Who should not use aminolevulinic acid (Levulan Kerastick)?
Before using aminolevulinic acid, tell your doctor if you have
- porphyria, or
- a bleeding or blood clotting disorder.
You may not be able to use aminolevulinic acid, or you may require a dosage adjustment or special monitoring during your treatment.
Aminolevulinic acid is the FDA pregnancy category C. This means that it is not known whether aminolevulinic acid will harm an unborn baby. Do not use aminolevulinic acid without first talking to your doctor if you are pregnant.
It is unknown whether aminolevulinic acid passes into breast milk. Do not use aminolevulinic acid without first talking to your doctor if you are breast feeding a baby.
How should I use aminolevulinic acid (Levulan Kerastick)?
Only a qualified doctor or other healthcare professional should apply aminolevulinic acid. Aminolevulinic acid is not intended for application by the patient.
Your doctor or other health care professional will prepare the aminolevulinic acid solution in the applicator. Aminolevulinic acid solution application will be completed within 2 hours of preparation.
Application of aminolevulinic acid involves either scalp or face lesions, but not both at the same time. It will be applied directly to the individual areas and not to the surrounding skin.
After aminolevulinic acid has been applied, wear sunlight-protective clothing such as a wide-brimmed hat or similar head covering. Sunscreens will not protect you. Avoid exposure to sunlight or bright indoor light (examination lamps, operating room lamps, tanning beds, or very close lights). If you experience stinging or burning of the treated skin, reduce your exposure to light. It has not been determined if perspiration can spread aminolevulinic acid outside the treatment site to the eyes or surrounding skin.
Fourteen to eighteen hours after application of aminolevulinic acid, you must return to the doctor's office to receive a special blue light treatment. Prior to the blue light treatment, the lesions will be rinsed with water. You will be given special goggles to wear during the treatment which will last about 17 minutes. The blue light is of low intensity and will not heat the skin. However, you may experience tingling, stinging, prickling, or burning of the treated skin. These feelings of discomfort should improve at the end of the light treatment.
Following the treatment, you will experience some redness, swelling, and scaling of the lesions, and to some degree, the surrounding skin. These changes are temporary and should completely resolve by 4 weeks after treatment. If these side effects are excessive, talk to your doctor.
Aminolevulinic acid and light treatment is usually done once to each area with lesions. The procedure may be repeated after 8 weeks on lesions that have not completely resolved.
Store aminolevulinic acid at room temperature away from moisture and heat.
