Dosage: The dose of Concerta that works for your friend might not be the right dose for you. Dosages of ADHD medications are typically individualized based on factors like body weight, metabolism, and individual response to the medication.
Different Conditions: Difficulty with focus and attention can be caused by various factors, not just ADHD. It's possible that your focus issues are related to other factors, such as stress, anxiety, or sleep disturbances.
Incorrect Diagnosis: If you are experiencing trouble with focus, it's essential to get a proper evaluation from a qualified medical professional. Self-diagnosing or relying on medication prescribed for someone else is not safe or effective. Only a healthcare professional can accurately diagnose ADHD or any other condition that may affect focus and attention.
Placebo Effect: Sometimes, the belief that a medication will work can lead to a perceived improvement, even if the actual drug has no pharmacological effect. This is known as the placebo effect, and it can influence how individuals perceive the impact of a substance.
Tolerance: Your friend might have developed tolerance to the effects of the medication over time, making the 18mg dose less effective for them.
Individual Differences: People can respond differently to medications due to genetic, biological, and environmental factors. What works for one person may not work for another.
If you are experiencing difficulties with focus or attention, it's essential to consult a healthcare professional for a proper evaluation and diagnosis. They can help determine the underlying cause of your issues and recommend appropriate treatments, which may or may not include medication.
Remember, sharing prescription medications with others is not safe and can be illegal. Medications like Concerta should only be used under the supervision and prescription of a qualified healthcare provider who can monitor your response and adjust the dosage as needed.
