Dostinex/cabergoline at .5mg/wk is a very small amount. It is a small molecule and not a steroid. I don't think that they could see this unless using a specific test... that probably does not exist.
Cabergoline lowers prolactin and also increases dopamine. A good combination. I find that it has an effect that is completely different than Wellbutrin. Wellbutrin seems to act on the whole brain and can create a general state of [over] stimulation. If you try to stop, or forget to take, your Wellbutrin, you do not feel right. Right after getting into .5mg/wk cabergoline, I felt different and second dose got a headache with over stimulation [agitated]. I seemed to understand what was going on [too much dopamine] and I was suddenly not taking wellbutrin or very little some days. I now take 50mg wellbutrin some days.
I conclude that [for me], cabergoline increases dopamine in targeted areas and that wellbutrin is a shot gun. With little to no wellbutrin most days, [maybe zero soon] with the cabergoline, I really feel more like myself and my thought patterns are more natural. Focused instead of what seems to have been an effort to focus a lot of stray mental activity.
I think that cabergoline has some superior actions compared to wellbutrin and may be a very good way to transition out of wellbutrin. Wellbutrin may be creating its own dopamine dependence, almost like the addictive drugs that it helps one stop taking. The dopamine blitz of wellbutrin may have similar actions to other dopaminergic drugs such as the amphetamine family and other addictive drugs.
When cabergoline is used off label to counter the negative sexual effects of SSRIs, much of this effect will be from the dopamine, even though lowering prolactin has obvious benefits. Wellbutrin is also used to this end with SSRIs.
I think that there might be some good results if cabergoline was used as a first line drug to increase dopamine, avoiding wellbutrin. We also do expect to see higher prolactin when dopamine levels are low.
I do think that wellbutrin is a fantastic drug. Some may feel over stimulated, others not. Trazodone is a great sleep aid and has great effects. It does not seem to over stimulate and I interpret that as a more targeted and focused effect. Trazodone and .5mg/wk cabergoline may be a very good combo for some.
