From the Guidelines
The starting dose of Biphentin (methylphenidate) for adults with ADHD is typically 5 mg, given in the morning after breakfast, as recommended by the practice parameter for the use of stimulant medications in the treatment of children, adolescents, and adults 1.
Key Considerations
- The dose can be gradually increased based on individual response and tolerability.
- Morning administration is preferred to avoid sleep disturbances.
- Biphentin works by increasing dopamine and norepinephrine levels in the brain, which helps improve attention, focus, and impulse control in ADHD.
- Patients should be monitored for side effects such as increased heart rate, blood pressure changes, decreased appetite, and insomnia.
- Those with cardiovascular conditions, hypertension, or a history of substance abuse require careful consideration before starting this medication.
Important Administration Instructions
- The controlled-release formulation should be taken whole with water and not crushed or chewed to maintain its extended-release properties.
- Regular follow-up appointments are important to assess effectiveness and adjust dosing as needed.
- The maximum recommended daily dose is not explicitly stated in the provided evidence, but it is generally recommended to use the minimum effective dose to initiate therapy 1.
Monitoring and Follow-up
- Adults on stimulants should have blood pressure and pulse checked on a quarterly basis by the treating physician or by the primary care physician 1.
- Patients should be monitored for treatment-related side effects, and a method of assessing drug response should be decided upon before initiating treatment 1.
