Insulin Options: Pens vs. Pumps for Type 2 Diabetes

Managing diabetes has come a long way, and today, there are more tools than ever to help you take control. If you’re wondering whether an insulin pen or insulin pump is the better fit for your lifestyle, here’s a breakdown of the pros and cons of each option.

(By the way, switching from pens to a pump—or vice versa—should always be done with guidance from your healthcare team!)

Using an insulin pen

Pros:

• Affordable and simple: Pens are less expensive and easier to use than pumps, with no need for infusion site changes or complex programming.
• Reliable delivery: Pens rarely fail to deliver insulin properly, unlike pumps, which can have technical issues.
• Smart features: Many pens now come with apps to track doses, insulin on board, and even help calculate doses.
• Physical freedom: Pens aren’t attached to your body, so they’re more discreet and comfortable.
• Travel-friendly: Pens require fewer backup supplies, making them easier to carry on the go.
• Fewer skin issues: Pens cause less skin irritation and scarring compared to pump infusion sites.

Cons:

• Less flexibility: Long-acting insulin from pens can’t be adjusted once injected, making it harder to adapt to exercise or other changes.
• More injections: Pens require multiple daily injections, which can be a hassle if you dislike needles.
• No automation: Pens don’t calculate doses or deliver insulin automatically, so there’s more mental math involved.
• Easier to forget: Without a device attached to remind you, it’s easier to miss a dose.

Using an insulin pump

Pros:

• Customizable dosing: Pumps allow precise adjustments to basal (background) insulin and bolus (mealtime) insulin.
• Automation: Many pumps calculate doses for meals and corrections, taking the guesswork out of insulin management.
• Flexibility: Pumps can deliver extended or split boluses for high-fat or high-protein meals, reducing the need for follow-up doses.
• Better control: Pumps often help users stay in their target blood sugar range more consistently, especially during exercise or stress.
• Harder to forget: Since pumps are worn on your body, they’re a constant reminder to manage your insulin.

Cons:

• Higher cost: Pumps are more expensive than pens due to the technology and supplies required.
• Frequent site changes: Infusion sites need to be replaced every 1-3 days, which can be inconvenient.
• Visibility: Pumps are more noticeable than pens, which might bother some users.
• 24/7 wear: Pumps must be worn all day, which can feel restrictive.
• Skin issues: Infusion sites can cause irritation, scarring, or even infections if not managed properly.
• Backup supplies: Pumps require you to carry extra supplies, especially when traveling.
