Tell your doctor if you have yellowing of the skin or eyes, darkening of the urine, or severe nausea or vomiting, as these could be signs or symptoms of liver problems. Rarely, failure of the liver to function (called acute liver failure) may occur, which can lead to death. Tell your doctor if you require vaccination or have come into contact with someone who has received a vaccine. Tell your doctor if you have tuberculosis and/or HIV. Androgen deprivation therapy (ADT), such as TERONRED 500, is associated with an increased risk of developing non-alcoholic fatty liver disease (NAFLD) and other liver conditions (such as cirrhosis (scarring), liver necrosis (cell death)). Non-alcoholic fatty liver disease or NAFLD is when there is accumulation of excess fat in the liver of patients who drink little or no alcohol. Decrease in red blood cells may occur. Tell your doctor if you start feeling tired and weak, have pale skin, suffer from shortness of breath, chest pain, get frequent infections, headaches, or feel dizzy (this could mean you may have anaemia). Reduced sex drive (libido), muscle weakness and/or muscle pain may occur. TERONRED 500 must not be given in combination with Ra-223 due to a possible increase in the risk of bone fracture or death. If you plan to take Ra-223 following treatment with TERONRED 500 and prednisone/prednisolone, you must wait 5 days before starting treatment with Ra-223. If you have diabetes, your blood sugar may drop if you take TERONRED 500 plus prednisone/prednisolone with some medicines for diabetes such as pioglitazone or repaglinide.
