This medication should be applied by a health care professional who has experience with this product.
This medication is used in 2 steps. In the first step, your doctor or qualified health care professional will apply aminolevulinic acid directly to the actinic keratoses lesions on your face and scalp. You will then go home and return to the doctor's office 14 to 18 hours after the application of the medication. During this time, while your skin is absorbing the medication, you should keep the affected areas dry and out of direct bright light. That means avoiding sunlight, examination lamps, and unshaded light bulbs at close distances. Before going outside in bright sunlight, you should cover up by wearing a wide-brimmed hat.
In the second step, you return to the doctor's office 14 to 18 hours later. Your health care professional will rinse the actinic keratoses lesions with water and then perform light therapy by applying blue light to the areas where the aminolevulinic acid was applied. You will wear protective goggles during the blue light treatment.
Many things can affect the dose of a medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are using the medication without consulting your doctor.
It is important that this medication be used exactly as recommended by your doctor. If you miss an appointment to receive blue light treatment after having applied aminolevulinic acid, you should continue to avoid exposing the affected areas to sunlight or excessive bright light for at least 40 hours. Contact your doctor as soon as possible.
