I asked my onc!

Priscilla,
Yesterday I checked with my Onc. He said Herceptin is either given WEEKLY or EVERY THREE WEEKS. I guess the half-life is 1 and 1/2 weeks.?. He said if there are no other physical reasons, that skipping a week just wasn't in the literature/study results to do. (That wasn't exactly what he said, but I'll leave it at that.LOL)

Love and light,

Lisa

My onc said the same thing, as Lisa's onc did. Weekly or every 3 weeks.

I'm on weekly herceptin for up to 1 year ('til Aug '04). Going to Mexico on vacation with hubby for 1 week next month, thus missing my weekly date. Onc rescheduled for me on 3 week dosage just before my vacation. I'll resume weekly, thereafter.

This will be my first 3 week dosage. Anyone experienced both dosages? Feel any difference? Side effects? So far, I haven't gotten any side effects from herceptin.
