Admelog is being discontinued: switching back to Humalog
Admelog (a lispro rapid insulin) is being discontinued across 2026, with the original brand Humalog available to take its place and cover demand.
If Admelog is your fast insulin, it is being discontinued across 2026, and you will most likely be switched to Humalog. The reassuring part: Admelog and Humalog are the same insulin (lispro), just different brands, so this is meant to be a straight swap rather than a change of treatment. The main thing to do is notice the name change on your prescription and ask your pharmacist to confirm it is a direct swap. As with any supply change, never change your own doses off the back of a news item; that stays a conversation with your team.
- Admelog and Humalog are both insulin lispro, a rapid (mealtime) insulin, so this is a brand change, not a different medicine.
- Admelog is being discontinued across 2026, and Humalog, the original brand, can fully cover the switch.
- Teams and pharmacies are moving people over well before Admelog runs out, so there should be no gap.
- The switch is designed to be like-for-like, and your pharmacist can confirm it is a direct swap.
- Watch for the name change on your next prescription, and take any dose questions to your team, not a website.
What is happening, and why it is a gentle one
Admelog is a brand of insulin lispro, a rapid-acting insulin taken around meals. It is being discontinued across 2026, with its cartridges, pens and vials running out at different points through the year. The reason this is one of the easier supply changes to take in is that its replacement is not a new or different insulin. It is Humalog, the original brand of the very same insulin, lispro, and there is enough of it to cover everyone moving across.
Because it is the same insulin, teams and pharmacies can move people over in a planned way, well before Admelog actually runs out. In practice, what you are most likely to notice is simply the brand name changing on your prescription and on the box you pick up. There should be no gap in supply, and no need to stockpile Admelog while the switch happens.
A like-for-like switch, and the one thing to confirm
Even though this is a straight swap, it is worth being a little bit active about it. When your prescription changes, check that the new name is Humalog and that your pharmacist agrees it is replacing your Admelog directly. That quick confirmation avoids any confusion at the counter, especially on repeat prescriptions where the old name might linger on paperwork.
Because Admelog and Humalog are the same insulin, the switch is meant to work exactly as your current insulin does. Everyone is a little different, though, so if you do notice unexpected highs or lows after the change, that is worth flagging to your team rather than adjusting anything yourself. Whether any dose ever needs looking at is a decision for them, made with you, and not something to read off a news story.
