A patient was prescribed Warfarin but just before being discharged from the Hospital, his doctors changed the type of medication from Warfarin to RIVAROXABN (XARELTO®).
A few months later, the patient presented to the department of emergency with the son requesting for Warfarin refill. After one week, the patient had a surgery clinic appointment where the son requested for RIVAROXABN (XARELTO®) refill.
The patient presented to the department of emergency after one month with gastrointestinal bleeding and high (International Normalization Ratio (INR) was 11) and the patient was admitted to the Intensive Care Unit. The patient was taking RIVAROXABN (XARELTO®) while she was already on Warfarin. This combination led to severe Drug-Drug interaction.
