See below: She has to detox first which requires an individualized approach. Afterward-she needs to wait 2 weeks prior to an injection of naltrexone. However, I have a protocol for initiating Naltrexone at small doses after 3-5 days and quickly titrating to a full dose by day 7-10. ...Read more

Does naltrexone interfere with either Effexor (venlafaxine) XR or mirtazapine (avanza)?

Does naltrexone interfere with either Effexor (venlafaxine) XR or mirtazapine (avanza)?

No: Naltrexone is a very simple molecule that does not have complex metabolism in the liver, and does not have any known significant drug interactions, except with other opiate drugs, where it blocks their effects, and in people who are dependent on other opiates, can precipitate severe and potentially life-threatening withdrawal. You should make sure the prescriber knows you are on naltrexone. ...Read more

Is it ok to start naltrexone and ativan during detox from alcohol while already taking Effexor (venlafaxine) for depression?

Is it ok to start naltrexone and ativan during detox from alcohol while already taking Effexor (venlafaxine) for depression?

Maybe: Are you getting all these meds from one provider? They are all psychoactive but are different chemicals and have different uses. Naltrexone is for narcotic addiction, whereas Ativan is for anxiety and Effexor (venlafaxine) for depression. With guidance of a doctor, you can navigate all of them together, but require monitoring response to this cocktail. ...Read more

I've been on 30mg mirtazapine for just over a week (switched from 150mg effexor). Have increased anxiety as a side effect. When will this go away?

I've been on 30mg mirtazapine for just over a week (switched from 150mg effexor). Have increased anxiety as a side effect. When will this go away?

Depression: can improve in a week. Anxiety may take a bit longer. Remeron is one of the best antidepressants for refractory depression. It takes a while to get settled in if you discontinuing Effexor (venlafaxine). Some of the action of Remeron is thought to be due to activity at two of the endogenous opiate receptors. Remeron is used as a treatment for anxiety as well as depression. ...Read more

Was on Mirtazapine for 1 1/2 years, switched to Effexor (venlafaxine) 4 days ago and it makes me sick/spacey. What would be a good antidepressant thats not an SSRI?

There are plenty: You might be between a rock and a hard place, pharmacologically speaking. You are in Mirtazepine withdrawal, and experiencing initial serotonergic side effects from the effexor (venlafaxine). There are other options, but if your doctor preferred effexor (venlafaxine), I advise to taper off the Mirtazepine for a few more days and obtain regular, non XR effexor (venlafaxine) a titrate after mirtazepine taper from 1/2 37.5 mg. ...Read more

Been on Suboxone for yrs. Took Effexor (venlafaxine) and it put me into severe withdrawal. Will remeron do the same?

Been on Suboxone for yrs. Took Effexor (venlafaxine) and it put me into severe withdrawal. Will remeron do the same?

Effexor (venlafaxine): effexor (venlafaxine) wouldn't cause withdrawal. you probably just had side effects. its notorious for being difficult to start and stop. remeron is not anything like effexor (venlafaxine) but it will help with sleep and appetite. also, what about tapering the suboxone? shouldn't have to be on it for "years." ...Read more

I have been out of Klonopin for 24 hours, Effexor (venlafaxine) for 48 hours, and Remeron for 48 hours.  I am working on getting them filled.  Should I be concerned?  What should I do?

Difficult Situation: You're likely going to have withdrawal symptoms. I would see the doctor who prescribed those medicines to get you restarted on those medicines. If unavailable the emergency room would be an appropriate place to consider. Good luck. ...Read more
