What to do if I had 50 mg of trazodone two days ago and am still feeling the effects. How long does it take to wear off?

That is my short ans: 50 mgm trazadone, 48 hours later you still have the effects.
You probably went to see an md with some complaints, which included sleep disturbance. He gave you trazadone and you sort of sleeping since then.
Time for total truth.

Can low dose trazadone help to reduce benzodiazepine use and withdrawal?

Yes: trazodone is definitely a better alternative for sleep. Chronic use of benzos leads to tolerance and rebound insomnia. Just make sure you taper and do not stop benzo abruptly and consult with prescribing doc. If you are a resident of CA I would be happy to provide a virtual consult. If not consider a virtual consult with a Healthtap psychiatrist who is licensed in your state ...Read more

I took a trazadone and I've heard it can cause a false positive for urine screens, I only took 50mg. How long before it's out of my urine completely?

I took a trazadone and I've heard it can cause a false positive for urine screens, I only took 50mg. How long before it's out of my urine completely?

5 x its half life: A drug is considered gone after about 5 half lives. Trazodone has a biphasic elimination with a redistribution of about one hour and an elimination of half-life of 10-12 hours. To be safe I would wait at least 50 hours and hydrate well before taking the urine drug test. Use of trazodone a triazolopyridine antidepressant can yield a false positive amphetamine result. ...Read more

False positive?: Some nonsteroidal medications can cause false positives for benzodiazepines: daypro, tolmetin (tolectin) Naproxen (aleve) Etodolac (lodine) and fenoprofen (nalfon).

I tested positive for benzodiazepine march 6th 2014, after taking 4 kolopin 1mg february 14 2014, why is this still showing up in my urine?

Very long half-life: Klonopin (clonazepam) has a very long elimination half-life: 18-60 hours. It takes 5 of these half-lives to effectively eliminate the Klonopin (clonazepam) from your system (supposing you're not still taking it). So depending on your metabolism this could take 12-14 days. If you're still taking a few of the pills, this would also register positive. ...Read more

Are you asking...: Are you asking: could his test still be positive two weeks later from a single dose? Yes. Of course, this does not guarantee this result was from that specific dose unless you are sure it was the only dose. Perhaps one question: why was your 15 year old son tested? ...Read more
