What is Symmetrel (Amantadine Hydrochloride) used for?

Symmetrel (Amantadine Hydrochloride) is used to treat a variety of conditions. It is often prescribed to treat the symptoms of Parkinson's disease, including shaking, and stiffness. It does this by fixing the chemical imbalance in the brain. This can help to make it easier to perform daily tasks. It can also treat these symptoms if caused by certain medications. This drug also works as an antiviral, and is used to prevent and treat influenza A.

How should I use Symmetrel (Amantadine Hydrochloride)?

Symmetrel (Amantadine Hydrochloride) comes in the form of capsules. The dosage required depends on the patient's age, and the condition being treated. Adults up to the age of 65 treating Parkinson's disease are sometimes told to take 1 capsule per day. If there is no improvement in symptoms, your physician may tell you to take 1 capsule twice per day. However, adults over 65 are usually told to only take 1 capsule per day. The dose for adult patients up to 65 years of age treating influenza A is one capsule twice per day. The dosage for children, older adults and patients with a reduced kidney function is less. Therefore, all patients must consult their physician before taking this medication so that the correct dosage can be prescribed.
