Instructions for Humalog Vial Insulin Storage Temperature Conditions

Instructions for Humalog Vial Insulin Storage Temperature Conditions

What is Humalog?

Humalog is a fast-acting insulin that is used to treat patients with diabetes mellitus. As a fast-acting insulin, the drug starts to work within 15 minutes to reduce blood sugar levels. As a result, it is advisable you take this medicine within 15 minutes before you eat a meal. Humalog is the brand name of insulin lispro. When you inject insulin lispro into the fat tissue of the skin, it works by helping the body tissue store glucose for energy. This helps to lower high levels of blood sugar. The drug also works by preventing the liver from releasing more glucose into the bloodstream.

How to take this medication

Before you start taking Humalog, make sure you are not allergic to insulin lispro or experiencing episodes of hypoglycemia. Inform your doctor if you are using other medications, like other oral diabetes drugs, before you start taking Humalog. There are certain types of oral diabetes drugs that can increase your risk of heart problems if you take them with Humalog. This insulin medication can be taken subcutaneously or injected into a vein. You should not inject insulin lispro if you do not understand how to administer it safely from home.

Unopened Humalog is to be stored in a refrigerator between the temperatures of 2°C and 8°C. You should not store it under freezing temperatures or inside a freezer.
