Just spent some time digging around PubMed. Trying to ascertain addiction potential on this one, and if any noteworthy post marketing data has come out. So far just seeing the FDA listed it as a precautionary C-IV.

Are people seeing any efficacy with this med?
Any case reports of abuse?
 
Have tried a few patients on it but nothing that springs to mind in terms of effectiveness that's really impressed me at this stage. I believe the trials found patients who had already been on z-drugs and benzos were less likely respond, so there might be a role for it as an initial intervention. I think early trials also excluded those with substance issues, so any talk on addiction is likely going to be anecdotal only.

Can only get it in 15mg and 20mg strengths, and here it's fairly costly. I haven't heard if it generates any positive sensations like calmness/high etc which would make me more cautious regarding abuse.
 
I've placed patients on it mostly cause it's not a benzo or non-benzo like. I've seen no substance use or anything suggesting it at this point so far. The main drawback is that it's very expensive and insurance might not pay for it.

How effective? Not as much as a benzo or benzo-like med but those are meds we typically want to avoid for patients with chronic insomnia. I do have some patients where it's worked very well. It's also a med where if it doesn't work continuing it for about 1 week may work better than just trying it for 1 night.

The only major problem other than the price and it might not work is that a problem I'm seeing is most of my patient c/o poor sleep are overweight and I have strong reason to believe their insomnia is from OSA but getting a sleep study can be a pain in the butt.

Well good news, maybe the orexin antagonism will promote weight loss.
 
A thing to note about suvorexant is that the FDA approved super low doses that have almost no evidence for efficacy - the 10 mg dose wasn't even tested in Phase III and 5 mg has never been tested, as far as I can tell. The manufacturer thinks 40 mg is a more reasonable dose and wanted that approved, but no dice. The company actually explicitly told the FDA that they thought 10 mg was clinically ineffective. Of course the 40 mg dosage is also associated with suicidal ideation, daytime sleepiness and occasional cataplexy. Also the drug-withdrawal rebound insomnia seems to be pretty awful. So not ideal in so many ways.

The more interesting literature is starting to look at using it for addressing alcohol-induced sleep disruptions and possibly ameliorating cocaine cravings, but that is all still very preliminary.
 
The attraction to this new med is pretty much nothing indicated for long-term insomnia other than Ramelteon and this med are safe with long-term use, and while Ramelteon has some differences with Melatonin I've never seen any strong data showing it's superior to it especially to the degree where it's worth taking at hundreds of dollars a month vs OTC Melatonin that's about $10/month or less.

Before Ramelteon and Suvorexant came out what I used to do was place patients on rotating sleep-med schedules. E.g. 2 weeks Zolpidem, then 2 weeks Trazodone, etc. Of course this was after I had them try sleep-hygiene and other non-prescription med approaches such as Melatonin.

But at more and more time passed by and I gained more knowledge and experience I came to realize many of my patients with insomnia had OSA and that they really needed to treat the OSA with a CPAP. This is something not taught in training that I caught on later. With so many people overweight these days and suffering from insomnia, it's frustrating that sleep studies are so expensive. Then add on top of that often times the sleep doctor doesn't communicate to me at all even after I've send him the umpteenth request for the patient's sleep report with the patient's permission.

Another insomnia factor I learned of later on in melatonin can work better if used for several days straight instead of just in one night. It resets the brain's circadian rhythms. Again not taught in usual training and much better alternative to taking Zolpidem long-term as many are doing these days despite that the data shows doing so isn't helpful and even potentially dangerous.

This.
Patients snores = get Sleep Medicine consult for OSA rule out.

Its not quite as good, but home sleep studies are fairly inexpensive (and insurance rarely fights back on them at present).
