Updated: 

Levulan Kerastick is a prescription medication used to treat to actinic keratoses of the face or scalp. This is a condition of small crusty or scaly bumps or horns on or under the skin that result from exposure to sunlight and can develop into skin cancer. Levulan Kerastick belongs to a group of drugs called photosensitizing agents. When activated by light, Levulan Kerastick damages the cells of lesions and bumps.

This medication comes in a topical solution form and applied to the affected skin area by a doctor. You must return to the doctor 14 to 18 hours after application to be treated by blue light PDT (photodynamic therapy).

Common side effects include blistering, itching, and bleeding of skin at site of application. During PDT (lasts for approximately 17 minutes), you may experience sensations of tingling, stinging, prickling or burning of the treated lesions. These feelings of discomfort should improve at the end of the light treatment.

Levulan Kerastick Precautions

Serious side effects have been reported with Levulan Kerastick.

  • During the time period between the application and exposure to blue light PDT, the treatment site will become sensitive to light (photosensitive).
    • You should avoid exposure of the photosensitive treatment sites to sunlight or bright indoor light (examination lamps, operating room lamps, tanning beds, or lights at close proximity) during the period prior to blue light treatment.
    • Exposure may result in a stinging and/or burning sensation and may cause erythema and/or edema of the lesions. Protect treated lesions from the sun by wearing a wide-brimmed hat or similar head covering of light-opaque material. Sunscreens will not protect against reactions caused by visible light. It has not been determined if perspiration can spread Levulan Kerastick outside the treatment site to the eyes or surrounding skin.
  • Application to areas around lesions of damaged skin (perilesional) may result in photosensitization. Upon exposure to light from the blue light PDT, you may experience a stinging and/or burning sensation and may become red and/or may swell in a manner similar to that of actinic keratoses.
  • Because of the potential for skin to become photosensitized, this medication should be used by a health professional.

Do not use this medication if

  • are allergic to Levulan Kerastick
  • you are photosensitive at wavelengths of 400-450 nm
  • have a history of porphyria
  • have allergies to porphyrins
  • are sensitive to any of the components of this medication

Inform MD

Before using Levulan Kerastick,

  • tell your doctor and pharmacist if you are allergic to Levulan Kerastick, porphyrins, or any other medications
  • tell your doctor and pharmacist what prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking or plan to take
  • tell your doctor if you have porphyria (a condition that causes sensitivity to light). Your doctor will probably tell you not to use Levulan Kerastick.
  • tell your doctor if you have or have ever had any other medical conditions
  • tell your doctor if you are pregnant, plan to become pregnant, or are breastfeeding. If you become pregnant during treatment with Levulan Kerastick, call your doctor.
  • if you are having surgery, including dental surgery, tell the doctor or dentist that you are using Levulan Kerastick.
  • you should know that Levulan Kerastick will make your skin very sensitive to sunlight (likely to get sunburn). Avoid exposure of treated skin to direct sunlight or bright indoor light (e.g. tanning salons, bright halogen lighting, close task lighting, and high power lighting used in operating rooms or dental offices) before exposure to blue light treatment. Before going outdoors in the sunlight, protect treated skin from the sun by wearing a wide-brimmed hat or other head covering that will shade the treated area or block the sun. Sunscreen will not protect you from sensitivity to sunlight. If you feel burning or stinging of the treated areas or see that they have become red or swollen, be sure that you are keeping the area protected from sunlight or bright light.
