Common questions about Levulan (FAQ)
Q: Is Levulan the name of the drug or the brand name of the treatment?
Levulan Kerastick is the brand name of the prescription product used in the procedure. The active substance in the solution is Aminolevulinic Acid (ALA), which is a precursor compound. Official documents classify ALA as the agent that enables the light-activated photodynamic therapy process.
Q: Is Levulan a type of chemotherapy?
Official regulatory documents classify Levulan as a Photodynamic Therapy (PDT) agent and a topical photochemotherapeutic agent. This means it uses a chemical and light to locally destroy abnormal cells. However, it is a localized, non-systemic treatment and is not considered a traditional systemic chemotherapy.
Q: How is Levulan different from other topical skin treatments?
Levulan is distinguished because it functions as a photosensitizer precursor for a two-stage procedure. Its therapeutic effect relies on a chemical reaction that is activated only when the skin is subsequently exposed to light from a specific device. Most other topical treatments do not require this mandatory light-activation step.
Q: How long does the Levulan treatment session usually last?
The entire treatment is defined by two required phases according to the official administration protocol. The first phase, drug application and incubation, lasts between 3 to 18 hours depending on the treatment area. The second phase, blue light illumination, lasts for a continuous period of 16 minutes and 40 seconds.
Q: What happens if the skin is not exposed to light after Levulan is applied?
The drug is converted into its active photosensitive form by the cells, but its therapeutic action only occurs when it is exposed to the blue light. If the light treatment is missed or delayed, official guidance specifies continued strict avoidance of sunlight and bright indoor light for at least 40 hours after the solution was first applied.
Q: What kind of interactions can Levulan have with my daily moisturizer?
Official instructions advise that the skin must be clean and free of all makeup, moisturizers, and sunscreens before the Levulan solution is applied for incubation. Official resources describe that moisturizers are typically applied to the treated area after the light treatment phase is complete.
Q: Can I use other topical medications with Levulan?
The official labeling documents a risk of additive phototoxicity when used with other photosensitizing topical or systemic medications. Official resources indicate that resuming prescribed or anti-aging topical products is often suggested only after the skin has healed, with some sources mentioning at least a one-week wait.
Q: Are the results from Levulan permanent?
Official research studies track the effectiveness by measuring the initial clearance rate of lesions. These studies also follow the recurrence rate of cleared lesions for up to one year after treatment. Regulatory documents do not use the term 'permanent' when describing the durability of the response.
Q: Why is blue light often used instead of other colors of light with Levulan?
The mechanism of action requires the activation of the photosensitive compound Protoporphyrin IX (PpIX) that accumulates in the target cells. Blue light is specified in the official protocol because its wavelength is effective at activating this specific photosensitizer to initiate the therapeutic destruction of the targeted cells.
Q: Is Levulan treatment considered cosmetic or medical?
Levulan Kerastick is regulated as a prescription medicine with a specific medical purpose. It is FDA-approved for the treatment of actinic keratoses (AKs), which are precancerous skin lesions caused by sun damage. The treatment is therefore classified as a medical intervention.
Q: Can I drive home after receiving Levulan photodynamic therapy?
The official labeling includes a warning for a rare but serious side effect known as a transient amnestic episode (temporary memory problem) following blue light exposure. Due to this potential side effect, and the need to follow light avoidance protocols, caution is advised regarding driving or operating machinery immediately after the procedure.
--UNSAFE: Driving/Caution Statement
Q: Is the photodynamic therapy procedure with Levulan painful?
According to patient information and clinical trial data, most patients will experience local sensations during the blue light illumination phase. These sensations include tingling, stinging, prickling, or burning of the treated skin, which are typically temporary and improve once the light treatment is finished.
Q: Can Levulan cause scarring?
The official safety profile for the drug, which lists common and rare adverse reactions, does not list scarring as a reported side effect of the treatment. Some patient-focused resources describe the treatment as one that is associated with low risk of scarring.
Q: How many treatments are typically needed?
The treatment is limited to one application and illumination session per region within an 8-week period. While retreatment is permitted if lesions have not fully resolved after 8 weeks, clinical data suggests that many patients are assessed for lesion clearance following 1 to 2 in-office treatments.
Q: Does Levulan treatment hurt more on certain parts of the body?
Clinical data collected during trials indicate that the frequency and intensity of some common local adverse reactions, such as stinging or burning, may be different across various treatment sites. The most commonly treated areas are the face, scalp, and upper extremities.
Q: Can Levulan be used on mucous membranes?
Official regulatory documents strictly approve the medication for Topical Use Only on the skin lesions of the face, scalp, and upper extremities. It is not approved for use on mucous membranes, the eyes, or other non-cutaneous areas.
Q: What should I do if my skin has a severe reaction after Levulan?
In the event of a severe or unusual reaction, such as a temporary memory problem or severe skin changes, official patient instructions state that the appropriate step is to immediately contact a healthcare provider. They also advise reporting side effects to the regulatory agencies, such as the FDA.
Q: Can Levulan be used to treat sun damage?
Levulan is officially approved for the treatment of actinic keratoses (AKs). These lesions are defined as rough, scaly patches on the skin that are a direct result of chronic sun exposure.
Q: Can I wear makeup immediately after the Levulan treatment?
Patient resources advise that it may be possible to apply makeup after the treatment, but only if there are no open areas or breaks in the skin. Official patient resources indicate that makeup is typically applied after the treatment, provided there are no open areas or breaks in the skin.
Q: How soon after the procedure can I return to work or school?
Due to the need for strict light avoidance for 40 hours after the drug application, patients are typically advised to stay indoors during this period. Patients are often advised they may be able to resume work or school activities within 24 to 48 hours after the photodynamic therapy is completed.
Q: What happens if I forget to wash off the Levulan after the application time?
The solution is designed to be absorbed into the target cells during the incubation period. Patient instructions state that the treated area should be gently rinsed and patted dry just before the blue light treatment. Official instructions indicate that the face should not be washed between the application and the light treatment steps.
Q: Is the light source used in the procedure dangerous?
The light device (BLU-U) is described in regulatory documents as a low intensity blue light device that is designed to provide only the fixed, required amount of light to activate the solution. Protective eyewear is provided and must be worn during the treatment to ensure safety.
Q: Has Levulan been studied in people with darker skin tones?
Official regulatory documents include a warning that patients with darker skin that tends to turn brown or discolor with exposure to light or laser treatments may not be suitable candidates for the treatment. The evidence base is not fully documented across all skin phototypes.
Q: Is Levulan the only aminolevulinate drug approved for skin conditions?
Levulan's active ingredient is Aminolevulinic Acid (ALA) and is one of the topical photochemotherapeutic agents approved for actinic keratoses. Related regulatory documents mention other ALA-based products used in similar Photodynamic Therapy protocols.
Q: Is Levulan used only by dermatologists?
The official prescribing information states that the product is a prescription medicine that must be applied in a doctor's office and used by a qualified healthcare provider only. It does not restrict the procedure exclusively to dermatologists.
Q: Is the redness after the procedure a sign that the treatment is working?
Redness (erythema) and swelling are officially described as expected, very common adverse reactions of the treatment. Clinical data indicates the intensity of this local reaction is often related to the level of underlying sun damage in the treated skin.
