Encephalitis - Topic Overview

How is it treated?

If you have encephalitis, you will need to be treated in a hospital. Your treatment will depend on your symptoms and the cause of your illness. You may be treated right away with an antiviral medicine, such as acyclovir. Antiviral medicine may make symptoms less severe, especially if you get the medicine right away. If the doctor thinks that your symptoms are caused by bacteria, rather than by a virus, he or she may treat you with antibiotics.

You will also get care to ease your symptoms and allow your body to heal on its own. This is called supportive care. You may take medicines to reduce pain and fever or to stop seizures. In some cases, you may need a machine called a ventilator to help you breathe.

After you are out of the hospital, it may take several weeks, months, or even longer to fully recover from your symptoms. You can take care of yourself by eating well and getting plenty of rest. Follow your doctor's instructions on how much fluid to drink. If your doctor says it's okay, you can take nonprescription pain relievers for headaches. These include acetaminophen and nonsteroidal anti-inflammatory drugs (NSAIDs) like naproxen, ibuprofen, or aspirin. Do not give aspirin to anyone younger than 20 because of the risk of Reye syndrome. Be safe with medicines. Read and follow all instructions on the label.

Some people have long-term problems. If you have muscle weakness or problems with coordination, you may need physical therapy. If you have speech or memory loss, you may need speech therapy or occupational therapy.
