What is a disadvantage of intravenous (IV) drug administration?

Intravenous (IV) drug administration allows for rapid delivery of medication directly into the bloodstream, leading to immediate pharmacological effects. However, one notable disadvantage is that it typically requires continuous monitoring of the patient’s condition and vigilance by healthcare providers. This is essential because IV administration can lead to complications such as infection, phlebitis, or adverse reactions that may develop suddenly. Continuous monitoring ensures any potential issues can be identified and addressed swiftly.

While high bioavailability and immediate onset of drug action are advantages, they also mean that once the drug is administered, there is little that can be done to reverse its effects, highlighting the need for patient vigilance. Moreover, the ability to adjust the flow rate is indeed an advantage, allowing healthcare providers to tailor the medication delivery according to the patient's needs. Thus, the requirement for patient vigilance in IV administration is a significant consideration that underscores the need for careful management in this route of drug delivery.
