SYMMETREL (Amantadine)

SYMMETREL, known by its generic name amantadine, is a medication primarily used to treat and prevent influenza A virus infections. It is also prescribed for managing symptoms of Parkinson's disease and drug-induced extrapyramidal reactions.

This antiviral agent works by inhibiting the replication of the influenza virus within the body, thus helping to reduce the severity and duration of flu symptoms when taken early in the infection. In Parkinson's disease, SYMMETREL can enhance dopamine release and block the reuptake of dopamine, leading to improved motor control and reduced rigidity.

Some important highlights of SYMMETREL include:

• Indications: Effective for influenza A and Parkinson's disease.


• Mechanism of Action: Works by interfering with the viral replication process and improving dopamine activity in the brain.


• Dosing: Available in capsule and liquid form, with dosing varying based on the condition being treated.


• Side Effects: Common side effects may include nausea, dizziness, insomnia, and dry mouth. More serious side effects can occur and should be reported to a healthcare provider.


• Precautions: Patients with a history of seizures, heart disease, or kidney problems should use this medication with caution.


• Drug Interactions: SYMMETREL may interact with other medications, so it's essential to inform your healthcare provider of all drugs you are taking.

In summary, SYMMETREL is a versatile medication that plays a significant role in treating both viral infections and movement disorders. As with any medication, it is crucial to follow your healthcare provider's guidance for safe and effective use.
