Before Using This Medicine
In deciding to use a medicine,
the risks of using the medicine must be weighed against the good it will do.
This is a decision you and your doctor will make. For sulfonamide ophthalmic
preparations, the following should be considered:
Allergies - Tell your doctor if you have ever had any unusual or
allergic reaction to any of the sulfa medicines; furosemide (e.g., Lasix)
or thiazide diuretics (water pills); oral antidiabetics (diabetes medicine
you take by mouth); or glaucoma medicine you take by mouth (for example, acetazolamide
[e.g., Diamox], dichlorphenamide [e.g., Daranide], or methazolamide [e.g.,
Neptazane]). Also tell your health care professional if you are allergic to
any other substances, such as preservatives.
Pregnancy - Sulfonamide ophthalmic preparations have not been
shown to cause birth defects or other problems in humans.
Breast-feeding - Sulfonamide ophthalmic preparations have not been
reported to cause problems in nursing babies.
Children - Studies on sulfonamide ophthalmic preparations have
been done only in adult patients, and there is no specific information comparing
use in children with use in other age groups.
Older 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 or if they cause different side effects
or problems in older people. There is no specific information comparing use
of sulfonamides in the elderly with use in other age groups.
Other medicines - 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. When you are taking
sulfonamide ophthalmic preparations, it is especially important that your
health care professional know if you are using any of the following:
Silver preparations, such as silver nitrate or mild silver protein
for the eye - Sulfonamide ophthalmic preparations should not be used with
silver ophthalmic preparations, since a chemical reaction may occur.
