Soluble insulins are the only ones that can be used intravenously. This is fast-acting Humulin S sold in the UK; the "S" in its name stands for "soluble".

Soluble insulins can be injected or used intravenously; the suspended insulins or mixes (cloudy insulins) cannot be used intravenously.[1] These short-acting and fast-acting insulin have nothing added to them to delay their onset, as is the case with suspended insulins.

Soluble insulins are mostly in the fast-acting or short-acting classes, and are used alone (not as part of a mix) as bolus insulin to cover meals or as Corrective insulin for blood glucose "corrections" when one's blood glucose level is too high.
