Neratinib for Breast Cancer, Adjuvant "The jury is still out for me on this new adjuvant treatment. I finished Herceptin and Perjeta on June 28th and started Nerlynx July 7. The first 24 hours were manageable with diarrhea, but we’ve been off to the races since then. 12-15 times a day in the restroom. I’m taking the prescription strength Imodium per the directions, but I see many here take it every two hours. I’m calling the oncologist today to ask if I can take it that frequently because if not, I will have to stop taking Nerlynx. It is disrupting my life, and the nausea and belching aren’t helping either."

Neratinib for Breast Cancer, Adjuvant "Was determined to continue with Nerlynx despite severe diarrhea, nausea, vomiting, and total loss of appetite. Most side effects stopped at the three-month mark, thankfully. Lost 10 kg in that three months (needed to lose weight)."

Neratinib for Breast Cancer, Adjuvant "I have taken Nerlynx (Neratinib) for 1 week. Today, the 7th day, I'm going back to the Imodium every 6 hrs. Within the first 8 hours, my stomach was cramping, diarrhea, and nauseous. After the 3rd day of diarrhea more than 15 times a day, my oncologist increased the Imodium to every 2 hours. I'm still tired but have high hopes in continuing for the full 12 months."

For Breast Cancer, Adjuvant "I started this drug, neratinib, in February of 2019. Of course, I had the same issues with diarrhea like everyone and went on a strict course of three doses a day of two each Imodium. The first two months were terrible, and I could not really find anything online to help. In the third to fifth months, the diarrhea was almost gone, and that was a blessing. From July to now, which is October 2019, the diarrhea has returned with a vengeance. My oncologist told me that most of his patients have stopped taking it. I am going to stick it out because I trust him, and if this helps me, then it will be worth it. I actually gained weight! I feel pretty lousy most every day, like I have the flu, and I get skitzed out that it might be more cancer because I do worry. I am nauseated a lot, so I seem to eat more. I am tired of cleaning my toilets...that is for sure!"
