A rare serious side effect is liver toxicity, and for this reason, liver function tests are required if treatment with Fluconazole or Diflucan is long term.
Exfoliative skin disorders can occur.

People with AIDS are more susceptible to side effects. Because Fluconazole or Diflucan can cause liver toxicity, people with liver problems must be careful.
