It’s no secret that reduced appetite and weight loss are closely related, and increased appetite and excessive food intake often cause excess weight.
In this article, we will talk about Phentermine and Adderall, the drugs often compared as weight loss pills. Let’s consider their main similarities and differences and find out which is better for you.

It should be noted that you can use both drugs for purposes not mentioned in this review or the package leaflet. Important condition: only a doctor must decide whether you can take prescription drugs, especially CNS stimulants.
Why to compare these drugs if they have different indications?
That is because many people using Adderall report weight loss. Moreover, doctors prescribe drugs containing Amphetamine for obesity (in the USA).
Specifically, Adderall causes:
- loss of appetite in 22% of people;
- loss of weight in 4% of people.
DailyMed provided this information. In this case, reduced appetite and weight loss are adverse reactions. People who underwent ADHD treatment experienced these reactions, and not all of them were on a low-calorie diet and were physically active.
Phentermine to Adderall conversion
Dose conversion coefficients may apply when switching from one drug to another. It is necessary so that you can successfully continue the treatment with the new drug using the optimal dose rather than the starting dose.
Phentermine and Adderall are approved to treat completely different conditions. We found no reliable information on the Phentermine to Adderall conversion coefficients or vice versa.
IMPORTANT INFORMATION!
A doctor must approve and monitor medication or dosage changes.
Conclusion
Adderall and Phentermine are CNS stimulants, but officially they have different indications.
Phentermine is the best solution if your goal is to lose extra kilograms with obesity. It is officially an anorexigenic drug that acts on the centers of appetite in the central nervous system. Adderall may cause weight loss but is not a drug commonly used in the pharmacological treatment of obesity.
Use medicines only for the purpose approved by the pharmacovigilance services and as prescribed by a doctor. Otherwise, do not start treatment.
