Side Effects

Leakage of crystalloids around the vein (i.e. from a poorly-placed or dislodged IV catheter) may cause irritation. Inflammation and/or infection of the vein are known risks of IV catheter placement. Inappropriate crystalloid selection may cause electrolyte imbalances.

Precautions

Intravenous or subcutaneous administration of crystalloid solutions must be done with strict attention to proper sterile technique.

Dosage should be calculated and monitored by a licensed veterinarian.

Interactions

Certain drugs (i.e. flunixin meglumine) will form precipitates when mixed with particular crystalloids such as Lactated Ringer's solution. Addition of medications to IV crystalloid fluid solutions should not be performed except under the direct supervision of a licensed veterinarian..

Overdose

Excessive IV fluid therapy can cause symptoms of volume overload, including pleural effusion (build-up of fluid in the chest cavity). Smaller animals are particularly vulnerable. Dosing should be calculated and monitored by a veterinarian
