Gleolan (aminolevulinic acid HCl) is the first and only FDA-approved optical imaging agent for use during fluorescence-guided surgery (FGS) in patients with glioma [World Health Organization suspected Grades III and IV on preoperative imaging] as an adjunct for the visualization of malignant tissue during surgery. Aminolevulinic acid HCl has been used in over 42 countries for over 100,000 patients1.

Patient Safety Information

Gleolan can cause a sunburn-type skin reaction, also referred to as photosensitivity. Do not take any drugs that may worsen this (such as St. John’s wort, griseofulvin, thiazide diuretics, sulfonylureas, phenothiazines, sulphonamides, quinolones, and tetracyclines) and do not put anything on your skin that contains aminolevulinic acid (ALA) for 24 hours before and for 24 hours after receiving Gleolan.

Errors may occur with the use of Gleolan to see tumors. Sometimes brain tumor cells may fluoresce even if they are not cancerous or those that are cancerous may not fluoresce. Also, cancer cells from other tumors or areas of swelling may fluoresce.

Allergic reactions, including serious allergic reactions, to Gleolan have occurred. Your medical team should monitor you for this and should have emergency equipment ready to manage any such reaction if it occurs.
