What is Ponvory?

• Ponvory is a prescription medicine that is used to treat relapsing forms of multiple sclerosis, to include clinically isolated syndrome, relapsing remitting disease, and active secondary progressive disease, in adults.
• It is not known if this medicine is safe and effective in children.

Ponvory side effects

The most common side effects of Ponvory include:

• upper respiratory tract infections
• elevated liver enzymes (abnormal liver tests)
• high blood pressure.

Serious side effects

Ponvory may cause serious side effects, including:

Infections. Ponvory can increase your risk of serious infections that can be life-threatening and cause death. Ponvory lowers the number of white blood cells (lymphocytes) in your blood. This will usually go back to normal within 1 to 2 weeks of stopping treatment. Your healthcare provider should review a recent blood test of your white blood cells before you start treatment and may delay starting or stop your treatment if you have an infection. Call your healthcare provider right away if you have any of these symptoms of an infection during treatment with Ponvory and for 1 to 2 weeks after your last dose:

• fever
• vomiting
• tiredness
• headache with fever, neck stiffness, sensitivity to light, nausea, or confusion (these may be symptoms of meningitis, an infection of the lining around your brain and spine)
• body aches
• chills
• nausea.
  
  

Slow heart rate (bradycardia or bradyarrhythmia) when you start taking Ponvory. Ponvory can cause your heart rate to slow down, especially after you take your first dose. You should have a test to check the electrical activity of your heart called an electrocardiogram (ECG) before you take your first dose. Only start your treatment using the Starter Pack. You must use the Starter Pack to slowly increase the dose over 14 days to help reduce the effect of slowing your heart rate. Call your healthcare provider if you experience the following symptoms of slow heart rate:

• dizziness
• shortness of breath
• lightheadedness
• confusion
• feeling like your heart is beating slowly or skipping beats
• chest pain
• tiredness.

Breathing problems. Some people who take Ponvory have shortness of breath. Call your healthcare provider right away if you have new or worsening breathing problems.

Liver problems. Ponvory may cause liver problems. Your healthcare provider should do blood tests to check your liver before you start treatment. Call your healthcare provider right away if you have any of the following symptoms of liver problems:

• unexplained nausea
• loss of appetite
• vomiting
• yellowing of the whites of your eyes or skin
• stomach (abdominal) pain o dark urine
• tiredness.

Increased blood pressure. Your healthcare provider should check your blood pressure during treatment.

Types of skin cancer, including basal cell carcinoma (BCC), melanoma, and squamous cell carcinoma. Certain types of skin cancer have happened with drugs in the same class. Tell your healthcare provider if you have any changes in the appearance of your skin, including changes in a mole, a new darkened area on your skin, a sore that does not heal, or growths on your skin, such as a bump that may be shiny, pearly white, skin-colored, or pink. Your doctor should check your skin for any changes during treatment. Limit the amount of time you spend in sunlight and ultraviolet (UV) light. Wear protective clothing and use sunscreen with a high sun protection factor.

A problem with your vision, called macular edema. Tell your healthcare provider about any changes in your vision. Your healthcare provider should test your vision before you start treatment and any time you notice vision changes during treatment with Ponvory. Your risk of macular edema is higher if you have diabetes or have had an inflammation of your eye called uveitis.
Call your healthcare provider right away if you have any of the following symptoms:

• blurriness or shadows in the center of your vision
• sensitivity to light
• a blind spot in the center of your vision
• unusually colored (tinted) vision.

Swelling and narrowing of the blood vessels in your brain. A condition called Posterior Reversible Encephalopathy Syndrome (PRES) has happened with drugs in the same class. Symptoms of PRES usually get better when you stop taking Ponvory. However, if left untreated, it may lead to a stroke. Call your healthcare provider right away if you have any of the following symptoms:

• sudden severe headache
• sudden loss of vision or other changes in your vision
• sudden confusion
• seizures.

Severe worsening of multiple sclerosis (MS) after stopping Ponvory. When Ponvory is stopped, symptoms of MS may return and become worse compared to before or during treatment. Always talk to your healthcare provider before you stop taking Ponvory for any reason. Tell your healthcare provider if you have worsening symptoms of MS after stopping Ponvory.

Longer treatment durations of Ponvory (more than 18 months) increase the risk of developing progressive multifocal leukoencephalopathy (PML), a rare brain infection.

These are not all of the possible side effects. For more information, ask your healthcare provider or pharmacist. Call your healthcare provider for medical advice about side effects. You may report side effects to the FDA at 1-800- FDA-1088.

  Talk to your healthcare provider before taking Ponvory if you have any of these conditions, or do not know if you have any of these conditions.

• medicines that affect your immune system, such as alemtuzumab.
• medicines such as rifampin, phenytoin, or carbamazepine.
• You should not receive live vaccines during treatment, for at least 1 month before, and for 1 to 2 weeks after you stop treatment. If you receive a live vaccine, you may get the infection the vaccine was meant to prevent. Vaccines may not work as well when given during treatment with Ponvory.

Talk with your healthcare provider if you are not sure if you take any of these medicines. Know the medicines you take. Keep a list of your medicines with you to show your healthcare provider and pharmacist when you get a new medicine.

• If you miss taking 1, 2, or 3 tablets in a row of Ponvory while taking the 20 mg maintenance dose, continue treatment with the 20 mg maintenance dose.
