Interactions between your drugs

Moderate

phenazopyridine bedaquiline

Applies to: Phenaz Plus (butabarbital / hyoscyamine / phenazopyridine) and Sirturo (bedaquiline)

Bedaquiline may cause liver problems, and using it with other medications that can also affect the liver such as phenazopyridine may increase that risk. You should avoid or limit the use of alcohol while being treated with these medications. Call your doctor immediately if you have fever, chills, joint pain or swelling, unusual bleeding or bruising, skin rash, itching, loss of appetite, fatigue, nausea, vomiting, abdominal pain, dark urine, pale stools, and/or yellowing of the skin or eyes, as these may be signs and symptoms of liver damage. Talk to your doctor or pharmacist if you have any questions or concerns. 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.
