What is the right way to convert Adzenys (amphetamine) to Adderall?
Adzenys ER is an extended-release formulation of amphetamine (mixed amphetamine salts). “Adzenys to Adderall conversion” usually means matching the total milligrams of amphetamine exposure you were getting on Adzenys to a comparable starting dose of Adderall (also mixed amphetamine salts). Exact conversions depend on the specific Adzenys strength you’re on and which Adderall product (immediate-release vs extended-release) your prescriber intends to use.
Because both are amphetamine-based stimulants but come in different release formulations and dosing strengths, conversion should be done by your clinician rather than a simple one-to-one dose swap.
Is there a simple milligram-to-milligram conversion?
Most of the time, there is not a reliable “multiply by X” conversion across all Adzenys strengths and Adderall products. Prescribers typically determine the new dose using:
- The active drug in each medication (mixed amphetamine salts)
- The specific formulation (extended-release vs immediate-release)
- Your current dose response and side effects (blood pressure/heart rate, appetite, sleep, anxiety, etc.)
If you tell me your exact Adzenys strength (for example, “Adzenys XR ___ mg”) and whether you’re switching to Adderall IR or Adderall XR, I can help you narrow down how clinicians usually approach the switch.
What dose changes are commonly made during a switch?
When clinicians switch between amphetamine ER and IR products, they often start cautiously and adjust based on symptom control and tolerability. Changes may include:
- Switching to a lower starting dose if side effects occurred on the current medication
- Moving gradually upward if symptom control was incomplete
- Timing changes to better match when you need medication effects (morning only vs longer coverage)
What should patients watch for after switching?
After any amphetamine formulation change, common issues to monitor include:
- Increased heart rate or blood pressure
- New or worse anxiety, agitation, or irritability
- Reduced appetite or weight changes
- Insomnia or trouble falling asleep
- Stomach upset or headache
- “Rebound” as the medication wears off sooner or lasts too long
If you notice severe chest pain, fainting, hallucinations, or major mood changes, seek urgent medical care.
Can someone convert themselves without a prescriber?
No. Even when drugs are related, formulation differences and individual response make it unsafe to rely on an internet conversion rule. Your prescriber should select the starting dose, then titrate based on your symptoms and side effects.
Quick questions to get you the most accurate conversion guidance
Reply with:
1) Your exact Adzenys product and strength (and whether it’s Adzenys XR)
2) The Adderall product you’re switching to (Adderall IR or Adderall XR)
3) Whether the goal is same-day coverage length or just symptom control
4) Any side effects you had on Adzenys
With those details, I can help you interpret what a typical clinician conversion/titration approach would look like for your situation.
