You're welcome, Im glad you found the info helpful

We're all in this together and learn from each other.
Feeding tubes can be a bit of a pain but for many they are a necessity. Ive used one for most of the past 11 years. Often patients do not get enough instruction to easily manage the feeding tubes. I know I'll be able to help you with info when the time comes. Most often if there's nausea of the patient is having trouble tolerating the formula its usually fixed when they slow down their feeding rate and/or add some water. Most patients detest having to depend on a feeding tube... so do I! But it is what it is

Make sure whoever arranges for the feeding tube formula and supplies to get delivered, they also send a visiting nurse to set it up and show the patient how to use everything. You and any other caregivers should be there and see what the nurse does and says so you can help your father down the road. Make sure your father gets a feeding pump too, some patients must ask their doc to get this. I find it very easy to do feedings while watching tv or even overnight while I sleep thats why the pump is so important. Sorry for giving you TMI. When the time comes let me know if you guys need help.
Since your father will have a feeding tube then the centrum can be given right thru the tube. It can even be added to the formula. Just check it with his doc if its ok to use. You'd be surprised at the things that can interfere with treatments or cause issues for the patient.
