NPH insulin
NPH insulin
NPH insulin, also known as isophane insulin, is an intermediate–acting insulin given to help control blood sugar levels in people with diabetes. It is used by injection under the skin once to twice a day. Onset of effects is typically in 90 minutes and they last for 24 hours. Versions are available tha…
How do you administer NPH insulin?
NPH insulin is administered subcutaneously into the layer of fat under your skin using a pen or syringe into your abdomen, arms, or thigh. Many types of insulin can treat diabetes, and your doctor can help you decide which type is best for you.
What is NPH insulin and how does it work?
What Is NPH Insulin? Neutral Protamine Hagedorn (NPH) also known as Isophane insulin is used to improve the blood sugar control in adults and children with diabetes. It’s an intermediate-acting insulin that starts to work within 2-4 hours after injection. The insulin peaks in 4-12 hours and works for 12-18 hours.
When should I increase my N/NPH?
For example, if you are always giving rapid-acting insulin at supper to correct high blood glucose, then you may need to fix “the problem” by increasing the morning N/NPH. By How Much Should I Adjust? The amount that you change the dose depends on how much insulin is currently being given.
What is the peak time for NPH insulin?
NPH Insulin peak occurs at midnight when the body does not require as much insulin and may cause nocturnal hypoglycemia. Fasting hyperglycemia: Morning blood glucose can be high in patients who take NPH insulin in the evening.
How do you titrate NPH insulin?
Start basal insulin 10 units or 0.1-0.2 units/kg daily or divided BID. Titrate dose based on Fasting Plasma Glucose (FPG). Increase by 2-4 units or 10-15% every 3-4 days until FPG within target range, generally 80-130mg/dL (individualize).
Do you use sliding scale for NPH?
Common sliding scale regimens: Long-acting insulin (glargine/detemir or NPH), once or twice a day with short acting insulin (aspart, glulisine, lispro, Regular) before meals and at bedtime.
How do you calculate NPH?
Current bedtime NPH dose is 30 units. 0.80 X 30 = 24 units. 2/3 of 24 = 16 units in the morning....Step 3 - Determine insulin adjustment.Blood sugar average (fasting and predinner) over 3 daysAdjustment to total daily NPH dose120 - 139add 2 units100 - 119add 1 unit80 - 99no change60 - 79subtract 2 units4 more rows
How do you adjust insulin therapy?
Adjust insulin dose prior to the elevated blood glucose level as follows: • If the blood glucose is elevated lunch and tea, increase the breakfast insulin dose. If the blood glucose is elevated before bed and before breakfast, increase the teatime insulin dose.
What is the peak time for NPH insulin?
NPH Human Insulin which has an onset of insulin effect of 1 to 2 hours, a peak effect of 4 to 6 hours, and duration of action of more than 12 hours.
Is NPH insulin intermediate or long acting?
No, NPH (Humulin N, Novolin N) insulin is considered an intermediate-acting insulin. NPH insulin has a longer duration of action than the rapid-acting insulins (Novolog, Apidra, Humalog) and the short-acting insulins (Humulin R, Novolin R).
How Much Will 10 units of insulin drop blood sugar?
Theoretically, to reduce 400 mg/dL blood sugar to about 100 mg/dL, you would need at least 10 units of insulin.
How do I calculate how much insulin to take?
For short-acting insulin, use the “1800 rule.” This tells you how much your blood sugar will drop for each unit of short-acting insulin. For example, if you take 30 units of short-acting insulin daily, divide 1800 by 30.
How much glucose does 1 unit of insulin reduce?
Generally, to correct a high blood sugar, one unit of insulin is needed to drop the blood glucose by 50 mg/dl. This drop in blood sugar can range from 30-100 mg/dl or more, depending on individual insulin sensitivities, and other circumstances.
When do you give insulin correction?
You can give a correction dose whenever you find a blood glucose level above target before a meal and above 9mmol/L 2hours after a meal. Always check your blood glucose level 2hours after taking a correction dose. If after 2 hours the blood glucose remains above target you can repeat the correction dose.
What is the sliding scale for insulin?
