Alcoholism

Major:

Panamax

The acetaminophen in Panamax has a major potential interaction with Alcoholism.

Chronic alcohol abusers may be at increased risk of hepatotoxicity during treatment with acetaminophen (APAP). Severe liver injury, including cases of acute liver failure resulting in liver transplant and death, has been reported in patients using acetaminophen. Therapy with acetaminophen should be administered cautiously, if at all, in patients who consume three or more alcoholic drinks a day. In general, patients should avoid drinking alcohol while taking acetaminophen-containing medications. Patients should be warned not to exceed the maximum recommended total daily dosage of acetaminophen (4 g/day in adults and children 12 years of age or older), and to read all prescription and over-the-counter medication labels to ensure they are not taking multiple acetaminophen-containing products, or check with a healthcare professional if they are unsure. They should also be advised to seek medical attention if they experience signs and symptoms of liver injury such as fever, rash, anorexia, nausea, vomiting, fatigue, right upper quadrant pain, dark urine, and jaundice.

Autoimmune Disorders

Moderate:

avelumab

Avelumab has a moderate potential interaction with Autoimmune Disorders.

Programmed death receptor-1/ligand-1 (PD-1/PD-L1) blocking antibodies can cause immune-mediated adverse reactions, which may be severe or fatal. Immune-mediated adverse reactions can occur in any organ system or tissue at any time after starting therapy. This may be considered when using PD-1/PD-L1 blocking antibodies in patients with immune system disorders (e.g., ulcerative colitis, Crohn's disease, lupus) or with conditions affecting the nervous system (e.g., myasthenia gravis, Guillain-Barre syndrome). It is recommended to monitor patients closely for signs/symptoms that may be clinical manifestations of underlying immune-mediated adverse reactions.

Bone Marrow Transplantation

Moderate:

avelumab

Avelumab has a moderate potential interaction with Bone Marrow Transplantation.

Fatal and other serious complications can occur in patients who receive allogeneic hematopoietic stem cell transplantation (HSCT) before or after being treated with a programmed death receptor-1/ligand-1 (PD-1/PD-L1) blocking antibody. Transplant-related complications include hyperacute graft-versus-host disease (GVHD), acute GVHD, chronic GVHD, hepatic veno-occlusive disease after reduced intensity conditioning, and steroid-requiring febrile syndrome (without an identified infectious cause). These complications may occur despite intervening therapy between PD-1/PD-L1 blockade and allogeneic HSCT. It is recommended to follow patients closely for evidence of transplant-related complications and intervene promptly. The benefit versus risks of treatment with a PD-1/PD-L1 blocking antibody before or after an allogeneic HSCT should be considered.
