Propranolol False Positives For Amphetamines And Opiates

Updated

I recently began taking propranolol for low blood pressure. I took a drug screen and it tested positive for amphetamines and opiates,however,I haven't taken anything but Goody Powders and my prescribed dosage of 10 mg of propranolol. Could someone tell me how it caused a false positive test result? Thank you very much for any help.

Your taking it for low blood pressure?

Propanolol is used to treat high blood pressure, because it helps to lower it.

Learn more Propranolol details here.

And it can cause a false positive for Amphetamines, but I can't really explain the specifics of why. However, in most cases, it's due to the quality of the test being used, the less expensive, non-certified tests have been known to give these false positive results anywhere from 4 to 50% of the time.

Did they send it out to a lab for further testing? Because the more precise testing done in a lab should eliminate the false positive.

As to the opiates, I am not sure what may have caused the false positive for them, since I don't know which powders you took to check the ingredients.

I take on occasionally Metformin , oct sudafed rubitussin nose spray and a few other prescription. norco, topimate, and some other cheap allergy meds. doc said there is no way anything over the counter will test positive for amphetamines . say i can disput it before he discharges me, but the nurse already had discharge papers in hand. think he was looking for excuse to discharge me. isn't that against some oth they take.lol

The nose spray can definitely create a false positive for methamphetamine because it contains pseudo ephedrine

I believe Propranolol can cause a false positive for both amphetamines and opiates.
