How is verteporfin given?
Verteporfin is injected into a vein through an IV. You will receive this injection in a clinic or hospital setting. Verteporfin must be given slowly, and the IV infusion can take at least 10 minutes to complete.
Tell your caregivers if you feel any burning, pain, or swelling around the IV needle when verteporfin is injected.
You will receive laser light treatment to your eye(s) within 15 minutes after the start of your verteporfin infusion.
After receiving verteporfin, you must protect your eyes from natural sunlight and bright indoor light for at least 5 days.. For best protection, wear dark sunglasses whenever you are outdoors or while indoors under bright lighting.
You should not stay in the dark while you are indoors, as this can actually cause the drug to stay active in your body longer. It is best to spend your time in ambient indoor light such as indirect sunlight through a window, or low-wattage incandescent lighting. Avoid areas where you will be exposed to halogen or fluorescent light.
Your doctor will need to check your progress on a regular basis. Do not miss any scheduled appointments.
What happens if I miss a dose?
Since verteporfin is given by a healthcare professional only in preparation for laser light treatment, you will not be on a frequent dosing schedule.
Your doctor should check your condition every 3 months to determine if you need repeat treatment.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.
Overdose symptoms may include severely decreased vision.
What should I avoid after I receive verteporfin?
Verteporfin will make your eyes and your skin more sensitive to light. Natural sunlight and bright indoor light can expose you to harmful UV rays, which may cause severe sunburn or damage to your vision.
Avoid exposure to sunlight, tanning beds, bright halogen lights, or other bright lighting for at least 5 days after you are treated with verteporfin.
To avoid exposing your skin to sunlight, keep all parts of your skin covered with clothing. Sunscreen will not be effective in protecting you from UV rays during the 5-day period after you have received verteporfin.
