Insulins like Humalog and Novolog are necessary to regulate blood sugar levels in those with diabetes. But what\u2019s the difference between these insulin products?<\/p>\n<p>Humalog and Novolog are rapid-acting insulins that work quickly and last for a short duration compared to other insulins. They can be administered before a meal to control blood glucose levels or continuously throughout the day with an insulin pump. Insulin works by increasing the uptake of sugar into the body\u2019s cells for energy. Sugar (glucose) is vital for energy production and overall bodily functions.<\/p>\n<p>Humalog and Novolog may work in similar ways. But they are not interchangeable. Meaning, one can\u2019t be replaced for the other. This is because they have some differences in how they\u2019re prescribed and used.<\/p>\n<h2 id=\"drug-overview-differences\">What are the main differences between Humalog and Novolog?<\/h2>\n<p>Humalog is a rapid-acting insulin analog that was FDA-approved in 1996. It\u2019s identical to human insulin with a similar chemical structure. Humalog, also known by its generic name <a href=\"https:\/\/www.singlecare.com\/prescription\/insulin-lispro\">insulin lispro<\/a>, is available as a solution for injection under the skin (subcutaneous).<\/p>\n<p>Humalog insulin comes in 10 mL and 3 mL multi-dose vials as well as 3 mL cartridges and pre-filled pens (Humalog KwikPen, Humalog Tempo Pen, Humalog Junior KwikPen). All formulations of Humalog contain 100 units\/mL (U-100) of insulin except for Humalog KwikPen, which also comes in a 200 units\/mL (U-200) version.<\/p>\n<p><a href=\"https:\/\/www.singlecare.com\/prescription\/novolog\">Novolog<\/a> is a rapid-acting insulin analog known by its generic name insulin aspart. It\u2019s chemically similar to regular human insulin except it has aspartic acid instead of a proline amino acid in part of its DNA structure. Novolog was FDA approved in 2000.<\/p>\n<p>Like Humalog, Novolog is available as a 10 mL multi-dose vial for patients or providers to draw up with their own syringe. Novolog also comes in a 3 mL cartridge (PenFill cartridges) and pre-filled pens (Novolog FlexPen, Novolog FlexTouch). These formulations contain 100 units\/mL of insulin aspart.<\/p>\n<table class=\"singlecare-table\">\n<thead>\n<tr>\n<th><span class=\"title\">Main differences between Humalog and Novolog<\/span><\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr class=\"header-row\">\n<td width=\"208\"><\/td>\n<td width=\"208\"><strong>Humalog<\/strong><\/td>\n<td width=\"208\"><strong>Novolog<\/strong><\/td>\n<\/tr>\n<tr>\n<td width=\"208\"><strong>Drug class<\/strong><\/td>\n<td width=\"208\">Insulin<\/td>\n<td width=\"208\">Insulin<\/td>\n<\/tr>\n<tr>\n<td width=\"208\"><strong>Brand\/generic status<\/strong><\/td>\n<td width=\"208\">Brand and generic version available<\/td>\n<td width=\"208\">Brand and generic version available<\/td>\n<\/tr>\n<tr>\n<td width=\"208\"><strong>What is the generic name?<\/strong><\/td>\n<td width=\"208\">Insulin lispro injection<\/td>\n<td width=\"208\">Insulin aspart injection<\/td>\n<\/tr>\n<tr>\n<td width=\"208\"><strong>What form(s) does the drug come in?<\/strong><\/td>\n<td width=\"208\">Solution for subcutaneous injection<\/td>\n<td width=\"208\">Solution for subcutaneous injection<\/td>\n<\/tr>\n<tr>\n<td width=\"208\"><strong>What is the standard dosage?<\/strong><\/td>\n<td colspan=\"2\" width=\"416\">Insulin doses are highly variable and should be determined based on a person\u2019s condition, diet, and lifestyle.

