Important Safety Information

Serious Adverse Reactions:

Low blood cell counts. Low blood cell counts are common with PHYRAGO and can be severe, including low red blood cell counts (anemia), low white blood cell counts (neutropenia), and low platelet counts (thrombocytopenia). Your healthcare provider will do blood tests to check your blood cell counts regularly during your treatment with PHYRAGO. Call your healthcare provider right away if you have a fever or any signs of an infection during treatment with PHYRAGO.

Bleeding problems. Bleeding problems are common with PHYRAGO. Sometimes these bleeding problems can be serious and lead to death. Call your healthcare provider right away if you have: unusual bleeding or bruising of your skin, bright red or dark tar-like stools, decreased alertness, headache or change in speech.

Your body may hold too much fluid (fluid retention). Fluid retention is common with PHYRAGO and can sometimes be severe. In severe cases, fluid may build up in the lining of your lungs, the sac around your heart, or your stomach cavity. Call your healthcare provider right away if you get any of these symptoms: swelling all over your body, weight gain, shortness of breath, especially if this happens with low levels of physical activity or at rest, dry cough and chest pain when taking a deep breath.

Heart and blood vessel (cardiovascular) problems. PHYRAGO may cause heart problems, including an abnormal heart rate, a heart attack, or small strokes that last only a few minutes or a few hours, called transient ischemic attacks (TIAs). TIAs are often a warning sign that you are at risk for a more serious stroke. Your healthcare provider will monitor the potassium and magnesium levels in your blood and your heart function.

Pulmonary Arterial Hypertension (PAH). PHYRAGO may cause high blood pressure in the vessels of your lungs. PAH may happen at any time during your treatment with PHYRAGO. Your healthcare provider should check your heart and lungs before and during treatment with PHYRAGO. Call your healthcare provider right away if you have shortness of breath, tiredness, or swelling all over your body (fluid retention).

Severe skin reactions. PHYRAGO may cause skin reactions that can sometimes be severe. Get medical help right away if you get a skin reaction with fever, sore mouth or throat, or blistering or peeling of your skin or in the mouth.

Tumor Lysis Syndrome (TLS). TLS is caused by a fast breakdown of cancer cells. TLS can cause you to have kidney failure and the need for dialysis treatment, and an abnormal heartbeat. Your healthcare provider may do blood tests to check you for TLS. Call your healthcare provider or get emergency medical help right away if you develop any of these symptoms during treatment with PHYRAGO: nausea, vomiting, weakness, swelling, shortness of breath, muscle cramps and seizures.

Slowing of growth and development in children. Effects on bone growth and development in children have happened with dasatinib and can sometimes be severe. Your healthcare provider will monitor your child’s bone growth and development during treatment with dasatinib. Get medical help right away if your child develops bone pain.

Liver problems. PHYRAGO can cause liver problems. People who have had liver problems in the past may be at risk of getting liver problems with PHYRAGO. Your healthcare provider will monitor your liver function as needed during treatment with PHYRAGO. Call your healthcare provider or get medical help right away if you develop any symptoms of liver problems, including: stomach-area (abdominal) pain, yellowing of your skin or white part of your eyes, loss of appetite, bleeding, bruising or dark “tea-colored” urine.