A sliding scale varies the dose of insulin based on blood glucose level. The higher your blood glucose the more insulin you take. The Sliding Scale method is more precise than fixed dose insulin in that it takes account of the fact that people's blood glucose is not always in the normal range before meals.
Can NPH be given alone?
Single Pre-Breakfast Injection of NPH Insulin If a single morning injection of NPH is used, near-euglycemia is seldom achieved. This approach requires one injection of NPH to control both the pre-supper glucose concentration and the next morning's fasting glucose value.
Who should use a sliding scale for insulin?
Who is sliding scale insulin therapy for? People with type 1 and type 2 diabetes may use sliding scale insulin therapy. You may also use alternative insulin management methods, like fixed scale insulin therapy where you take a fixed amount of insulin before every meal.
When should sliding scale insulin be given?
Sliding-scale insulin therapy (SSI) In the sliding-scale method, the dose is based on your blood sugar level just before your meal. The higher your blood sugar, the more insulin you take. SSI therapy has been around since the 1930s.
What type of insulin is used for sliding scale?
The types of insulin used for sliding scale therapy include: Long-acting insulin (glargine/detemir or neutral protamine Hagedorn) Short-acting or rapid-acting insulin (aspart, glulisine, lispro, and regular) Premixed insulin (a combination of long-acting and short-acting insulin)
Is Sliding scale insulin recommended?
The American Diabetes Association (ADA) warn that using only sliding scale insulin for treatment is ineffective for most people. It can increase the risk of both high and low blood sugar and of complications if the person needs surgery. Most doctors advise against using this approach.
How is NPH insulin obtained?
The intermediate-acting NPH insulin is obtained from the precipitation of recombinant synthesized human insulin with zinc in the presence of protamine, a basic polyarginine peptide. This process occurs at a neutral pH in an insulin and protamine ratio of 5: 1. This formulation method gives NPH the property of protraction, i.e., slow release of insulin from the precipitated insulin present at the injection site after subcutaneous injection. [1][2][3][4][5] After injecting the protein-insulin complex, the solvent from NPH insulin suspension diffuses into the subcutaneous tissue. These insulin crystals are stacked up like a heap at the injection depot and dissolve gradually, leading to the protracted action of NPH.
Why is frequent glucose monitoring required in children on NPH insulin?
Frequent glucose monitoring is required in children on NPH insulin because of the greatly varying dose need and marked changes in insulin requirements during the growth period of children. [6]

When does NPH peak?
Nocturnal hypoglycemia: The patient is given NPH insulin in the evening. NPH Insulin peak occurs at midnight when the body does not require as much insulin and may cause nocturnal hypoglycemia.
Why is it so difficult to get glycosylated hemoglobin A1C?
It is often difficult to obtain the target glycosylated hemoglobin A1c due to its variable absorption and rapid peak.[10] Also, breakfast injection may not provide coverage till the evening dose, and likewise, the evening dose may not meet the insulin requirement until morning.

How to wash your hands before injecting insulin?
Wash your hands with soap and water before injecting yourself with insulin.
What is NPH made of?
NPH insulin is made from synthetic insulin that’s grown in bacteria or yeasts in a lab. Zinc and a protein extracted from fish (called protamine) are added to slow its absorption in the body.
How long does it take for insulin to peak?
Neutral protamine Hagedorn (NPH) insulin (named after the scientist Hans Christian Hagedorn who invented it) peaks in about 6 to 8 hours, with a duration of up to 12 hours. This type of insulin is generally used to help regulate blood sugar levels between meals and overnight.
How long does NPH last?
NPH insulin can last for up to 12 hours and is typically injected once or twice per day. It can last longer than 12 hours in people with certain medical conditions like kidney failure.
Why can't you share insulin syringes?
It’s critical to never share insulin syringes, pens, or pumps with other people due to the risk of spreading blood diseases like HIV and hepatitis.
Does NPH cause low blood sugar?
NPH insulin has a slightly higher risk of causing low blood sugar than other types of insulin. Severe low blood sugar can cause symptoms like seizures, loss of consciousness, or death.
