Phenylephrine must be totally useless since pseudoephedrine barely does anything in my experience!
It's not super effective on me either, except for triggering crippling anxiety, but remember that we are outliers, and it's a very effective medication for most folks.

#72The lack of availability of proper pseudoephedrine in USA led to situation where there are papers describing how to turn methamphetamine into pseudoephedrine, not the other way around. With explanation in abstract that its easier to buy meth than pseudoephedrine.
> With explanation in abstract that its easier to buy meth than pseudoephedrine. People may laugh at this, as they should since it is an absurd situation, but this isn't entirely wrong. Neither my wife or I drive and during the pandemic she gave up her license after getting an appointment at the DOL was difficult. Both of us carry US passport cards as our ID. This has resulted in several situations where we've been t…

#73It might not do much if taken orally, but a phenylephrine nasal spray can be pretty powerful.
Also, this is mostly for comfort. There is no really reason to go back to pseudo-effedrive and risk side-effect (high-blood pressure etc.). Also people value their comfort a lot, they are not so good with assessing risks. Apparently that is the reasoning to continue selling phenylephrine because people want to get something even if it is not distinguishable from placebo.

#74The article comes so close to explaining a way to make it work, likely due to his hesitancy to recommend exceeding the recommended dose: > Why is oral phenylephrine so useless? It is extensively metabolized, starting in the gut wall. You can find a bioavailability figure of 38% in the literature, but that appears to be the most optimistic number possible, and you can also find studies that show 1% or less. Overall, t…
Do we have a study showing these (second dose within 30 minutes or paracetamol + phenylephrine) performing better than placebo?
Note that Figure 3 also mentions the Tylenol combination effect and even shows how 10mg Phenylephrine + Tylenol performs somewhere between 10mg and 45mg of phenylephrine.
The article author just cherry-picked the one study where phenylephrine performed the worst. Cherry-picking a single study to support a conclusion and ignoring meta-analyses would normally get someone torn apart in the HN comments but apparently everyone loves pseudoephedrine so it gets a pass.

#76My drug of choice for colds is NyQuil. It's always been great for opening up my nasal passages enough to let me breathe easily and then knocking me the fuck out so I could sleep off most of the cold. I remember several years ago when all of a sudden NyQuil stopped doing anything useful. I had no idea why but I directly observed that it was like it had been replaced with a non-functioning placebo. Only a couple years…

Why not get a non-motorist ID card? Every US state has these; here's Washington's: https://www.dol.wa.gov/driverslicense/gettingidcard.html

Are chemistry papers describing the synthesis of methamphetamine illegal?

Pseudoephedrine is still available -behind the counter-. You literally just have to ask the pharmacist for it. Let’s not turn grad students having a laugh into an actual statement on public policy.

But why get one? A passport/passport card is a _better_ ID document in almost every way. State non-motorist IDs should really cease to exist and we should increase access to passport cards
