  • Mucous Membrane Irritation: Avoid direct contact of AMELUZ® with the mucous membranes. Wash with water in case of accidental contact.
  • Concomitant use of the following medications may increase the intensity of adverse reactions after light exposure related to photodynamic therapy: St. John’s wort, griseofulvin, thiazide diuretics, sulfonylureas, phenothiazines, sulphonamides, quinolones, and tetracyclines.

Most common adverse reactions were:

  • skin reddening