These rapid-acting insulins are approved to treat those with Type 1 or Type 2 diabetes.<\/p>\n<p>Humalog and Novolog are also used off-label to treat gestational diabetes, or diabetes that occurs in pregnant women. Women who have risk factors for diabetes are more likely to experience <a href=\"https:\/\/www.diabetes.org\/diabetes\/gestational-diabetes\" target=\"_blank\" rel=\"noopener noreferrer nofollow\">gestational diabetes<\/a> during pregnancy. Insulins like Humalog and Novolog are also used to treat diabetic ketoacidosis, a serious complication that can occur from <a href=\"https:\/\/www.singlecare.com\/blog\/what-are-ketones\/\">high ketone levels<\/a> in those with Type 1 diabetes\u2014and, rarely, with Type 2 diabetes.<\/p>\n<table class=\"singlecare-table\">\n<tbody>\n<tr class=\"header-row\">\n<td width=\"208\"><strong>Condition<\/strong><\/td>\n<td width=\"208\"><strong>Humalog<\/strong><\/td>\n<td width=\"208\"><strong>Novolog<\/strong><\/td>\n<\/tr>\n<tr>\n<td width=\"208\">Type 1 diabetes<\/td>\n<td width=\"208\">Yes<\/td>\n<td width=\"208\">Yes<\/td>\n<\/tr>\n<tr>\n<td width=\"208\">Type 2 diabetes<\/td>\n<td width=\"208\">Yes<\/td>\n<td width=\"208\">Yes<\/td>\n<\/tr>\n<tr>\n<td width=\"208\">Gestational diabetes<\/td>\n<td width=\"208\">Off-label<\/td>\n<td width=\"208\">Off-label<\/td>\n<\/tr>\n<tr>\n<td width=\"208\">Diabetic ketoacidosis<\/td>\n<td width=\"208\">Off-label<\/td>\n<td width=\"208\">Off-label<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2 id=\"efficacy\">Is Humalog or Novolog more effective?<\/h2>\n<p>Humalog and Novolog provide fast-acting effects when administered correctly. Insulin should be given as an injection in the abdominal area, thighs, upper arms, or buttocks. Both Humalog and Novolog are equally effective for lowering blood sugar levels.<\/p>\n<p>Although both insulins work quickly, Novolog works slightly faster than Humalog. Novolog can be injected within five to 10 minutes before eating a meal whereas Humalog should be injected within 15 minutes before a meal.<\/p>\n<p>Compared to other types of insulin, rapid-acting insulins may be better options when used for controlling glucose before or after a meal. In a meta-analysis from <a href=\"https:\/\/www.diabetes.org\/diabetes\/gestational-diabetes\" target=\"_blank\" rel=\"noopener noreferrer\">Diabetes Therapy<\/a>, researchers found that rapid-acting insulin was more effective as a mealtime insulin for Type 1 diabetes compared to regular insulin. Rapid-acting insulins were also found to improve <a href=\"https:\/\/www.diabetes.org\/diabetes\/gestational-diabetes\" target=\"_blank\" rel=\"noopener noreferrer nofollow\">HbA1c levels<\/a> more effectively in people with Type 1 diabetes.<\/p>\n<p>Whether you\u2019re prescribed Humalog, Novolog, or another type of insulin will depend on your overall condition. Consult a healthcare provider for the best insulin for you.<\/p>\n<h2 id=\"insurance-coverage-cost-comparison\">Coverage and cost comparison of Humalog vs. Novolog<\/h2>\n<p>Humalog and Novolog are available in brand and generic forms. Some, but not all Medicare Part D plans will cover insulin except when it\u2019s administered with an insulin pump. When insulin needs to be administered with an insulin pump, Medicare Part B may cover the cost of it. Check with your insurance plan\u2019s formulary to see what\u2019s covered and what your out-of-pocket cost may be.<\/p>\n<p>Even if your insurance plan covers insulin, you may be able to save more with a SingleCare card. The price for generic Humalog can be as much as $300. With a <a href=\"https:\/\/www.singlecare.com\/prescription\/insulin-lispro\">SingleCare coupon<\/a>, it is approximately $145. Similarly, a <a href=\"https:\/\/www.singlecare.com\/prescription\/novolog\">coupon for Novolog<\/a> could reduce the price from $300 to around $150 for 10 ml vial.

