The blood is first filtered by the kidneys, and the composition of the resulting fluid is then altered depending on the body's needs. It is composed of mostly water, and breakdown products from blood cells impart ...Read more
Can a urine,drug screen detect,the levels of my prescription vyvanse (lisdexamfetamine) all month or just detect that the drug is,there?
Only the presence: urine drug levels do not generally accurately reflect the blood levels (and even less so the brain levels) of any drug. Most of the time, drug tests look for metabolites of the drug, many of which are not even pharmacologically active. So, while they can say that you had a substance on board, they cannot say with any accuracy that you are on a low or high dose, or the right dose. ...Read more

Does taking a beta agonist for asthma and a beta blocker for high blood pressure counter act each other in any way?
Possibly: Avoid beta blockers during active asthma/bronchospasm as the airway issues could worsen. That said, when asthma is in the past and not an active concern, then some beta blockade might work and be tolerated. Would try to use beta 1 selective agents in such a case. ...Read moreSee 1 more doctor answer

Beta HCG : A very good question. The pills and injections given in the "hcg diet" will cause blood and urine levels of bhcg to rise. However, two measurements, a week or more apart, should differentiate between pregnancy ( where the levels will rise predictably) and diet drugs, assuming you are taking a constant dose for the diet treatments. ...Read more
Under which circumstances will a "normal" E.Coli gain on its activity? Is a positive serum beta glucuronidase test related to such activity? TY.
Hard to say/depends: This likely depends on what is considered "normal" about the E. coli and it's activity. E. coli is part of the normal "gut" flora. It's when certain other forms of E. coli like the O157:H7 strain get in the digestive tract that issues occur. So it's hard to say how activity would be affected unless abnormal E. coli get in there. The Bgluc test is homologous to the E. coli Bgalact enzyme. ...Read more
Is my psychiatrist in the position to demand a blood panel 9? And would the drug appear in urine test or blood test she wrote CBC deff/tsh cmp uds 9
Lab work: The doctor ordered CBC with differential (which is blood cells count with count of different cell classes) TSH (which is thyroid stimulating hormone) cmp (which is comprehensive metabolic panel) uds 9 (which is urine drug screen 9-drug panel). All those are routine orders and any psychiatrist would need to know the results to properly assess a patient. There is no reason to suspect of your doctor. ...Read moreSee 1 more doctor answer

Is a potassium level of 77.1 and a sodium level of 94 normal for a random urine sample? I did not have the 24 urine test done.
Incomplete: There are "normal values" for these tests. The Na is compared to the blood (or serum). You can do a "spot urine Cr to potassium" to estimate the potassium, but even this is not perfect. Something is missing from this information. Why was it done? What type of doctor did these test. You need to discuss this with the doctor who did these tests to see what he/she is looking for. ...Read moreSee 1 more doctor answer

Is it typical to be required to stop beta blocker prior to EP study? I've been taking propranolol for 5 years, 3 x daily. How can I do this?
Yes; taper off / 1wk: Beta blockers can suppress arrhythmias, & the EP study is a provocative test (trying to induce an arrhythmia to see where it's coming from). Stopping beta blockers abruptly can cause "rebound" increases in blood pressure, so the usual method is to taper off. Talk to the EP doc who scheduled the EP study to determine how the taper should be done. (I usually say 1/2 dose every 3 days, but that's me) ...Read more

Why is it that propranolol, a beta-blocker drug is given to a patient with double outlet right ventricle?
To relax the heart: Some patients with double outlet right ventricle have abnormally thick muscle bundles that block the flow of blood to the lungs when the heart contracts. When the blockage is severe the oxygen level in the body can drop to dangerous levels. Beta blockers such as Propranolol reduce the strength of the heart's contraction allowing more blood to pass to the lungs and can improve the oxygen level. ...Read more
Lopressor (metoprolol tartrate) 25 mg made me feel bad. Propranolol made me feel fine but i need a selective beta blocker. Which should I try?
Atenolol: Try atenolol - 12.5 to 100 mg (25 to 50 mg are the most usual doses). Atenolol is a beta 1 specific beta blocker that has the least ability to cross the blood brain barrier of all available beta blockers. It has no intrinsic sympathomimetic activity. It is intrinsically long acting and generally is given as a once a day dose. It's also dirt cheap! ...Read more

Usually Yes.: Your dose of Propranolol er 80 mg daily is high so you will need bystolic (nebivolol) 10 mg at least to begin with and may even need higher. Switch cane be made without weaning although there will be some initial withdrawal such as palpiatations or rise in pulse rate and BP but should not last longer. ...Read moreSee 1 more doctor answer
What would you recommend as best beta blocker with least side effects to treat my SVT? Propranolol & metoprolol made me too dizzy.
Dose dependent: It's not so much the med as the dose - since the side effect of all BBs is to lower BP. If your BP becomes too low, you'll get dizzy. That said, the BB I like the best for SVT is nadolol. The usual dose is 20-80 mg once a day, but for you, I'd recommend starting at 10 mg once a day and if you tolerate it, think about increasing the dose. ...Read more
