Hand, foot, and mouth disease (HFMD) is a common viral illness that mainly affects young children but can also occur in adults. It causes fever, mouth sores, and a rash on the hands and feet. Since it is caused by a virus, there is no specific cure or antiviral medication for HFMD. Treatment focuses on relieving symptoms, preventing dehydration, and supporting the body as it fights the infection.
The primary goals in treating HFMD are to **ease pain and fever**, **maintain hydration**, and **keep the skin and mouth comfortable**. Here is a detailed explanation of the treatments and care strategies used:
**1. Pain and Fever Relief**
Fever and discomfort from mouth sores can be managed with over-the-counter pain relievers such as acetaminophen (Tylenol) or ibuprofen (Motrin). These medications help reduce fever and soothe muscle aches or mouth pain. It is important to follow dosing instructions carefully based on age and weight. Aspirin should never be given to children due to the risk of Reye syndrome, a rare but serious condition. Topical numbing gels or sprays containing benzocaine or lidocaine are generally discouraged, especially in young children, because they can cause harmful side effects and offer limited relief. Instead, systemic pain relief through oral medications is preferred.
**2. Hydration**
Because mouth sores and throat pain can make swallowing difficult, dehydration is a significant risk. To prevent this, encourage frequent intake of fluids in small amounts. Cold liquids, ice chips, or popsicles can numb the mouth slightly and make drinking easier. Warm broths or soups may also be soothing for some children. Avoid acidic, spicy, salty, or hot beverages and foods, as these can irritate mouth sores and discourage drinking. Oral rehydration solutions can be helpful to replace lost fluids and electrolytes if intake is poor.
**3. Mouth Care and Food Choices**
Soft, bland foods that do not irritate mouth ulcers are best. Examples include yogurt, mashed potatoes, oatmeal, scrambled eggs, and smoothies. Avoid citrus fruits, spicy dishes, salty snacks, and anything crunchy or rough that might aggravate sores. Gentle brushing with a soft toothbrush and mild toothpaste can help keep the mouth clean without causing pain.
**4. Skin and Blister Care**
The rash and blisters on the hands, feet, and sometimes buttocks or genital area should be kept clean and dry. Use gentle soap and water to wash the skin. Avoid popping or scratching blisters, as intact skin reduces the risk of secondary bacterial infection. If a blister breaks, clean the area and cover it with a sterile bandage to protect it. Applying protective ointments like petroleum jelly or zinc oxide can soothe and shield the skin.
**5. Rest and Isolation**
Rest is important to help the immune system fight the virus. Children with HFMD should stay home from school or daycare until fever resolves and mouth sores heal to reduce the risk of spreading the infection to others. Good hand hygiene and disinfecting contaminated surfaces are crucial to prevent transmission.
**6. When to Seek Medical Care**
Most cases of HFMD resolve within 7 to 10 days without complications. However, medical attention is needed if the child or adult shows signs of dehydration (such as very little urine output, dry mouth, or lethargy), has a high or persistent fever, difficulty swallowing, or if symptoms worsen or do not improve. In rare cases, complications like viral meningitis or encephalitis can occur, requiring urgent care.
**What Treatments Are Not Used?**
Antibiotics are ineffective against HFMD because it is caused by viruses, not bacteria. There is no antiviral medication routinely recommended for this illness. Treatment is supportive and symptom-based.
