Hello, I have been on phentermine for over a year. I am going to start Adderall because of my A.D.D. The past few months I have only been taking half of the phentermine to be able to focus at work. Do I need to wean off the phentermine then start Adderall or can i just stop phentermine and take Adderall the next day with no withdrawal effects?
This question should be directed to your doctor for confirmation.
Phentermine and Adderall are both central nervous system stimulants similar to amphetamine and even though they are both stimulants they are intended for different purposes. Phentermine is approved for weight loss and Adderall (a combination of amphetamine and dextroamphetamine) is approved to treat ADHD or narcolepsy.
There should be no need to wean off the Phentermine because in essence you are just replacing one CNS stimulant with another (Adderall). There should be no withdrawal effects.
