Okay, I am back. I suspect that we are dealing with acute gastritis. I think that we can manage this at home. But, if the signs do not resolve, an examination would be in order.
Let’s give Pepcid AC at 1 X 10mg tablet per 20 pounds twice daily. This is Famotidine and it decreases the acid in the stomach.
Just put on the finger's tip and place it on the back of the tongue, then hold the mouth closed till swallows.
You can offer Pedialyte, or water to drink starting 2 hours after the first dose. Flavored and Unflavored Pedialyte are both fine.
I would not offer any food until later tonight.
Then, please feed cooked hamburger and rice. Use lean ground beef and strain off the fat before mixing it with the cooked rice. I would feed 3X daily.
Watch for vomiting or continued vomiting, not eating, blood in vomit.
Normally I like clients to continue with this treatment regimen for two days.
