Oravig (Miconazole) – Buccal Mucosa

What Is Oravig?

Oravig (miconazole) is a localized treatment option for fungal infections of the oropharynx (mouth) caused by Candida albicans. It contains the active drug miconazole, which belongs to the class of drugs called imidazoles.

Miconazole works by blocking the release of certain enzymes to stop the formation of an essential component of the fungal cell membrane. It also increases the amount of reactive oxygen species within the cell.

Oravig is a prescription medicine available in the form of buccal tablets to be used locally.

  • Stick the round side of the tablet to the cheek, inside the lip on the gum above the incisor tooth.
  • Hold it in place for 30 seconds with a slight pressure of the finger over the upper lip to make the tablet stick to the gum properly.
  • Apply subsequent doses to alternate sides of the gum.
  • The tablets should dissolve slowly in the mouth by absorbing moisture.
  • If the buccal tablet does not stick to the application site or falls off within the first six hours, reposition the same tablet immediately. 
  • If the tablet does not adhere, use a new tablet.

Avoid situations that interfere with the sticking of the tablet, including:

  • Touching or pressing the tablet after placement
  • Wearing an upper denture 
  • Chewing gum
  • Hitting tablet when brushing teeth
  • Rinsing mouth too vigorously

Your local pharmacist can be a great resource if you have questions about the best way to throw away your medications.

Candida is a fungal infection in the mouth and is associated with underlying issues such as immunosuppression, diabetes, taking broad-spectrum antibiotics, and corticosteroid drug use. In most people, untreated candidiasis persists for months or years unless associated risk factors are treated or eliminated.

Fungal infections generally take a long time to get rid of. Use your prescribed medication regularly to get maximum therapeutic benefits. Take care of your oral health to prevent bacterial and fungal infections from developing in the first place. Good oral hygiene, which includes regularly brushing your teeth, and avoiding smoking tobacco can lower your risk.
