Abstract: Disclosed are syringes that allow one-handed operation for measuring and dispensing a medicament, provide consistent finger placement on the syringe barrel. The syringes have a generally oval exterior shape that comfortably fits a user's hand and prevents rolling of the syringe when placed on a surface. Due to the shape of the syringes, the dispensing tip will not touch a surface or substrate when the syringe is placed thereon, providing improved hygiene and reduced contamination. The syringes preferably have a dosage marking on the barrel that provides ease of seeing the withdrawn medicament. The dosage marking can be raised and/or colored and/or made light sensitive. The raised markings can provide an audible and/or tactile indication of the dose of medicament drawn into or out of the syringe.
