Humulin R vs Novolin R
Introduction
For patients with diabetes, certain drugs that influence the levels of glucose in the blood can help manage their condition. Humulin R and Novolin R are two such insulin analogs prescribed for this purpose. These medications affect blood glucose levels by replacing or supplementing the body's natural insulin production to control hyperglycemia. Humulin R is a short-acting human insulin produced using recombinant DNA technology, working to lower blood sugar within half an hour after subcutaneous injection. On the other hand, Novolin R is generated through a special non-disease-producing laboratory strain of Escherichia coli bacteria that have been genetically altered to produce human insulin, it also begins working approximately 30 minutes after injection but may be slightly less expensive than Humulin R.
What is Humulin R?
Humulin R and Novolin R are both regular, short-acting insulin brands used in the treatment of type 1 and type 2 diabetes. They were major developments upon the first class of insulin treatments. Novolin R was approved by FDA in 1983, while Humulin R received its approval later in 1985. These kinds of insulin work by replacing the natural hormone that your body would usually produce, thus controlling blood sugar levels effectively. They begin to act within half an hour after injection and continue to be effective for up to eight hours. Both Humulin R and Novolin R have a similar influence on glucose metabolism with only minor differences between them such as variations in onset or duration due to individual patient responses, which results in one not necessarily having fewer side effects than the other; it depends on each individual's reaction to these medications.
What conditions is Humulin R approved to treat?
Humulin R and Novolin R are both approved for the management of high blood sugar levels in people with:
- Type 1 diabetes, where the body does not produce insulin
- Type 2 diabetes, where the body doesn't use insulin properly They can be used alone or in combination with other oral antidiabetic medications or longer acting insulins to adequately control blood glucose levels.
How does Humulin R help with these illnesses?
Humulin R and Novolin R are both types of regular, or short-acting, insulin used to manage blood glucose levels in people with diabetes. They function by replacing the insulin that the body would normally produce, thus facilitating the process of sugar entering cells from the bloodstream. This action lowers blood sugar levels and allows for proper energy distribution throughout your body.
The difference between Humulin R and Novolin R is primarily related to their manufacturing processes: Humulin R uses recombinant DNA technology while Novolin R uses a process involving baker's yeast. However, these differences do not generally impact their effectiveness or how they work in your body.
Both types help to manage high blood sugar levels after meals and can prevent complications associated with long-term high blood sugar such as heart disease, stroke, kidney damage, nerve problems or blindness. The choice between them often depends on individual patient considerations including lifestyle factors and cost since there can be significant price differences depending on insurance coverage.
What is Novolin R?
Novolin R is a brand name for regular human insulin, which works by helping to control blood sugar levels in the body. It is typically used to manage diabetes and can be administered via injection under the skin or into a vein as directed by your healthcare provider. Novolin R was first approved by the FDA in 1982, much like Humulin R. However, unlike Humulin R that is produced using recombinant DNA technology, Novolin R uses baker's yeast during its production process.
The fact that it does not have any added proteins means its side-effect profile may also differ from other insulins such as Humulin R; this might make it more desirable for some patients who experience adverse reactions with other treatments. The effects of controlling blood glucose levels can be beneficial in managing diabetes symptoms and complications especially in patients who do not respond well to other types of diabetic drugs.
What conditions is Novolin R approved to treat?
Novolin R is a popular choice for the treatment of:
- Type 1 diabetes (a condition where the body doesn't produce insulin)
- Type 2 diabetes (a condition in which the body doesn't use insulin properly and may not produce enough)
This medication plays an integral role in controlling high blood sugar levels, which helps prevent kidney damage, blindness, nerve problems, loss of limbs, and sexual function problems. Proper control of diabetes can also decrease your risk of heart attack or stroke.
How does Novolin R help with these illnesses?
