A light-activated eye medicine
Verteporfin
A light-activated medicine given by drip then triggered by a special eye laser to treat certain retinal conditions.
What is Verteporfin?
Verteporfin is a light-activated medicine used in a treatment called photodynamic therapy for certain conditions at the back of the eye. It is given through a drip into a vein, and then a special low-power laser is shone into the eye to switch the medicine on just where it is needed, closing off the abnormal, leaky blood vessels. For a couple of days after treatment, the medicine makes your skin and eyes very sensitive to bright light and sunlight, so you must keep covered up and out of strong light to avoid severe burns or eye damage.
Education and reference only. This is a plain-language guide to Verteporfin — it deliberately contains no doses. Doses depend on the person, the brand and the reason for treatment, and belong with your prescriber. Always check the BNF, the product labelling (SmPC) and follow medical advice.
What it is
Verteporfin is a light-activated (photosensitising) medicine used in photodynamic therapy for certain retinal conditions, such as some forms of leaking blood vessels at the back of the eye. It is given as an infusion into a vein, where it travels to the abnormal vessels in the eye. A specialist then shines a particular low-power laser into the eye, which activates the medicine only in that area. It is a hospital procedure carried out by eye specialists, not a tablet or drop.
How it works
Verteporfin circulates harmlessly until it is switched on by a specific wavelength of laser light. When the eye specialist shines this special laser into the eye, it activates the medicine within the abnormal blood vessels, producing a reaction that damages and closes them off, reducing leakage that threatens central vision. Because the medicine is only activated where the laser is aimed, the treatment is targeted; but until it clears, your whole body remains sensitive to strong light, which is the source of the main precaution.

Practical use
How to take Verteporfin
General, dose-free guidance — always follow your prescriber's and the leaflet's specific instructions.
- It is given as a drip into a vein at the hospital, followed by a special laser shone into the eye by an eye specialist.
- For the period your clinic advises (usually a couple of days), avoid direct sunlight and bright light, as your skin and eyes will be very sensitive.
- Cover your skin with clothing, wear a wide-brimmed hat and dark sunglasses if you must go outside, and do not rely on ordinary sunscreen.
- Normal, gentle indoor lighting is fine and helps the medicine clear; it is bright light and sunlight you must avoid.
- Arrange not to drive home, as your vision may be blurred, and follow the exact light-protection timing you are given.
Weighing it up
Advantages & disadvantages of Verteporfin
Advantages
- A targeted treatment that can close off abnormal leaking blood vessels and help preserve sight in certain retinal conditions.
- The medicine is only activated where the laser is aimed, focusing the effect on the area that needs it.
- Offers an option for specific conditions that may not respond as well to other approaches.
Disadvantages
- Causes severe skin and eye sensitivity to light for a couple of days, needing strict light protection.
- Involves both an infusion and a laser procedure at the hospital, rather than a simple injection or drop.
- Vision can be blurred for a time afterwards, and more than one treatment may be needed.
Practical use
Good to know
The single most important thing to know about verteporfin is the severe light sensitivity it causes for a couple of days after treatment. While the medicine is in your body, ordinary bright light and especially sunlight can cause serious skin burns and eye damage, so you must avoid direct sunlight and bright indoor light, keep your skin covered with clothing, wear a wide-brimmed hat and dark sunglasses, and not rely on ordinary sunscreen, which does not protect against this kind of reaction. Gentle, normal indoor lighting is generally fine and even helps the medicine clear, but going outside in daylight without full cover is not. The infusion site can also be sensitive to light. After the laser, your vision may be blurred for a time and you should not drive until it settles. Always follow the exact aftercare timing your clinic gives you.
Who should not take it / use with caution
- People with porphyria (a condition causing extreme light sensitivity) or a known allergy to verteporfin should not have it.
- It is used with caution in significant liver problems, as the medicine is cleared by the liver.
- It is avoided in pregnancy and breastfeeding unless the specialist judges it clearly necessary.
Monitoring
- Eye examinations and scans to check how the treated vessels and your vision respond.
- Watching for signs of excessive light sensitivity or skin reactions in the days after treatment.
- Reviewing whether further treatments are needed and how your sight changes over time.
Side effects
- Severe sensitivity of the skin and eyes to bright light and sunlight for a couple of days, risking burns if not protected.
- Reactions at the drip site, headache, back pain during the infusion, or temporary blurred or reduced vision.
- Rarely, a serious drop in vision, a severe infusion reaction or a leak of the medicine into the skin around the drip, which needs protecting from light.
Key interactions
- Other medicines that increase light sensitivity (such as some antibiotics and water tablets) could add to the reaction.
- Tell the team about all your medicines, as some can affect how the medicine is handled or increase light sensitivity.
- Care is taken if it is combined with other eye treatments, which the specialist will plan.
Available as: Powder made into a solution and given as an infusion into a vein, then activated by an eye laser.
Answers
Verteporfin: frequently asked questions
Why must I stay out of the sun after treatment?
Verteporfin makes your skin and eyes extremely sensitive to bright light and sunlight for a couple of days, so exposure can cause serious burns; you must keep covered and avoid strong light for the time your clinic advises.
Can I sit in normal indoor light afterwards?
Yes, gentle ordinary indoor lighting is generally fine and even helps the medicine clear from your body; it is direct sunlight and bright light you must avoid.
Does sunscreen protect me?
No, ordinary sunscreen does not protect against this type of light reaction, so you must cover your skin with clothing, a hat and sunglasses rather than relying on sunscreen.
How is the treatment given?
The medicine is given as a drip into a vein, and then an eye specialist shines a special low-power laser into the eye to activate it only where it is needed.
Will my vision be affected straight away?
Your vision may be blurred for a time after the laser, so arrange not to drive home and let it settle as your clinic advises.
