Dayvigo® (lemborexant), Eisai’s dual orexin receptor antagonist, was approved in China in recently. I am wondering if it’s the safest drug we can get on the market?
In the past I tried several other sleep drugs and they don’t work very well on me.
I tried a ‘safe’ pill Ramelteon and it halves my deep sleep duration according to the OURA ring.
I also tried low dose of trazodone and it made me drowsy.

I wrote a post about sleeping drugs.
Benzodiazepines is less effective to me since I got insomnia for 3+ years.
I am trying orexin receptor antagonist these days. Orexin is another neurotransmitter that regulates sleep and generally safe to do something to it.
Bryan Johnson is trying similar drugs too.

Personally I think a good sleeping pill at least should have 3 extra characteristic on top of effectiveness:

  1. moderate drug metabolism rates, likely 8h, to avoid daytime sleepiness
  2. safe for long-term use, no risk of cognitive impairment, since insomnia is not easy to cure. Diphenhydramine is a negative one.
  3. not metabolite by CYP450. Many psychiatric drugs need CYP450 to metabolite, which is one of the major reason why these drugs generally have higher risk of drug durg interaction. CYP450, especially CYA3A4 is really easy to inhibit by drug, supplement or even some food, but many substances need it to metabolite.

Lemborexant does not 100% meet my requirements, but I need to try.

Rika_Qu,

I hope this link will be useful. You should find a table of sleep drugs I created a couple of years ago. Don’t take everything you read in the table as being true because I used ChatGPT to create it.

As a note there are several orexin type sleep drugs. Quviviq has I believe the shortest half-life with possibly less of an extended next day sleepiness effect.

As an insomniac I’ve used things you mentioned and found them basically not useful or intolerable. I’ve tried Quviviq before, but didn’t see great effect. However, I’m trying it again and paying close attention to whether or not I feel rested the next day compared to other sleep aids I’ve tried.

In general, I’ve used diphenhydramine and doxylamine (doxylamine being the more effective one) as mainstays and found both to be useful. But, do they lead to early dementia? It’s a dilemma. As an alternative there is Silenor (6 mg) which I’ve used and found effective. For some, including me, after a few days using Silenore there may be a a next-day sleepiness effect that is irritating. But, getting that restful sleep with Silenor is great when I need it.

I would say yes so far, have been on it since July and it definitely helps you sleep. But my dosage is inconsistent, skip 2 days, take 5 mg, skip 3 days, take another pill, etc. It seems to last longer than what’s suggested in the info packet, for me it feels like it’s in my system for 2-3 days, I feel more sleepy than before for sure.

The issue with the DORA (dual orexin receptor antagonists) is interesting. The two common ones Belsomra (suvorexant) and Dayvigo (lemborexant) both have very long half lives. It looks like at low dose ~6% of individuals report daytime sleepiness and at higher dose ~10%.
These agents are not acting on GABA and also do not worsen sleep architecture, which may be one of the big worries with benzodiazepines and other sleeping medications that primary work on GABA.
Additionally, there is growing data that they may delay tau pathology associated with Alzheimer’s Disease.
There is a trial upcoming I believe actually using it in this context.
Unfortunately it is a controlled substance and an Rx will be necessary as importation is a risk of criminal prosecution. Both of these agents in the U.S. are expensive, but are very cheap in India.

I revisited using some type of Rx sleep aid with my MD. Previously, he gave me some samples of Belsomra which I took one dose of and it gave me waking hallucinations before I fell asleep. This time he prescribed Doxipine to start with 1/2 tab. I found it effective for staying asleep through the night. I do have a concern about potential sexual dysfunction side effects but I don’t plan on taking it every night. It’s an expensive med and not covered by my Medicare plans. I’ve found a gummy equally as effective for sleep but with a slight sluggish effect for a short period after waking. Also, I am reluctant to use it on a constant basis. Gummy: Wyld Elderberry THC/CBN.

Doxepin is in the group of meds I won’t use for sleep as it has potent anticholinergic effects and increases neurocognitive decline as do GABA agents. THC is a challenge - it modifies sleep architecture often times decreasing REM sleep - you need to individually check and it is dose dependent. We now however increasingly are seeing data that THC increases vascular bad outcomes even when ingested. The DORA agents seem like a good choice for some people - but sleep is a challenging area for sure; I just don’t advocate taking things that have known significant worse health outcomes.
