Superficial Candida Infections

Candida albicans is the most common cause of fungal infection. It is a normal commensal organism of the skin, gastrointestinal tract and mucous membranes. Therefore, isolation of C.albicans from asymptomatic patients does not necessarily imply the need for treatment.

Caution:

  • Antifungals (azoles especially) can interact with multiple medicines. Contact pharmacy for further advice. 
  • Avoid fluconazole in pregnancy
