FWIW, LD50 dosage is low for intravenous injection, but very high (multiple orders of magnitude higher) for intramuscular injection. The risk is generally not getting enough of a dosage, not too little, unless you somehow manage to hit a vein. The main problem is that, if you're carrying around EpiPens for allergic anaphylaxis, particularly for a child, dealing with syringes and bottles isn't really a practical solution for day-to-day living (and definitely not an option if you're carrying them around for yourself -- hard to carry out delicate medical procedures while being unable to breathe). There are probably a lot of people without access to autoinjectors who have had to suffer the consequences of anaphylactic shock.
