What is Insulin Degludec?
Insulin Degludec is a prescription medicine used to help manage diabetes. It is classified as a long-acting insulin. Once you inject it, the medicine releases slowly into your body to keep your blood sugar levels stable throughout the day and night.
The main goal of this medicine is to lower your blood glucose levels and prevent high blood sugar spikes. However, taking this injection alone is not enough. You must also follow a healthy meal plan and stay physically active as recommended by your doctor.
Before You Start Using This Medicine
Before you take your first dose, you must share your complete medical history with your doctor. Certain health conditions can change how your body reacts to insulin and help your doctor choose the safest dose for you.
| Your Health Condition | Why Your Doctor Needs to Know |
|---|---|
| Frequent episodes of low blood sugar | Insulin can lower your blood sugar further, requiring careful dose adjustments. |
| Eye diseases or vision problems | Rapid changes in blood sugar can sometimes affect existing eye conditions. |
| Kidney disease | Damaged kidneys clear insulin more slowly, which may require a lower dose. |
| Liver disease | Your liver helps process insulin and store glucose, so function matters. |
| Allergies to insulin or other medicines | Prevents severe allergic reactions or dangerous hypersensitivity issues. |
| Pregnancy, planning pregnancy, or breastfeeding | Hormonal shifts change insulin needs greatly during these stages. |

Check Availability →How to Use This Injection Properly
You inject this medicine just beneath the skin, which is called a subcutaneous injection. Your doctor or diabetes nurse will teach you the correct injection technique during your visit.
Always follow your prescribed dose carefully. Never change your dose or take more than your doctor instructed without checking with them first.
Inspect the liquid before every injection. The medicine should look completely clear and colorless like water. If you notice it looks cloudy, thickened, colored, or contains solid particles, do not use it.
Never mix Insulin Degludec with any other type of insulin in the same syringe. Doing so can change how the medicines work and cause dangerous blood sugar fluctuations.
If you use an insulin pen, always remove the outer needle cover before giving your injection. Always dispose of used needles safely in a rigid puncture-resistant sharps container rather than throwing them in your regular household trash.
What to Do If You Take Too Much Medicine
If you believe you accidentally took a higher dose of insulin than prescribed, do not panic. Stay calm and act quickly. Contact your local emergency medical services or go right away to the nearest hospital emergency department for monitoring and treatment.
What to Do If You Miss a Dose
If you forget to take your scheduled dose of insulin, take it as soon as you remember. However, make sure there is at least an 8-hour gap before your next scheduled dose. Never take two doses at the same time to make up for a missed injection.
Other Substances That Can Interact with This Medicine
Always share a complete list of everything you take with your doctor. This includes prescription drugs, over-the-counter painkillers, vitamins, and herbal supplements. Many substances can alter how well your insulin works.
Common substances that interact with insulin include:
- Alcohol consumption, which can cause unpredictable drops or spikes in blood sugar.
- Other diabetes medicines that increase the risk of low blood sugar.
- Beta-blockers used for high blood pressure, which can mask warning signs of low blood sugar like shaking or fast heartbeat.
- Painkillers such as ibuprofen or naproxen.
- Steroids like prednisone, which tend to raise blood sugar levels.
- Cold, cough, and allergy medicines containing certain active ingredients.
- Cigarette smoking and tobacco use.
This list is not exhaustive. Always consult your doctor before starting any new product while on insulin therapy.
Important Safety Precautions While Taking This Medicine
Taking insulin requires daily vigilance and regular medical checkups to ensure your treatment plan remains safe and effective.
- Never miss your scheduled clinic appointments so your doctor can track your overall progress.
- Get regular HbA1c blood tests to check your average blood sugar control over the past two to three months.
- Learn how to check your blood glucose levels at home and know the signs of high and low blood sugar.
- Keep fast-acting carbohydrates, such as glucose tablets or hard candies, with you at all times in case your blood sugar drops.
- Never skip meals after taking your insulin injection.
- Carry a medical alert card or wear a bracelet stating that you use insulin in case of an emergency.
When to Seek Emergency Help
Call 911 (US/Canada), 999 (UK), or go to your nearest Emergency Department right away if you experience severe symptoms of very low blood sugar (such as confusion, fainting, or seizures) or signs of a severe allergic reaction like trouble breathing or swelling of your face and tongue.
Possible Side Effects
Like all medicines, Insulin Degludec can cause side effects, though not everyone experiences them. Knowing what to watch for helps you stay safe.
Contact your doctor right away if you notice:
- Signs of an allergic reaction, such as skin rashes, itching, or swelling of the face, lips, tongue, or throat.
- Symptoms of low blood sugar, including shaking, sweating, chills, dizziness, anxiety, or a fast heartbeat.
- Signs of low potassium levels, such as muscle cramps, unusual weakness, or irregular heartbeats.
Common, less severe side effects that you should mention to your doctor if they persist include:
- Lipodystrophy, where the skin thickens or pits at the injection site. Rotate your injection spots regularly to prevent this.
- Mild pain, redness, or minor swelling right where you injected the medicine.
- Gradual weight gain, which can sometimes occur when starting insulin therapy.
