Gaxenim 0.5 mg hard capsules EFG
fingolimod
Gaxenim contains the active substance fingolimod.
Gaxenim is used in adults and in children and adolescents (from 10 years of age and older) to treat relapsing-remitting multiple sclerosis (MS) (a disease where the immune system attacks the protective covering of the nerves), particularly in:
Gaxenim does not cure MS, but it helps to reduce the number of relapses and slow down the progression of physical disabilities due to MS.
MS is a chronic disease that affects the central nervous system (CNS), which includes the brain and spinal cord. In MS, inflammation destroys the protective covering (called myelin) that surrounds the nerves in the CNS and prevents the nerves from functioning properly. This process is called demyelination.
Relapsing-remitting MS is characterized by repeated attacks (relapses) of neurological symptoms that reflect inflammation occurring in the CNS. The symptoms vary from one patient to another, but usually include difficulties walking, loss of sensation in some part of the body (numbness), vision problems, or balance disorders. The symptoms of a relapse may disappear completely when the relapse is over, but some problems may persist.
Gaxenim helps to combat the immune system's attacks on the CNS by reducing the ability of certain white blood cells (lymphocytes) to move freely within the body and preventing them from reaching the brain and spinal cord. This limits the nerve damage attributed to multiple sclerosis. Gaxenim also reduces some of the immune responses of your body.
If any of the above applies to you or if you are not sure, tell your doctor before taking Gaxenim.
Consult your doctor before starting to take Gaxenim:
If any of the above cases apply to you or if you are unsure, tell your doctor before taking Gaxenim.
Slow heart rate (bradycardia) and irregular heartbeats
At the start of treatment or after taking the first dose of 0.5 mg, in the case that your previous dose of 0.25 mg once a day has been changed, Gaxenim causes a decrease in heart rate. As a result, you may feel dizzy or tired, be aware of your heartbeat, or your blood pressure may drop. If these effects are severe, tell your doctor as you may need immediate treatment.Gaxenim can also cause your heartbeats to become irregular, especially after the first dose. Irregular heartbeats usually return to normal in less than a day. The slow heart rate usually returns to normal within a month. During this period, clinically significant effects on heart rate are not expected.
Your doctor will ask you to stay in the office or hospital for at least 6 hours, with pulse and blood pressure checks every hour, after taking the first dose of Gaxenim or after taking the first dose of 0.5 mg, in the case that your previous dose of 0.25 mg once a day has been changed, so that appropriate measures can be taken in case of adverse effects that appear at the start of treatment. You will have an electrocardiogram before the first dose of Gaxenim and after the 6-hour monitoring period. Your doctor may continuously monitor your electrocardiogram during this time. If after the 6-hour period you have a very slow or decreasing heart rate, or if your electrocardiogram shows abnormalities, you will need to be monitored for a longer period (at least 2 hours more and possibly overnight, until this is resolved). The same may apply if you are resuming Gaxenim after a pause in treatment, depending on both the duration of the pause and how long you were taking Gaxenim before the pause.
If you have, or are at risk of having, irregular or abnormal heartbeats, if your electrocardiogram is abnormal, or if you have heart disease or heart failure, Gaxenim may not be suitable for you.
If you have suffered from sudden fainting spells in the past or a decrease in heart rate, Gaxenim may not be suitable for you. You will be evaluated by a cardiologist (heart specialist) who will advise you on how to start treatment with Gaxenim, including nighttime monitoring.
If you are taking other medications that can slow down your heart rate, Gaxenim may not be suitable for you. You need to be evaluated by a cardiologist, who will assess whether you can switch to alternative medications that do not decrease heart rate to allow treatment with Gaxenim. If the aforementioned change is impossible, the cardiologist will advise you on how to start treatment with Gaxenim, including nighttime monitoring.
