Before taking this medicine

You should not use Desyrel if you are allergic to it.

Do not use Desyrel if you have taken an MAO inhibitor in the last 14 days. There could be a dangerous drug interaction. MAO inhibitors include isocarboxazid, linezolid, methylene blue injection, phenelzine, tranylcypromine, and others.

After you stop taking Desyrel, you must wait at least 14 days before you start taking an MAOI.

Tell your doctor if you also take stimulant medicine, opioid medicine, herbal products, or medicine for depression, mental illness, Parkinson's disease, migraine headaches, serious infections, or prevention of nausea and vomiting. An interaction with Desyrel could cause a serious condition called serotonin syndrome.

  • seizures or epilepsy;
  • narrow-angle glaucoma;

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. An overdose can be fatal when Desyrel is taken with alcohol, barbiturates such as phenobarbital, or sedatives such as diazepam (Valium).

Does trazodone cause weight gain?

Does trazodone make you sleepy?
Trazodone can help you sleep, and sleepiness is a side effect of the medication. Doctors will sometimes prescribe trazodone for insomnia, particularly for people who have both depression and difficulty sleeping. However, the benefit of taking trazodone for insomnia is not well established. The American Academy of Sleep Medicine recommends that trazodone and other antidepressants only be used for insomnia when other treatments have failed or in patients who also have depression.

How long does trazodone stay in your system?
Trazodone is mostly cleared from a healthy adult’s body within 1 to 3 days after a single dose. Its half-life is 5 to 13 hours, and since it takes about 5.5 half-lives for a drug to leave the system, trazodone is typically eliminated in about 27 to 72 hours. Continue reading
Is trazodone a controlled substance or narcotic?

Can trazodone cause a false positive on a drug test?
Yes, trazodone has been shown to cause false positive results on urine drug tests for amphetamines, MDMA, and LSD. This potential for cross-reactivity is due to one of its primary metabolites, meta-chlorophenylpiperazine (m-CPP), which can interfere with specific immunoassay screenings. Continue reading
How long does it take for trazodone to work?
Trazodone may start to relieve depression 1 to 2 weeks after you begin taking it, but it can take up to 6 weeks for the full benefit of the medication to set in. Continue reading
