Fingolimod is used in adults and children at least 10 years old to treat relapsing forms of multiple sclerosis (including clinically isolated syndrome, relapsing-remitting disease, and active secondary progressive disease).

Fingolimod may also be used for purposes not listed in this medication guide.

You should not use fingolimod if you are allergic to it, or if you have:

• severe heart failure (that required you to be in the hospital);
• a serious heart condition such as "sick sinus syndrome" or "AV block" (unless you have a pacemaker);
• long QT syndrome; or
• recent (within the past 6 months) heart attack, stroke, "mini-stroke" or TIA, chest pain (unstable angina), or other serious heart problem.

Some heart rhythm medications can cause unwanted or dangerous effects when used with fingolimod. Your doctor may change your treatment plan if you also use: amiodarone, disopyramide, dofetilide, flecainide, dronedarone, ibutilide, mexiletine, procainamide, propafenone, quinidine, or sotalol.

Before you take fingolimod, tell your doctor if you have never had chickenpox or received a varicella vaccine (Varivax). You may need to receive the vaccine and then wait 1 month before taking fingolimod.

Make sure you are current on all vaccines before you start taking fingolimod.

Tell your doctor if you have recently received a vaccine, or if you are scheduled to receive a vaccine.

Tell your doctor if you have ever had:

• fever or an active or chronic infection;
• a weak immune system (caused by disease or by using certain medicine);
• a heart rhythm disorder;
• chest pain (angina) or other heart problems;
• a heart attack or stroke, including "mini-stroke";
• high blood pressure;
• fainting;
• diabetes;
• skin cancer;
• sleep apnea, or other breathing disorder;
• an eye condition called uveitis; or
• liver disease.

Fingolimod may harm an unborn baby. Do not use if you are pregnant. Use effective birth control while taking fingolimod and for at least 2 months after your last dose. Tell your doctor if you become pregnant.

If you are pregnant, your name may be listed on a pregnancy registry to track the effects of fingolimod on the baby.

Ask a doctor if it is safe to breastfeed while taking this medicine.

Use Tascenso Odt (Oral) exactly as directed on the label, or as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended.

Get emergency medical help if you have signs of an allergic reaction: hives, difficult breathing, swelling of your face, lips, tongue, or throat.

Fingolimod may cause a brain infection that can lead to disability or death. Tell your doctor if you have problems with speech, thought, vision, or muscle movement. These symptoms can get worse quickly.

Fingolimod can affect your immune system (even 2 months after you've taken this medicine). You may get infections more easily, even serious or fatal infections. Call your doctor if you have:

• signs of a new infection--fever, night sweats, swollen glands, cold sores, cough, wheezing, diarrhea, weight loss;
• trouble speaking or swallowing, problems with balance or eye movement, weakness or prickly feeling; or
• swelling in your neck or throat (enlarged thyroid), menstrual changes, impotence.

Also call your doctor at once if you have:

• new darkened area on your skin, a sore that does not heal, a mole that has changed in size or color, a bump that looks shiny, pearly, or pink;
• vision problems such as increased sensitivity to light, blurred vision, having a blind spot or shadows in the center of your vision, or unusual color to your vision (may occur 3 to 4 months after you start taking fingolimod);
• new or worsened breathing problems;
• sores in your mouth and throat, cold sores, sores on your genital or anal area;
• new or worsening symptoms of multiple sclerosis at least 12 weeks after your last dose;
• sudden confusion, severe headache, weakness, vision loss, or seizure;
• increased blood pressure;
• a light-headed feeling, like you might pass out;
• heart problems--chest pain, slow or irregular heartbeats, and feeling dizzy or tired; or
• liver problems--nausea, loss of appetite, stomach pain (upper right side), tiredness, itching, dark urine, clay-colored stools, jaundice (yellowing of the skin or eyes).

Common side effects may include:

• headache, back pain;
• stomach pain, diarrhea;
• pain in your arms or legs;
• cough, stuffy nose, flu symptoms; or
• abnormal liver function tests.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

Fingolimod can increase your risk of skin cancer. Avoid sunlight or tanning beds. Wear protective clothing and use sunscreen (SPF 30 or higher) when you are outdoors.

Avoid receiving a "live" vaccine while taking fingolimod, and for at least 2 months after your treatment ends. The vaccine may not work as well while you are taking fingolimod. Receiving a "live" vaccine while taking fingolimod may cause you to develop a serious infection. Live vaccines include measles, mumps, rubella (MMR), rotavirus, typhoid, yellow fever, varicella (chickenpox), and zoster (shingles).
