Insulin Reaction Overview

Insulin Reaction Overview

An insulin reaction is an excessively low blood sugar level (hypoglycemia), usually lower than 50 mg/dL. Insulin reactions result from an excess of insulin via an injection or an excess of an insulin-stimulating oral hypoglycemic agent, usually in the sulfonylurea class of drugs. Insulin reactions are more common in people with severe diabetes. Hypoglycemia occurs more often when a person is attempting to achieve near normal blood sugar levels.

INSULIN STORAGE AND POTENCY

Insulin from various manufacturers is often made available to patients in an emergency and may be different from a patient's usual insulin. After a disaster, patients in the affected area may not have access to refrigeration.  According to the product labels from all three U.S. insulin manufacturers, it is recommended that insulin be stored in a refrigerator at approximately 35 to 46 degrees F.  Unopened and stored in this manner, these products maintain potency until the expiration date on the package.  However, all of the available insulin products may be left unrefrigerated (between 59 and 86 degrees F) for up to 28 days and still maintain potency.

How does insulin help diabetes?

People with Type 1 diabetes produce inadequate amounts of insulin, so insulin replacement is their key treatment.

Without adequate insulin replacement, people with Type 1 diabetes will see their blood sugar levels rise and the body will start to burn up its fat stores. In a few days this leads to a condition called diabetic acidosis, which is life threatening.

Alternative Devices for Taking Insulin

Many people who take insulin to manage their diabetes inject the insulin with a needle and syringe that delivers insulin just under the skin. Several other devices for taking insulin are available, and new approaches are under development. For more information about insulin, see Medicines for People with Diabetes.
Injection aids are devices that help users give injections with needles and syringes through the use of spring-loaded syringe holders or stabilizing guides. Many of these aids use push-button systems to administer the injection.

Insulin pens can be helpful if you want the convenience of carrying insulin with you in a discreet way. An insulin pen looks like a pen with a cartridge. Some of these devices use replaceable cartridges of insulin; other pen models are totally disposable. A short, fine needle, similar to the needle on an insulin syringe, is on the tip of the pen. Users turn a dial to select the desired dose of insulin and press a plunger on the end to deliver the insulin just under the skin.

Background

Insulin resistance is a state in which a given concentration of insulin produces a less-than-expected biological effect. Insulin resistance has also been arbitrarily defined as the requirement of 200 or more units of insulin per day to attain glycemic control and to prevent ketosis.

The syndromes of insulin resistance actually comprise a broad clinical spectrum, which includes obesity, glucose intolerance, diabetes, and syndrome X, as well as an extreme insulin-resistant state. Many of these disorders are associated with various endocrine, metabolic, and genetic conditions. These syndromes may also be associated with immunological diseases and may exhibit distinct phenotypic characteristics.
