What supplies are needed for a person using insulin therapy?

Essential Supplies for Insulin Therapy

People using insulin therapy require insulin delivery devices (syringes, pen needles, or pump supplies), blood glucose monitoring equipment, sharps disposal containers, and spare insulin supplies. 1

Core Insulin Delivery Supplies

Insulin Administration Devices

• Insulin syringes for use with insulin vials, or pen needles (such as NovoFine disposable needles) for use with insulin pens 1, 2
• The shortest needles (4-mm pen needles and 6-mm syringe needles) are the first-line choice for all patients as they are safe, effective, and less painful while avoiding intramuscular injections 3
• Insulin pens (either disposable pre-filled pens or reusable pens with cartridges) are increasingly preferred over vials and syringes 2
• For patients on continuous subcutaneous insulin infusion (CSII), insulin infusion sets that should be changed every 48-72 hours 4

Insulin Storage Requirements

• A spare bottle of each type of insulin used must always be available 1
• Insulin in use may be kept at room temperature to reduce injection site irritation from cold insulin 1
• Patients should inspect insulin bottles before each use for changes including clumping, frosting, precipitation, or changes in clarity or color 1

Blood Glucose Monitoring Equipment

• Blood glucose meter and test strips for self-monitoring of blood glucose (SMBG), which is integral to effective insulin therapy 1, 3
• Lancets for obtaining blood samples 2
• Frequent patient-performed blood glucose measurements are necessary to achieve effective glycemic control and avoid both hyperglycemia and hypoglycemia 2

Sharps Disposal

• Puncture-resistant sharps containers (such as red biohazard containers, hard plastic containers like detergent bottles, or metal containers like empty coffee cans) 1, 2
• Used syringes, needles, and lancets must be placed in these containers and disposed of according to local regulations 1
• Never recap, bend, or break needles as this increases the risk of needle-stick injury 1
• Remove and dispose of pen needles immediately after each injection without recapping 2

Additional Essential Supplies

Hypoglycemia Treatment

• Fast-acting carbohydrates such as fruit juice, sugar candies, or glucose tablets to treat mild hypoglycemia 2
• Glucagon injection kit may be needed for severe hypoglycemia requiring emergency treatment 2

Injection Site Care

• Alcohol swabs for cleaning the rubber stopper on insulin vials and potentially for skin preparation 2

Critical Safety Considerations

• Never share insulin pens, pen cartridges, or small individual vials between patients to prevent transmission of blood-borne diseases like HIV or hepatitis, even with a new needle 4
• Insulin pens and cartridges should be clearly labeled with patient names in healthcare facilities where common storage is used 4
• Always carry an extra insulin pen or vial in case the current one is damaged or lost 2

Needle Reuse Caution

While manufacturers recommend single-use only for disposable syringes and pen needles, some patients reuse needles for financial reasons 1, 3. However, needle reuse is associated with lipohypertrophy (lumpy, firm injection sites that impair insulin absorption) and cannot guarantee sterility 1, 3. Patients with poor personal hygiene, acute illness, open wounds on hands, or decreased resistance to infection should be particularly cautious about reuse 1.

Site Rotation Strategy

• Patients need a systematic rotation plan to prevent lipohypertrophy 4
• Injections should be moved at least half an inch (1 cm) away from the previous injection site 4
• Rotation should occur within appropriate injection areas: abdomen, upper arms, thighs, and buttocks 1, 2
• Never inject into areas with lipohypertrophy as insulin absorption will be impaired 4
