Insulin Mnemonic (Ready, Set, Inject, Love)

Insulin is classified into three categories:

• How quickly they start to act
• When they have maximal effect
• How long they start to act

These three characteristics are called

• Onset
  • Onset refers to the length of time before the insulin gets into the bloodstream and starts the process of lowering blood sugar.

• Peak
  • This refers to a time period in which the insulin in the blood is at its optimum when lowering blood sugar.

• Duration
  • Duration refers to the length of the time from the onset where the insulin you inject into a patient lowers their blood sugar.

Mnemonic For Onset Times 

• READY
• SET
• INJECT
• LOVE

1. Ready- Rapid Acting Insulin

Regular or rapid-acting insulin will start lowering your patient’s blood sugar fifteen minutes after the injection.

Rapid-acting insulin usually peaks in an hour but has a duration that lasts a few hours after the injection.

2. Set- Short-Acting Insulin

This type of insulin will reach your patient’s bloodstream 30 minutes after injection.

It will reach its peak within 2-3 hours and stays effective for a duration of about 3-6 hours.

3. Inject- Intermediate Acting Insulin

Intermediate insulin has an onset of about 1-2 hours, a peak of about 4-6 hours, and a duration of about 12 hours.

4. Love- Long-Acting Insulin

Long-acting insulin has an onset of 1-2 hours.

It has a duration of about 24 hours and a gradual peak throughout the 24 hours due to its slow absorption.

Mnemonic  Duration, Onset, and Peak

1. READY- RAPID-ACTING MNEMONIC

“15 year old wanted to grow up fast, 60-90-year-old grandparents misses his childhood days when he was 3-4 years old.”

• Onset- 15 minutes
• Peak- 60-90 minutes
• Duration-3-4 hours

2. SET- SHORT-ACTING INSULIN MNEMONIC

One of the most heartwarming stories of the last decade occurred in the twenty-fourth state to be admitted in the Union (Missouri), where 36 already short-staffed nurses became pregnant at the same time in one hospital.

Besides being heartwarming, this story from Missouri serves to help you remember 24 (Missouri) and thirty-six, which play a significant role in the short-acting insulin mnemonic.

“Within half a year,  one short-staffed hospital in the twenty-fourth state lost and gained  thirty-six nurses, Congratulations.”

• Onset- 30 minutes to 1 hour
• Peak- 2-4 hours
• Duration- 3-6 hours

3. INJECT- INTERMEDIATE-ACTING INSULIN

“Given 2 options, would you rather do four- four-hour shifts for ten dollars or better yet get that 10 dollars in one sixteen-hour shift.”

• Onset- 2-4 hours
• Peak – 4 hours
• Duration- 10-16 hours

4. MNEMONIC FOR LOVE-LONG ACTING INSULIN

“2 climbers are better than 1 for a mountain that doesn’t seem to have a peak. It might take an entire day (24 hours) “

• Onset -2-4 hours
• Peak- non-existent
• Duration – 24 hours or an entire day

Mnemonic For The Different Types of Insulin

Types of Rapid Acting Insulin

The letters “I” and “N” the word INsulin represent rapid-acting insulin in this mnemonic. The intersection of the letter “I” in both rapId and InsulIn brings these two terms together.

Remember:

• The “N” in iNsulin is for Novolog
• The “L” in insuLin is for HumAlog
• All rapid-acting insulin analogs end with the postfix “log.”

Humalog and Novolog

Humalog and Novolog are brand names for insulin lispro and insulin aspart, respectively. They are both rapid-acting types of insulin. Remember the mnemonic

“15 year old wanted to grow up fast, 60-90-year-old grandparents misses his childhood days when he was 3-4 years old.”

Both Novolog and Humalog have an:

• Onset of 15 minutes
• Peak of 60-90 minutes
• Duration of 3-4 hours

Short-Acting Insulin Mnemonic

The letter “S” in insulin (written vertically) is used as the first word for Short, which represents short-acting insulin.

The “R” in short is also written vertically as “REG,” which represents regular insulin, a type of short-acting insulin.

Regular Insulin

Regular insulin is also known as Novolin. It is a type of short-acting insulin with a high absorption rate that gets to work on the blood faster.

However, to avoid confusion with other types of insulin, use regular instead of Novolin. Remember the mnemonic:

“Within half a year,  one short-staffed hospital in the twenty-fourth state lost and gained  thirty-six nurses, Congratulations.”

This means that regular insulin has a:

• Onset of about half an hour to one hour
• A peak of 2-4 hours
• Duration of 3-6 hours

Types Of Intermediate Acting Insulin

Intermediate-acting insulin is an insulin analog that is between long-acting and short-acting insulin. That’s why in this mnemonic, it takes the letter “U” in insUlIn which is a midpoint in the term.

The letter “U” is shared by both insUlin (written vertically) and HUmulin (written horizontally) to give the first intermediate-acting analog in this formula.

The “N” in both HumuliN written vertically and NPH written horizontally gives us the two types of intermediate-acting insulin.

Humulin and NPH

NPH, which is neutral protamine Hagedorn, is a type of intermediate insulin designed to have a low absorption rate that delays both its duration and onset.

NPH works by the addition of a protein called protamine, which a scientist by the name of Hans Hagedorn discovered reduces the absorption of insulin from the subcutaneous layer into the bloodstream.

Remember the mnemonic:

“Given 2 options, would you rather do four- four-hour shifts for ten dollars or better yet get that 10 dollars in one sixteen-hour shift.”

This shows that Humulin and NPH have an:

• Onset of 2 hours
• A peak of 4-10 hours
• A duration of 10-16 hours

Types of Long-Acting Insulin

The rest of the letters in the term insulin written vertically from the word L downwards represent long-acting insulin.

Remember:

• The “L” in insuLin written vertically is for long
• The “I” in insulIn written vertically is for LevemIr
• The “N” in insuliN written vertically is for LaNtus
• Both Levemir and Lantus, which are long-acting insulin, start with the letter “L.”

Levemir and Lantus

Levemir is a solution of insulin detemir, and Lantus is a solution of insulin glargine. Both are absorbed from the subcutaneous fat layer into the bloodstream over 24 hour period.

Levemir and Lantus don’t have a defined peak. This makes them suitable for blood sugar regulation over long periods.

Remember the mnemonic:

“2 climbers are better than 1 for a mountain that doesn’t seem to have a peak. It might take an entire day (24 hours) ”

This shows that Levemir and Lantus have :

• An onset of about 1-2 hours
• No defined peak
• A duration of 24 hours
