Bumex and Tamiflu are used in very different patients, and the points in common are limited. The main shared element is that both meet regulatory standards for efficacy and safety and benefit from pharmacist oversight.
Key differences
Bumex belongs to Diuretics while Tamiflu belongs to Antiviral Medications. Indications, mechanisms and target populations differ. The comparison is most useful when a clinician has mentioned both medications and the patient wants to understand where each fits.
Mechanism and action
Bumex: Bumetanide blocks the Na-K-2Cl cotransporter in the thick ascending limb of the loop of Henle, producing potent natriuresis and diuresis. Tamiflu: Oseltamivir is a prodrug rapidly hydrolysed by hepatic esterases to the active metabolite oseltamivir carboxylate, which selectively inhibits the neuraminidase enzyme on the surface of influenza A and B viruses.
When Bumex is preferred
Bumex is approved for oedema in heart failure, hepatic cirrhosis or chronic kidney disease, and for refractory oedema unresponsive to other diuretics.
When Tamiflu is preferred
Tamiflu is approved in adults and children for the treatment of acute uncomplicated influenza A and B when started within 48 hours of symptom onset, and for post-exposure prophylaxis of influenza A and B in patients aged 1 year and older.

No — they belong to different classes and have distinct side-effect profiles. Each medication has its own prescribing information.
