Generic Name: aminolevulinic acid (a-mee-no-LEV-U-lin-ik)
Brand Name: Levulan Kerastick

How to use aminolevulinic acid solution:
Use aminolevulinic acid solution as directed by your doctor. Check the label on the medicine for exact dosing instructions.
- Aminolevulinic acid solution will be applied by a qualified health care provider.
- This is a two-part procedure. You will receive a blue light treatment the day after aminolevulinic acid solution is applied.
- Once aminolevulinic acid solution is applied, do not wash the treated lesions. Keep the lesions dry and avoid exposure of treated areas to sunlight and bright indoor light. You should return to your health care provider the next day to receive the blue light treatment. This is the second and final treatment step.
- Before receiving the blue light treatment, aminolevulinic acid solution will be rinsed off of your skin with tap water, and you will be given goggles to protect your eyes. The blue light will not heat your skin.
- During the blue light treatment, you will experience tingling, stinging, prickling, or burning of the treated area. These effects stop at the end of treatment, which lasts for about 17 minutes.
- After the blue light treatment, the treated area and surrounding skin will redden, and swelling or scaling may also occur. This is temporary and should completely resolve 4 weeks after this treatment.
- Do not directly cover the treated area(s) unless advised to do so by your health care provider. Excessive irritation may occur.
- If for any reason you cannot return to your health care provider within 14 to 18 hours after aminolevulinic acid solution is applied, call your health care provider. Continue to avoid bright light for at least 40 hours.
- If you miss a dose of aminolevulinic acid solution, contact your doctor right away.
Ask your health care provider any questions you may have about how to use aminolevulinic acid solution.

Stinging, burning, flushing, and swelling may occur if the lesions are exposed to bright light.
- If you feel stinging or burning on the treated skin lesions, further reduce your exposure to light.
