Poisoning can occur through skin absorption, oral ingestion, or inhalation. Symptoms from ingestion, inhalation or absorption of large quantities include flushing, headache, dizziness, mental depression, nausea, vomiting, anesthesia, and coma. Alcohol baths or sponges to soothe a fever can lead to acute poisoning through skin absorption or inhalation. Instead, the Regional Poison Center suggests using tepid water as a sponge bath to fight fever.

Isopropanol doesn't sound like the best thing to be injecting into yourself with. Why not use ethyl alcohol?
This is just some plain bad, or possibly outdated advice/material.
Isopropyl Alcohol, when administered by IV or Inhalation is somewhere between 1.5-2x as toxic as good ol' Ethyl Alcohol. You know, that stuff they sell everywhere for the specific purpose of human consumption (basically--for you hard core alcoholics out there--just don't drink the stuff. The Toxicity goes way up when administered orally for some reason. Something to do with first pass metabolism and/or its metabolites...or something along those lines...I think [I'm no expert here so I really can't tell you for sure]). There are numerous studies which have been done regarding this, and many of the same reasons for why you are curious about it. It is now quite heavily used in the pharmaceutical, foods production, makeup, essential oils preparation, and perfumery industries. And has an insanely high LD50 (the amount for which it would prove fatal for roughly 50% of the population).
Twice as toxic as that vodka you drank last weekend. Actually, probably less considering vodka has other, possibly unfriendly, compounds in it. Oh Noes! Better run away quickly before you accidentally IV 250 ml of 91% IPA!!! lol
Sorry to be kind of a jerk about this but I see so much misinformation on this subject, misinformation that is presented basically as unassailable fact, when in reality it is very easily verifiably false. A quick and simple search should lead you to a near countless number of HIGHLY reputable resources/references (i.e. peer-reviewed medical journals, government studies out of both the US and the UK's NIH, pharmaceutical company funded studies, essential oil and perfumery industry studies, and the list goes on and on).
At the end of the day, using IPA as your solvent for preparation of drugs/pharmaceuticals for IV use (all other things being equal that is) is literally less harmful to your body than the last time you got drunk from ethyl alcohol...because it takes a whole lot more ethyl alcohol to get your drunk on than it takes to dissolve some stubborn pharma product that isn't soluble in much else (easily available at least) besides alcohols (and yes, ethyl alcohol and isopropyl alcohol have very similar properties as solutes).
So, even though the advice about IV use of any kind of benzo (or any pill for that matter...but especially benzos since there isn't really much benefit to it, and yet there is some non-negligible risks associated with doing it) that isn't formulated for IV use is a generally bad idea, if you're going to do so anyway, then a dilute mixture of IPA (you don't need straight out of the bottle concentrations...50/50 IPA/H2O or less will do in most cases...significantly less if you have 5-10% propylene glycol handy (the best general benzo solvent ever found in studies to my knowledge is a Alcohol/Propylene Glycol/H20 mixed-solvent preparation...with H20 being the largest component, surprisingly. Sorry I cannot provide out of memory the best ratios they found. Basically though it's PG the least, then somewhat more of the alcohol--ethyl or IPA--and then the rest water dilution [because alcohol can sting pretty bad going in, and propylene glycol is too thick for medical preferences]). No matter how it is prepared though, SLOW injection has been found time and again to not only reduce any stinging from the alcohol, but also be MUCH easier on the veins.
To summarize my hard reduction advice:
1) Don't attempt to prepare benzo pills made for oral use into injectable solutions
2) If you're going to do so despite this good advice, then use the least harmful solvents you can get your hands on.
3) Inject the solution slowly. The slower the better frankly.
*** IPA/Isopropyl Alcohol/Isopropanol/and all its other name incarnations is BARELY more "toxic" when used IV than Ethyl Alcohol/Grain Alcohol/That Stuff That Gets You Drunk/and all its other name incarnations. ***
Here are just a
very small selection of the near countless highly-reputable sources/citations/references that support my post, and brutally reject the near countless posts by others who talk about the stuff like it could be used in chemical warfare lol.
