Vyvanse (Lisdexamfetamine) and Adderall (mixed amphetamine salts) are both medications used to treat attention deficit hyperactivity disorder (ADHD) and have different pharmacological properties. Therefore, there is no straightforward one-to-one conversion between the two medications. The equivalent dose of Vyvanse for a specific dose of Adderall can vary depending on the individual and their response to each medication.
Vyvanse is a prodrug, meaning it is inactive until the body metabolizes it into dextroamphetamine and l-lysine. On the other hand, Adderall is a combination of immediate-release dextroamphetamine and amphetamine salts.
As a rough estimate, some studies suggest that 30 mg of Vyvanse may be roughly equivalent to about 8-10 mg of Adderall. However, this conversion can be influenced by various factors, such as an individual's metabolism, age, weight, and overall response to the medications.
It's crucial to determine the appropriate dose of any medication based on a doctor's prescription and under their guidance. If you are considering a change in medication or dosage, please consult your healthcare provider before making any adjustments to ensure a safe and effective treatment plan for your specific needs. They will be able to evaluate your condition and make appropriate recommendations based on your individual circumstances.
