Anyone with thick, dense hair in the chosen treatment region should shave the area two days prior to treatment. Shave the treated region for at least three days following treatment. 3. Bring sun protection gear to your appointment to protect you during the incubation period and on the way home. We recommend bringing sunglasses, a wide-brimmed hat, and a scarf. If your hands or arms are being treated, you should wear gloves and long sleeves. The team has several side effects (such swelling, irritation, scabbing, crusting, and discomfort) that are significantly increased with ANY sun exposure, including INDIRECT exposure in the 96 hours following therapy. Cover the treatment area prior to leaving the office and throughout the duration of incubation. 3. Allow 2.5 hours at our office. This includes the 90–120 minute incubation period and the approximately 17 minute Blue Light activation period. 4. If history cold sores” or “fever blisters”) in the regions being treated, inform us so that we can prescribe medicine to reduce the likelihood of an outbreak following treatment. 5. Kindly inform us if you have any contraindications to PDT or Blue Light Therapy, such as pregnancy, lupus, porphyria, allergies, or intolerance to Levulan, PDT, or 400-450 nm blue light. 6. For one week prior to PDT, discontinue usage of all topical vitamin A preparations (such as Differi Retin-A and Tazorac). 1 month following your second treatment, you may resume these drugs. 7. Please notify us if you are taking any of the following medications, as they may exacerbate your reaction and increase your side effects: griseofulvin, sulfonamides (sulfamethoxazole/trimethoprim combinations such as Bactrim or Septra) and antipsychotic medications), and tetracyclines (doxycycline, tetracycline, minocycline). 8. Please keep in mind that the most common side effects of treatment are scaling/crusting, skin lightening and/or darkening (hyper/hyperpigmentation), and itching. These symptoms often resolve within 5-7 days but may last several weeks. 9. Please refrain from wearing jewelry to your visit if you are having an extremity treated. Due to the possibility of swelling, you will be advised to avoid wearing jewelry for three days following your treatment. Wearing jewelry can result in a loss of circulation and, in extreme cases, amputation. 10.
