. Keep from freezing.
Keep out of the reach of children.
Do not keep outdated medicine or medicine no longer needed.
If your symptoms do not improve within a few days, or if they become worse, check with your doctor.
norfloxacin may cause your eyes to become more sensitive to light than they are normally. Wearing sunglasses and avoiding too much exposure to bright light may help lessen the discomfort.
