Gvoke (glucagon) is injected under the skin during a medical emergency when you have dangerously low blood sugar and you aren't able to eat or drink anything with sugar by mouth. It comes in an auto-injector pen or a pre-filled syringe that many people find easier to use than a traditional glucagon kit. But like other emergency glucagon injections, it can also cause side effects like nausea and vomiting.
Severely low blood sugar (hypoglycemia) in adults and children age 2 years and older
Gvoke (glucagon) is glucagon, a hormone that your body makes to raise blood sugar levels when the levels are too low.
Typically, your body stores the sugar you get from food in your liver until it needs the sugar at a later time. When your blood sugar is too low, glucagon tells your body to release the stored sugar into your bloodstream. When this happens, your blood sugar level goes up.
Usually, your body can sense and control your blood sugar levels. But this system doesn't work as well if you have diabetes or if you take too much insulin.
Gvoke (glucagon) works to raise your blood sugar levels if they become too low.

Always make sure that you know how to recognize signs of low blood sugar (e.g., shakiness, dizziness, and feeling irritable) and know how to quickly give yourself Gvoke (glucagon). It's also a good idea to review this information with people you're close with, since you might need them to give you the injection in case you pass out.
Read the instructions for use for [Gvoke (glucagon) HypoPen, pre-filled syringe, or kit so that you're familiar and comfortable using the medication during an emergency. There are also instructional videos available to help you use the device correctly.
If you need to use Gvoke (glucagon), it's a good idea to call 911 and get emergency medical help while you wait for the medication to work. The medical crew can check your blood sugar levels and provide any additional care or medical documentation that you might need in the future.
If you're using Gvoke (glucagon) HypoPen or pre-filled syringe, don't take your medication out of the foil pouch until you're ready to use it. If you're using Gvoke (glucagon) vial and syringe kit, keep your medication in the original container until you need it.
Before injecting yourself with Gvoke (glucagon), look at the solution to make sure it's clear and colorless to pale yellow and free from any specks floating inside. If the medication is a different color or contains specks, don't use it.
After your blood sugar level improves with Gvoke (glucagon), eat or drink something that contains sugar (like hard candy, juice, or non-diet soda) as soon as you are able to swallow. This'll help to prevent your blood sugars from getting too low again.
Don't reuse Gvoke (glucagon) even if you see some solution still left over. Each Gvoke (glucagon) device or vial contains a single dose only and can't be used again. Please get a refill as soon as possible after you have used the medication or if it's about to expire.
Gvoke (glucagon) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Risk factors: Pheochromocytoma (tumor above the adrenal glands)
Don't use Gvoke (glucagon) if you have a rare tumor called pheochromocytoma. This is because Gvoke (glucagon) can trigger the release of certain hormones that can cause your blood pressure to become dangerously high. If you have this condition, ask your provider about safer ways to treat dangerously low blood sugar.
Risk factors: Insulinoma (tumor in the pancreas)
Avoid Gvoke (glucagon) if you have a type of tumor called insulinoma. Using Gvoke (glucagon) can trigger the tumor to release more insulin, which can put you at high risk for dangerously low blood sugar. If you have this tumor, your provider might suggest other ways to manage low blood sugar.
Risk factors: Starvation | Problems with adrenal glands | Low blood sugar for long periods of time
Gvoke (glucagon) only works if you've been eating a healthy diet and your liver has already stored up enough sugar. It won't work well if you have constantly low blood sugar because of a poor diet, or if you have issues with your adrenal glands. Talk to your provider about how to treat low blood sugar if you have these conditions.
Risk factors: Tumors that make glucagon
People with tumors that make glucagon have reported a very serious skin rash after they have received continuous glucagon infusion. The skin rash can involve open sores, fluid-filled blisters, and dry and scaly skin on the face, groin, and legs. In reported cases, the rash went away after people stopped using glucagon. This reaction is likely rare with Gvoke (glucagon) because this medication isn't a glucagon infusion, but rather a small dose of glucagon given under the skin. But if you have this type of tumor and you're concerned about this reaction, talk with your provider to see whether Gvoke (glucagon) is appropriate for you.
