Dear doctor,

I have stopped taking my medications, Effexor 75 mg for a few days. I am wondering when my dizziness and brain zaps would stop.

Hi,

Welcome to icliniq.com.

The sudden discontinuation of Venlafaxine (Effexor) particularly seemed to cause discontinuation symptoms during the first three to seven days.

Ideally, it should not be stopped abruptly. It should rather be decreased sequentially over two to three weeks. And, another strategy is to consider switching to Fluoxetine, which may suppress the discontinuation symptoms and it has little tendency to cause such symptoms itself; and then discontinuing that.

My advice is to wait for a few more days and if the symptoms still persist, meet your physician again and suggest to put on Fluoxetine.
