Kerydin vs Jublia – Which Is Better For Treating Onychomycosis?


It is the brand name of a generic drug called tavaborole, which belongs to a group of drugs known as antifungals.

The medication works by inhibiting an enzyme known as cytosolic leucyl-transfer RNA synthetase, that plays an essential role in fungal essential protein synthesis. This leads to the death of fungus.

It is produced by Anacor Pharmaceuticals, a company focused on developing novel small-molecule therapeutics. The US Food and Drug Administration originally approved this medication in 2014.


This prescription medication is indicated for onychomycosis of the toenail due to Trichophyton mentagrophytes or Trichophyton rubrum. It is the first oxaborole-class topical antifungal that can be used for onychomycosis.

Onychomycosis is a fungal infection that affects either the toenails or fingernails. It is the most common disease of the nails and constitutes about fifty percent of all nail abnormalities. According to statistics, about 10% of the adult population in the United States is affected.


You may have this condition if one or more of your nails are:

  • smelling slightly foul;
  • a dark color, caused by debris building up under the nail;
