- Antibiotic, Ophthalmic
Interferes with bacterial growth by inhibiting bacterial folic acid synthesis through competitive antagonism of PABA
Onset of Action
Improvement of conjunctivitis is usually seen within 3 to 6 days
Use: Labeled Indications
Ophthalmic ointment and solution: Treatment of conjunctivitis and other superficial ocular infections due to susceptible microorganisms: Escherichia coli, Staphylococcus aureus, Streptococcus pneumoniae, Streptococcus (viridans group), Haemophilus influenzae, Klebsiella species, and Enterobacter species.
Ophthalmic solution: Treatment of trachoma as an adjunctive to systemic sulfonamide therapy
Limitations of use: Topically applied sulfonamides do not provide adequate coverage against Neisseria species, Serratia marcescens and Pseudomonas aeruginosa. A significant percentage of staphylococcal isolates are also completely resistant to sulfa drugs.
Hypersensitivity to sulfonamides or any component of the formulation.
Documentation of allergenic cross-reactivity for sulfonamides is limited. However, because of similarities in chemical structure and/or pharmacologic actions, the possibility of cross-sensitivity cannot be ruled out with certainty.
Conjunctivitis, other superficial ocular infections: Note: Taper dose by increasing dosage time interval as condition responds; usual duration of treatment: 7 to 10 days:
Ophthalmic solution: Instill 1 to 2 drops every 2 to 3 hours
Ophthalmic ointment: Apply ~1/2-inch ribbon every 3 to 4 hours and at bedtime
Trachoma: Ophthalmic solution: Instill 2 drops every 2 hours; must be used in conjunction with systemic therapy
Refer to adult dosing.
Conjunctivitis, other superficial ocular infections, or trachoma: Infants ≥2 months, Children, and Adolescents: Ophthalmic: Refer to adult dosing.
Ophthalmic: Avoid contact of tube or bottle tip with skin or eye. Instill sulfacetamide into the conjunctival sac.
Solution: Apply finger pressure to lacrimal sac during and for 1 to 2 minutes after instillation of solution to decrease risk of absorption and systemic effects. For the treatment of trachoma, use must be in conjunction with systemic therapy.
Ointment: May be used as an adjunct to the ophthalmic solution.
Solution: Store at 8°C to 25°C (46°F to 77°F); protect from light. Darkened solutions should not be used.
Ointment: Store at 20°C to 25°C (68°F to 77°F).
There are no known significant interactions.
Frequency not defined.
Hypersensitivity: Hypersensitivity reaction
Neuromuscular & skeletal: Systemic lupus erythematosus
Ophthalmic: Burning sensation of eyes, conjunctival hyperemia, conjunctivitis, corneal ulcer, eye irritation, stinging of eyes
Concerns related to adverse effects:
• Blood dyscrasias: Severe reactions (rare fatalities), including agranulocytosis, aplastic anemia, and other blood dyscrasias, have occurred with sulfonamides (regardless of route). Discontinue at the first sign of serious reaction.
• Dermatologic reactions: Severe reactions (rare fatalities), including Stevens-Johnson syndrome and toxic epidermal necrolysis, have occurred with sulfonamides (regardless of route). Discontinue at first sign of rash.
• Hepatic necrosis: Fatalities (rare) associated with fulminant hepatic necrosis have occurred with sulfonamides (regardless of route). Discontinue at first sign of serious reaction.
• Sulfonamide allergy: Chemical similarities are present among sulfonamides, sulfonylureas, carbonic anhydrase inhibitors, thiazides, and loop diuretics (except ethacrynic acid). Use in patients with sulfonamide allergy is specifically contraindicated in product labeling; however, a risk of cross-reaction exists in patients with allergy to any of these compounds; avoid use when previous reaction has been severe.
• Superinfection: Prolonged use may lead to overgrowth of nonsusceptible organisms, including fungi. If superinfection is suspected, institute appropriate alternative therapy.
• Administration: Do not use concurrently with silver preparations.
• Appropriate use: For topical application to the eye only; not for injection. To avoid contamination, do not touch tip of container to any surface.
• Efficacy: May be inactivated by purulent exudates containing PABA.
Response to therapy, hypersensitivity reactions
Pregnancy Risk Factor
Animal reproduction studies have not been conducted. Use of systemic sulfonamides during pregnancy may cause kernicterus in the newborn.
• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
• Patient may experience burning or stinging. Have patient report immediately to prescriber signs of a severe sulfonamide reaction (rash; red, swollen, blistered, or peeling skin; red or irritated eyes; sores in your mouth, throat, nose, or eyes; fever, chills, or sore throat; cough that is new or worse; loss of strength and energy; any bruising or bleeding; or signs of liver problems like dark urine, feeling tired, not hungry, upset stomach or stomach pain, light-colored stools, throwing up, or yellow skin or eyes), vision changes, eye pain, severe eye irritation, or eye discharge (HCAHPS).
• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
