### input:
I was on Amlodipine 10 mg and Digoxin .25 mg for over 15 years but was recently warned about the dangers of Digoxin. My cardiologist put me on Metoprolol 25 mg. with Amlodipine 5 mg but I put on 14 pounds in a month. I asked to be taken off Metoprolol because of the weight gain and was told to take Diltiazem 24 hr. ER 120 mg. My weight continues to rise. Oh, and I m also on Famatidine 20 mg. twice a day for acid reflux. My pressure shot up when I started taking Famatidine, so my doctor recommended taking Amlodipine 5 mg. with Diltiazem. I d like to drop everything and go back to Amlodipine. Is there a good substitute for Digoxin? My tachycardia is not a bad one and it only occurs when I drink too much coffee or eat lots of chocolate. If not, could I take Amlogipine 5 mg and Diltiazem 24 hr ER 120 mg together? Guess I ll need to go on a diet to lose those 14 pounds that I ve gained.

Hello, I have gone through your query. Thanks for using Chat Doctor.First let me tell you that your weight gain has nothing to do with Cessation of lanolin or starting of metoprolol or diltiazem. You are gaining weight due to either diet, lack of exercise or hereditary factor. You should check for thyroid functions test. Digoxin is not indicated for simple fast heart rate unless you have valvular heart lesion along with irregular heart beats, or you have a weak heart. I suggest you to try another Beta blocker like Nebivelol in consultation with your treating doctor, My best wishes Chat Doctor.
