Are there alternative routes for trastuzumab administration?

What other routes can trastuzumab be given through besides IV infusion?

Trastuzumab is commonly given by intravenous (IV) infusion, but there are alternative administration routes depending on the product and treatment setting. The provided information specifically confirms that trastuzumab can be administered as an IV infusion and also as a subcutaneous injection [1].

How does the subcutaneous option compare with IV?

The subcutaneous formulation is an alternative route designed for administration by injection rather than IV infusion [1]. The key practical difference is the route (under the skin vs. into a vein). Choice between routes typically depends on the specific trastuzumab product available and clinical context, since the information here only establishes that both routes exist [1].

Are there additional non-injection routes (oral, intramuscular, etc.)?

The provided information only supports two administration routes: IV infusion and subcutaneous injection [1]. No other routes are listed in the provided material.

What should patients ask their care team when choosing a route?

Because the only documented alternatives here are IV and subcutaneous, the most relevant decision points to ask about are whether the subcutaneous version is appropriate for the patient’s regimen and whether the care site can administer it [1].
