What is the difference between Humalog and Humalog 75/25?
Humalog 75/25 means that 75% of the mixture is long-acting insulin (same insulin except it has protamine added to make it act over an extended period of time), and 25% is short-acting. Mixtures like this help keep tighter control of blood sugars because it sort of covers all bases – the quick coverage for your next meal (if you take it right before you eat) and the longer, steadier coverage to last all day.
