From the Guidelines
Foquest and Vyvanse are both stimulant medications used to treat ADHD, but they differ in their active ingredients, duration of action, and side effect profiles, with Foquest containing methylphenidate and Vyvanse containing lisdexamfetamine, a prodrug that converts to dextroamphetamine in the body. The primary difference between these two medications lies in their mechanism of action, with methylphenidate (Foquest) primarily blocking dopamine reuptake, and lisdexamfetamine (Vyvanse) increasing dopamine release and blocking reuptake 1. This distinction is crucial as it may influence the response of individual patients to either medication.
Key Differences
- Duration of Action: Foquest has a controlled-release formulation lasting up to 16 hours, while Vyvanse typically lasts 10-14 hours.
- Abuse Potential: Vyvanse has a lower abuse potential due to its prodrug formulation, which requires metabolic activation in the body.
- Dosage: Foquest is available in dosages ranging from 25mg to 100mg, and Vyvanse dosages range from 10mg to 70mg.
- Side Effects: Both medications have similar side effect profiles, including potential appetite suppression, sleep disturbances, and cardiovascular effects, though individual responses can vary.
Clinical Considerations
When choosing between Foquest and Vyvanse, factors such as previous medication response, duration of coverage needed, side effect tolerance, and individual metabolism should be considered 1. It's also important to monitor patients for signs of tolerance and side effects, especially when prescribing higher doses. The decision should prioritize minimizing morbidity, mortality, and maximizing quality of life for the patient, taking into account the latest evidence on stimulant medications for ADHD treatment 1.
Monitoring and Titration
Clinical guidelines recommend monitoring pulse, blood pressure, height, and weight when prescribing psychostimulant medication, due to potential effects on these parameters 1. Titration should be done carefully, considering the patient's response and side effects, with the goal of achieving the best possible control of ADHD symptoms while minimizing adverse effects.

From the Research
Difference between Foquest and Vyvanse
- There is no direct comparison between Foquest and Vyvanse in the provided studies, as Foquest is not mentioned in any of the studies.
- However, Vyvanse, which is another name for lisdexamfetamine dimesylate, is discussed in several studies as a treatment for Attention Deficit Hyperactivity Disorder (ADHD) 2, 3, 4, 5, 6.
- Lisdexamfetamine dimesylate, or Vyvanse, is a long-acting amphetamine prodrug that has been shown to be effective in treating ADHD in children, adolescents, and adults 2, 3, 4, 5, 6.
- The studies suggest that Vyvanse has a low abuse and diversion potential, and is generally well-tolerated, with common side effects including appetite suppression, weight loss, headache, and insomnia 3, 4, 5, 6.
Efficacy of Vyvanse
- The studies demonstrate that Vyvanse is effective in reducing ADHD symptoms and improving overall quality of life in children, adolescents, and adults 2, 3, 4, 5, 6.
- A meta-analysis of randomized, double-blind, placebo-controlled trials found that Vyvanse had a high effect size in reducing ADHD symptoms, compared to placebo 5.
- Another meta-analysis found that Vyvanse effectively alleviates the symptoms outlined by the ADHD-RS-IV scale, with no differences in the individual subscales or in the safety profile 6.
Comparison to Other Treatments
- The studies compare Vyvanse to other treatments for ADHD, including methylphenidate, atomoxetine, and modafinil 2, 3, 5.
- The results suggest that Vyvanse is a useful alternative option for the treatment of adults with ADHD, including those who have not responded adequately to previous ADHD therapies 2.
- A head-to-head comparison of Vyvanse and other long-acting agents, such as methylphenidate and atomoxetine, is lacking, but the available data suggest that Vyvanse has a promising potential for treating adults with ADHD 2, 5.