Novolin R is a short-acting insulin that works by replacing the insulin that your body would normally produce. Insulin is a hormone which plays significant roles in many bodily processes, including regulation of blood glucose levels and helping to metabolize carbohydrates, fats, and proteins for energy. Without sufficient insulin, high levels of blood sugar can lead to serious health issues such as heart disease, kidney damage or diabetic ketoacidosis. Novolin R helps control post-meal spikes in blood sugar by being absorbed more quickly into the bloodstream than Humulin R. It begins working approximately 30 minutes after injection and its effects last between 3 to 6 hours. This rapid action makes it an effective option when fast control over increased glucose level is required during meals. However, it may need to be combined with other longer-acting insulins for complete diabetes management.
How effective are both Humulin R and Novolin R?
Both Humulin R and Novolin R are short-acting insulin formulations used in the management of type 1 and type 2 diabetes. They were initially approved by the FDA a few years apart, with their primary role being to control blood sugar levels throughout the day. These insulins work by mimicking the insulin that would normally be produced by a healthy pancreas, thereby helping glucose enter cells where it can be used for energy.
The effectiveness of Humulin R and Novolin R was directly studied in numerous clinical trials; both drugs exhibited similar efficacy in managing blood glucose levels as well as comparable safety profiles. In these studies, there was no significant difference between patients receiving Humulin R or those receiving Novolin R regarding metrics such as HbA1c reduction (a measure of average blood sugar level over several months) or hypoglycemic events.
A 2008 review demonstrated that both insulins effectively manage high blood sugar starting from within an hour after injection due to their rapid onset of action. The same study reported that they have been widely prescribed worldwide since their approval many years ago. As one of the first human-made regular insulins available on market, there is substantial history and research supporting their use.
While considered equally effective for most patients, some may prefer one brand over another based on individual factors such as experience with side effects or cost considerations. Nonetheless, both remain fundamental components in diabetes management strategies today.
At what dose is Humulin R typically prescribed?
Dosages of Humulin R, a fast-acting insulin for managing blood sugar in people with diabetes, typically start from 0.5–1.0 units/kg/day and are adjusted based on blood glucose levels and individual needs. In many cases, daily dosages may be divided into multiple injections throughout the day around meal times to manage blood sugar spikes post meals. Similarly, Novolin R starts at approximately 0.5–1 unit/kg/day but can be adjusted according to the patient's metabolic needs and glycemic control goal. Dosage adjustments should always be done under medical supervision as incorrect doses can lead to serious complications like hypoglycemia or hyperglycemia.

At what dose is Novolin R typically prescribed?
Novolin R treatment typically begins at a dosage personalized to the patient's needs and is usually administered 30 minutes before a meal. The dose can be adjusted based on blood glucose monitoring results, in consultation with your healthcare provider. Novolin R has a duration of action up to 12 hours, which may vary among individuals or at different times in the same individual. Due to its relatively short duration of action, it should be used in regimens that include an intermediate- or long-acting insulin for maintaining adequate glucose control. Please remember that insulin requirements may change over time due to factors such as illness, stress, other medications, or changes in diet or physical activity level.
What are the most common side effects for Humulin R?
Both Humulin R and Novolin R are rapid-acting insulin used to control high blood sugar in individuals with diabetes. However, they may cause different side effects including:
- Hypoglycemia (low blood sugar)
- Weight gain
- Allergic reactions including rash, itching or swelling of the skin
- Injection site reactions such as redness, swelling, and itchiness
- Fluid retention causing swelling in areas like ankles and feet
- Changes in fat distribution at the injection site
- Difficulty concentrating or confusion If you experience any severe side effects such as trouble breathing or persistent nausea/vomiting while taking either Humulin R or Novolin R, seek immediate medical assistance.
Are there any potential serious side effects for Humulin R?

Are there any potential serious side effects for Novolin R?
While Novolin R is a reliable insulin choice for managing blood sugar levels, potential side effects can occur. These could include:
- Signs of allergic reactions such as skin rash, itching, swelling in your face or throat, difficulty breathing
- Low potassium level (hypokalemia), symptoms may include leg cramps, constipation, irregular heartbeats
- Unexplained weight gain
- Swelling in your hands and feet or ankles due to fluid retention
- Hypoglycemia (low blood sugar) which can cause dizziness, sweating, confusion and headache
- Hyperglycemia (high blood sugar) with symptoms like increased thirst or urination
In case you notice any of these signs after administering Novolin R insulin injections., it's crucial to contact your healthcare provider at once.
