Which drug is known to crystallize when administered intravenously with D5S?

The drug that is known to crystallize when administered intravenously with D5S (5% dextrose in saline) is Dilantin, also known as phenytoin. When Dilantin is mixed with D5S, it can lead to precipitation due to its low solubility in that particular solution. This crystallization can pose risks, such as thrombophlebitis and embolism, if the crystallized particles are infused into the bloodstream.

Other medications listed may have their own compatibility issues with various intravenous solutions, but they do not specifically crystallize with D5S in the same manner as Dilantin. Understanding these compatibility issues is critical in clinical settings to ensure patient safety and optimize drug administration.
