How long does Ephedrine stay in your system?

[natron]

metabolites of ephedrine can cause a positive test for amphetamines for about 4-6 days if I remember correctly

dont you have to be taking in large amounts of it though?

[natron]

No.

Like many things it depends on the type of drug test they are going to use. not all pee tests are equal. At the place I work, we are pretty cheap with our testing, but amphetamines about 2 to 3 days. But better tests test the levels of the chemicals as the break down further. Also, the test has to be designed to also test for ephradrine...It might not be in the test they are even using.

Most drug test that take place because of company policies do test for amphetamines, and ephedrine will more thna likely cause a false positive.

You can either stop a week or so before testing, if you aware of the testing that is. Or, you can tell them you use ephedrine as a bronchodilator, and they will make the necessary adjustments. Ephedrine use is NOT illegal, and can be distinguished between methanphetamine and the like, if that is what they are looking for.

Anyhow,

BUMP an old thread.

I have a general physical today at my doctor. I know that Ephedrine stays in the system for a few days but does anybody know how long the effects on blood pressure and heart rate last?

I took a dose at 8:30am and the physical is at 4:30pm this afternoon. I wont be dosing again today.

Thanks.

Not sure, but my BP goes from around 110/78 to 130/80 when I am on an EC stack. However, the day after I go off the stack my BP goes back to normal. I would have skipped this morning's dose, but since its about 8 hours later you may have an elevated BP.

It has a half-life of 3-6 hours. In four half lives, it should be cleared from your system (12-24 hours).

It doesn't slow down? I know in engineering we solve via the integral for chemical degradation and a half life of something say 3-6 hours could still be around a week or so later.

Generally, pharmacologists consider 4 half lives to be the standard for full drug elimination. You are correct however, since ephedrine is metabolized with 1st order elimination kinetics, its elimination would be proprotional to the drug concentration, and therefore slow down as a function of concentration.

1st half life --> 50% eliminated
2nd half life --> 75%
3rd half life --> 87.5%
4rth half life --> 93.75%

Awesome info and good post, bro.. repped. (measley)
