Drug information provided by: Merative, Micromedex®

Your doctor will check your progress closely while you are receiving this medicine. This will allow your doctor to see if the medicine is working properly and to decide if you should continue to receive it. Blood tests may be needed to check for unwanted effects.

This medicine can cause episodes of temporary memory loss. Check with your doctor right away if you have problems with your memory, confusion, or disorientation.

For Ameluz® topical gel:

  • If your condition does not improve within 3 months, or if it becomes worse, check with your doctor.
  • Using Ameluz® with BF-RhodoLED® lamp may cause eye irritation or injury. It may also cause swelling of the eyelids. Tell your doctor right away if you have blurred vision, changes in vision, or red, sore eyes after receiving this medicine.

For Levulan® Kerastick® topical solution:

  • Avoid exposure to light if you experience stinging or burning on the treated areas before blue light treatment.
  • During the blue light treatment you will experience sensations of tingling, stinging, prickling or burning of the treated skin. These feelings of discomfort should improve at the end of the light treatment.
  • Following treatment, the actinic keratoses and possibly the surrounding skin will redden and swelling and scaling may also occur. These changes are temporary and should completely resolve after 4 weeks of treatment.

After aminolevulinic acid application, avoid exposure to sunlight or bright indoor light (eg, from examination lamps, operating room lamps, tanning beds, or being close to lights) up until the time of the blue or red light treatment. Wear long-sleeved shirts, gloves, or other protective clothing to shade the treated skin before blue light treatment. Wide-brimmed hats or similar head covering can help protect you from sunlight or sources of light. Sunscreens will not protect you from sunlight or sources of light.

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal (eg, St. John's wort) or vitamin supplements.
