Where to Buy Insulin Syringes: How to Choose and Order Sensifine Insulin Syringes

If you're wondering where to buy insulin syringes, there are 2 main routes: the pharmacy counter and online suppliers.

In most areas of the United States, insulin syringes may be legally purchased without a prescription, but a few states and counties have their own rules. This guide covers both routes, Sensifine's prescription requirements by location, and the 7 Sensifine insulin syringe sizes.

Can You Buy Insulin Syringes Without a Prescription?

In most areas of the United States, yes. Insulin syringes may be legally purchased without a prescription, but you are responsible for complying with the laws of your state, and Sensifine reserves the right to refuse any order that would violate federal, state, or local laws or regulations. State rules do differ. California, for example, allows a pharmacist or physician to furnish a syringe for administering insulin without a prescription.[2]

How to Choose: A Three-Step Check

1. Check your insulin concentration.
   Sensifine syringes are for U-100 insulin, which means 100 units per milliliter. If your insulin is a different concentration, ask your pharmacist about the right syringe.
2. Match the capacity.
   On a U-100 syringe, a 0.5cc barrel holds up to 50 units and a 1cc barrel holds up to 100 units.[3] Your prescriber or pharmacist can tell you which capacity fits your prescribed dose.
3. Match the gauge and length.
   Gauge is thickness, and a higher number means a thinner needle. Length here is 8mm or 12mm. These are set by you and your care team, and injection-technique guidance generally leans toward shorter needles, so talk to them before changing the length you use.[4]

Don't Forget Safe Disposal
