NORVIR may affect the way other medicines work and other medicines may affect how NORVIR works, which may cause serious side effects.

The list of drug interactions below is not complete.

Tell your doctor especially if you take the following medicines, as they may cause an increase in side effects if you take them with NORVIR: meperidine, nilotinib (Tasigna®) and dasatinib (Sprycel®), colchicine (Colcrys®, Col-Probenecid®, Colchine®), trazodone, sildenafil (Viagra®), tadalafil (Cialis®, Adcirca®), avanafil (Stendra™), vardenafil (Levitra®, Staxyn®), fluticasone (Advair Diskus®, Veramyst®, Flovent®, Flonase®), budesonide (Pulmicort®, Symbicort®, Rhinocort Aqua®, Entocort® EC), dexamethasone, prednisone (Rayos®), salmeterol (Serevent®), fentanyl (Abstral®, Actiq®, Lazanda®, Onsolis®, Duragesic®, Fentora®), and rivaroxaban (Xarelto®).

This is not a complete list of medicines. Ask your doctor or pharmacist if you are not sure what medicines you are taking or refer to the NORVIR patient information leaflet. Know the medicines you take. Keep a list of them to show your doctor or pharmacist when you get a new medicine. Do not start any new medicines while you are taking NORVIR without first talking with your doctor.

What are the possible side effects of NORVIR?

Liver disease. Some people taking NORVIR in combination with other anti-HIV medicines have developed liver problems, which may be life-threatening. Your doctor should do regular blood tests during your combination treatment with NORVIR. If you have chronic hepatitis B or C infection, you have an increased chance of developing liver problems. Tell your doctor right away if you have any of the following signs and symptoms: loss of appetite, pain or tenderness on your right side below your ribs, yellowing of your skin or eyes, or itchy skin.

Swelling of your pancreas (pancreatitis). NORVIR can cause serious pancreas problems, which may lead to death. Tell your doctor right away if you have nausea, vomiting, or stomach (abdominal) pain, as these may be signs of pancreatitis.

Changes in the electrical activity of your heart, called PR prolongation, can cause irregular heartbeats. Tell your doctor right away if you have dizziness, lightheadedness, an abnormal heartbeat, or feel faint or pass out.
