how long does it take for amitriptyline to leave your system
Best Answer: Normal doses of the drug are metabolzed by the liver then the by-products are excreted in the urine. Its elimination half-life varies from 10 to 50 hours, with an average of 15 hours.One-half to one-third of a normal dose is excreted within 24 hours.Using that info, she should be drug-free anywhere from 6 to 20 days. That is of course if her liver function OK. She will probably have residual nervous system effects for some time. Hard to predict.r. said it will take some time but didn't have any idea how long. Her speech is still slurred and every fifteen minutes or so she goes to sleep, it reminds me of narcolepsy, she'll just collapse. It's been 2 wks. now. Does anyone know if this may cause brain damage.
