Managing Type 2 diabetes can sometimes feel like a daily balancing act. When diet and lifestyle changes are not enough, your doctor may suggest adding a special combination injection to your routine.
This complete patient guide explains everything you need to know about this dual-action diabetes medicine in simple, clear everyday language.
Key Takeaways at a Glance
- This medicine combines a long-acting insulin with a GLP-1 receptor agonist into a single daily injection.
- Take your dose once a day within 60 minutes before your first main meal of the day.
- Never share your injection pen with anyone else, even if you change the needle.
- Always keep fast-acting sugar nearby to treat sudden episodes of low blood sugar.
- Store unopened pens in the refrigerator and your in-use pen at room temperature.
What Is This Medicine and How Does It Work?
This medicine is a combination of two active ingredients: insulin glargine and lixisenatide. Brand names for this combination product include Soliqua.
Insulin glargine is a long-acting insulin that works steadily throughout the day and night to keep your baseline blood sugar levels steady. Lixisenatide is a different type of medicine that slows down how fast food leaves your stomach after you eat. It also tells your pancreas to release insulin only when your blood sugar levels are high.
Together, these two medicines work to lower your blood sugar and keep it in a healthy range. However, this medicine works best when you also follow a healthy diet plan and stay physically active every day.
Things to Tell Your Doctor Before Starting
Before you start using this injection, your doctor needs a complete picture of your health history. Certain medical conditions require extra caution when using this medicine.
Tell your doctor right away if you have any of the following health conditions:
- Frequent episodes of low blood sugar or hypoglycemia.
- Eye problems or vision changes related to diabetes.
- Gallbladder disease or previous gallbladder issues.
- A history of inflammation of the pancreas, known as pancreatitis.
- Kidney disease or if you currently receive kidney dialysis treatments.
- Liver disease or reduced liver function.
- Severe allergic reactions to medicines in the past, including swelling of your face, lips, or tongue.
- Stomach problems that slow down digestion, such as gastroparesis.
- Pregnancy, plans to become pregnant, or if you are breastfeeding.
- A heavy alcohol use disorder or regular heavy drinking habits.
How to Use Your Injection Correctly
Your doctor or nurse will teach you how to give yourself this injection safely. Always follow their exact instructions.
- Injection Site: This medicine is given as a subcutaneous injection beneath the skin. Common injection areas include your abdomen, your upper thighs, or your upper outer arms. Rotate your injection site daily to prevent skin thickening or irritation.
- Timing: Use this medicine once every day. Take it within 60 minutes before your first main meal of the day. Try to take it at the same time each day.
- Check the Liquid: Before every injection, look at the liquid inside the pen window. It should look clear and colorless like water. Do not use the medicine if it looks cloudy, colored, thickened, or contains floating particles.
- Needle Safety: Always remove the outer needle cover before giving your injection. Never reuse needles.
- Disposing of Sharps: Place used needles and syringes into a puncture-resistant sharps container right away after use. Ask your doctor or pharmacist where you can drop off your full container safely.
What to Do for a Missed Dose or Overdose
If You Miss a Dose
Taking your medicine on schedule is important for steady blood sugar control. If you miss a dose, follow your doctor's specific instructions for missed doses. Never take a double dose to make up for a missed injection. Taking two doses at once can cause your blood sugar to drop to dangerous levels.
If You Take Too Much
If you suspect you have taken too much medicine, get emergency medical help right away. Go to the nearest emergency department or call your local emergency number.
