What are the uses of this medicine?

• Sulfacetamide Ophthalmic is used for the treatment of conjunctivitis and other superficial ocular infections due to susceptible microorganisms, and as an adjunctive in systemic sulfonamide therapy of trachoma.

Topically applied sulfonamides are considered active against susceptible strains of the following common bacterial eye pathogens: Escherichia coli, Staphylococcus aureus, Streptococcus pneumoniae, Streptococcus (viridans group), Haemophilus influenzae, Klebsiella species, and Enterobacter species.

• Topically applied sulfonamides do not provide adequate coverage against Neisseria species, Serratia marcescens and Pseudomonas aeruginosa.

How does this medicine work?

• The sodium salt form of sulfacetamide, a synthetic sulfanylacetamide derivative with bacteriostatic activity.
• Sulfonamides inhibit bacterial synthesis of dihydrofolic acid by preventing the condensation of the pteridine with aminobenzoic acid through competitive inhibition of the enzyme dihydropteroate synthetase.
• Resistant strains have altered dihydropteroate synthetase with reduced affinity for sulfonamides or produce increased quantities of aminobenzoic acid.

• The effectiveness of sulfonamides may be reduced by the para-aminobenzoic acid present in purulent exudates.
• To avoid contamination, do not touch tip of container to the eye, eyelid or any surface.
• Tell your doctor if you wear soft contact lenses. If the brand of sulfacetamide you are using contains benzalkonium chloride, wait at least 15 minutes after using the medicine to put in soft contact lenses.
