Humulin ReliOn R is one of several brands of "Regular" (short-acting) insulin, used for a quick consumption of blood sugar with little delay. ReliOn brand insulin wa formerly made by Novo Nordisk, who had been responsible for producing the ReliOn insulins since 2000. [2][3] The ReliOn insulins are still offered in the same types, R, NPH, and 70/30 mix, but they are produced by Eli Lilly and branded as Humulin/ReliOn insulins. [4][5][6] Novolin insulins have NOT been discontinued; these insulins are available as Novolin N, Novolin R, and Novolin 70/30. Only the ReliOn/Novolin branded insulins have been phased out.

It consists of zinc insulin crystals dissolved in clear fluid with no additives to alter its action or speed. [7]

Other brands with the same action profile include:

A short-acting, soluble, non-suspended insulin produced from r-DNA/GE/GM, bovine, or porcine sources. From 1921 to the 1930's when PZI was developed, R was the only kind of insulin available.

While both R/neutral and semilente insulins are considered fast-acting, they differ in a few ways. As above, there's no suspension or buffer [17] in R/neutral; it's totally dissolved and soluble, meaning it can safely be used intravenously. [18]

The very small insulin particles in semilente insulin are suspended by zinc. [17] Semilente is cloudy, has an acetate buffer and cannot be used intravenously.

R/Neutral insulin cannot be reliably mixed with Lente or Ultralente insulins. [19][20] Semilente can; the ratio of 3 parts semilente insulin to 7 parts ultralente insulin produces Lente insulin. [17]
