I confirm fully the comments of Chromophobia
While dextroamphetamine may provide you with temporary relief from depression, the side effects it carries will not allow you to treat your depression in a sustainable fashion. As your tolerance grows so will the dose, and the side effects will inevitably increase. Another thing to keep in mind is even though amphetamines are prescribed off-label for depression, many users tend to develop depression after chronic long term use. If you suspect dopamine to be the cause of your depression, I would recommend bupropion.
You take mixed-salts-amphetamine (Adderall) for your ADHD, since your asking this question I would assume that you think dextroamphetamine would be able to tackle to your depression were Adderall couldn't, but I don't think it would make much a difference.
I am brand new to this Forum. I feel I should limit my comments, until, I get used to the rules. I can say, that, I have been taking stimulants, for
19 years in a row, all legally prescribed, by 4 DX's all for ADD, in this order, first Ritalin 60mg, then ten years of combination Dexedrine Spansule 15mg
+ Adderall 10mg x 2, the past 3 years, my current psychiatrist of 13 years, has cut me down to a max dose of 3 x 10 mg of original I/R Adderall only.
All of my psychiatrists, since 1994, have from time to time, titrated in "Wellbutrin" from 30 days to 90 days in addition to my stimulants, and the side
effects, (were not acceptable to me) also have titrated in most SSRIs's and SNRI's, and light dose Tri-cycle anti-depressants, even anti-hypertensives.
I will only say, that I feel at 19 years of use with only 3 breaks, of 3 days, 15 days, and 17 days, I got worse, when I stopped....thus I started back up
on the prescriptions of mostly d-amphetamine or, now, the amphetamines salts (generic Adderall) and as the moderator said, "many users tend to develop
depression after chronic long term use" That is me!!! Frankly I feel I have been depressed all of my life, but, the DX of A.D.D. was highly rewarding to me
for maybe the first 5 years, in material success, two college degrees, and one marriage, and career success, as I "could focus" yet in the long run, it has
worked against me, I have lost most of my social friends, due to my self absorbed personality, and my inability, to control my impulsive talking, for one
thing, and, as I age, my abnormal keen interests in a number of uncommon subject areas of life, just bore new well intended acquaintences, fast.
My most up to date Dx is A.D.D inattentive type, Mood Disorder (Not otherwise specified) and, Obsessive Compulsive Anxiety Disorder. Finally, I have had
nine years (9) years yes, of individual psychotherapy, from three Ph.D's and 3 more MSW's of both genders, in addition, to med management, and 25 years
in AA, that I resigned after my unexpected Divorce, that seems to have crippled me since 2007. I am a middle aged male, who did not get the ADD Dx until
I was 43 years old, and, was 10 years sober, off of all booze, benzo's, and nicotine. Yet, I am chronically depressed, and, have not worked a 40 hour a week
job, since the year of my Divorce, 5 years ago. No motivation anymore. Burned out on psychoanalysis, from DBT to Relapse Prevention therapy. I gave up
on relationships, and dating, the year my wife left me in 2007. Again, in spite of the gains, acquired the first 5 years of my A.D.D medication use, and
what society deems in our culture, as SUCCESS, I am ultimately depressed 24/7 "with or without uppers, and, I tried everything in the PDR except Desoxyn
for my ADD. (in terms of appropriate stimulants, Wellbutrin, and, many other combo meds already mentioned for atypical depression.
I love that feeling n all, ii just don't like stuff that makes it hard(er) to be social \:. Cuz even now on the dex I'm on ppl ask me if I'm wired jus cuz how I talk. Stuff n that bothers me-dnt get me rong tho I love the boost dex gives me
