About Nigel Simmons
Expertise
I am happy to answer general questions on medicines and hospital care. If possible, please use approved / chemical names rather than brands which are not internationally recognised.
Like all health professionals I am bound by a duty of care which prevents me giving detailed information about medication or treatment of people other than the questioner.
I will endeavour to help wherever possible or point towards more appropriate advice. If however your question crosses too far into patient confidentiality, I hope you will understand why I cannot answer your question.
Consider.. would you want me to discuss your care with a friend or relative without your knowledge?

Expert: Nigel Simmons

Subject: novo-venlafaxine xr
Question
I am experiencing slight changes in my vision with this drug. I have been taking the product for close to a year now, started at 37.5, then 75, now 150 mg. When I have missed a dose in the past (75 mg level) my vision seemed to "skip" or shift rapidly about 1 inch to the right. Its is almost as if you rapidly close one with the other open then switch eyes. Is this normal? Should I be concerned?

Visual disturbances is a common side effect of venlafaxine treatment, and it is most likely to be dose related.
The XR formulation is designed to give a steady blood level of drug over 24 hours, but missing doses would result in a fall in levels and possibly the development of symptoms of withdrawal or ones which you have otherwise adjusted to. So, it may be that you have adjusted to visual changes with venlafaxine, but when you stop it the compensation isn't necessary, so your vision appears distorted.
This is only a working hypothesis (thought process), but I would recommend talking to your doctor about it and obviously doing what you can to avoid missing doses. Bear in mind that a disturbed vision is a risk if you are driving or doing detailed work. Were you to have an accident, there is a possibility that you may invalidate your insurance because you are not in full (visual) control.
I hope this helps.
