she should see her medical provider or at least have a phone consultation. there are effective medications to help control vomiting but they require a prescription (i don't know that age of your daughter). in the meantime make sure that she takes frequent sips of water or other electrolyte solutions so that she will not become dehydrated.
my daughter started vomiting 6 hours ago 8 times. she even woke up to vomit. fever 100. 8. what should i do? . she can not keep anything down.
