Kfusi Uses, Dosage, Side Effects, Food Interaction and all others data.

Fusidic acid is an antimicrobial agent that inhibits bacterial protein synthesis. Fusidic acid interferes with amino acid transfer from aminoacyl-tRNA to protein on the ribosomes. Fusidic acid is active against a wide range of gram-positive organisms. The sustained release formulation ensures prolonged contact with the conjunctival sac. Fusidic acid penetrates well into the aqueous humor.

Fusidic acid is a bacteriostatic antibiotic and helps prevent bacterial growth while the immune system clears the infection.

How Kfusi works

Fusidic acid works by interfering with bacterial protein synthesis, specifically by preventing the translocation of the elongation factor G (EF-G) from the ribosome. It also can inhibit chloramphenicol acetyltransferase enzymes.


Kfusi dosage

Adults and children (≥ 2 years): Instill one drop in the affected eye(s) twice daily for 7 days. Treatment should be continued for at least 48 hours after the eye returns to normal.

Side Effects

Fusidic acid is generally associated with very few adverse effects. The most frequently reported treatment-related side-effect is slight stinging or irritation.


  • For ophthalmic use only
  • To avoid possible contamination of the drops, do not touch the tube nozzle or to any surface
  • Do not wear contact lenses during the treatment

Food Interaction

Elimination Route

Sodium fusidic acid tablets have a 91% oral bioavailability. Absorption of the film-coated tablets is complete when compared to a solution, however oral absorption is variable. Oral fusidic acid hemihydrate (suspension) achieved a 22.5% bioavailability in pediatric patients following a 20 milligram/kilogram dose.

Half Life
