Drug Interaction Report

Consumer information for this interaction is not currently available.

MONITOR: Coadministration of hypoxia-inducible factor prolyl hydroxylase (HIF PH) inhibitors, such as vadadustat or daprodustat, with drugs that are known to increase the risk of gastrointestinal erosion may increase the risk of gastric or esophageal erosions. Serious erosions, including gastrointestinal bleeding and the need for red blood cell transfusions, were reported during vadadustat and daprodustat clinical trials. Patients with a history of gastrointestinal erosion, peptic ulcer disease, and current tobacco smokers and alcohol drinkers may be at higher risk of gastrointestinal injury.

MANAGEMENT: Caution is advised if vadadustat or daprodustat are coadministered with drugs that have a known risk of gastrointestinal erosion, including but not limited to NSAIDs, corticosteroids, oral bisphosphonates, oral potassium formulations, anticoagulants as well as certain chemotherapeutic agents (e.g., kinase inhibitors) and antibiotics. Patients should be advised to contact their physician if they develop potential signs and symptoms of gastrointestinal injury such as abdominal pain, hematemesis, trouble swallowing, chest or throat pain, and/or black, tarry stools.

Using daprodustat while smoking or drinking alcohol may increase the risk of side effects in the gastrointestinal tract such as stomach inflammation and bleeding. Talk to your doctor if you have any questions or concerns. You should seek immediate medical attention if you have signs and symptoms of gastrointestinal bleeding such as abdominal pain, coughing up or vomiting fresh or dried blood that looks like coffee grounds, black, tarry stools, trouble swallowing, or chest or throat pain. 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.
