BD Lo-Dose Micro-Fine Insulin Syringes

For people managing diabetes with smaller insulin doses, the BD Lo-Dose Micro-Fine syringe is built around one purpose: making low-volume dosing accurate and comfortable. The 0.5 mL barrel carries an expanded, easy-to-read scale, so measuring doses of 50 units or fewer is far more precise than trying to read the same amount on a full-size syringe. That extra visual space matters when a difference of a unit or two counts.

These are U-100 syringes, meaning they're calibrated for standard U-100 insulin — the concentration used in the U.S. Each syringe is sterile, single-use, and features a fixed 28-gauge, 1/2-inch Micro-Fine needle with a beveled, lubricated point. The permanently attached needle eliminates dead space, so no insulin is wasted, and the fine gauge combined with BD's needle finishing helps make injections noticeably more comfortable for daily users.

A common question buyers ask is how "Lo-Dose" differs from a regular syringe. The distinction is the graduated scale, not the needle — the barrel is marked in single-unit increments across a smaller total volume, which is ideal for children, insulin-sensitive adults, and anyone whose typical dose falls at or below 50 units. If your dosing regularly exceeds that range, a standard 1 mL syringe will suit you better.

Honest Medical stocks the disposable, non-safety Lo-Dose Micro-Fine in the widely reordered 329461 configuration. If you're comparing needle options, the BD Ultra-Fine line offers additional gauge and length choices for insulin delivery. When ordering, confirm your syringe volume matches your prescribed dose and that you're using U-100 insulin to keep unit markings accurate.
