My brother was just diagnosed with hepatocellular cancer with portal vein embolism and was place on inderal ,dilaudid, and lactulose.  He developed a rash under his arms,back of thighs to buttocks, and groin area. Is this most likely from the elevated bilirubin, liver enzymes , etc.?
Hello, It could be a sign of homeostasis. Consult a dermatologist and get evaluated. If it is itchy antihistamine like cetirizine can be taken. Hope I have answered your query. Let me know if I can assist you further.