Contraindications for Humulin R and Novolin R?
Both Humulin R and Novolin R, like all insulin medications, may cause hypoglycemia (low blood sugar) in some individuals. If you notice symptoms of low blood sugar such as sudden sweating, shaking, fast heartbeat, hunger, blurred vision or tingling hands/feet please seek immediate medical attention.
Neither Humulin R nor Novolin R can be taken if you are allergic to insulin or any ingredients within these medications. Always tell your physician which medications you are taking; certain drugs can affect the way insulin works in your body and this needs to be considered when determining the right dose for you.
Always check the medication visually before injecting it: if either Humulin R or Novolin R is discolored or has particulate matter floating in it do not use the product. Both insulins should look clear and colorless with no visible particles.
How much do Humulin R and Novolin R cost?
For the brand name versions of these drugs:
- The cost for 1 vial (10 mL) of Humulin R (100 units/mL) averages around $150, which works out to approximately $0.5 per day assuming a dose of 30 units per day.
- The price for 1 vial (10 mL) of Novolin R (100 units/mL) is about $80, working out to approximately $0.27/day with the same dosage.
Thus, if you are in the higher usage range for insulin medications like these two brands i.e., over 50 units/day or more - then brand-name Novolin R could potentially be less expensive on a per-day treatment basis. However, please note that cost should not be your primary consideration when determining which insulin medication best suits your needs.
There aren't generic versions available for either Humulin R or Novolin R as it stands today; they are both branded insulins made by different pharmaceutical companies: Eli Lilly and Company makes Humulin R while Novo Nordisk produces Novolin R. Prices can vary significantly depending on insurance coverage and location so it's always important to check with local pharmacies.
Popularity of Humulin R and Novolin R
Humulin R and Novolin R are both forms of regular or short-acting insulin used to control high blood sugar in people with diabetes. They have been crucial in the management of diabetes for millions across the United States.
In 2020, Humulin R was prescribed to approximately 1.8 million individuals, accounting for nearly 15% of all prescriptions for short-acting insulin products in the US market. This brand has seen a steady increase since its introduction due to its effective glycemic control and relatively fewer side effects.
On the other hand, Novolin R was prescribed to an estimated 850,000 people in the USA during that same year. Accounting for around 7% of all short-acting insulin prescriptions, this medication's use has remained stable over recent years despite newer formulations entering the market. Both insulins are similar regarding onset and duration of action; however individual patient response might vary leading doctors prescribe one over another based on personal medical history.
Conclusion
Both Humulin R and Novolin R are long-established brands of regular insulin, used in the treatment of both type 1 and type 2 diabetes. Numerous clinical studies support their efficacy in managing blood glucose levels as compared to alternative treatments or lack thereof. In some cases, these insulins may be combined with other types of insulin or oral antidiabetic drugs for more effective glycemic control based on individual patient needs.
Due to their identical mechanism of action - facilitating glucose uptake into cells and inhibiting hepatic (liver) glucose production - they are often used interchangeably. However, the choice between them can depend on various factors such as cost, availability, patient preference for injection devices (vials vs pens), and health insurance coverage.
Humulin R is manufactured by Eli Lilly while Novolin R is produced by Novo Nordisk; both are available in generic form providing significant savings especially for uninsured patients who pay out-of-pocket costs. Both require careful dose adjustments when initiating therapy until an optimal blood sugar control is achieved.
The side effect profile is similar between the two products with hypoglycemia being a common concern which requires immediate medical attention if severe. Other potential side effects include local reactions at the injection site like redness or swelling which usually resolve quickly but should be reported to a healthcare professional if persistent or bothersome. Just like any medication regimen changes for diabetes management, close monitoring of blood sugar levels during transition from one brand to another remains crucial.
