Which of the following medications should generally be avoided when taking warfarin?

Explanation

Warfarin interacts with several drugs that can affect its anticoagulant effect. Among these, nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen should be avoided due to increased risk of bleeding. Antacids, benzodiazepines, and opioids such as codeine and paracetamol generally have fewer interactions with warfarin.
