Understanding the 50 mg Vyvanse to Adderall Conversion

If you or someone you know is dealing with ADHD, the chances are that they have been prescribed either Vyvanse or Adderall as part of their treatment plan. These medications are classified as central nervous system (CNS) stimulants and work by increasing the levels of certain neurotransmitters that help with focus and attention.

Understanding the 50 mg Vyvanse to Adderall Conversion

One of the most common questions that arise is how to convert from one medication to another. In this article, we will be focusing on the conversion from 50 mg Vyvanse to Adderall.

The Basics of Medication Conversion

Before diving into specific conversions, it’s essential to understand some basic principles behind medication conversion. First off, different medications have different strengths and potencies. For example, 1 mg of Ritalin may not be equivalent to 1 mg of Adderall due to variations in bioavailability.

Secondly, medication conversion should always be done under close medical supervision. Never attempt to switch medications or change dosages without consulting your healthcare provider first. Your doctor or nurse practitioner will have a thorough understanding of your medical history and can guide you through the process safely.

Lastly, there is no one-size-fits-all when it comes to medication conversion. What works for one person may not work for another due to variations in individual factors such as weight, age, sex, and other underlying conditions.

Understanding 50 mg Vyvanse

Vyvanse (lisdexamfetamine dimesylate) is an amphetamine-based stimulant that is used primarily in ADHD treatment plans. It works by enhancing dopamine and norepinephrine levels within the brain, which leads to improvements in attention and focus.

Vyvanse comes in various strengths ranging from 10 mg up to 70 mg capsules taken once daily orally with water. The maximum recommended dose for adults is 70 mg per day.

Understanding Adderall

Adderall (amphetamine and dextroamphetamine) is another popular medication used in ADHD treatment. It works by stimulating the release of dopamine and norepinephrine, resulting in improved focus, attention, and productivity.

Adderall comes in immediate-release (IR) and extended-release (XR) formulations with a range of dosages available for each. The recommended starting dose for adults is usually between 5-10 mg taken twice daily. The maximum recommended dose is 40 mg per day.

Converting from 50 mg Vyvanse to Adderall

When it comes to converting from one medication to another, there are no hard and fast rules. However, most healthcare providers use a standard conversion ratio to guide their decision-making process.

For example, using the standard conversion ratio of 1:2.5 between Vyvanse and Adderall would mean that 50 mg of Vyvanse is roughly equivalent to 125 mg of Adderall.

However, it’s worth noting that this ratio is not set in stone and may vary based on individual factors such as age, weight, sex, and other underlying medical conditions.

Considerations When Switching Medications

As mentioned earlier in this article, medication switching should always be done under close medical supervision. Your healthcare provider will consider several factors when deciding whether or not to switch you from one medication to another:

  • Current symptoms: If your current medication seems ineffective or has undesirable side effects
  • Medical history: Any pre-existing medical conditions that may affect how well a new medication works or interacts with your current medications
  • Allergies: If you have allergies to any particular medications or ingredients
  • Dosage adjustments: Your healthcare provider may need to adjust the new dosage based on your individual needs.

Potential Side Effects

Switching from one CNS stimulant to another can sometimes result in side effects such as:

  • Headaches
  • Insomnia
  • Mood changes
  • Nausea and vomiting
  • Dizziness

These side effects are usually mild and go away after a few days. However, if you experience any severe or persistent side effects, be sure to contact your healthcare provider right away.


In summary, converting from 50 mg Vyvanse to Adderall is possible but should always be done under the guidance of a medical professional. The standard conversion ratio is 1:2.5, but individual factors may affect the final dosing decision.

When switching medications, it’s essential to have an open and honest dialogue with your healthcare provider about your symptoms, medical history, and any allergies or underlying conditions that may affect treatment.

Remember that medication is just one component of an overall ADHD treatment plan. Be sure to incorporate other strategies such as therapy, exercise, healthy eating habits, and good sleep hygiene into your daily routine for optimal results.
