Before you begin taking a medication, be sure to inform your doctor of any medical conditions or Allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use Volibris (Ambrisentan).
Blood changes: Volibris (Ambrisentan) may decrease hemoglobin levels and cause anemia (not enough red blood cells in your blood). Hemoglobin is the protein in red blood cells that carries oxygen throughout your body. Your doctor will perform regular tests to monitor your blood for changes while you are taking Volibris (Ambrisentan). People who have anemia should talk to their doctor before taking Volibris (Ambrisentan). If you experience symptoms of anemia such as shortness of breath, feeling unusually tired, or pale skin, contact your doctor as soon as possible.
Fluid retention: Fluid buildup in the body can occur as a result of pulmonary arterial hypertension (PAH), but it can also be caused by Volibris (Ambrisentan). This swelling is usually mild to moderate. However, tell your doctor if you experience symptoms of severe, increased swelling of your hands, feet, ankles, and legs while taking Volibris (Ambrisentan).
Liver function: This medication may cause liver damage. Your doctor will monitor your liver function by performing regular liver function tests while you are taking Volibris (Ambrisentan). Be sure to tell your doctor if you experience any signs of liver problems, such as yellowing of the skin or whites of the eyes, abdominal pain, or dark urine. If you have liver disease, discuss with your doctor how Volibris (Ambrisentan) may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Volibris (Ambrisentan), and whether any special monitoring is needed.
