Talk to your doctor before taking Fingolimod Olpha:
- if you have severe breathing problems during sleep (severe sleep apnoea).
- if you have been told you have an abnormal electrocardiogram.
- if you suffer from symptoms of slow heart rate (e.g. dizziness, nausea, or palpitations).
- if you are taking or have recently taken medicines that slow your heart rate (such as beta blockers, verapamil, diltiazem or ivabradine, digoxin, anticholinesteratic agents or pilocarpine).
- if you have a history of sudden loss of consciousness or fainting (syncope).
- if you plan to get vaccinated.
- if you have never had chickenpox.
- if you have or have had visual disturbances or other signs of swelling in the central vision area (macula) at the back of the eye (a condition known as macular oedema, see below), inflammation or infection of the eye (uveitis), or if you have diabetes (which can cause eye problems).
- if you have liver problems.
- if you have high blood pressure that cannot be controlled by medicines.
- if you have severe lung problems or smoker’s cough.
If any of these applies to you or you are unsure, talk to your doctor before taking Fingolimod Olpha.
Slow heart rate (bradycardia) and irregular heartbeat
At the beginning of treatment or after taking the first dose of 0.5 mg when you switch from a 0.25 mg daily dose, Fingolimod Olpha causes the heart rate to slow down. As a result, you may feel dizzy or tired, or be consciously aware of your heartbeat, or your blood pressure may drop. If these effects are severe, tell your doctor, because you may need treatment right away. Fingolimod Olpha can also cause an irregular heartbeat, especially after the first dose. Irregular heartbeat usually returns to normal in less than one day. Slow heart rate usually returns to normal within one month. During this period, no clinically significant heart rate effects are usually expected.
Your doctor will ask you to stay at the surgery or clinic for at least 6 hours, with hourly pulse and blood pressure measurements, after taking the first dose of Fingolimod Olpha or after taking the first dose of 0.5 mg when you switch from a 0.25 mg daily dose, so that appropriate measures can be taken in the event of side effects that occur at the start of treatment. You should have an electrocardiogram performed prior to the first dose of Fingolimod Olpha and after the 6-hour monitoring period. Your doctor may monitor your electrocardiogram continuously during that time. If after the 6-hour period you have a very slow or decreasing heart rate, or if your electrocardiogram shows abnormalities, you may need to be monitored for a longer period (at least 2 more hours and possibly overnight) until these have resolved. The same may apply if you are resuming Fingolimod Olpha after a break in treatment, depending on both how long the break was and how long you had been taking Fingolimod Olpha before the break.
If you have, or if you are at risk for, an irregular or abnormal heartbeat, if your electrocardiogram is abnormal, or if you have heart disease or heart failure, Fingolimod Olpha may not be appropriate for you.
If you have a history of sudden loss of consciousness or decreased heart rate, Fingolimod Olpha may not be appropriate for you. You will be evaluated by a cardiologist (heart specialist) to advise how you should start treatment with Fingolimod Olpha, including overnight monitoring.
If you are taking medicines that can cause your heart rate to decrease, Fingolimod Olpha may not be appropriate for you. You will need to be evaluated by a cardiologist, who will check whether you can be switched to alternative medicine that does not decrease your heart rate in order to allow treatment with Fingolimod Olpha. If such a switch is impossible, the cardiologist will advise how you should start treatment with Fingolimod Olpha, including overnight monitoring.
If you have never had chickenpox
If you have never had chickenpox, your doctor will check your immunity against the virus that causes it (varicella zoster virus). If you are not protected against the virus, you may need a vaccination before you start treatment with Fingolimod Olpha. If this is the case, your doctor will delay the start of treatment with Fingolimod Olpha until one month after the full course of vaccination is completed.
Infections
Fingolimod Olpha lowers the white blood cell count (particularly the lymphocyte count). White blood cells fight infection. While you are taking Fingolimod Olpha (and for up to 2 months after you stop taking it), you may get infections more easily. Any infection that you already have may get worse. Infections could be serious and life-threatening. If you think you have an infection, have fever, feel like you have the flu, have shingles or have a headache accompanied by stiff neck, sensitivity to light, nausea, rash and/or confusion or seizures (fits) (these may be symptoms of meningitis and/or encephalitis caused by a fungal or herpes viral infection), contact your doctor straight away, because it could be serious and life-threatening.
Human papilloma virus (HPV) infection, including papilloma, dysplasia, warts and HPV-related cancer, has been reported in patients treated with Fingolimod Olpha. Your doctor will consider whether you need to have a vaccination against HPV before starting treatment. If you are a woman, your doctor will also recommend HPV screening.
PML
PML is a rare brain disorder caused by an infection that may lead to severe disability or death. Your doctor will arrange magnetic resonance imaging (MRI) scans before you start treatment and during treatment to monitor the risk of PML.
If you believe your MS is getting worse or if you notice any new symptoms, for example changes in mood or behaviour, new or worsening weakness on one side of the body, changes in vision, confusion, memory lapses or speech and communication difficulties, talk to your doctor as soon as possible. These may be symptoms of PML. Also speak with your partner or caregivers and inform them about your treatment. Symptoms might arise that you might not become aware of by yourself.
If you get PML it can be treated and your treatment with Fingolimod Olpha will be stopped. Some people get an inflammatory reaction as Fingolimod Olpha is removed from the body. This reaction (known as immune reconstitution inflammatory syndrome or IRIS) may lead to your condition getting worse, including worsening of brain function.
Macular oedema
Before you start Fingolimod Olpha, if you have or have had visual disturbances or other signs of swelling in the central vision area (macula) at the back of the eye, inflammation or infection of the eye (uveitis) or diabetes, your doctor may want you to undergo an eye examination.
