fentanol patch
how long does it take to get out your system
COMMUNITY LEADER
Hello~I think everyone's system is different, therefore, it probably takes longer in sme than others. I went to a google site, and here is what I found out:
The amount of time it takes for the amount of drug in the body to reduce by 50% is called the half-life. It takes approximately five to six half lives for the drug to be cleared from the body. The half-life for fentanyl patches is 9.5 to 12.4 hours. Multiply that by 6 and it could take up to 74.4 hours to clear the drug.You can do the math. Fentanyl lozenges-approx. 7 hours.
Hope this helps.
