Technique tutorials

Four written lessons: reconstitution, syringe measurement, pen setup and nasal pumps. Each step has a checkpoint, and no account is needed to follow along.

A vial of lyophilized peptide, a vial of bacteriostatic water and a U-100 insulin syringe on a pale surface.

Nasal spray bottle and pump setup

Check that the liquid is made for nasal use, confirm the bottle size and verify how much the pump releases per spray.

  1. Check that the instructions for the exact product clearly say it can be used as a nasal spray.

  2. They should also list the correct mixing liquid, concentration range, preparation steps and storage.

Before you continue

The same instructions support the nasal route, the product and the mixing liquid. Nothing was copied from injectable instructions.

Stop conditions

Stop if you cannot confirm that the product, preservative and prepared mixture are suitable and stable for nasal use.

Safety boundary

Do not use injectable mixing instructions for a nasal spray. The exact product and mixing liquid must be suitable for nasal use.
