Every-Two-Week Diabetes Shot Works as Well as Weekly

What This Study Found

Researchers tested whether a diabetes injection taken every two weeks could work just as well as one taken every week. After 12 weeks, both groups saw their HbA1c (a measure of average blood sugar over time) drop by about 1.5%. Time spent in a healthy blood sugar range also improved dramatically in both groups — jumping from around 45% to over 75%.

Why This Matters for You

If you take a weekly GLP-1 injection for type 2 diabetes, you know that sticking to a weekly schedule can be challenging. Forgetting a dose, managing injection supplies, or simply dealing with injection fatigue are real problems. A biweekly option — meaning one shot every two weeks — could make staying on track much easier for many people.

This study looked at a drug called efsubaglutide alfa, which belongs to the same GLP-1 receptor agonist class as other well-known diabetes medications. Participants were adults whose blood sugar was not well controlled by lifestyle changes alone.

What the Numbers Show

• HbA1c dropped about 1.5% in both the every-two-week and every-week groups — a meaningful improvement.
• Time in Range (TIR) — the percentage of the day blood sugar stays in a healthy zone — rose from 45% to about 77% with biweekly dosing and 75% with weekly dosing.
• Fasting blood sugar fell by similar amounts in both groups.
• No hypoglycemia (dangerously low blood sugar) occurred in either group.
• Side effects were mostly mild stomach issues, which are common with this class of medication.

Important Limitations to Keep in Mind

This was a small study — only 59 people — and it only lasted 12 weeks. The researchers themselves stress that larger, longer studies with more diverse groups of people are needed before biweekly dosing becomes a standard option. This drug is also not yet widely available. Think of this as promising early evidence, not a definitive answer.

What This Means for CGM Users

One exciting part of this study is that researchers used continuous glucose monitors (CGMs) to track blood sugar around the clock — not just a single snapshot. This gave a much fuller picture of how well each dosing schedule worked throughout the day and night. The fact that both groups reached similar time-in-range scores is especially reassuring.

If you use a CGM to manage your type 2 diabetes, tools and supplies that keep your device running smoothly matter just as much as your medication schedule. MDS Diabetes (mdsdiabetes.com) carries a wide range of CGM accessories and diabetes management supplies to support your daily routine.

Talk to Your Doctor

Efsubaglutide alfa is still being studied and is not yet a standard treatment option. Do not change your current medication schedule based on this research. Always speak with your healthcare provider before making any changes to your diabetes management plan.
