Lactated Ringer's solution is a solution that is isotonic with blood and intended for intravenous administration. It may also be given subcutaneously. Lactated Ringer's solution is grouped with intravenous fluids known as "crystalloids" – which include saline and dextrose solutions (compared to the "colloids" which contain larger molecules such as starch or gelatine).
Lactated Ringer's solution is abbreviated as "LR", "RL" or "LRS".

It is very similar, though not identical to, Hartmann's solution, which is more commonly found in British and Irish hospitals and has slightly different ionic concentrations.
