My baby was prescribed Zantac for acid reflux. When should I notice a difference in her to determine whether it is working or not?Secondly, a friend advised that Prevacid works better for infant reflux. What is the difference between the two, and should I ask my doctor to switch?Thanks!

Doctor Bray,This is the guy who has been consulting

Hi Doctor Bray,This is the guy who has been consulting with you about petechiae for the past few weeks. My doc referred me to a haematologist/oncologist for further testing and my results showed a normal collagen epinephrine, but my collagen ADP was elevated 25 seconds beyond the reference range (value was 127 sec, with reference range topping out at 102). Could you please tell me what this might mean?

I have a chemical stress test on Monday and have been reading

I have a 'chemical stress test' on Monday and have been reading the latest FDA warnings against mixing the usual Lexiscan and Adenosine for the test (causing fatal heart attacks). My doctor is using Lexiscan with "99M Technictium Sestamibi"as the tracer. Does the same danger exist with THIS combination?

I am a 29-year-old female. I have had SVT (not WPW) for many

I am a 29-year-old female. I have had SVT (not WPW) for many years but was first diagnosed in 2010 when it was finally caught on an EKG. I have had two echocardiograms (one in 2010 and one at the beginning of this month) and both have shown that my heart is healthy and normal. I have a few questions I was hoping to get answers to:1) I have been told that SVT (since it is not WPW) is irritating but not life-threatening. Is this true?2) During my first pregnancy, my SVT symptoms returned during the third trimester (three episodes, though it should be noted that this was a time of extreme stress for me as I was finishing my PhD during this time). I was told that maternal SVT is not dangerous to a fetus, even if adenosine has to be administered, and that I should be able to safely get pregnant again. Is this accurate? Also, how much (if any) should I expect my SVT symptoms to increase during a second pregnancy? What treatment options would be available to me safely during pregnancy?2) I want to be on a medication that will allow me to become pregnant without adverse side effects to the fetus. I currently take 200 mg of Labetalol twice per day, and I took this throughout my first pregnancy with no complications for either myself or my daughter. I am aware that Labetalol can occasionally cause a baby to have lower, but not dangerously low, birth weight (this was not a problem for my daughter, who was 8 pounds and 14 ounces). Are there other risks in taking Labetalol throughout an entire pregnancy? Are there alternative medications that I should consider? Is Labetalol commonly prescribed for SVT?At this point, I am not interested in ablation. Even though the risks are low, the possibilities of permanent heart damage and/or the need for a pacemaker are not things I want to consider at my age.Thank you!

I am having breathing problems (Dyspnea on exertion) when going

I am having breathing problems (Dyspnea on exertion) when going up stairs, bending over (while gardening) and when tying my shoes. I get out of breath and sometimes light headed.My doctor did an EKG, which was normal. Because I am also having a hip problem, he ordered a stress test, but an Adenosine Nuclear Stress Test. He said if the stress test turns out normal, then he will send me to a Pulmonary physician.I called billing at the hospital where I will have the stress test to find out the cost of this test. It is $8,200. My out-of-pocket portion for this test is just under $3,000.My question is . . . in order to avoid the expense of the stress test, would it be advantageous for me to first see the Pulmonary physician in case there is a problem with my lungs? I'm sure if he gave me a breathing test it wouldn't be near $8,200. Then if his testing results are normal, then I would then go for the stress test.Shirley
