Contents of the pack and other information
The active ingredient in Foscan is temoporfin.
Foscan is a porphyrin photosensitising medicine, which increases your sensitivity to light and is activated by light from a laser in a treatment called photodynamic therapy.
Foscan is used for the treatment of head and neck cancer in patients who cannot be treated with other therapies.
if you are allergic to temoporfin or any of the other ingredients of this medicine (listed in
section 6),
if you are hypersensitive (allergic) to porphyrins,
if you have porphyria, or any other disease that is made worse by light,
if the tumour being treated goes through a large blood vessel,
if you are going to have an operation in the next 30 days,
if you have an eye disease which needs examination with bright light in the next 30 days,
if you are already being treated with a photosensitising agent.
Foscan will make you sensitive to light for about 15 days after your injection. This means that normal daylight or bright indoor lighting could give you skin burns. To stop this, you must follow carefully the instructions for gradual exposure to increasing light levels indoors over the first week and outdoor, shaded light during the second week after treatment (please see the table at the end of this leaflet).
Please speak to your doctor about this before you go home after being injected with Foscan.
Sunscreen creams will not prevent this sensitivity.
You will gradually become less sensitive to light. Normally, people are able to begin to return to normal outdoor lighting after 15 days.
For 6 months following Foscan treatment, avoid prolonged direct sunlight exposure of the injection site arm. As a precautionary measure, if prolonged outdoor activity is planned, protect your injection arm by wearing long sleeved, coloured clothing.
Please ask your doctor or nurse if you are not sure about anything.
Time after Foscan Injection | What should I do to prevent burns? |
Day 1 (0-24 hours) | Stay indoors in a darkened room. Keep the curtains drawn and use light bulbs of 60 W or less. Avoid exposure to direct sunlight. |
Days 2-7 | You can gradually return to normal indoor lighting. Remember to avoid direct sunlight coming through the window or direct light from household appliances such as reading lamps. You may watch television. You can go outdoors after dusk. If it is absolutely necessary to go outdoors during the hours of daylight, you must be careful to cover up all your skin including your face and hands and wear dark glasses. The type of clothes you must wear are: strong light. Wear dark, closely woven clothing. Your eyes may be very sensitive to bright lights during this week. You may get eye pain or headache when lights are switched on. If you have this problem, wear dark glasses. |
Days 8-14 | You can now begin to go outside during daylight hours. Stay in shaded areas or go out when it is cloudy. Continue to wear dark, closely woven clothing. |
Wide-brimmed hat: for head, neck, nose and ears.
Scarf: for head and neck.
Sunglasses with side panels: for eyes and skin around eyes.
Long sleeved top: for upper body/arms.
Long trousers: for lower body/legs.
Gloves: for hands, wrist and fingers.
Socks: for feet and ankles.
Closed shoes: for feet.
Do not wear very thin clothing because it will not protect you from
If you expose yourself to light by mistake, you may get a prickly or burning feeling on the skin. You must get out of the light immediately.
Start on Day 8 with 10-15 minutes outdoors. If you do not see any skin redness in the next 24 hours, you can gradually increase your time outdoors during the week. Avoid direct sunlight or strong indoor lighting. Stay in the shade. | |
Day 15 onward | Your sensitivity to light is gradually getting back to normal. You must test this carefully by exposing the back of your hand to the sun for 5 minutes. Wait 24 hours to see if there is any redness. If there is redness, you should avoid direct sunlight for another 24 hours. You can then repeat the test. If there is no redness, you can gradually increase your exposure to sunlight day by day. Do not stay in the sunlight for more than 15 minutes the first time. Most people will be able to go back to their normal routine by Day 22. On the first day after the skin test, you can stay in direct sunlight for 15 minutes. You can increase your exposure by another 15 minutes each day i.e. second day 30 minutes, third day 45 minutes, fourth day 60 minutes and so on. If at any time you notice a prickly or burning feeling or see skin reddening after exposure to sun, wait until this disappears before exposing your skin to light for this length of time again. For 30 days following Foscan treatment, avoid eye tests that use bright lights. For 3 months following Foscan treatment, avoid UV tanning beds. Do not sunbathe. For 6 months following Foscan treatment, care should be taken to avoid direct prolonged sunlight exposure of the arm used for Foscan injection. As a precautionary measure, if prolonged outdoor activity is planned, the injection arm should be protected by wearing long sleeved, coloured clothing. |
Tell your doctor if you are using, have recently used or might use any other medicines.
You must avoid becoming pregnant for 3 months after Foscan treatment.
Ask your doctor or pharmacist for advice before taking any medicine if you are pregnant.
The amount of alcohol in this medicine may impair your ability to drive or use machines for a few hours after injection.
