What is Insulin Aspart and Insulin Degludec: Uses, Dosage, Side Effects and More

Insulin aspart and insulin degludec is a combination diabetes medication that helps control blood sugar levels throughout the day. This medicine combines two different types of insulin that work together to manage your diabetes more effectively than using just one type alone.

This combination medication is designed to give you both quick-acting and long-lasting blood sugar control. The insulin aspart works fast when you eat, while the insulin degludec provides steady background insulin for up to 24 hours.

What is Insulin Aspart and Insulin Degludec?

This medication contains two manufactured versions of the insulin your body naturally makes. Insulin aspart is a rapid-acting insulin that starts working within 10-20 minutes after injection, while insulin degludec is a long-acting insulin that provides steady coverage for more than 24 hours.

Think of this combination as having both a sprinter and a marathon runner on your diabetes management team. The aspart component quickly handles the sugar from your meals, while the degludec component steadily manages your background insulin needs all day and night.

This medicine comes as a clear, colorless solution that you inject under your skin using a special pen device. It's a prescription medication that requires careful monitoring and dosing by your healthcare provider.

What is Insulin Aspart and Insulin Degludec Used For?

This combination insulin is prescribed to help adults and children with diabetes control their blood sugar levels. It's used when your body either doesn't make enough insulin or can't use the insulin it makes effectively.

Your doctor might recommend this medication if you have type 1 diabetes, where your body produces little to no insulin. It's also used for type 2 diabetes when other medications haven't provided adequate blood sugar control.

The combination is particularly helpful for people who need both mealtime insulin coverage and steady background insulin throughout the day. This can simplify your diabetes management by reducing the number of daily injections you need.

How Does Insulin Aspart and Insulin Degludec Work?

This medication works by replacing or supplementing the insulin your body should naturally produce. Insulin acts like a key that opens the door for sugar to enter your cells, where it can be used for energy.

The insulin aspart component is considered a strong, fast-acting insulin that quickly moves sugar from your bloodstream into your cells after meals. It peaks within 1-3 hours and typically lasts 3-5 hours in your system.

The insulin degludec component provides a steady, moderate release of insulin that works continuously for more than 24 hours. This helps maintain stable blood sugar levels between meals and overnight when you're not eating.

Together, these two insulins create a comprehensive approach to blood sugar management that mimics your body's natural insulin patterns more closely than single-type insulin medications.

How Should I Take Insulin Aspart and Insulin Degludec?

You'll inject this medication under the skin of your thigh, upper arm, or abdomen using the pre-filled pen provided. Your doctor will show you the proper injection technique and help you choose the best injection sites.

Take this medication once or twice daily as prescribed by your healthcare provider. The timing depends on your specific diabetes management plan and blood sugar patterns throughout the day.

You can take this insulin with or without food, but it's important to maintain consistent timing with your meals and injections. If you're taking it with meals, inject it just before eating to help manage the rise in blood sugar that comes with food.

Rotate your injection sites to prevent skin problems like lumps or thickening. Don't inject into areas that are red, swollen, or tender, and avoid injecting through clothing.

Always check the medication before injecting to make sure it's clear and colorless. Don't use it if it appears cloudy, colored, or contains particles.

How Long Should I Take Insulin Aspart and Insulin Degludec For?

Most people with diabetes need to take insulin for the rest of their lives to maintain healthy blood sugar levels. This medication is typically a long-term treatment rather than a short-term fix.

Your doctor will regularly monitor your blood sugar levels and adjust your dosage as needed. Factors like changes in your weight, activity level, stress, illness, or other medications can affect how much insulin you need.

Some people with type 2 diabetes might eventually need less insulin if they make significant lifestyle changes or if their pancreas begins producing more insulin naturally. However, this varies greatly from person to person.

Never stop taking this medication without talking to your healthcare provider first. Stopping insulin suddenly can lead to dangerously high blood sugar levels and serious complications.

What Are the Side Effects of Insulin Aspart and Insulin Degludec?

Like all medications, this insulin combination can cause side effects, though most people tolerate it well. The most common side effect is low blood sugar, which can happen if you take too much insulin, skip meals, or exercise more than usual.

