Mirtazapine and diazepam?

[janebug]

Hey guys. I take 30mg of mirtazapine daily for my anxiety and depression, prior to this I was on sertraline but it didn't help my insomnia... the joys. Anyways, when I was anxious about certain big events on sertraline my doctor would kindly prescribe me some Valium, but now he won't as he said it's not safe with mirtazapine. I don't want to change my doctor and I respect his decision and his opinion, so, does anyone know any medication that will work in the same way but doesn't have an "adverse" effect on mirtazapine?

Thank you in advance x

I was on diazepam at the same time as Mirtazipine. Maybe the doc just wants you off the diazepam?

Was sertraline effective? If so, it might have been better to stay with it and add something for the insomnia. Small doses of immediate-release trazodone (Desyrel) has become the defacto treatment for SSRI induced insomnia (the slow release Oleptro version is a pretty good antidepressant, btw, with few of the typical antidepressant side-effects which really bug people such as their impact on the libido).

You could try increasing the mirtazapine. It is mostly just a powerful antihistamine so sedation is what it does best.

You could try also try the afore mentioned trazodone (Desyrel), but I suspect your doctor would freak at the mere thought because his drug interaction check will probably, incorrectly, highlight a potential for serotonin syndrome.

Unfortunately, much of the medical literature on the syndrome is wrong. Not my words, but that of arguably the leading authority on the subject, Dr Ken Gillman (he calls it serotonin toxicity). To quote:

Even now, in 2016, more than a decade after key research and reviews that demonstrated the essentials of the interactions relevant to serotonin toxicity, there remains a great deal of misinformation and misunderstanding both in medical and non-medical texts.

...Such lack of knowledge and misunderstanding are reflected in advice and warnings concerning ST issued by ‘official’ agencies such as the World Health Organisation (WHO), the American FDA, the UK MHRA, Health Canada and the Australian TGA: their comments and advice have frequently been incorrect and misinformed.

Neither drug is a serotonin reuptake inhibitor, or a serotonin releaser so serotonin syndrome is simply not possible.

That's my thinking.

Sertraline has a Minor interaction with Diazepam whereas Mirtazipine has a Moderate. It's not much of an interaction since it's worded similar to the ones alcohol carries when on these antidepressants. .

A GP in the UK won't be allowed to apply an adjunct like that so they would need to refer to a psychiatrist. That is where it can be tricky, they can be hard to access.

Trazodone is licenses for anxiety or depression (depression where sedation is required). It's not a mainstream one here but GP's do prescribe it for insomnia, it's mixing it that will be the issue for them.

According to Mirt uses on here, it's sedating at lower doses but activating at higher ones. That could be relevant to how it is dosed in the OP's case?

I expect the interaction would simply be due to the sedative effects of both medications.

Personally Mirt really did not help my anxiety much and even that effect didn't last more than a couple of months.

Hopefully the OP will see some benefits, especially with sleep. Didn't help me sleep at all but a friend swears by it.

Yep, that's exactly what the interaction says really.

It's a pretty generic warning though seen on many interactions so I always read the pro section too as it reveal something more specific than the consumer one. Nothing really added in this case though.

Yeah, I am on mirt for my depression mostly - it doesn't help my anxiety but when my depression isn't under control neither am I. I have managed to explain to my doctor what I need the valium for and he has agreed in this instance it is okay.

He basically explain what you both did about the reaction and it basically will make me very tired - but as I want it to go to the dentist I said I was more than happy to have a little nap!

Thank you both for replying in my hours of need. Hope you are both well.

Sertraline has a Minor interaction with Diazepam

But diazepam has a major interaction with sertraline which isn't reflected in the interaction literature, benzodiazepines significantly reduce the effectiveness of antidepressants by blocking hippocampal neurogenesis which is what produces their therapeutic response (see: Stefovska VG, 2008; Wu X, 2009; Sun Y, 2013; Nochi R, 2013; Boldrini M, 2014).

In light of these studies benzodiazepines use should probably be limited to a couple of weeks when first taking antidepressants as they often increase anxiety levels initially, for a while after antidepressant dose increases for the same reason and thereafter for very occasional breakthrough anxiety. If an antidepressant isn't adequately controlling anxiety on its own even at the maximum recommended dose then switching to another which might be more effective should be considered ahead of supplementing it with a benzodiazepine.

Alternatively, adding Buspar (buspirone) may also work as it has a proven track record for boosting the effectiveness of serotonergic antidepressants (and reducing some of their side-effects).

I'm only going off the drugs database on Drugs.com. Why isn't that interaction in drug interaction literature? Is it approved? Not all studies translate to accepted guidelines.

Buspirone is only licensed in the UK for short term use as it lacks evidence beyond that. Some psychiatrists use it though in longer term care but it's not something a GP is advises to do and they likely will be against taking it on themselves to "off label" it.

I've taken mirtazapine with diazepam - a long time in the past, but it was okay. Both have some sedating potential, so you really need to first try them out together when you are at home with some free time. It's also useful to have a friend or partner around. Everyone reacts somewhat differently, so you need to know specifically how it affects you.
