Visudyne 15 mg powder for solution for infusion
WHAT VISUDYNE IS AND WHAT IT IS USED FOR
What Visudyne is
Visudyne contains the active substance verteporfin, which is activated by light from a laser in a treatment called photodynamic therapy. When you are given an infusion of Visudyne, it is distributed within your body through the blood vessels, including the blood vessels at the back of the eye. When the laser light is shone into the eye, Visudyne is activated.
What Visudyne is used for
Visudyne is used to treat the wet form of age-related macular degeneration and pathological myopia.
These diseases lead to vision loss. Vision loss is caused by new blood vessels (choroidal neovascularisation) that damage the retina (the light-sensitive membrane that lines the back of the eye). There are two types of choroidal neovascularisation: classic and occult.
Visudyne is used for the treatment of predominantly classic choroidal neovascularisation in adults with age-related macular degeneration, and also for the treatment of all types of choroidal neovascularisation in adults with pathological myopia.
BEFORE YOU ARE GIVEN VISUDYNE
You should not be given Visudyne
- if you are allergic (hypersensitive) to verteporfin or any of the other ingredients of Visudyne.
- if you have porphyria (a rare condition that may increase sensitivity to light).
- if you have any severe liver problems.
If any of these apply to you, tell your doctor. You should not be given Visudyne.
Take special care with Visudyne
If you experience any problems or symptoms during the treatment such as chest pain, sudden loss of consciousness, sweating, dizziness, rash, breathlessness, flushing, irregular heart beat, please tell your doctor or nurse.
If you have any liver problems or a blockage of your bile duct, please tell your doctor before starting Visudyne therapy.
If, during the infusion, Visudyne goes outside the vein, and especially if the affected area is exposed to light, this can cause pain, swelling, blistering and a change in skin colour in the area of the leakage. If this happens, the infusion needs to be stopped and the skin treated with cold compresses and thoroughly protected from light until the skin colour returns to normal. You may need to take a painkiller.
You will be sensitive to bright light for 48 hours after the infusion. During that time, avoid exposure to direct sunlight, bright indoor lights such as in tanning salons, bright halogen lighting, high power lighting as used by surgeons or dentists, or light from light-emitting medical devices such as pulse oximeters (used to measure oxygen in blood). If you have to go outdoors during daylight in the first 48 hours after treatment, you must protect your skin and eyes by wearing protective clothing and dark sunglasses. Sunscreens offer no protection.
Normal indoor lighting is safe.
Do not stay in the dark because exposure to normal indoor lighting will help your body to eliminate Visudyne more quickly.
If you experience any eye problems after the treatment, such as a vision loss, talk to your doctor.
Using other medicines
Please tell your doctor, nurse or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription.
If you are taking any of the following medicines:
- tetracyclines or sulphonamides (used to treat bacterial infection),
- phenothiazines (used to treat psychiatric disorders, or nausea and vomiting),
- sulfonylurea (used to treat diabetes),
- medicines used to lower blood sugar,
- thiazide diuretics (used to reduce high blood pressure),
- griseofulvin (used to treat fungal infection) tell your doctor or pharmacist. This is important because taking these medicines may increase your sensitivity to light.
Pregnancy and breastfeeding
Visudyne has not been studied in pregnant women. It is important to tell your doctor if you are pregnant, if you think you may be pregnant or if you plan to become pregnant. You should only be given Visudyne if your doctor considers it absolutely essential. Verteporfin is excreted in human milk in low amounts. Please tell your doctor if you are breastfeeding. He/she will decide whether you should be given Visudyne. It is recommended that, if you are given Visudyne, you do not breastfeed for 48 hours after administration.
Ask your doctor or pharmacist for advice before taking any medicine.
Driving and using machines
After Visudyne treatment you may have some vision problems, such as abnormal or decreased vision, which may be temporary. If this happens to you, do not drive or use any tools or machines until your vision improves.
Important information about some of the ingredients of Visudyne
Visudyne contains small amounts of butylated hydroxytoluene (E321). This ingredient is irritant to eyes, skin and mucous membranes.
If you come into direct contact with Visudyne, you must therefore wash it off extensively with water.
HOW VISUDYNE IS USED
Treatment with Visudyne is a two-step process
- First your doctor or the pharmacist will prepare the Visudyne infusion solution. It will be administered by your doctor or nurse into a vein using a drip (intravenous infusion).
- The second step is the activation of Visudyne in the eye 15 minutes after the start of the infusion. Your doctor will put a special contact lens onto your eye and treat your eye using a special laser. It takes 83 seconds to deliver the laser dose required to activate Visudyne. During this time, you will have to follow your doctor’s instructions and keep your eyes still.
If necessary, Visudyne therapy can be repeated every 3 months, up to 4 times per year.
Use in children
Visudyne is a treatment for adults only and not indicated for the use in children.
If you are given more Visudyne than you should be
Overdose of Visudyne may prolong the time during which you are sensitive to light and you may need to follow the protection instructions given in section 2 for longer than 48 hours. Your doctor will advise you.
Overdose of Visudyne and light in the treated eye may result in severe vision decrease.
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
POSSIBLE SIDE EFFECTS
Like all medicines, Visudyne can cause side effects, although not everybody gets them. These side effects may occur with certain frequencies, which are defined as follows:
|Very common||affects more than 1 user in 10|
|Common||affects 1 to 10 users in 100|
|Uncommon||affects 1 to 10 users in 1,000|
|Rare||affects 1 to 10 users in 10,000|
|Very rare||affects less than 1 user in 10,000|
|Not known||frequency cannot be estimated from the available data.|
Most of the side effects are mild to moderate and will usually disappear a few days to a few weeks after treatment.
Common side effects
- Eye disorders: severe decrease of vision (loss of 4 lines or more within 7 days of treatment), visual disturbances such as blurred, hazy or fuzzy vision, flashes of light, decreased vision, and a change in the field of vision in the treated eye such as grey or dark shadows, blind spots or black spots.
- Infusion site side effects: as with other types of injections, some patients experienced pain, swelling, inflammation, and weeping from the infusion site.
- General disorders: feeling sick (nausea), sunburn-like reactions, tiredness, infusion-related reaction, primarily presented as back pain which may radiate to other areas, including but not limited to, the pelvis, shoulders or rib cage, and increased cholesterol.
Uncommon side effects
- Eye disorders: bleeding of the retina or into the vitreous humour (the clear gel-like substance that fills the eyeball behind the lens), and displacement of the retina in the treated eye.
- Infusion site side effects: as with other types of injections, some patients experienced bleeding at the infusion site, change in skin colour and hypersensitivity. If this happens to you, there will be increased sensitivity to light in that part of the skin until the green discolouration disappears.

Rare frequency side effects
- Eye disorders: lack of blood circulation to the retina or choroids (the vascular layer of the eye) in the treated eye.

- Infusion site side effects: as with other types of injections, some patients experienced blistering.
- General disorders: vasovagal reactions (light-headedness and fainting) and allergic reactions, which on rare occasions can be severe, have been reported. General symptoms can include headache, malaise (feeling unwell), fainting, sweating, dizziness, rash, hives, itching, breathlessness, flushing, or changes in blood pressure and heart rate. Infusion-related reaction, primarily presented as chest pain which may radiate to other areas, including but not limited to, the pelvis, shoulders or rib cage.
