Verteporfin
About Verteporfin
Verteporfin is a specialised medicine injected into the bloodstream to treat abnormal blood vessel growth in the back of the eye. It is primarily used to help prevent severe vision loss in people with specific eye conditions, such as the classic 'wet' form of age-related macular degeneration. By targeting and closing these leaking blood vessels, it helps protect your remaining eyesight.
This treatment is not a daily medication. It is given as a single intravenous infusion followed shortly after by a non-heat laser treatment, and your doctor may repeat the procedure every three months if necessary. To get the best results, you must strictly avoid exposing your skin and eyes to direct sunlight or bright indoor light for several days after each treatment.
While undergoing this treatment, you may experience temporary side effects like vision changes, dry eyes, or irritation where the medicine was injected. It is important to contact your eye doctor immediately if you notice a sudden, severe drop in your vision or severe skin reactions.
Do not take this if you have porphyria, a rare metabolic disorder that increases light sensitivity. Before starting treatment, tell your doctor if you have liver problems or any other medical conditions, as this may affect how your body processes the medicine.
Some medicines can make your skin even more sensitive to light, so tell your doctor about all drugs you are taking, especially other light-sensitizing medications. If you are pregnant, planning to become pregnant, breastfeeding, or are an elderly patient, discuss the benefits and risks with your healthcare provider first.
Uses of Verteporfin
Medicinal Benefits
Using Verteporfin as prescribed helps preserve vision, reduce retinal damage, and slow the progression of certain eye diseases. Here are the key benefits you can expect:
- Helps preserve vision: Slows the progression of vision loss by sealing abnormal blood vessels and protecting the retina from further damage.
- Reduces retinal swelling and scarring: Helps stop leakage from abnormal blood vessels, reducing swelling and lowering the risk of permanent retinal scarring.
- Supports daily independence: By maintaining central vision, it helps many people continue everyday activities such as reading, recognising faces, and driving more safely, where appropriate.
Directions for Use
- Verteporfin will be administered by a healthcare professional.
- Do not self-administer it.

Side Effects of Verteporfin
Common Side Effects (Usually mild):
- Temporary vision changes, such as blurry, hazy, or dim vision
- Pain, redness, swelling, or bruising at the injection site
- Dry eyes, itchy eyes, or a feeling of something in the eye
- Tiredness, headache, or mild weakness
Serious Side Effects (Consult your doctor right away):
- Sudden, severe decrease in vision or complete vision loss
- Severe pain, blistering, or swelling at the injection site (which could mean the medicine leaked into surrounding skin tissue)
- Severe skin reactions, such as blistering, severe sunburn, or swelling after exposure to light
- Signs of a severe allergic reaction, such as hives, difficulty breathing, or swelling of your face, lips, or throat
Drug Warnings
- Check for leakage during infusion: Tell your doctor or nurse immediately if you feel any burning, stinging, or pain in your arm while the injection is being given. If the medicine leaks into the surrounding tissue, it can cause severe light-induced burns and tissue damage.
- Wear your light-sensitivity wristband: You may be given a wristband or warning card to wear after treatment to remind healthcare workers of your temporary sensitivity to bright light in case of an emergency.
- Delay dental or surgical procedures: Avoid any medical or dental procedures that require bright examination lights for 5 days after your treatment.
- Do not rely on standard sunscreen: Keep in mind that topical sunscreens do not protect against the light-sensitivity reactions caused by this medicine. Only physical shade and protective clothing will work.
Drug Interactions
- Other photosensitizing medicines: Taking drugs like tetracyclines (antibiotics), sulfonamides, phenothiazines (mental health medications), or sulfonylureas (diabetes medications) can severely increase your risk of skin burns from light.
- Vasodilators or vasoconstrictors: Medicines that change blood flow or affect blood vessels can alter how Verteporfin reaches the blood vessels in your eye.

Habit Forming
Diet & Lifestyle Advise
- Avoid direct sunlight: Stay indoors and avoid direct sunlight for exactly 5 days after your treatment. Do not use tanning beds during this time.
- Protect your skin: If you must go outside during the first 5 days, wear protective clothing, including long sleeves, pants, gloves, and a wide-brimmed hat. Normal sunscreens will not protect your skin from reactions caused by this medicine.
- Protect your eyes: Wear dark, professional-grade sunglasses that block ultraviolet and visible light when outdoors or in bright indoor spaces for 5 days.
- Manage indoor lighting: Avoid bright halogen lights or high-intensity examination lights. Use normal indoor lighting, as staying in complete darkness is not recommended; mild indoor light actually helps break down the medicine in your skin safely.
Patients Concern
Disease/Condition Glossary
Wet form of age-related macular degeneration: Age-related macular degeneration is an eye disease that causes vision loss. In wet macular degeneration, leaky blood vessels grow under the retina, which causes loss of the ability to see straight ahead and difficulty reading, driving or performing daily activities.
Pathological myopia: Pathologic myopia is a serious form of near-sightedness that worsens with time. Symptoms may include reduced vision even with vision correction, blind spots, straight lines that appear wavy, floaters, flashes, and difficulty reading, driving or performing daily activities.
Ocular histoplasmosis: It is an eye condition that develops in people with a lung infection called histoplasmosis. If the person has histoplasmosis, the infection can move from the lung into the eye, leading to vision loss. Symptoms include blurry vision and blind spots.
FAQs
Verteporfin is used to treat Wet form of age-related macular degeneration, pathological myopia, or ocular histoplasmosis.
Verteporfin is activated by light and closes up leaking blood vessels.
Verteporfin may cause sensitivity to sunlight. Avoid direct sunlight and bright indoor lights for 5 days after treatment with Verteporfin. If you must go outdoors during the first 5 days, wear protective clothing, a wide-brimmed hat, gloves, and dark sunglasses.
It is best to stay indoors as much as possible for the first 5 days. If you must go outside, you must wear protective clothing like long sleeves, a wide-brimmed hat, and dark sunglasses. Talk to your doctor for detailed instructions.
This medicine is designed to slow down or prevent further vision loss by sealing leaking blood vessels. It usually does not restore vision that has already been lost due to scarring. Talk to your doctor about what to expect.
Keeping your home in complete darkness actually delays the process of clearing the medicine from your body. Normal, low-intensity indoor light helps safely break down the drug in your skin. Talk to your doctor if you need advice on lighting.
Tell your healthcare provider immediately if you feel pain, burning, or swelling in your arm. This could mean the medicine is leaking out of the vein, which can cause severe skin burns. Talk to your doctor or nurse if you feel discomfort.
No, you should not drive yourself home. Your eyes will be dilated and highly sensitive to light, making it unsafe to drive. Please arrange for someone to take you home after your appointment. Talk to your doctor about safe travel plans.
Most patients are evaluated every 3 months. Your eye doctor will examine your retina and decide if you need another treatment based on whether the blood vessels are still leaking. Talk to your doctor to understand your specific treatment plan.
No, standard sunscreens do not protect against the specific light-sensitivity reactions caused by this medicine. You must rely on physical barriers like long clothing and staying indoors. Talk to your doctor for more safety tips.