However, using these drugs with insulin can also increase the risk of dangerously low blood sugar levels, or hypoglycemia.<\/p>\n<p>Corticosteroids like prednisone or dexamethasone can increase glucose levels in the blood. Therefore, taking these drugs may decrease the effects of insulin. Taking drugs like antipsychotics or diuretics can also decrease the effects of insulin and increase insulin resistance. Insulin dosages may need to be adjusted when taking these other medications.<\/p>\n<p><a href=\"https:\/\/www.singlecare.com\/drug-classes\/beta-blockers\">Beta-blockers<\/a> can alter the effects of insulin. Additionally, beta-blockers can mask the signs of hypoglycemia that can occur after taking an incorrect insulin dose.

Symptoms of low blood sugar may include nausea, hunger, confusion, and weakness. For this reason, it\u2019s recommended to carry glucose tablets to help counteract this potentially life-threatening condition. Therapy with other medications should be carefully coordinated to ensure the right amount of insulin is being administered.<\/p>\n<p>You should avoid using Humalog or Novolog if you have a known sensitivity to either of their active ingredients. Hypersensitivity reactions may include severe rash or trouble breathing (anaphylaxis).<\/p>\n<p>Syringes, pre-filled pens, and cartridges should not be shared with other people who have diabetes.

It is FDA approved to treat Type 2 diabetes in adults and Type 1 diabetes in adults and children aged 3 years and older. Humalog is the brand name for insulin lispro.<\/p>\n<h3>What is Novolog?<\/h3>\n<p>Novolog is a rapid-acting insulin analog that can regulate blood sugar levels in people with diabetes. It is FDA approved to treat Type 2 diabetes in adults and Type 1 diabetes in adults and children aged 2 years and older. Novolog is the brand name for insulin aspart.<\/p>\n<h3>Are Humalog and Novolog the same?<\/h3>\n<p>No, Humalog and Novolog are not the same. They have slightly different formulations, age restrictions, and costs associated with their use.<\/p>\n<h3>Is Humalog or Novolog better?<\/h3>\n<p>Humalog and Novolog are both effective for lowering blood glucose. However, Novolog works slightly faster than Humalog. Compared to long-acting insulins like Lantus (insulin glargine), rapid-acting insulins are more suitable for controlling blood sugar levels before and after a meal. Consult a healthcare provider for the best insulin for your condition.<\/p>\n<h3>Can I use Humalog or Novolog while pregnant?<\/h3>\n<p>According to the <a href=\"https:\/\/www.diabetes.org\/diabetes\/gestational-diabetes\" target=\"_blank\" rel=\"noopener noreferrer nofollow\">American Diabetes Association<\/a>, insulin is the first line of therapy for controlling diabetes while pregnant. It has not been found to cross the placenta. Therefore, it\u2019s deemed safe for use during pregnancy.<\/p>\n<h3>Can I use Humalog or Novolog with alcohol?<\/h3>\n<p>Alcohol should be avoided while using insulin. This is because alcohol can increase the blood sugar lowering effects of insulin and <a href=\"https:\/\/www.singlecare.com\/blog\/alcohol-and-diabetes\/\">potentially cause hypoglycemia<\/a>.<\/p>\n<h3>What is the difference between insulin lispro and insulin aspart?<\/h3>\n<p>Insulin lispro and insulin aspart are two generic forms of fast-acting insulin. However, they are chemically different with slightly different onsets of action. Insulin lispro works within 15 minutes while insulin aspart works within five to 10 minutes. One insulin may also be cheaper than the other depending on your insurance plan.<\/p>\n<h3>What insulin is comparable to NovoLog?<\/h3>\n<p>Novolog is comparable to other fast-acting insulins such as Humalog (insulin lispro) and <a href=\"https:\/\/www.singlecare.com\/prescription\/arida\">Apidra<\/a> (insulin glulisine). Because of their fast onset of action, Novolog, Humalog, and Apidra are often used as mealtime insulins.
