How Do You Switch From Effexor To Pristiq? I Tried Going Straight From 150 Effexor To 50 Pristiq. Should I Taper Effexor While Starting Pristiq? Will Pristiq Also Handle My Anxiety?

Answer

Hi -

As Judy says, we're not medical professionals, but there's pretty good information online about both drugs. Stopping a powerful drug like effexor should always be done with a gradual tapering off in dosage to avoid withdrawal symptoms. Those symptoms are more likely to happen when stopping effexor because it leaves the system very quickly. Missing even a single dose can cause problems. Dropping it overnight could cause you a lot of issues, such as dizziness, a sensation of electric shocks in your head, headaches etc - the specifics vary from one person to another.

You may not have felt much of this because pristiq is the active chemical that effexor turns into when it's in your blood stream. Nevertheless, this switch is a drastic reduction all at once in your system.

You really need to work with your doctor on this. I'm not sure why you would be switched from effexor to pristiq since they are so similar unless there are special problems you've having that the change might help. Anyway, I have no way of knowing and no ability to offer medical advice. So please consult with your doctor or psychiatrist right away.
