A focused approach to telehealth
We’re developing a telehealth service with clinician evaluation and a pathway for people who already have a prescription.
The diluent comparison
Compare water and saline formulations side by side—from ingredients and preservatives to vial sizes and handling.

The service we’re developing
Our planned service brings genuine manufacturer-labeled diluents and clinician guidance together—whether you need an evaluation or already have a prescription.
Start with a conversation about your prescribed medicine and the diluent it requires. We’re building a pathway for a licensed clinician to evaluate your needs and, when appropriate, prescribe a compatible diluent.
Already have a prescription? We’re planning a separate route to review it alongside the diluent and supplies it calls for, with next steps based on that review.
Describe the medicine and supplies involved, and whether you already have a prescription.
Clinical evaluation or review of an existing prescription would establish the appropriate next step.
Pharmacy coordination, where appropriate, would follow the review.
Explore the essentials
Know what’s in your vial. Explore Hospira / Pfizer water and sodium chloride formulations, with clearly identified ingredients, vial sizes and prescribing information.
Sterile water with benzyl alcohol in a multi-dose vial.
Preservative-free water in a single-dose vial.
0.9% sodium chloride with benzyl alcohol in a multi-dose vial.
Preservative-free 0.9% sodium chloride in a single-dose vial.
Insulin and general-purpose syringes, with the specifications that distinguish them.
From the learning library
What does the preservative change? Compare the formulations and understand why the medicine’s instructions decide.
What should you check before choosing a source? Start with prescription requirements, manufacturer identification and the product label.
Before you explore
We’re developing a telehealth service focused on prescription diluents from established pharmaceutical manufacturers, including Hospira / Pfizer, alongside insulin and general-purpose syringes. The plan includes clinician evaluation and a route for existing prescriptions. Explore the planned service on How it works.
They have different formulations, and the medicine’s prescribing instructions determine the appropriate diluent. Our diluent guides explain the ingredients, vial formats and manufacturer information behind those differences.
Start with Syringes & Needles for insulin and general-purpose syringe guides. They explain capacity, markings and needle or connection details so you can discuss the complete device with your care team.
