3 days ago, I received a loading dose of herceptin (alone). I will be taking it weekly. I was given a brochure published by Genentech containing info about Herceptin.
Under "Safety Summary" it said:
"In clinical trails, an infusion-associated symptom complex consisting most commonly of chills and/or fever was observed in approximately 40% of patients during the first infusion. Other side effects may include nausea, vomiting, pain (in some cases at tumor sites), and headache. These symptoms occurred infrequently with subsequent infusions. Overall, there was an increased incidence of anemia, leukopenia, diarrhea, and infection in patients receiving Herceptin in combination with chemotherapy."
Then it went on to dicuss developoment of heart problems.
I normally am more on the constipated side, but after this first dose, I was much more loose than usual, immediately following the treatment. Since then, I have been back to normal.
Hope this helps. I haven't been to this site, but it was listed on the brochure:
