Anyone get acid on Herceptin?

If by "acid" you mean acid indigestion or heartburn, yes, I've had some of that. But I'm not sure if it's from the Herception or the chemo (I'm on TCH). Usually Tums or another OTC remedy works fine.

Moonwolf.....I had terrible acid reflux and trouble swallowing food while I was on FEC.  While I had many severe side effects during Taxotere and Herceptin, this was not one of them.  However, since I have been on Herceptin only, new acid problems have started.  It's not really acid reflux and swallowing is not an issue but it's pain that is occuring at top of my stomach, right under the middle of my rib cage.  My family doctor checked my out last week and when she pressed on that spot I jumped and screamed......she believes it's acid issues and told me to take a double dose of Zantac daily for one week, then switch to the regular dose for the following week and see if this gets better.  So far it hasn't changed and now I am experiencing a little nausea at times too......will keep you posted.  Have you seen your doctor about this?    

Thanks Moonwolf.....acid issues haven't changed much since my last post and I've been on Zantac for a week.  Will give it one more week and then I'm going off of it as I don't like taking these things either.  I know chemo attacks fast growing cells, thus the hair loss, mouth issues, etc.....I believe I read that stomach lining is included here, so maybe your onc is right and it just takes time for everything to get back to normal.  I guess like everything else, we just have to wait and see.  Cheers to our new level of required patience .........all the best!!  

I have had stomach issues all through treatment,I stopped chemo the last of January and am on Herceptin only, stoamch issues continue.My doctor prescribed carafate,it does wonders and has very few side effects.I notice a huge difference if I stop taking it.I could not take any of the anti acids,due to the rebound affect and they also diminish certain vitamins and minerals that need acid to be utilised. I also take DGL licorice.Jackie

I had gastrits so bad I was in the hospital,they did an endoscope and my onc said my stomach(actually my duodenum) looked like a pepperoni pizza,sorry,don't mean to spoil pizza for anyone! I started on the carafate three times a day and my stomach felt so much better in a few weeks, of course, being averse to meds I stopped taking it.My stomach flared again and onc said to take it at least once a day while I am still on herceptin and for a while after as the herceptin takes so long to leave the system.I take it late at night. I lost over 30 pounds during chemo,I was not able to eat because of the stomach pain and queasiness.My stomach is one of my weak spots.The carafate has much fewer side effects than the anti acids, they really screw up absorption of B viramins and others.The thing is if your digestive tract is inflamed, that affects the absorption of everything,so it needs to be healed.I am eating good now and have gained back some of the weight.Without the carafate I have large bulky stools, when I take it,they are  normal.I also have more energy,I think because I am getting my food digested better.Jackie

That is OK, I have not checked in here in a few weeks.My stomach got bad after only two chemos,but it  continued while on just  herceptin if I stopped the carafate...had my last herceptin October 1!!! I am still taking the carafate and my stomach is so much better,I am eating like a pig..I still remember not being able to eat,so I enjoy every bite.

I had terrible heartburn and acid reflux on TCH. I tried Tums, but they were useless.  My oncologist put me on Nexium while I was on chemo and I would take one pill each day for the first few days after a treatment and it was much better.  Once I finished the chemotherapy, the acid reflux went away.  I didn't feel it at all when I was on Herceptin only.
