Although naproxen isn’t an addictive medication in the traditional sense, long-term use could lead to some form of withdrawal. More than likely, though, there would be very few side effects of that withdrawal. If anything, a person may find they develop a tolerance to naproxen, making it less effective over time.
How long do naproxen withdrawal symptoms last?
Naproxen has an elimination half-life of 12 to 17 hours; however, there are no known withdrawal symptoms.
There are not likely to be side effects from withdrawal. The most significant impact might be the return of pain or inflammation that this drug was helping to manage.
There is no way to gauge risk because this drug is not addictive.
If pain returns, it might be necessary to take another form of pain reliever.
