Is pedialyte good for adults?

Tasty for kids. If you can tolerate the taste, its fine.
Expensive for effect. Pedialyte is designed for infants and small children with specific metabolic needs during vomiting or diarrhea.For adults, it poses no risk. You can get a similar benefit with half strength Gateraid.
Pedialyte: Adults? Yes. I have a lot of patients who when they were sick chose this product to help they stay hydrated...There are even some products that try to play on this for adults.
