Built so dosing feels routine, not stressful

See your dose before you inject

The large window shows the number you dialed and how much is left in the cartridge.

Dialed too far? Turn it back

The bidirectional dial lets you correct your setting without losing any medication.

No proprietary refills

Uses standard 3 mL glass cartridges and ISO standard pen needles, so supplies are easy to find.

Why a reusable pen makes sense

If you inject regularly, one well-made pen does the work of many disposables.

Questions, answered

No. The NEST Pen works with any ISO standard disposable pen needle, sold separately. Use a new sterile needle for every injection.
Standard 3 mL glass cartridges. There are no proprietary refills.
Yes. The pen is built for long-term daily use. When a cartridge is empty, you replace the cartridge, not the pen.
Your physician's instructions tell you how many units to dial for each dose. If anything is unclear, contact us at support@lavimd.store or 844-954-9300 before your first injection.
Turn the dial back down. It moves in both directions, so you can correct the setting before injecting.
Many people keep one pen at home and another in a bag, at the office, or for travel. The 2 Pen Pack saves 10%. The 3 Pen Bundle adds a box of 10 cartridges and a pack of needles, so you have everything you need to start.
No. Each pen is for one person only, even if the needle is changed.
Remove the needle after every injection and keep the pen in its case. Wipe the outside with a damp cloth as needed. Store medication as directed on its label.
Yes. The slim case fits in a purse or carry-on. When flying, keep your pen and medication in your carry-on.