Here are the most frequently reported side effects you might experience:

• Low blood sugar (hypoglycemia) with symptoms like shakiness, sweating, fast heartbeat, or confusion
• Redness, swelling, or itching at injection sites
• Weight gain as your body begins using sugar more effectively
• Headaches, especially when starting the medication
• Upper respiratory tract infections like colds

These common side effects often improve as your body adjusts to the medication and you become more experienced with managing your dosing and timing.

Some people may experience less common but more concerning side effects that require medical attention:

• Severe allergic reactions with difficulty breathing, swelling of face or throat, or widespread rash
• Severe low blood sugar that causes confusion, seizures, or loss of consciousness
• Skin changes at injection sites, including thickening, pitting, or lumps
• Unusual swelling in hands, feet, or ankles
• Vision changes or eye problems

These serious side effects are rare but require immediate medical attention if they occur. Most people use this medication safely for many years with proper monitoring and education.

Who Should Not Take Insulin Aspart and Insulin Degludec?

This medication isn't right for everyone, and certain medical conditions or situations may make it unsafe for you to use. Your doctor will carefully review your medical history before prescribing this insulin combination.

You should not use this medication if you're currently experiencing low blood sugar or if you have a known allergy to insulin aspart, insulin degludec, or any ingredients in the medication.

People with certain health conditions need extra caution and closer monitoring when using this insulin:

• Kidney disease, as this can affect how your body processes insulin
• Liver disease, which can impact blood sugar control
• Heart problems, especially heart failure
• Thyroid disorders that affect metabolism
• Adrenal gland problems
• History of severe allergic reactions to other insulins

Pregnancy and breastfeeding require special consideration, though insulin is generally considered safe during these times. Your doctor will help you determine the best diabetes management approach if you're pregnant or planning to become pregnant.

Children under certain ages may not be candidates for this specific combination, depending on their individual needs and the available research on safety and effectiveness in pediatric populations.

Insulin Aspart and Insulin Degludec Brand Names

This combination medication is available under the brand name Ryzodeg, which is manufactured by Novo Nordisk. Ryzodeg contains 70% insulin degludec and 30% insulin aspart in each dose.

The medication comes in a pre-filled pen device called FlexTouch, which is designed to make injections easier and more accurate. This pen allows you to dial your exact dose and has features that help ensure proper injection technique.

You might also hear healthcare providers refer to this medication by its generic name or by the individual insulin components. However, when prescribed, it will typically be written as Ryzodeg or the specific insulin aspart/degludec combination.

Insulin Aspart and Insulin Degludec Alternatives

Several other insulin options are available if this combination doesn't work well for you. Your doctor might consider other rapid-acting insulins like insulin lispro or insulin glulisine combined with different long-acting insulins.

Other long-acting insulin options include insulin glargine and insulin detemir, which can be paired with rapid-acting insulins for similar blood sugar control. Some people do well with pre-mixed insulin combinations that contain different ratios of fast and long-acting insulins.

For people with type 2 diabetes, non-insulin alternatives might include medications like metformin, GLP-1 receptor agonists, or SGLT-2 inhibitors. These work differently than insulin but can be effective for blood sugar management in the right circumstances.

Your healthcare provider will help you find the best medication regimen based on your specific needs, lifestyle, and how well you respond to different treatments. What works best varies significantly from person to person.

Is Insulin Aspart and Insulin Degludec Better Than Other Insulin Combinations?

This combination offers some unique advantages compared to other insulin regimens, but whether it's "better" depends on your individual needs and circumstances. The main benefit is the convenience of getting both rapid and long-acting insulin in one injection.

Compared to taking separate rapid-acting and long-acting insulins, this combination can reduce the number of daily injections you need. The insulin degludec component also provides very stable, long-lasting coverage that may result in fewer blood sugar fluctuations.

Some studies suggest that insulin degludec may cause less nighttime low blood sugar compared to other long-acting insulins like insulin glargine. This can be particularly beneficial for people who experience frequent overnight hypoglycemia.

However, separate insulins offer more flexibility in adjusting doses independently. With the combination, you can't adjust just the rapid-acting or just the long-acting component without affecting both.

Your doctor will help you weigh these pros and cons based on your blood sugar patterns, lifestyle, and personal preferences to determine what works best for your diabetes management.
