My father is on eloquist, lasix, and blood pressure medications. Would any of these interact badly with Tamaflu? Mom has the flu and they put Dad on Tamaflu because he has begun with a cough and sore throat. He reports his heart racing and shortness of breath last night. It became better when he started using is ipap machine. You shoud know that Dad has pulmonary hypertenstion, heart failure, compromised kidneys, and severe sleep apnea.
