What most people don't realize is that the majority of long-term, hard-core drug addicts are dying in their 40s and 50s. The latest studies show that the life expectancy of a drug addict is 15 to 20 years after they start being a drug addict. So what we see is a replenishment of the population, a new crop of addicts. There are no 90-year-old heroin addicts. Most of those we were recording 20 years ago have died.
The effects of drugs are measured in half-life which is the amount of time it takes for half of the drug dosage to be eliminated from your system. The fentanyl transdermal system (Duragesic patch) has a half-life of 17 hours.It is strongly recommended that patients not combine other opiods (like Percocet) with the patch, as this can result in an overdose. If her symptoms continue she should notify her doctor.Source(s): http://www.rxlist.com/cgi/generic/fentan...est Answer: Hi, Fentanyl has a half-life of about 7 hours (ie after 7 hours, half the drug remains. After another 7 hours, half of that ....etc). But the patches work by releasing fentanyl into body fats, which then slowly release the drug into the blood stream over 72 hours.
