Capecitabine side effects are really tough: What helps?

I’ll be finishing my 1st week today. I spoke to the dietician yesterday and a low fiber diet is recommended for me. I have GERD so I switched to Famotidine 40mg because of heartburn issues. I have Prochlorperaz for nausea which I haven’t had to use yet.
I feel good so far but she said to expect it to change a bit going into the 3rd week and beyond. Possible skin issues which I’ll keep an eye on.
Thank you for checking on me 🙏🏼

@gc4217 I used zofran initially. It helped. I eased my way off it eventually, but it can be hard to stop the nausea train once it starts.

@115 Good for you for tolerating it well so far. It's even better that you are prepared for any bumps in the road should they come. Preparation helps to maintain any mental and emotional side effects that happen during the battle. How do you typically manage stressful situations? How do you relax?

@tomrennie did you start it before nausea symptoms or when you started having them. Doctors told me to only use when needed but I have seen so many using it before your nausea kicked in. How did you go about easing yourself off. Did the nausea stop?

@gc4217 I took it right from the start. I was already very sick. After my chemo med temozolomide was stopped and my capecitabine was reduced to 2000mg a day, I reduced zofran by taking one day off, then two days off, and so on. I eventually switched to a scopolamine patches, frequently used for motion sickness, for about six months. I then stopped nausea meds altogether. I still get nausea occasionally, but it usually comes with hunger. I eat something, then it subsidies.

Thank you all for your input. I just started taking Capecitabine this past Monday for the first time. Today is day 7 and I started noticing being fatigued and slight body aches. There have been a couple days this past week where I couldn’t sleep. I am on 3000mg per day. We will see how I feel in week 2. Not looking forward to adding temozolomide on day 10.

I was diagnosed with stage 4 colon cancer in December of 2022. I started systemic chemotherapy in February of 2023. My Cea numbers were initially in the 45 range but after about 6 months of chemotherapy they got down to the single digits. The cancer responded very well to the chemo and in 2025 I asked the Dr if I could try the pills. He agreed and put me on capecitabine. There were side effects. Primarily tiredness and my hands began to dry out and crack. Feet also. Was told this was hand and foot syndrome which was common. Diarrhea but that has been common since they removed my cecal valve when removing the tumor in 2022. Last quarter of 2025 my cea numbers began to climb. Had a PET Scan in December and they found that a lymph node along my back was now involved.
Point is that I read now that cancer can develop a resistance to capecitabine. Apparently there are some chemicals that you can get with systemic chemotherapy that can’t be given while you're on capecitabine. You don’t say what you were doing before capecitabine or your type of cancer. May want to address this with you Dr. Good luck!

@iverwig If I recall correctly, you had extensive surgery not that long ago correct? You have had a lot going on. Are your CAPTEM cycles two weeks on with temozolomide on days 10-14 and two weeks off?

@115 week 2 how are you doing. They canceled my treatments this week waiting on a biopsy result before they start. Hoping you are doing ok.

@tomrennie yes, I had an extensive surgery back in 2023 and had a reoccurrence in 2025. In reference to the CAPTEM I am on the 2 week cycle with the temozolomide on days 10-14 as you mentioned. I start the temozolomide tomorrow as it will be day 10 for me.
