No problem. I'm glad to share whatever information I have, and I was supported here when I needed help--I'm just paying it forward.
Each dose is supposed to last 6 hours. I have a reactive stomach, which is an ongoing problem that isn't improved with a Nissen. Actually, since the wrap was created out of that same reactive "cloth" it can cause problems as things are forced through it into my stomach. It can get fairly irritable when I have a stretch of eating and drinking things I shouldn't.
Because of this issue I take a dose of Carafate at bedtime (it has to be 2 hours after eating and taking meds and 2 hours before taking meds). I generally wake up in the wee hours, so if it's been nearly 6 hours I take another dose. Most of the time I just take these 2 doses. If I'm having a REALLY bad stomach issue I try to fit at least one more dose in during the course of the day.
I get a 3 month supply and it usually lasts me about 6 months. I can get 1 month free of copay if I get my scripts through a mail-order pharmacy. So it's buy 2 get 1 free.
The hardest part about taking Carafate is getting the doses in between meals and medication. You can eat 1 hour after taking Carafate, but you have to wait 2 hours for meds. If you take meds before Carafate a pharmacist said that you can sneak the Carafate in a little earlier than the 2 hours because it's unlikely that they'll still be in your stomach a full 2 hours. She said, though, that once you take the Carafate, the 2 hour spacing is critical. That's why nighttime works great for me.
If you're getting damage at night (and if it's silent, you'll never know) the nighttime dosing will definitely be helpful, as your esophagus and throat will be protected. Hey, it's worth a try!
Good luck. I'll be interested in hearing if it's helping at all.
Keep in mind that healing takes time.
Have a great day!
