Vivactil - How long does the generic "protriptyline" take to leave your system?

Hi, katebug! Vivactil has an extremely long half-life of about 65-90hrs. This means that when you take your normal dose about half of it could still be in your system a few days later.
It's very important to give it plenty of time to clear if you're going to be starting any drug that might cause an interaction.
