My husband had bypass sugary in Feb 2010. He takes 4 BP meds: Enalapril 20mg, Amlodipine 5mg, Diltiazen 120mg and Teva Spironolactone. His BP readings are very low: 94/56, 99/59, 89/51 readings today. Pulse rate is 78-81. He is experiences dizziness regularly. Slightest exertion causes dizziness. It is interfering with his quality of life. He thinks his BP is too low and I think he is right. He wants to stop taking Diltiazen to see if this will alleviate the dizziness. Our GP keeps telling him that his BP is where he wants it. We are waiting to get back into the cardiologist but this can take weeks if not months. How can he safely taper off the Diltiazen until we can see the cardio doctor? We want to see if coming off one of the meds will alleviate his dizziness. Thanks.
