Welcome to this forum and thanks for posting your query. I believe that the treatment that your doctor has put in place to manage the severe condition such as your hyperemesis gravidarum
is wisely indicated and i suggest you can continue that same treatment except of course you have developed any side effects or complications like phlebitis
linked to the placement of the catheter. Already the IV fluid you are infusing through the PICC line is already helpful in preventing any such complications.
You need to understand that your hyperemesis is a very serious condition that can be both fatal to your health and that of your unborn child, reason why your doctor opted for the PICC line which will ensure proper rehydration. It is safe for your pregnancy. Do keep your doctor on a speed dial in case you develop any abnormal symptoms.
Pepcid is an antacid used to treat gastric ulcers
. There is no danger for your pregnancy.
Hope this helps and reassures you.
