SIDE EFFECTS: Dry lips and mouth, minor swelling of the eyelids or lips, crusty skin, nosebleeds, upset stomach, or thinning of hair may occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.
Duration of stomach flu depends on the severity of the attack. The condition may become worse in case of infants, young children and elderly who cannot drink sufficient fluids to compensate for dehydration experienced during the illness. For these people, stomach flu can last for 3 weeks or more.
How long does it take to catch the stomach flu - If I was around someone who had the stomach flu 3 days ago, how long would it take for me to catch it. I'm so scared? Norovirus. If this is norovirus (one of the more common causes of gastroenteritis) the incubation period is 24-48 hrs. Hope you don't get this.
