How can i manage hand foot and mouth disease?

Hydrate...: Hydrate and and give analgesics (acetaminophen or "magic mouthwash"). It goes away by itself regardless of treatment, but it is good to avoid dehydration and mitigate the misery while it does.

Comfort: Popsicles, ice cream, yogurt, other soothing foods, and Ibuprofen or Acetaminophen for pain and fever.

Supportive Care: Hand-foot-mouth disease is typically caused by a virus. Since antibiotics don't work on viruses, the goal is to make the patient as comfortable as possible and to prevent complications like dehydration. Ensuring that the child is drinking fluids and giving them medicine for pain (since it often hurts to swallow) is the best way to manage them.

Soothing: Check with your pediatrician or pcp prior to intaking, but the mix of 1/2 teaspoon of maalox and 1/2 teaspoon of Benadryl (diphenhydramine) coats and soothes the uncomfortable mouth sores.

Depends on variables: Hfm varies more in intensity than anything. Some kids can have it and run a brief temperature and never show other symptoms. Some have fever, localized spots on their wrists & nothing else. Some have terrible mouth sores, spots on wrists/forearms/legs feet / bottom/ have cramping/ loose stools. Fever, loose stools and cramps can lead to dehydration so the focus of therapy is directed at hydration.
