What can it be used for?

  • 18 & Over
    If you are 18 or over, there is less research about its use and effectiveness for ADHD in adults. Even so, specialists might prescribe it ‘off label’ if it is the best medicine for you. Dexamfetamine can be used in adults who have narcolepsy, where they fall asleep too easily and without warning.
  • Under 18
    If you are 17 or under, the doctor can prescribe dexamfetamine for you as a licensed medicine for treatment of attention deficit hyperactivity disorder (ADHD)

Ways to take and what's in it?

  • Tablets

    5mg strength

  • Liquids

    1mg/ml One 5ml spoonful of the oral solution is like one tablet.

Dexamfetamine can be used to help with attention deficit hyperactivity disorder (ADHD).

If you have taken more dexamfetamine than it said on the label, you must see a doctor quickly – even if you do not feel any different.

Dexamfetamine can cause serious side-effects: allergic reactions (high body temperature, swelling of your face or throat, itching skin lumps), twitching and other symptoms, found in the warnings section. Go to a hospital if you get any of these symptoms, with your medicine

Do not take dexamfetamine if you have taken a monoamine oxidase inhibitor antidepressant (MAOI) like moclobemide, phenelzine, isocarboxazid or tranylcypromine in the last 14 days.

Stopping dexamfetamine suddenly can cause serious side-effects – go to your doctor if you want to stop, or if you are having these effects.

You might feel sleepy or have eyesight problems in the first few days after taking dexamfetamine – do not drive a car, ride a bike or operate machines until you see how this affects you.

If you take dexamfetamine while you are pregnant, it may affect the developing baby. Use good contraception while you are taking dexamfetamine. Dexamfetamine is passed to the baby in breastmilk. Talk to your doctor or midwife about this and get their help.
