Aim:  Dexamphetamine has 3 main uses in adult psychiatry.

  1. To supplement the benefits obtained from antidepressants;
  2. To overcome chronic exhaustion or excessive need for sleep (which can sometimes occur as a side effect of the needed dose of antidepressants; and
  3. To treat Attention Deficit Hyperactivity disorder (the medication si widely used in children for this reason).

 

Mechanism of Action:  This medication increases the availability and the release of chemicals in the brain known as neurotransmitters, whose balance controls depression.

 

Dosage:  It is important to use the lowest dose possible so that the production of brain neurotransmitters can keep up with the extra supply demanded by the use of Dexamphetamine.  High doses of Dexamphetamine run the risk of transient benefit followed by a worsening of symptoms, due to exhaustion of the supply of neurotransmitters.  For most people, 3 to 6 tablets per day is the best dose.

 

Timing of Medication:  As this medication is strongly energising it must be taken in the morning and perhaps also at lunchtime in a lower dose.  The effects usually last 4 to 6 hours approximately.  Before or after food does not matter.  Taking the medication late in the afternoon or at night will probably interfere with your sleep.

 

Addiction:  High dose and prolonged use run the risk of addiction.  Do not try to increase the dose without discussing this with your doctor.  From time to time, we will reduce and try to stop the medication for a few days, provided your symptoms are tolerable with this tactic. Note that this medication is considerably different to methamphetamine (ice).

 

Side Effects:  You may experience some, or none, of the following:

  • Sleep disturbance.
  • Agitation, anxiety, irritability, mood swings.
  • Increased heart rate and blood pressure, palpitations, dizziness.
  • Jaw clenching and grinding teeth.
  • Loss of appetite, hands shaking, sexual problems.
  • Rare: – Addiction, paranoid feelings, psychotic symptoms, convulsions.

 

Legal Controls:  A Department of Health permit allowing the medication to be prescribed for you is usually compulsory in most countries.  Your doctor and the Department of Health will monitor the number of tablets you are prescribed.

    Colleen, I havn’t noticed anxiety going away. I do have loss of appetite which is good because dex also fights impulses like binge eating. I’ve been on forms of dexamphetamine or close to 11 years since I was 22. I’ve gone periods without, and my overall life outlook was worse(not terrible) and when I Re started medication (10mg capsules sustained release 1-6 daily) I saw overall quality of life go up. So for depression I can see how it would work even though I’m not depressed before or after, I was diagnose with ADHD as an adult and have been on 10mg capsules for 11 years, I did try Vyvanse, which I thought worked really well and really curbed my impulses for binge eating. I hope this helps! 🙂

      I get the exact same affect, my anxiety is worse, I feel depressed and I’m always on edge, it fills my personality so much but it helps me at work to focus, I stopped taking them for 6 weeks and loved being fun and bubbly and happy again but I hate when I take them my anxiety shoots through the roof, I don’t know if this is normal or what is going on but it’s ruin my relationship…

        Dexy is for some and not for others…I was on Zoloft for many years for depression, but still struggled with the black dog while on Zoloft…I tried Dexies 12 years ago after my son was diagnosed with ADHD (also think I am ADHD but wasn’t known of in my time as a child and was advised I woudln’t be able to get prescribed dexies)…the dexies worked awesome for me…so maybe depends IF you are depressed or ADHD…think I need to try and get on them permanently now but not too sure how…
