FAQs
What are the most common side effects of once‑a‑week insulin?
The most frequent are mild hypoglycaemia, occasional injection‑site redness or itching, and a modest weight gain of 1‑3 kg.
How often should I check my blood glucose after starting weekly insulin?
Check before the injection, then at 24 h, 48 h, and 72 h for the first dose. After stabilising, a weekly check on injection day plus spot checks when you feel “off” is usually enough.
Is weekly insulin safe for people with kidney disease?
Yes, but dose adjustments are needed if eGFR is below 60 ml/min/1.73 m². Regular kidney function tests every 3‑6 months are recommended.
Can I switch back to daily basal insulin if I experience problems?
If you have more than two severe hypoglycaemic episodes per month, steady weight gain over 5 kg, or worsening kidney numbers, discuss reverting to daily insulin with your doctor.
Do I need to rotate injection sites with a weekly shot?
Absolutely. Rotate between abdomen, thigh, and buttock each week to minimise tissue buildup and reduce irritation.
