1. What is Gliolan and how is it used
Gliolan is used for the visualization of certain brain tumors (called malignant gliomas) during tumor surgery.
Gliolan contains a substance called 5-aminolevulinic acid (5-ALA). The uptake of 5-ALA is greater in tumor cells, which convert it into another similar substance. If the tumor is then exposed to blue light, this new substance emits a red-violet light that helps to better distinguish between normal tissue and tumor tissue. This helps the surgeon to remove the tumor and at the same time to respect the healthy tissue.
2. What you need to know before starting Gliolan treatment
Do not take Gliolan
- if you are allergic to 5-ALA or porphyrins;
- in case of acute or chronic porphyria, suspected or confirmed (hereditary or acquired disorders of certain enzymes in the heme synthesis pathway);
- in case of pregnancy, suspected or confirmed.
Warnings and precautions
Consult your doctor or pharmacist before starting to take Gliolan.
- For 24 hours after administration of this medication, protect your eyes and skin from intense light(for example, surgical lighting, direct sunlight, or concentrated interior bright light).
- If you have or have had aheart disease, you must inform your doctor. In this case, this medication should be used with caution as it may cause a drop in blood pressure.

Other medications and Gliolan
Inform your doctor or pharmacist if you are taking, have taken recently, or may need to take any other medication, especially those that may cause skin problems when the skin is exposed to intense light (for example, certain types of antibiotics), but also those obtained without a prescription (for example, St. John's Wort extracts or Hypericum perforatum).
A case of severe sunburn of 5 days' duration has been reported in a patient after use of this medication and St. John's Wort extract. Do not take any of these products during the 2 weeks following use of Gliolan.
Avoid using any other medication that may cause liver damage during the 24 hours following Gliolan administration.
Administration of Gliolan with food and beverages
This medication is usually used once, specifically 2-4 hours before anesthesia for surgery of certain brain tumors called gliomas. Do not eat or drink for at least 6 hours before the start of anesthesia.
Pregnancy and breastfeeding

3. How to Take Gliolan
This medication is a powder that must be mixed first, before use, with drinking water. This procedure will always be performed by a pharmacist or a nursing professional and never by you. The usual dose is 20 mg of 5-ALA HCl per kilogram of body weight. The pharmacist or nursing professional will calculate the exact dose you need and the amount of solution (in ml) you must drink. You will have to drink the prepared solution 2-4 hours before anesthesia.
If surgery is postponed more than 12 hours, it should be rescheduled for the next day or later. You can take another dose of this medication 2-4 hours before anesthesia.
If you take more Gliolan than you should
If you have taken more Gliolan than you should have, your doctor will decide what measures are necessary to prevent any problems, including sufficient protection from intense light (for example, direct sunlight).
If you forgot to take Gliolan
This medication is administered once on the day of surgery, 2-4 hours before the start of anesthesia. If you forgot to take this medication during this time period, it is not advisable to take it just before the start of anesthesia. In this case, both anesthesia and surgery should be postponed for at least 2 hours, if possible.
If you have any other questions about the use of this medication, ask your doctor or pharmacist.
4. Possible Adverse Effects
Like all medicines, this medicine can cause side effects, although not everyone will experience them.
The most serious side effects include mild alterations in blood cell counts (red and white blood cells, platelets), disorders affecting the nervous system (neurological disorders) such as partial paralysis affecting one side of the body (hemiparesis) and blood clots that can block blood vessels (thromboembolism). Side effects observed withgreater frequency are a feeling of discomfort (vomiting), a desire to vomit (nauseas) and a mild increase in some enzymes (transaminases, γ-GT, amylase) or bilirubin (a bile pigment produced in the liver by the destruction of the red pigment) in theblood.
Inform your doctor immediately if you experience any discomfort.
Side effects are divided into the following two categories:
- side effects immediately after taking Gliolan and before anesthesia
- side effects combined from Gliolan, anesthesia, and tumor resection.
After using Gliolan and before the start of anesthesia, the following side effects may occur:
Side effects that are infrequent (may affect up to 1 in 100 people):A feeling of discomfort (nauseas), decrease in blood pressure (hypotension), skin reactions (for example, exanthema, similar in appearance to a sunburn).
In combination with anesthesia and tumor resection, other side effects may occur:
Side effects that are very frequent (may affect more than 1 in 10 people):Mild alterations in blood cell counts (red and white blood cells, platelets) and a slight increase in some enzymes (transaminases, γ-GT, amylase) or bilirubin (a bile pigment produced in the liver as a result of the destruction of the red pigment of the blood) in the blood. These findings reach theirmaximum levels at 7-14 days after surgery. The changes will resolve completely within a few weeks. You will usually not experience any symptoms when these changes occur.
Side effects that are frequent (may affect up to 1 in 10 people):
A feeling of discomfort (nauseas), indisposition (vomiting), disorders affecting the nervous system (neurological disorders), such as partial paralysis of one side of the body (hemiparesia), total or partial loss of the ability to use or understand language (aphasia), epileptic seizures (convulsions) and blindness of half the visual field in one or both eyes (hemianopsia), and blood clots that can block blood vessels (thromboembolism).
Side effects that are infrequent (may affect up to 1 in 100 people):
Decrease in blood pressure (hypotension), swelling of the brain (cerebral edema).
Side effects that are very rare (may affect up to 1 in 10,000 people) or unknown frequency (cannot be estimated from available data):
