Effexor and Brain Zaps, Electric shock like sensations

Are you currently tapering or coming off effexor? Effexor has a very short half life of 5 hours (they say its 11 hours if you take the extended release, which to me isn't entirely accurate). If you miss a dose, you will certainly experience brain zaps, or if you've taken your dose later than usual, that can also cause brain zaps. Im currently on effexor and experience brain zaps every day. At times they were so severe as if I had not taken my dose, when I had. I started splitting my dose into morning afternoon and that reduce the severity significantly. Everyone is different, so that may not help you if you have something similar going on. I came to the conclusion that I was experiencing interdose withdrawal. This isn't medical advice. Always speak to your prescriber before making any changes to your regimen.
