Get StartedTreatments and drugs
By Mayo Clinic staffThere's often no specific medical treatment for viral gastroenteritis. Antibiotics aren't effective against viruses, and overusing them can contribute to the development of antibiotic-resistant strains of bacteria. Treatment consists of self-care steps.
To help keep yourself more comfortable and prevent dehydration while you recover, try the following:
- Let your stomach settle. Stop eating and drinking for a few hours.
- Try sucking on ice chips or taking small sips of water. You might also try drinking clear soda, such as 7UP or Sprite; clear broths; or noncaffeinated sports drinks, such as Gatorade. Affected adults should try to drink plenty of liquid every day, taking small, frequent sips.
- Ease back into eating. Gradually begin to eat bland, easy-to-digest foods such as soda crackers, toast, gelatin, bananas, rice and chicken. Stop eating if your nausea returns.
- Avoid certain foods and substances until you feel better. These include dairy products, caffeine, alcohol, nicotine, and fatty or highly seasoned foods.
- Get plenty of rest. The illness and dehydration may have made you weak and tired.
- Be cautious with medications. Use medications such as ibuprofen (Advil, Motrin, others) sparingly, if at all. They can make your stomach more upset. Use acetaminophen (Tylenol, others) cautiously. It sometimes can cause liver toxicity, especially in children.
When your child has an intestinal infection, the most important goal is to replace lost fluids and salts. These suggestions may help:
- Help your child rehydrate. Give your child an oral rehydration solution such as Pedialyte. Don't use water — in children with gastroenteritis, water isn't absorbed well and won't adequately replace lost electrolytes. You can find oral rehydration solutions in most grocery stores. Talk to your doctor if you have questions about how to use them. Avoid giving your child apple juice for rehydration — it can make diarrhea worse.
- Get back to a normal diet slowly. Gradually introduce bland, easy-to-digest foods, such as toast, rice, bananas and potatoes.
- Avoid certain foods. Don't give your child dairy products and sugary foods, such as ice cream, sodas and candy. These can make diarrhea worse.
- Make sure your child gets plenty of rest. The illness and dehydration may have made your child weak and tired.
- Don't give children or teenagers aspirin. It may cause Reye's syndrome, a rare, but potentially fatal, disease. Avoid giving your child over-the-counter anti-diarrheal medications such as Imodium unless advised by your doctor. They can make it harder for your child's body to eliminate the virus.
If you have a sick infant, let your baby's stomach rest for 15 to 20 minutes after vomiting or a bout of diarrhea, then offer small amounts of liquid. If you're breast-feeding, let your baby nurse. If your baby is bottle-fed, offer a small amount of an oral rehydration solution or regular formula. Don't dilute your baby's formula.
