Venlafaxine and Side Effects

I have malignant vaso vagal syndrome which has been treated with dual chamber pace maker.  I have also started with severe tiredness and confusion since I have been prescribed with with 150 mg of venlafaxine.  I am struggling to cope with household and work functions and feel my brain is not able to concentrate I also feel detached.  I have been dizzy and had severe bod tremors.  Feel zombie like.  Could the medication be causing this or making my existing condition worse.

Venlafaxine is an anti-depressant, and can be causing your symptoms, sounds like it's a bit too much for you, along with you having some of the side effects of the medication.  Regardless, you need to speak with your cardiologist about this and the impact it may be having on you. Take care...

Why have you been given this medication? Has the doctor explained this to you?

Yes this medication can cause at least some of what you describe. Usually only short term, 2 weeks or so though.
