Apparently associated with high doses of vitamin B6 - Pyridoxine Hydrochloride.


(Note: MSLT sleep study findings for persons with depression do not demonstrate short sleep latency.)

What is an MSLT sleep study? And what is sleep latency?

Yes, I'm obese. I have an objection to the first entry under Associated Conditions. #1e author thinks that obesity alone can cause somnolence and has created an inadvisable compound entry (no supporting citration so I have to assume it's an opinion). #2 There is more than one type of sleep apnea (see linked material) and even though some obese individuals have sleep apnea, not all do. REMEDY: I have removed this anti-fat biased remark as it is unclear and superfluous. —The preceding unsigned comment was added by FelizAZ (talkcontribs) 04:06, 12 February 2007 (UTC).

"The disorder characterized by the latter condition is most commonly associated with users of prescription hypnotics, such as mirtazapine or zolpidem." What are we talking about here, abusers of, for example, zolpidem, or is this common with zolpidem use when used as directed? This needs to be clarified, as it could confuse people.

Even if taken as directed, hypnotics such as zolpidem can cause daytime drowsiness. Fuzzform 22:39, 4 October 2007 (UTC)

Seroquel & Loxapine[edit]

The "anti-psychotic" major tranquillizer Seroquel has somnolence as a side effect (a.k.a. injury). I'm quite sure the other major tranquillizers used as anti-psychotics do as well. Definitely so for Loxapine. Francesca Allan 00:57, 4 September 2007 (UTC)


In the sleep template at the bottom, Somnolence is listed as a Benign Phenomenon. Doesn't sound entirely benign to me. Wikipedia defining it thus won't keep it from being listed as a detrimental side effect re drugs. So it's misplaced in the Benign Phenomena section, I think.

Information needed[edit]

The article doesn't mention anything about what triggers somnolence or why it occurs. If this is known, then it should be added. (talk) 00:56, 23 February 2009 (UTC)

I agree. The section listing links to Associated Conditions is far longer than all the text describing this condition. I know little about medical issues myself, but someone who knows what they're talking about needs to get in here and fill in some info. We should have at least:
  • Causes/Triggers
  • Effects
  • Incidental vs. chronic
Much more would be welcome, but that would be a good starting point. I came to this page looking for the biological mechanism of drowsiness (not unreasonable considering the depth some other medical articles go to), but some basic info would have been welcome.
