Table of contents:

Symmetrel is an anti-Parkinson and antiviral drug used to prevent or treat symptoms of infection caused by strains of influenza. It can be indicated to treat Parkinson's disease and "Parkinson-like" symptoms such as stiffness or tremors, shaking, and repetitive uncontrolled movements.

Each Symmetrel tablet contains 100 mg amantadine hydrochloride. Amantadine works by blocking the actions of viruses in the body and by restoring the balance of natural substances in the brain. It increases the release of dopamine, a neurotransmitter, and inhibits its reuptake, which helps to reduce the symptoms of Parkinson's disease.

Use and Dosage

Amantadine is taken orally in tablet form either with or without food, as directed by a doctor, typically once or twice a day. If taking it twice daily, take the second dose several hours before bedtime if experiencing trouble sleeping after taking it. Swallow the whole tablet with water, as directed by a doctor. Chewing the tablet may affect its effectiveness and alter its intended release mechanism.

The dosage prescribed is based on a patient's medical condition and their response to the medication, with children's dosage also based on their body weight. Patients should not exceed the recommended dosage as prescribed by their doctor. Taking the tablet at evenly spaced intervals throughout the day and night helps maintain a constant level of medication in the body, maximizing its effectiveness.

Amantadine may take several weeks to show its effects on Parkinson's disease. Patients should not abruptly stop taking the medication as it may worsen symptoms or cause side effects; doctors may gradually reduce doses instead. It may become less effective after several months of use, and patients must inform their doctor if it stops working well.