It is not recommended to drive or operate machines for the first 15 days after Foscan injection, because of the recommended light exposure restrictions
This product contains 48 vol % ethanol (alcohol), i.e up to 4.2 g per dose, equivalent to 84 ml of beer, 35 ml wine per dose. This product is also harmful for those suffering from alcoholism. Pregnant or breast-feeding women, children and high-risk groups such as patients with liver
disease or epilepsy are also at risk.
Your doctor or nurse will give you Foscan by a slow injection into a vein, which will take approximately 6 minutes.
Four days after your injection, your doctor will treat your cancer with laser light. Your doctor will cover the normal tissue surrounding your cancer and then shine the laser light directly at the cancer for about 5 minutes. The laser light is not hot and will not burn.
You may not be given the laser treatment.
You may be sensitive to light for more than 15 days.
You must follow carefully the instructions on preventing skin burns.
Like all medicines, Foscan can cause side effects.
Everyone who takes Foscan will become sensitive to light for about 15 days after injection.
You must follow the instructions given to you to avoid sunlight and bright indoor light.
These instructions are written in this leaflet. Your doctor will also tell you what to do.
Most of the side effects related with photodynamic therapy are local effects seen as consequence of triggering the Foscan with the laser. You may feel pain after the laser treatment. This pain will be controlled with painkillers. Please let your doctor or nurse know if you have pain or if the painkillers you have been given are not taking the pain away. Furthermore you will probably notice swelling and reddening around the area that has been treated. You may be given some medicine to reduce the swelling. After 2 to 4 days, the treated area will turn black. This blackness is caused by dead cancer cells (necrosis). Foscan may also damage the tissue that is surrounding the tumour.
You may feel some pain when Foscan is injected.
After the laser treatment, you may feel pain in the treated area, e.g. pain in your face or headache.
There may also be bleeding, ulcers, swelling in the treated area like swelling of your face or tongue, and scarring.
You may get constipation.
These effects may make it difficult to eat and drink.
There may be some irritation, a burning sensation or skin damage where Foscan is injected, but this will not last long.
You may also get ulcers, blisters, skin redness, or skin darkening.

PACK CONTENTS
The active substance is temoporfin. Each ml of solution contains 1 mg of temoporfin. The excipients are ethanol anhydrous and propylene glycol. A filter with Luer lock connections for syringe and cannula is provided.
Each pack provides 1 vial containing 1 ml, 3 ml or 6 ml solution for injection. Each vial represents a single dose and any unused solution must be discarded.
CALCULATION OF DOSE
Calculate the required dose of Foscan according to the bodyweight of the patient. The dose is
0.15 mg/kg bodyweight.
ADMINISTRATION OF FOSCAN (96 hours prior to laser illumination of treatment site)
Foscan must be administered intravenously via an in-dwelling cannula in a large proximal limb vein, preferably in the antecubital fossa. The patency of the in-dwelling cannula should be tested before injection.
The dark purple colour of the solution together with the amber vial makes a visual check for particulates impossible. Thus, an in-line filter must be used as a precautionary measure and is provided in the package.
Draw up the entire contents of the vial containing Foscan into a syringe and expel air (Figure 1).
Figure 1
Attach the filter to the syringe (Figure 2).
Figure 2
Press the syringe plunger to fill all dead space within the filter. Continue pressing the plunger to expel excess Foscan until the required volume is left in the syringe, allowing sufficient to cover the dead space in the intravenous cannula (Figure 3).
Figure 3
Attach the syringe and filter to the cannula. Administer the required dose of Foscan by slow intravenous injection, over not less than 6 minutes (Figure 4).
Figure 4
Special care should be taken to prevent extravasation at the injection site. If extravasation occurs, protect the area from light for at least 3 months. There is no known benefit from injecting the extravasation site with another substance.
Foscan is photosensitive. Once removed from its packaging it should be administered immediately. Where delay is unavoidable, the solution must be protected from light.
LASER ILLUMINATION OF TREATMENT SITE
96 hours after the administration of Foscan, the treatment site is to be illuminated with light at 652 nm from an approved laser source. Light must be delivered to the entire surface of the tumour using an approved microlens fibre-optic. Wherever possible, the illuminated area must extend beyond the tumour margin by a distance of 0.5 cm.
Light must be administered not less than 90 hours and not more than 110 hours after Foscan injection. The incident light dose is 20 J/cm2, delivered by the microlens fibre-optic in a circular field to the
tumour surface at an irradiance of 100 mW/cm2, implying an illumination time of 200 seconds.
Each field is to be illuminated once only at each treatment. Multiple non-overlapping fields may be illuminated. Care must be taken to ensure that no area of tissue receives more than the specified light dose. Tissue outside the target area must be shielded completely to avoid photoactivation by scattered or reflected light.
SAFETY INFORMATION
Foscan is non-irritant.
Any unused medicinal product or waste material should be disposed of in accordance with local requirements.
