What is NPH Insulin, Its Side Effects, Onset Peak Time and Duration?

What is NPH Insulin, Its Side Effects, Onset Peak Time and Duration?

Insulin is a type of hormone which is produced by the pancreas to help our body to properly use the glucose we derive from food we eat. People with diabetes cannot naturally produce enough amounts of insulin or use it properly. This leads to a build up of glucose in the body rather than moving into the cells. High levels of blood sugar can lead to health problems for people with diabetes. However, insulin can be injected under the skin to help people with diabetes reduce the level of blood sugar in their body. NPH insulin is the medication used by patients with diabetes to help manage blood glucose. This type of insulin works by enabling blood glucose to get into the cells so that it can be used for energy by the body. Taken note that insulin NPH is not a cure for diabetes, but helps to control blood sugar levels.

 

What is NPH insulin?

NPH is an acronym for Neutral Protamine Hagedorn. NPH insulin also referred to as isophane insulin, is a type of insulin that is given to patients with diabetes to help control their blood sugar levels. It is taken as an injection and the metabolic effects can be felt within 1 or 2 hours after injection. However, its strongest effect is felt between 6 to 10 hours after injection.

 

Insulin Isophane peak

Insulin NPH is considered to be an intermediate acting insulin, which takes 1 to 3 hours before the injection effects are felt. Isophane insulin peaks between 5 and 8 hours after injection but the effects start to cease after 18 to 24 hours.

 

Dosage

The insulin NPH dosage that your doctor recommends depends on the ability of your pancreas to produce insulin and how well it is used by your body. Your doctor will recommend the right dose, depending on the results obtained after monitoring the values of your blood sugar levels. Other factors like medications used and body weight may affect the dosage your doctor recommends for you. If you have Type 1 diabetes, your doctor may recommend 0.5 to 1 unit/kg/day. It is recommended you take the prescribed units, at least 30 to 45 minutes before having your meal.

 

How to Inject

Insulin isophane is usually injected once or twice a day. Always make sure that you useb this medicine as it is prescribed by your doctor so that you can maximize on its benefit. Dosage adjustment may be required if the brand or species of insulin are changed. You may require a higher dosage of insulin if you are using it concurrently with other medication with hyperglycemic effects or are obese, stressed or pregnant. A lower dosage may be required if you are exercising, under a weight loss program or are using other drugs concurrently that has hypoglycemic effects. You should not use insulin isophane if you have low blood glucose levels or you are allergic to the ingredients used in the medication.
