Admelog vs novolog?

Short answer: Admelog and NovoLog are both rapid-acting insulins, but they are different molecules and aren’t exactly interchangeable.

Key differences at a glance
- What they are:
- Admelog: insulin lispro (rapid-acting). Biosimilar to Humalog; made by Sanofi.
- NovoLog: insulin aspart (rapid-acting). Brand-name product made by Novo Nordisk.
- How they work and what they’re for:
- Both are used to control blood sugar around meals in adults and children with type 1 or type 2 diabetes.
- They’re both rapid-acting insulins that help cover post-meal glucose rise.
- Onset, peak, duration (typical ranges; can vary by person):
- Admelog (lispro): starts about 15 minutes after injection; peaks around 1–2 hours; lasts about 3–5 hours.
- NovoLog (aspart): starts about 10–20 minutes after injection; peaks around 1–3 hours; lasts about 3–5 hours.
- Dose and switching:
- They deliver insulin in units, but a 1:1 unit conversion between lispro (Admelog) and aspart (NovoLog) is not guaranteed. If you switch between them, your doctor may adjust the dose based on blood sugar monitoring.
- Formulations and devices:
- Admelog is available in vials and in pens (SoloStar-style delivery is common for lispro products).
- NovoLog is available in vials and in pens (FlexPen/NovoPen) and also as premixed NovoLog Mix 70/30.
- Special considerations:
- Both carry the risk of hypoglycemia and should be used as part of a structured plan (with dietary changes, activity, and monitoring).
- Pregnancy: both lispro and aspart insulins are generally considered safe options when insulin is needed in pregnancy, but your provider will choose and monitor the best option for you.
- Cost and biosimilarity:
- Admelog is a biosimilar to Humalog and is often cheaper than Humalog. NovoLog is a brand-name product; pricing varies by payer and region.
- Practical notes:
- Do not assume you can interchange brands freely without medical advice.
- If you’re switching products or devices, monitor your blood sugar closely and follow your healthcare provider’s dosing plan.

Bottom line
- Admelog = insulin lispro (rapid-acting), biosimilar to Humalog.
- NovoLog = insulin aspart (rapid-acting), brand-name.
- They’re both rapid-acting options for meal coverage, but they’re not identical. If you’re considering switching from NovoLog to Admelog (or vice versa), talk to your healthcare provider about dose adjustments and monitoring to maintain good blood sugar control. If you want, tell me your current regimen (type of diabetes, typical meals, any recent glucose readings) and I can help outline what to discuss with your clinician.
