Hi DR, I need to know what is Effexor half-life and detection time. I m extremely well informed on neurotransmitters and hormones, so, consider you talk to someone who will understand your answer thoroughly. This is urgent for me to have an answer. Thank you very much Gpaltrow
Hello, Thanks for choosing Chat Doctor for posting your query. I have gone through your question in detail and I can understand what you are going through. Effexors half-life is only 4 hours. Its primary metabolite, O-desmethylvenlafaxine, has a half-life of 10 hours. Its elimination time is 10-16 hours. Now there are some extended release preparations available which have a higher half life. Hope I am able to answer your concerns. If you have any further query, I would be glad to help you. In future if you wish to contact me directly, or want to know any further details about your query, you can use the below-mentioned link
