From the Guidelines
Sulfacetamide ophthalmic solution is used to treat bacterial eye infections such as conjunctivitis, blepharitis, and corneal ulcers, and its use is associated with earlier clinical and microbiological remission compared to placebo in mild bacterial conjunctivitis 1.
Key Points to Consider
- The choice of antibiotic is usually empiric, and there is no clinical evidence suggesting the superiority of any particular antibiotic, including Sulfacetamide, in treating mild bacterial conjunctivitis 1.
- A 5- to 7-day course of a broad-spectrum topical antibiotic, such as Sulfacetamide, is usually effective in treating bacterial conjunctivitis 1.
- Patients should be instructed to use the medication as directed, typically 1-2 drops in the affected eye(s) every 2-3 hours while awake for the first few days, then reducing to 1-2 drops 4 times daily until the infection resolves.
- It is essential to continue the full course of treatment, even if symptoms improve earlier, to prevent recurrence.
- Patients should be advised to wash their hands thoroughly, avoid touching the dropper tip to any surface, including the eye, and follow proper application techniques to minimize the risk of contamination and side effects.
- Temporary stinging or burning may occur upon application, and patients should contact their doctor if symptoms worsen or don't improve within 2-3 days, or if they experience severe irritation, swelling, or allergic reactions.
Important Considerations
- The use of topical antibacterial therapy, including Sulfacetamide, may reduce transmissibility and allow for an earlier return to school for children with mild bacterial conjunctivitis 1.
- Povidone-iodine 1.25% ophthalmic solution may be as effective as topical antibiotic therapy for treating bacterial conjunctivitis and could be considered when access to antibiotics is limited 1.
- The economic impact of conjunctivitis is considerable, and the ophthalmologist plays a critical role in breaking the chain of transmission of epidemic adenoviral conjunctivitis by educating patients and families about proper hygiene 1.

From the Research
Use of Sulfacetamide Ophthalmic Solution
- Sulfacetamide ophthalmic solution is used to treat bacterial conjunctivitis, as shown in studies 3, 4, 5.
- It is effective against certain bacteria, including Haemophilus influenzae and Streptococcus pneumoniae 3.
- However, it may not be as effective against Chlamydia trachomatis, as shown in a study where topical sulfacetamide therapy resulted in persistent conjunctival infection and nasopharyngeal colonization in some infants 6.
- Sulfacetamide ophthalmic preparations are commonly used to treat bacterial conjunctivitis in children, especially in the newborn period 4.
- The solution can be used in combination with other antibiotics, such as trimethoprim and polymyxin B, to treat ocular surface infections 5.
Efficacy and Safety
- Studies have shown that sulfacetamide ophthalmic solution is generally safe and effective in treating bacterial conjunctivitis 3, 4, 5.
- However, the efficacy of sulfacetamide may vary depending on the specific bacterial infection being treated, as shown in the study on Chlamydia trachomatis 6.
- The combination of sulfacetamide with other antibiotics, such as trimethoprim and polymyxin B, may provide effective treatment for ocular surface infections 5.
Comparison with Other Treatments
- Sulfacetamide ophthalmic solution has been compared to other treatments, such as oral erythromycin, in the treatment of Chlamydia trachomatis conjunctivitis 6.
- It has also been compared to other topical antibiotic solutions, such as trimethoprim-polymyxin B, in the treatment of bacterial conjunctivitis 3, 5.
