Hydrocodone Urine Test Negative

Updated

Why would my urine test show negative for Norco when I take 3-4 daily? I take 80mg daily of Lasix and I have stage 4 kidney failure. Could this be why my 8 panel test is coming back negative?

No. I too take lasix. Lasix will only dilute THC. The only reason why it isn't there is because you wasn't taking it period

This is bull I too take my meds. EVERYDAY, I NEED them, I had a tree limb fall on my back and mess me up till I could hardly get up and walk. So don't tell me it isn't possible for anyone to take the meds to help and get a neg. On a urine test. Maybe instead of being such a self righteous thinking you know it all. Since there is so many of us out there, why don't you do some testing and research.

Not true! If you drink a lot of water which I do because my lasix makes me thirsty it does affect it due to the fact you are flushing out your system - I am running into the same problem and my and my old Doctor I had before I moved made me cut back on my water intake to 12 ounces a day - low and behold my tests were coming out positive again!

I spoke to my regular doctor and told her about all the research I had done about neg. results in urine test after it happen to me. She she was going to check in to this and try to start researching this on her own, she could not believe how many people I polled and printed to take with me to my appointment to back me up.

Not true! I take four a day, every day, and my last two tests have come up negative as well. I am totally shocked about it! My Dr said that my liver is metabolising it out of my system quickly for some reason.

That is exactly what I have had to do and I also am on Lasix - they have now reduced me to 2 2.5/325 a day!!! I can tell you that with a bad hip and back and a muscle tear in my bicep this is not going over well -

Why would you take Norco's if your in stage four kidney failure? Norcos contain Tylenol which is lik deadly to your kidneys especially at that point in the game. If the have been prescribed ask them to switch you to either Vicodin(which is norco or lortab without the buffers), or Tylox(which is Percocet without the Tylenol) your DR should have already done this.

I am a dialysis patient. I do dialysis three times a week, 3 and a half hrs. per treatment. I take norco 7.5mg 3 times a day. My pain management doctors are telling me I am showing negative results for the norco. Why is that?

I have RA and take hydrocodone. Why is it not showing up in my urine test? Now my doc thinks I'm selling it and won't give it to me. This is crazy. My docs attitude towards me is different.

I agree with Jeannie... I am also prescribed 40MG of Lasix daily because of congestive heart failure to maintain the correct fluid amounts in my body, but am also prescribed Norco 10-325 every 4-6 hours as needed after a fumbled back surgery for chronic pain...I've been on the Norco for over 10 years and when I started the Lasix 5 years ago, my first 2 urine tests came back negative for the Norco, they said one more negative and my Norco would no longer be prescribed...third also came back negative, so I requested a blood test right then...came back positive of course.

Re: Sam (# 9) Expand Referenced Message

Mmm... Tylenol is dangerous for someone with liver problems or when took in a high dosage. Actually the National Kidney Foundation recommends the active ingredient "acetaminophen "to those who have underlying kidney disease. Rather than non steroidal anti- inflammatory medication like Aleve, aspirin, advil, or motrin.

I just got back from an appointment at ivy pain managment. I have 4 herniated discs in my lumbar, and 2 in my neck. I was taking 4 10mg norcos everyday and took 4 the day before my urine test. It came back negative and she cut me off and wouldn't fill my prescription. She sent me to get blood work done the next day. 2 hours before my blood test I chewed a norco to guarantee it would pop up. She left me hanging for 2 weeks before calling me back in and telling me it still came back negative. I was in complete shock and asked how that was medically or scientifically possible for that matter. She just rolled her eyes like I was lying to her or playing games. I'm not abusing my pills or selling them, I NEED THEM. Now Im left with nothing and no new appointments and I don't know what to do. She clearly stated I was completely fine.
