About This Medication

What the Medication is Used For

METVIX cream is a prescription cream used with photodynamic therapy (PDT or red light treatment) to treat:

  • skin growths on the face and scalp called actinic keratosis (AK). METVIX cream is only used for AK skin growths that are thin and not dark coloured. AK skin growths are not cancerous.
  • primary superficial basal cell carcinoma (a skin cancer). METVIX cream is NOT used for lesions on the facial H-zone, e.g., ears, nose, upper lip, eyes and temples.

What It Does

The active ingredient in METVIX cream, methyl aminolevulinate is a light sensitive agent. After application of METVIX cream to the skin, it accumulates in the lesions. When the skin lesions are exposed to light (photodynamic therapy), the light causes the drug to react with oxygen, which forms a chemical that kills the precancerous and cancer cells.
