Why is this medication prescribed?

Osmolex ER (amantadine extended-release) is a medication prescribed for the treatment of Parkinson’s disease and certain movement disorders. It is also used as an adjunctive treatment for patients with Parkinson’s disease who experience “off” episodes, which are periods of decreased movement or mobility.

The active ingredient in Osmolex ER, amantadine, is an antiviral and antiparkinsonian agent. It works by increasing the levels of dopamine in the brain, which helps to improve motor control and reduce symptoms such as tremors, stiffness, and slowness of movement associated with Parkinson’s disease.

Osmolex ER is an extended-release formulation, meaning that it releases the medication slowly over time, providing a continuous and stable therapeutic effect throughout the day. This can help to maintain a consistent level of medication in the body, reducing fluctuations in symptoms and optimizing control of Parkinson’s disease.

It’s important to note that Osmolex ER should be used under the supervision of a healthcare professional who can determine the appropriate dosage and monitor its effectiveness and any potential side effects.

How should this medicine be used?

Osmolex ER (amantadine extended-release) should be used exactly as prescribed by your healthcare professional. It is important to follow the instructions provided on the prescription label and to consult your doctor or pharmacist if you have any questions.

Here are some general guidelines for using Osmolex ER:

  • Dosage: The recommended starting dose for Osmolex ER is usually 129 mg taken orally once daily in the morning. Your doctor may adjust the dosage based on your individual needs and response to the medication.
  • Swallow whole: Osmolex ER tablets should be swallowed whole and should not be crushed, chewed, or divided. Breaking the tablet can disrupt the extended-release mechanism and affect the medication’s effectiveness.
  • Timing: Osmolex ER is typically taken in the morning with or without food. Taking it early in the day can help minimize potential sleep disturbances, as it may cause insomnia or other sleep-related side effects if taken later in the day.
  • Duration: Osmolex ER is designed to provide continuous release of medication throughout the day. It is important to take it at the same time each day to maintain a consistent level in your body and optimize its effects.
  • Follow-up: Regularly follow up with your healthcare professional to monitor your response to Osmolex ER and make any necessary adjustments to your dosage or treatment plan.

Remember, these are general guidelines, and it’s essential to follow the specific instructions provided by your healthcare professional. If you have any concerns or questions about the use of Osmolex ER, reach out to your doctor or pharmacist for clarification.
