[|AI|]  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:bit.ly/ Chat Doctor.
