Holly,
***Zofran is a Class A drug for pregnancies and is perfectly safe to take while breastfeeding. If you are unsure of this, ask your doctor, but it is well studied and known to be safe. The previous poster is mis-informed.***
It sounds like you don't have morning sickness anymore. You have hyperemesis gravidarum. I had this, too and I had the zofran pump. It saved my life and made my life livable. I started on a reglan pump when the oral meds failed, but I had a bad reaction to the reglan, so at 13 weeks they put me on the zofran pump. It literally saved my life. It's weird to wear it all day every day, but you get used to it. They give you a bag so you can take a shower (if you feel up to that, showers make some women feel worse, I puked every time I showered).
Here are some hints:
--Change your infusion sites OFTEN. Like every single time you pop in a new vial. Those sites get saturated and sore and after too long they don't absorb the meds.
--Use a heating pad or ice pack on the sore sites. Zofran is slightly acidic, so it will make hard knots under your skin, but believe me, it's better than the hg.
--Start taking something for constipation. Sorry to be TMI, but that is a side effect of zofran and it can cause more nausea if you don't stay on top of it.
--If the zofran alone doesn't help, don't give up. Zofran will probably stop the vomiting, but some women still experience nausea. If this is the case for you, talk to your doctor about layering in some other meds. During my worst, I was on the zofran pump + oral meclazine and oral benadryl. That did the trick for me.
Go to www.helpher.org (a page dedicated to hyperemesis gravidarum) and click on the forums tab at the top of the page. There is a section there for women in the 2nd trimester. There is even a section about pumps and different things like that in the medication section. This online community was just phenomenal. They really helped get me through when things got really rough.
It sounds like they're setting you up with home IV, too? You mentioned fluids. I really reccomend this. My next pregnancy, I'll be doing this, too. The zofran and other meds work best when you're hydrated. If you can start off hydrated at least, it'll give the zofran a head start to doing its job.
Feel free to message me if you want more info. I'll share everything I can. I've been there. Believe me. I know exactly what you're going through.
