A dosage limiting device is includes an elongated connecting member that has a plunger receiving head at a first end for capturing a plunger flange of a plunger of a syringe. The plunger receiving head has a back flange connected to the elongated connecting member and a forward slotted flange connected to the elongated connecting member, the forward slotted flange is separated from the back flange by a space sufficient to accept the plunger flange and a flat section of the plunger fitting in a slot of the forward slotted flange. A barrel loop is at a distal second end of the elongated connecting member so that the dosage limiting device limits a dosage provided by the syringe based upon a distance between the plunger receiving head and the barrel loop as the barrel loop abuts a barrel flange of the syringe, thereby limiting extraction of the plunger.
