An example system for administrating a liquid medication includes a syringe assembly including a barrel portion containing liquid medication, a plunger portion sealingly engaged with the barrel portion to form a chamber for expelling the liquid medication from the barrel portion, and a needle. A ring is positioned about the plunger portion of the syringe assembly, wherein the ring limits movement of the plunger portion in an axial direction as the plunger portion is moved in the axial direction to administer a first dose of the liquid medication. The ring is configured to be modified to allow the plunger to move further in the axial direction to administer a second dose of the liquid medication.
