When comparing Novolin R versus Novolog Insulin, you may notice a number of similarities and differences.
What is Novolin R?
First, Novolin R is chemically very similar to native human insulin, as both are produced by the bacteria Saccharomyces cerevisiae. Novolin R is a rapid-acting insulin agent and is usually delivered via subcutaneous injection, but it can be delivered intravenously or in an insulin pump.
Using Novolin R
Its lower blood sugar levels by increasing sugar uptake by fat and muscle cells and lowering the production of sugar by the liver. This effect is be expected to occur within 30 minutes of administration. This effect can last for about one and a half hours to three and a half hours and completely ends after eight hours for most people. With this said, you cannot miss your meals after you have taken your insulin shot. If you do, you may undergo a condition called hypoglycemia, which where your blood sugar levels get dangerously low.
What is Novolog?
Novolog insulin, on the other hand, is a rapid-acting insulin analog. In all other characteristics, it is very similar to Novolin R except that its structure differs slightly from regular human insulin.
However, its mechanism of action remains the same, and it is able to exert its effects within one to three hours and can last for about three to five hours, though this time range can vary among individuals.
In a six-month study comparing both Novolin R and Novolog insulin in patients with type 1 diabetes, their efficacy was reported to be about the same. Even the reported rate for the occurrence for hypoglycemia occurring was also similar in both study groups. Hypoglycemia is a can cause symptoms such as tremors, fatigue, dizziness, blurry vision, and hunger. If you do experience any of these, do not wait for a proper meal; immediately seek sugary drinks or snacks before seeking help from a medical professional.
