Tell your doctor if you have or have had:

• allergies to drugs

• an unusual reaction to other sulfa drugs, furosemide, thiazide diuretics (water pills), sulfonylurea (diabetes drugs), or carbonic anhydrase inhibitors

Tell your doctor about any other drugs you take, including aspirin, herbs, vitamins, and other nonprescription products.

• Call your doctor if your symptoms do not improve in a few days.
• You may get blurred vision or stinging or burning after application.
• Use all the sulfacetamide your doctor prescribed, even if you feel better before you finish. If you stop too soon, your symptoms could come back.

• Follow directions for application of eye drops and ointments.
• Do not let the tip of the applicator touch your eye, your fingers, or anything else. It could become contaminated.
• If the drug gets dark brown, throw it away.
• If you miss a dose, take it as soon as you remember, but skip it if it is almost time for the next dose. Do not take double doses.
• Do not share your medication with others.
• Take the drug at the same time(s) each day.
• Store at room temperature with lid on tightly. Do not store in the bathroom. Do not expose to heat, moisture, or strong light. Keep out of reach of children.

Evaluations of Drug Interactions 2003 lists no drugs, biologics (e.g., vaccines, therapeutic antibodies), or foods as causing “highly clinically significant” or “clinically significant” interactions when used together with the drugs in this section. We also found no interactions in the drugs’ FDA-approved professional package inserts. However, as the number of new drugs approved for marketing increases and as more experience is gained with these drugs over time, new interactions may be discovered.

Call your doctor immediately if you experience:

• itching, redness, or swelling not present before using this drug
• other adverse effects like those that occur with the sulfonamides (sulfa drugs). See sulfisoxazole (GANTRISIN), for examples.