If you have never had chickenpox
If you have not had chickenpox, your doctor will check your immunity to the virus that causes it (varicella-zoster virus). If you are not protected against the virus, you will likely need to be vaccinated before starting treatment with Gaxenim. If so, your doctor will delay the start of treatment with Gaxenim until one month after the vaccination cycle is completed.
Infections
Gaxenim reduces the number of white blood cells in your blood (especially the number of lymphocytes). White blood cells fight infections. During treatment with Gaxenim (and up to two months after treatment is stopped), you may be more likely to get infections. You may even have a worsening of an infection you already have. Infections can be serious and potentially life-threatening.
Human papillomavirus (HPV) infection, including papilloma, dysplasia, warts, and HPV-associated cancer, has been reported in patients treated with fingolimod. Your doctor will assess whether you need to be vaccinated against HPV before starting treatment. If you are a woman, your doctor will also recommend that you have HPV screenings.
LMP
LMP is a rare brain disorder caused by an infection, which can cause severe disability or death. Your doctor will perform magnetic resonance imaging (MRI) before starting treatment and during treatment to monitor the risk of LMP.
If you think your MS is getting worse or if you notice any new symptoms, such as changes in your mood or behavior, worsening or appearance of weakness on one side of your body, changes in vision, confusion, memory problems, or difficulties with speech and communication, tell your doctor as soon as possible. These may be symptoms of LMP. Also, talk to your family members or caregivers to inform them about your treatment. Symptoms may appear without you realizing it.
If you develop LMP, it can be treated, and your treatment with Gaxenim will be stopped. Some people have an inflammatory reaction when Gaxenim is removed from the body. This reaction (known as immune reconstitution inflammatory syndrome or IRIS) can cause a worsening of your disease, including a worsening of brain function.
Macular edema
Before starting treatment with Gaxenim, your doctor may request an eye examination if you have or have had visual disturbances or other signs of inflammation in the central vision area (macula) of the eye, eye inflammation or infection (uveitis), or diabetes.
After starting treatment with Gaxenim, your doctor may request an eye examination after 3 or 4 months of treatment.
The macula is a small area of the retina located at the back of the eye that allows you to see shapes, colors, and details clearly and sharply. Gaxenim can cause inflammation of the macula, and this condition is known as macular edema. Inflammation usually occurs within the first four months of treatment with Gaxenim.
If you have diabetesor have had eye inflammation known as uveitis, you are more likely to develop macular edema. In these cases, your doctor will want you to have regular eye checks to detect macular edema.
If you have had macular edema, consult your doctor before continuing treatment with Gaxenim.
Macular edema can cause the same visual symptoms as those produced in an MS attack (optic neuritis). At first, you may not have symptoms. You should inform your doctor of any changes you notice in your vision. Your doctor may want to perform an eye examination, especially if:
Liver function tests
If you have severe liver problems, you should not take Gaxenim. Gaxenim can affect liver function. You may not notice any symptoms, but if you notice a yellowish tone in your skin or the white part of your eye, abnormally dark urine (brown color), pain in your right side of the stomach (abdomen), fatigue, loss of appetite, or nausea and vomiting without apparent cause, tell your doctor immediately.
If you have any of these symptoms after starting treatment with Gaxenim, tell your doctor immediately.
Before, during, and after treatment, your doctor will request blood tests to check your liver function. You may need to stop treatment with Gaxenim if the results of your tests indicate a problem with your liver.
High blood pressure
Since Gaxenim causes a slight increase in blood pressure, your doctor will want you to have your blood pressure checked regularly.
Lung problems
Gaxenim has a mild effect on lung function. Patients with severe lung problems or "smoker's cough" are more likely to develop adverse effects.
Blood count
The expected effect of treatment with Gaxenim is to reduce the number of white blood cells in your blood. This effect usually returns to normal within 2 months after stopping treatment. If you need to have blood tests, tell your doctor that you are taking Gaxenim, as your doctor may not understand the results of the tests otherwise. For certain blood tests, your doctor may need more blood than usual.
