Why might someone switch from Adderall to Dexedrine?
Individuals may consider switching from Adderall to Dexedrine primarily due to differences in their stimulant profiles and potential side effects. Both medications are amphetamine-based stimulants used to treat attention-deficit/hyperactivity disorder (ADHD), but they contain different combinations of amphetamine salts.
What's in Adderall and Dexedrine?
Adderall is a combination of four amphetamine salts: dextroamphetamine saccharate, amphetamine aspartate, dextroamphetamine sulfate, and amphetamine sulfate [1]. Dexedrine, on the other hand, is composed solely of dextroamphetamine sulfate [1]. This difference means Adderall contains both dextroamphetamine and levoamphetamine, while Dexedrine contains only dextroamphetamine.
How does the amphetamine difference affect people?
The presence of levoamphetamine in Adderall can contribute to a broader stimulant effect, potentially leading to more peripheral side effects like increased heart rate and blood pressure, or a feeling of jitteriness for some individuals [2]. Dexedrine, containing only dextroamphetamine, may offer a more focused or smoother stimulant effect with potentially fewer peripheral side effects for certain patients. A prescriber might recommend switching if a patient experiences intolerable side effects on Adderall that are attributed to the levoamphetamine component, or if they find Dexedrine provides a better therapeutic response for their specific ADHD symptoms.
What are the typical side effects to consider?
Common side effects for both Adderall and Dexedrine can include decreased appetite, insomnia, dry mouth, nausea, weight loss, and anxiety [3]. However, the intensity and specific nature of these side effects can vary between individuals. For instance, some people may find Dexedrine causes less anxiety or sleep disturbance than Adderall, while others might experience the opposite.
When might Dexedrine be a better fit?
Dexedrine is sometimes considered when a patient needs a longer-acting formulation or when a purer dextroamphetamine profile is desired. The decision to switch is highly individualized and based on a patient's response to medication, tolerability of side effects, and the specific symptom profile of their ADHD.
How do these medications differ in terms of formulation and duration?
Both Adderall and Dexedrine are available in immediate-release and extended-release formulations. The extended-release versions are designed to provide symptom control over a longer period, typically 10 to 12 hours. The choice between immediate and extended release depends on a patient's daily schedule and needs for symptom management.
