Moderate

ritonavir ambrisentan

Applies to: Paxlovid (nirmatrelvir / ritonavir) and ambrisentan

Ritonavir may increase the blood levels and effects of ambrisentan. This can increase the risk of serious side effects such as liver damage, anemia, and fluid accumulation (particularly in the lungs). You may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. Contact your doctor immediately if you experience fever, chills, joint pain or swelling, unusual bleeding or bruising, skin rash, itching, loss of appetite, fatigue, nausea, vomiting, dark colored urine, and/or yellowing of the skin or eyes, as these may be signs and symptoms of liver damage. Also seek medical attention if you develop paleness, dizziness, fainting, swelling, unusual weight gain, difficulty breathing, and/or shortness of breath. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
