1. Understanding Vyvanse and Adderall
Vyvanse (lisdexamfetamine) and Adderall (amphetamine/dextroamphetamine) are both central nervous system (CNS) stimulants prescribed for the treatment of attention-deficit/hyperactivity disorder (ADHD). While they share the common goal of increasing focus and attention, they differ significantly in their composition, how they are metabolized by the body, and their duration of action.
- Vyvanse: This medication contains lisdexamfetamine, which is a prodrug. This means it’s inactive until it’s converted into dextroamphetamine by the body.
- Adderall: This medication is a combination of amphetamine and dextroamphetamine salts. It comes in two forms: immediate-release (IR) and extended-release (XR).
1.1. Key Differences Between Vyvanse and Adderall
| Feature | Vyvanse (Lisdexamfetamine) | Adderall (Amphetamine/Dextroamphetamine) |
|---|---|---|
| Active Ingredient | Lisdexamfetamine (prodrug, converted to dextroamphetamine) | Amphetamine and Dextroamphetamine Salts |
| Type | Prodrug | Active Drug |
| Forms | Oral Capsule, Chewable Tablet | Immediate-Release (IR) Tablet, Extended-Release (XR) Capsule |
| Metabolism | Converted to dextroamphetamine in the body | Directly affects dopamine and norepinephrine levels |
| Duration | Up to 14 hours | IR: 4-6 hours, XR: Up to 12 hours |
| Approved Uses | ADHD (adults and children 6+), Binge Eating Disorder (adults) | ADHD (adults and children 3+), Narcolepsy (adults and children 6+) |
| Potential for Abuse | Lower due to prodrug nature | Higher due to direct action |
| Dosing | Once daily in the morning | IR: 1-3 times daily, XR: Once daily in the morning |
| Side Effects | Similar, but Vyvanse may have fewer intolerable side effects | Similar, with potential for more pronounced side effects in some individuals |
| Generic Available | Yes | Yes |

2. What is the Equivalence of 60 mg of Vyvanse to Adderall?
Determining the equivalent dosage between Vyvanse and Adderall is not a straightforward calculation because of the way each drug is processed in the body. However, we can provide a general comparison based on clinical experience and available literature.
2.1. Understanding the Dosage Conversion
- Vyvanse (Lisdexamfetamine): Since Vyvanse is a prodrug, it needs to be converted into dextroamphetamine in the body. This conversion process means that not all of the ingested Vyvanse becomes active dextroamphetamine.
- Adderall (Amphetamine/Dextroamphetamine): Adderall contains both amphetamine and dextroamphetamine salts, which directly affect neurotransmitter levels in the brain.
2.2. General Dosage Comparisons
As a reference, consider the following dosage comparisons:
- 30 mg of Vyvanse: Approximately equivalent to 10 mg of Adderall XR or 7.5-10 mg of Adderall IR (divided doses).
- 50 mg of Vyvanse: Approximately equivalent to 15 mg of Adderall XR or 12.5-15 mg of Adderall IR (divided doses).
- 70 mg of Vyvanse: Approximately equivalent to 20 mg of Adderall XR or 17.5-20 mg of Adderall IR (divided doses).
Given these ranges, we can estimate the equivalent of 60 mg of Vyvanse in terms of Adderall.
2.3. Estimated Equivalent of 60 mg Vyvanse to Adderall
60 mg of Vyvanse is roughly equivalent to:
- Adderall XR: Approximately 17.5 mg to 20 mg.
- Adderall IR: Approximately 15 mg to 17.5 mg, divided into two or three doses throughout the day.
Disclaimer: These are approximate conversions. It’s crucial to consult with a healthcare provider for personalized dosage recommendations.
2.4. Why Conversion Isn’t Exact
The conversion between Vyvanse and Adderall dosages isn’t an exact science due to:
- Individual Metabolism: People metabolize drugs at different rates, affecting how much of the active drug is available.
