Insulin is a crucial medication for individuals managing diabetes, and its effectiveness is highly dependent on proper storage and handling.

The following guidelines are essential to ensure that insulin remains potent and safe for use:

Refrigeration: Unopened vials and pens should be stored in the refrigerator at a temperature between 36°F and 46°F (2°C to 8°C).

Avoid placing insulin in the freezer, as freezing can render it ineffective.

Room Temperature Use: Once opened, insulin can be kept at room temperature (up to 77°F or 25°C) for up to 28 days, depending on the type.

Always refer to the manufacturer’s guidelines for specific products.

Avoid Direct Sunlight: Store insulin away from direct sunlight to prevent degradation. This can be achieved by keeping the medication in its original packaging until it is time to use it.

Proper Techniques: Always wash hands before handling insulin. When drawing insulin from a vial, use a new, sterile syringe or pen needle.

Ensure that the needle doesn’t touch any non-sterile surfaces to maintain its sterility.

Mixing Insulin: If using a combination of rapid-acting and NPH insulins, always draw the clear insulin (rapid-acting) into the syringe first to avoid contamination.

Safe Disposal: Any insulin that has expired or has been stored improperly should not be used.

Dispose of used syringes and insulin vials according to local regulations, often in a designated sharps container.

Visual Inspection: Regularly inspect insulin for discolouration, cloudiness (when it shouldn’t be), or any particles.

If any abnormalities are observed, do not use that insulin.

By adhering to these best practices, individuals can ensure that their insulin remains effective, thereby effectively managing their diabetes and reducing risk factors associated with improper insulin usage.
