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.
No. These drugs are not listed as interacting with each other, so using them together should be safe.

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.

OK. Generally venlafaxine is taken in the morning because it can be a bit activating but there's no contraindication to taking it at another time. Remeron and venlafaxine complement each other. Remeron should be taken at night as it is sedating. 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.

On 112.5mg Effexor (venlafaxine) for 6mths. Mood dropped unexp. So upped dose to 150mg. 1mth later mood worse so now on 30mg mirtazapine. What caused mood drop?

Wrong medication. Ask your treating physician about using Zoloft, Lexapro, (escitalopram) or Celexa- certainly more rapid acting: I would also advise psychotherapy with a behavioral counselor ( therpist) using CBT ( cognitive behavioral therapy ). Read more...
Could be many causes. There can be a number of triggers to low mood, including: medical illness, stress, loss, relapse of depression, seasonal changes and even just normal variation. It would be best to talk to your doctor about the possible explanations to see if you need any further medical work-up or if adding other treatment components could be helpful (e.g. psychotherapy).

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...

I've tried sertraline, then citalopram, now on mirtazapine and venlafaxine. Will these drugs ever work? Losing hope.

Add CBT therapy. For decades research has shown that optimal therapy outcomes require therapy - it enhances medication and for some is sufficient alone. The need to learn symptom mgmt skills cannot be met w/out it. Don't lose hope - it is also a major part of successful treatment. In fact, w/out confidence it is unusual for any treatment to be a success. So, find a therapist you trust and work at it! Best! Read more...

Most likely. While federal regulations prohibit me from recommending the use of schedule I medications such as cannabis I can tell you that there is overwhelmingly scant evidence that its consumption with the drugs that you listed would be risky. That said IF you were to consume it any option other than burning it to ingest it would be preferable: i.e. consider an edible, atomized or nebulized form. Read more...