Before starting treatment with Gaxenim, your doctor will check if you have enough white blood cells in your blood and may want to repeat checks regularly. If you do not have enough white blood cells, you may need to stop treatment with Gaxenim.
Posterior reversible encephalopathy syndrome (PRES)
A rare condition called posterior reversible encephalopathy syndrome (PRES) has been reported in MS patients treated with fingolimod. Symptoms may include sudden onset of severe headache, confusion, seizures, and changes in vision. Tell your doctor immediately if you experience any of these symptoms during treatment with Gaxenim, as it can be serious.
Cancer
Cases of skin cancer have been reported in MS patients treated with fingolimod. Tell your doctor immediately if you notice any nodules on your skin (e.g., shiny nodules with a pearl-like appearance), spots, or open sores that do not heal within weeks. Symptoms of skin cancer may include abnormal growth or changes in skin tissue (e.g., unusual moles) that change color, shape, or size over time. Before starting treatment with Gaxenim, a skin examination is required to check if you have any nodules on your skin. Your doctor will also perform regular skin checks during treatment with Gaxenim. If any skin problems appear, your doctor may refer you to a dermatologist, who may decide if it is important to visit you regularly.
A type of cancer of the lymphatic system (lymphoma) has been reported in MS patients treated with fingolimod.
Sun exposure and sun protection
Fingolimod weakens your immune system, which increases the risk of developing cancer, especially skin cancer. You should limit your exposure to the sun and UV rays by:
Unusual brain lesions associated with MS relapses
Rare cases of large and unusual brain lesions associated with MS relapses have been reported in patients treated with fingolimod. In the case of severe relapses, your doctor will assess the need to perform a magnetic resonance imaging (MRI) scan to evaluate your condition and decide if you need to stop taking Gaxenim.
Switching from other treatments to Gaxenim
Your doctor may switch you directly from interferon beta, glatiramer acetate, or dimethyl fumarate to Gaxenim if there are no signs of treatment-related abnormalities. Your doctor may need to perform a blood test to rule out such abnormalities. After stopping natalizumab, you may need to wait for 2-3 months before starting treatment with Gaxenim.
To switch from teriflunomide, your doctor may advise you to wait for a period or undergo an accelerated elimination procedure. If you have been treated with alemtuzumab, a thorough evaluation is necessary, and you should discuss it with your doctor to decide if Gaxenim is suitable for you.
Women of childbearing age
If Gaxenim is used during pregnancy, it may harm the fetus. Before starting treatment with Gaxenim, your doctor will explain the risks and ask you to take a pregnancy test to ensure you are not pregnant. Your doctor will give you a card that explains why you should not become pregnant while taking Gaxenim and what you should do to avoid becoming pregnant while taking Gaxenim. During treatment and for 2 months after stopping treatment, you must use an effective contraceptive method (see section "Pregnancy and breastfeeding").
MS worsening after stopping treatment with Gaxenim
Do not stop taking Gaxenim or change the dose your doctor has prescribed without discussing it with your doctor first.
Tell your doctor immediately if you think your MS is getting worse after stopping treatment with Gaxenim, as it can be serious (see section 3 "If you stop treatment with Gaxenim" and also section 4 "Possible side effects").
Experience with fingolimod in elderly patients (over 65 years) is limited. If in doubt, consult your doctor.
Gaxenim should not be administered to children under 10 years of age, as it has not been studied in patients with MS in this age group.
The warnings and precautions mentioned above also apply to children and adolescents. The following information is especially important for children and adolescents and their caregivers:
Tell your doctor or pharmacist if you are taking, have recently taken, or may need to take any other medication. Tell your doctor if you are taking any of the following medications:
If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor before using this medication.
Pregnancy
Do not use Gaxenim during pregnancy, or if you plan to become pregnant, or if you are a woman who can become pregnant and do not use an effective contraceptive method. If Gaxenim is used during pregnancy, there is a risk of harm to the fetus. The rate of congenital malformations observed in babies exposed to fingolimod during pregnancy is approximately 2 times higher than that observed in the general population (where the rate of congenital malformations is approximately 2-3%). The most frequently reported malformations include cardiac, renal, and musculoskeletal malformations.
