I have taken 1 dose of Effexor (venlafaxine) xr 37.5 mg & had side effect because I'm sesentive to meds, how long till its out of my system?

About 48 - 72 hours: You should not use an extended release form of any drug if you are sensitive to meds. A low dose of an immediate release form of the medication is better. Discuss your options with your doctor. Best wishes! ...Read more

How can I know that my ''effexor XR 75mg'' works effectively? I used it for 6 weeks until now.

Team Talk: The treatment of depression with medication is a team project with you and your M.D. As the team. Often the game plan will include psychotherapy and medication. If a psychiatrist is rx the meds and providing psychotherapy, the progress will be discussed in sessions. If non- M.D. Is doing psychotherapy, there will need to be talk between 3 team members. Sometimes it takes 4-6 weeks for meds to work. ...Read more

Began effexor-xr 9 weeks ago for gad and health anxiety. Up to 112.5 mg today. No effect yet. What is the average dose at which an effect is seen?

Effexor (venlafaxine): It sounds like your doctor is being gradual in titrating your dose. I have seen some effectiveness of Effexor (venlafaxine) around 150mg/day. However, I hope you're not relying completely on Effexor (venlafaxine) to relieve your health anxiety. Psychotherapy is essential also. Best wishes. ...Read more

I was wondering if it is safe to take Remeron (Mirtazapine) and Effexor XR (Venlafaxine ER) six hours apart from each other? E.g. Ven 6pm & Mirt 12am

Caution!: You do not state how come you are taking two different antidepressants - mirtazapine alone taken at bedtime should enable sleep and at gradually increasing doses should take care of the depression. Venlafaxine tends to have stimulating features in many people, perhaps accounting for it. This should be taken early in the day and at proper doses should take care of the depression alone. ...Read more

I'm taking 150 mg of Effexor-XR for GAD. Anxiety & nervousness are listed as common side-effects. Tense now: side-effect (lower dose) or increase it?

However, this dose is generally achieved after a 1-2 week titration period. Best bet is to call the prescribing doctor and tell them what's happening since they know your history. If manageable, try to stick with it for a few more days. Hope that helps! ...Read more

If I'm allergic to Effexor XR (itchy/can't breathe well) can I be put on pristiq (desvenlafaxine)?

Allergy to Effexor (venlafaxine): It is possible but not entirely that you will be allergic to Pristiq (desvenlafaxine) if you are allergic to Effexor (venlafaxine) because the molecules are similar. Although you may be allergic to other compounds in the medication (excipients or extended release formula) it is possible to try and see if you develop the same symptoms.
