What is the maximum volume that can be administered intradermally?

The maximum volume that can be administered intradermally is typically between 0.01 mL and 0.5 mL. This method of injection is designed to introduce a small amount of medication just beneath the surface of the skin, allowing for localized effects, such as in the case of allergy testing or vaccinations like the tuberculin skin test.

Intradermal injections require precision, as they place the medication within the dermal layer, which is delicate and can only accommodate a limited volume without causing complications, such as swelling or discomfort. Administering too much fluid intradermally can lead to various issues, including poor absorption or adverse reactions in the tissue.

Other options present volumes that exceed the commonly accepted maximum for intradermal administration, which is why they are not suitable choices for this administration route. Understanding the specific volume limits is essential for safe and effective medication practices.