Your doctor may want you to undergo an eye examination 3 to 4 months after starting Fingolimod Olpha treatment.
The macula is a small area of the retina at the back of the eye which enables you to see shapes, colours, and details clearly and sharply. Fingolimod Olpha may cause swelling in the macula, a condition that is known as macular oedema. The swelling usually happens in the first 4 months of Fingolimod Olpha treatment.
Your chance of developing macular oedema is higher if you have diabetes or have had an inflammation of the eye called uveitis. In these cases, your doctor will want you to undergo regular eye examinations in order to detect macular oedema.
If you have had macular oedema, talk to your doctor before you resume treatment with Fingolimod Olpha.
Macular oedema can cause some of the same vision symptoms as an MS attack (optic neuritis). Early on, there may not be any symptoms. Be sure to tell your doctor about any changes in your vision.
Your doctor may want you to undergo an eye examination, especially if:
- the centre of your vision gets blurry or has shadows;
- you develop a blind spot in the centre of your vision;
- you have problems seeing colours or fine detail.
Liver function tests
If you have severe liver problems, you should not take Fingolimod Olpha. Fingolimod Olpha may affect your liver function. You will probably not notice any symptoms but if you notice yellowing of your skin or the whites of your eyes, abnormally dark urine (brown coloured), pain on the right side of your stomach area (abdomen), tiredness, feeling less hungry than usual or unexplained nausea and vomiting, tell your doctor straight away.
If you get any of these symptoms after starting Fingolimod Olpha, tell your doctor straight away.
Before, during and after the treatment your doctor will request blood tests to monitor your liver function. If your test results indicate a problem with your liver, you may have to interrupt treatment with Fingolimod Olpha.
High blood pressure
As Fingolimod Olpha causes a slight elevation of blood pressure, your doctor may want to check your blood pressure regularly.
Lung problems
Fingolimod Olpha has a slight effect on the lung function. Patients with severe lung problems or with smoker’s cough may have a higher chance of developing side effects.
Blood count
The desired effect of Fingolimod Olpha treatment is to reduce the amount of white blood cells in your blood. This will usually go back to normal within 2 months of stopping treatment. If you need to have any blood tests, tell the doctor that you are taking Fingolimod Olpha. Otherwise, it may not be possible for the doctor to understand the results of the test, and for certain types of blood test your doctor may need to take more blood than usual.
Before you start Fingolimod Olpha, your doctor will confirm whether you have enough white blood cells in your blood and may want to repeat a check regularly. In case you do not have enough white blood cells, you may have to interrupt treatment with Fingolimod Olpha.
Posterior reversible encephalopathy syndrome (PRES)
A condition called posterior reversible encephalopathy syndrome (PRES) has been rarely reported in MS patients treated with Fingolimod Olpha. Symptoms may include sudden onset of severe headache, confusion, seizures and vision changes. Tell your doctor straight away if you experience any of these symptoms during your treatment with Fingolimod Olpha, because it could be serious.
Cancer
Skin cancers have been reported in MS patients treated with Fingolimod Olpha. Talk to your doctor straight away if you notice any skin nodules (e.g. shiny pearly nodules), patches or open sores that do not heal within weeks. Symptoms of skin cancer may include abnormal growth or changes of skin tissue (e.g. unusual moles) with a change in colour, shape or size over time. Before you start Fingolimod Olpha, a skin examination is required to check whether you have any skin nodules. Your doctor will also carry out regular skin examinations during your treatment with Fingolimod Olpha. If you develop problems with your skin, your doctor may refer you to a dermatologist, who after consultation may decide that it is important for you to be seen on a regular basis.
A type of cancer of the lymphatic system (lymphoma) has been reported in MS patients treated with Fingolimod Olpha.
Exposure to the sun and protection against the sun
Fingolimod weakens your immune system. This increases your risk of developing cancers, in particular skin cancers. You should limit your exposure to the sun and UV rays by:
- wearing appropriate protective clothing.
- regularly applying sunscreen with a high degree of UV protection.
Unusual brain lesions associated with MS relapse
Rare cases of unusually large brain lesions associated with MS relapse have been reported in patients treated with Fingolimod Olpha. In case of severe relapse, your doctor will consider performing MRI to evaluate this condition and will decide whether you need to stop taking Fingolimod Olpha.
Switch from other treatments to Fingolimod Olpha
Your doctor may switch you directly from beta interferon, glatiramer acetate or dimethyl fumarate to Fingolimod Olpha if there are no signs of abnormalities caused by your previous treatment. Your doctor may have to do a blood test in order to exclude such abnormalities. After stopping natalizumab you may have to wait for 2-3 months before starting treatment with Fingolimod Olpha. To switch from teriflunomide, your doctor may advise you to wait for a certain time or to go through an accelerated elimination procedure. If you have been treated with alemtuzumab, a thorough evaluation and discussion with your doctor is required to decide if Fingolimod Olpha is appropriate for you.
Women of childbearing potential
If used during pregnancy, Fingolimod Olpha can harm the unborn baby. Before you start treatment with Fingolimod Olpha your doctor will explain the risk to you and ask you to do a pregnancy test in order to ensure that you are not pregnant. Your doctor will give you a card which explains why you should not become pregnant while taking Fingolimod Olpha. It also explains what you should do to avoid becoming pregnant while you are taking Fingolimod Olpha. You must use effective contraception during treatment and for 2 months after stopping treatment (see section “Pregnancy and breastfeeding”).
Worsening of MS after stopping Fingolimod Olpha treatment
Do not stop taking Fingolimod Olpha or change your dose without talking to your doctor first.
Tell your doctor straight away if you think your MS is getting worse after you have stopped treatment with Fingolimod Olpha. This could be serious (see “If you stop taking Fingolimod Olpha” in section 3 and also section 4 “Possible side effects”).
