Replacing fluids and various salts in the body is important. This can be done in the hospital or in a clinic if a person cannot keep liquids down. Home treatment is all that is needed in mild cases when nausea and vomiting are not severe. Nausea and the diarrhea may be relieved by certain drugs, such as promethazine or diphenoxylate. These are rarely needed or given, however.
Side effects are uncommon, but any medications given have possible side effects.
Specific side effects depend on the drugs given. People generally recover within 24 hours and feel back to normal within 2 days. A return to normal activities is usually allowed as soon as a person feels better. A doctor will help monitor the disease if a person becomes very ill. If symptoms last for more than 24 hours, medical care should be sought.
