Precision low-dose, low-waste syringe configurations have a reduced diameter lumen for dispensing 0.01 ml increments of contents. Plunger and lumen configurations and a needle interface eliminate dead space. Ergonomic attachments improve the control and precision of delivery of syringes. An attachment main body includes a gripping surface to permit a user to engage the attachment and move the attachment main body, and thus the syringe plunger relative to the syringe barrel using sliding movement. Optical enhancement features are provided on the attachment to improve the readability of gradations and plunger position. The attachment may be provided with an assist feature, which may be a traction wheel mounted on the attachment body. An alternative configuration suitable for syringe contents of higher viscosity may include a pair of toothed pinion gears on a wheel and which cooperate with respective toothed racks formed on or fastened to the syringe body.

Syringe attachments and syringes have particular suitability to the precision dispensing of small amounts of high viscosity materials, such as dermal fillers. Syringes and attachments may include precision position indicators viewed from multiple positions to enable a user to determine plunger position and the amount of dispensed contents with precision. A configuration of the attachment may be slidably secured to a syringe to permit a user to operate the syringe from a lateral position using sliding movement of the thumb and fingers of one hand, for example. This configuration may be particularly suitable for self-administered insulin injections.
