When and How to Take Herceptin

Some general considerations for when and how to take the medication include the following:
  • It is given intravenously (by IV) every seven days or every three weeks (depending on the dosing regimen).
  • Your first Herceptin infusion will last 90 minutes, and subsequent infusions may be shorter (depending on the dosing regimen).
  • Most people receive their infusion at their healthcare provider's office, a hospital, or at an "infusion center."
  • For the medication to work properly, it must be taken as prescribed. Herceptin will not work as well if you stop taking it before your healthcare provider recommends.

Dosing Information

The dosage that your healthcare provider recommends will vary, depending on a number of factors, including:
  • The type of cancer (breast or stomach)
  • The severity of your breast cancer (see Breast Cancer Stages)
  • Your weight
  • Other medications you may be taking
  • Other medical conditions you may have.
As is always the case, do not adjust your dose unless your healthcare provider specifically instructs you to do so.
