Tell me something Ian, I once read that taken these two together, is on a high dose of valium, can actually effect how the remeron works?
Possibly, at least indirectly. There is some evidence that increased GABAergic activity inhibits neurogenesis, therefore it has been hypothesized that the increased GABAergic activity induced by benzodiazepines (and alcohol) may have an effect. However, this is by no means certain. For a starter most anxiety patients have impaired benzo-GABA function, yet have atrophied hippocampi too.
This also needs to be weighted against the known deleterious effects of uncontrolled anxiety on neurogenesis. Plus benzodiazepines often help people get past the initial antidepressant side-effects so they can continue taking ADs. ADs can only work if they are taken and, unfortunately, most of those prescribed ADs stop taking them within a week or two, mainly because of side-effects, particularly heightened anxiety.
I know my own doctor wanted me on 30mgs of valium. I refused. Only take .5mg in the afternoon. Get by just fine.
I suspect that you would do just as well without it. 0.5mg is a tiny amount, the equivalent of 0.025mg Xanax or 1/10th the smallest dose tablet. Before Klonopin became available epileptics used to be prescribed 200-400mg of Valium daily.
