Uses

What is sulfacetamide used for?

Sulfacetamide is part of a class of antibiotics known as sulfonamides. Sulfonamides work by inhibiting bacterial folic acid synthesis which disrupts the growth of bacteria. As a bacteriostatic agent, it does not directly kill bacteria but rather prevents it from replicating and further spreading.

Sulfacetamide is a broad-spectrum antibiotic mainly indicated for:

  • Skin and eye infections
  • Urinary tract infections (UTIs)

How should I take sulfacetamide?

Sulfacetamide is available in the Philippines as an eye drop preparation. Do not take it orally or apply it to skin wounds.

Prior to use, wash your hands properly with warm water and mild soap. Remove the cap of the eye drop bottle without touching the nozzle. Tilt your head back and gently pull your lower eyelid away from your eye. Instill the appropriate number of drops into the eyelid pouch.

Close your eyes while placing pressure on the inner corner of your eye for one to two minutes. Wipe away any excess medication with a tissue. Repeat in the other eye, if necessary. Wash your hands afterward and avoid touching your eyes and eye area.