Therefore, if you are a woman of childbearing age:
and
Your doctor will give you a card that explains why you should not become pregnant while taking Gaxenim.
If you become pregnant during treatment with Gaxenim, tell your doctor immediately.Your doctor will decide to stop treatment (see section 3 "If you stop treatment with Gaxenim" and also section 4 "Possible side effects"). You will receive specific prenatal follow-up.
Breastfeeding
Do not breastfeed during treatment with Gaxenim.Gaxenim passes into breast milk, and there is a risk that the baby may have serious side effects.
Your doctor will inform you if your illness allows you to drive vehicles, including bicycles, and use machines safely. It is not expected that Gaxenim will have an influence on your ability to drive and use machines.
However, at the start of treatment, you will have to stay in the doctor's office or hospital for 6 hours after taking the first dose of Gaxenim. During this time period and possibly afterwards, your ability to drive and use machines may be altered.
Excipients
This medication contains less than 1 mmol of sodium (23 mg) per hard capsule. This is essentially "sodium-free".
Treatment with Gaxenim will be supervised by a doctor with experience in the treatment of multiple sclerosis.
Follow the administration instructions of this medication exactly as indicated by your doctor. In case of doubt, consult your doctor again.
The recommended dose is:
The dose is one 0.5 mg capsule per day.
Children and adolescents (10 years of age and older):
The dose depends on body weight:
Since 0.5 mg hard capsules are not suitable for pediatric patients with a body weight ≤40 kg, other medications containing fingolimod are available in a lower concentration (such as 0.25 mg capsules).
For children and adolescents who start with a 0.25 mg capsule per day and later reach a stable weight greater than 40 kg, the doctor will indicate that they switch to a 0.5 mg capsule per day. In this case, it is recommended to repeat the observation period of the first dose.
Do not exceed the recommended dose. Gaxenim is used orally.
Take Gaxenim once a day with a glass of water. Gaxenim capsules should always be swallowed whole, without opening them. You can take Gaxenim with or without food.
Taking Gaxenim every day at the same time will help you remember when to take the medication.
If you have doubts about the duration of treatment with Gaxenim, consult your doctor or pharmacist.
If you have taken more Gaxenim than you should, inform your doctor immediately.
If you have been taking Gaxenim for less than 1 month and you forget to take 1 dose during a whole day, talk to your doctor before taking the next dose. Your doctor may decide to keep you under observation when you take the next dose.
If you have been taking Gaxenim for at least 1 month and you have forgotten to take your treatment for more than 2 weeks, talk to your doctor before taking the next dose. Your doctor may decide to keep you under observation when you take the next dose. However, if you have forgotten to take your treatment for a period of up to 2 weeks, you can take the next dose as planned.
Never take a double dose to make up for forgotten doses.
Do not stop taking Gaxenim or change the dose to be taken without discussing it with your doctor first.
Gaxenim will remain in your body for up to two months after treatment is interrupted. The number of white blood cells in the blood (lymphocyte count) may remain low during this period, and it is possible that the adverse effects described in this prospectus may still occur. After interrupting treatment with Gaxenim, you may have to wait during 6-8 weeks before starting a new treatment for MS.
If you need to resume treatment with Gaxenim after a pause of more than two weeks, the effect on heart rate that may occur at the start of treatment may repeat, and it will be necessary for you to be monitored in the doctor's office to restart treatment. Do not restart treatment with Gaxenim after interrupting it for more than two weeks without consulting your doctor.
Your doctor will decide if it is necessary to monitor you after interrupting treatment with Gaxenim and how to do it. Inform your doctor immediately if you think your MS is getting worse after interrupting treatment with Gaxenim, as it could be serious.
If you have any other doubts about the use of this medication, ask your doctor or pharmacist.
