Veins relatively insensitive - to irritation by irritant drugs at higher concentration in dosage forms.
Suitable vein - It may be difficult to find a suitable vein.
Maybe toxic - Because of the rapid response, toxicity can be a problem with rapid drug administrations, could then give as an infusion, monitoring for toxicity.
Requires trained personnel - Trained personnel are required to give intravenous injections.
Expensive - Sterility, pyrogen testing and larger volume of solvent means greater cost for preparation, transport and storage.
