Generally, hand, food and mouth disease is treated the same way for adults as for children, with the main differences seen in doses of pain medication. Hand, foot and mouth disease is very rare in adults and children over the age of 10, as most people build up a natural immunity to the disease. However, it is possible to contract the illness at an older age, especially if the adult has a compromised immune system.
In most cases of hand, foot and mouth disease, the condition can heal on its own without any medical intervention needed, according to Healthline. It typically takes about 7 to 10 days for the disease to clear up. However, medications and treatments can be used to alleviate the pain and discomfort associated with the illness.
Pain medication can be used to care for the blisters and rashes that arise from the disease. Headaches and a sore throat are also common with hand, foot and mouth disease, which can also be treated with pain medicines such as acetaminophen and ibuprofen. Other remedies, such as salt water rinses, cough drops, lozenges and medicated syrups, can be used to relieve a sore throat.
It is recommended that if the symptoms do not dissipate after 10 days that the patient consult a doctor, as hand, foot and mouth disease can lead to other illnesses.
