What is a potential outcome of injecting a physically incompatible drug?

Injecting a physically incompatible drug can lead to adverse reactions or ineffectiveness, which is a significant concern in compounding sterile preparations. When two drugs are incompatible, they may interact chemically or physically, leading to precipitation, cloudiness, or even a complete lack of efficacy. Such interactions can result in harmful effects for the patient, including allergic reactions, toxicity, or therapeutic failure.

Understanding drug compatibility is critical for compounding sterile preparations to ensure patient safety, enhance therapeutic effectiveness, and minimize the risk of complications related to injection. This knowledge helps technicians avoid combinations that could compromise the integrity of the medication and the health of the patient.
