How should I take dextroamphetamine?
Take this medication exactly as it was prescribed for you. Do not take the medication in
larger amounts, or take it for longer than recommended by your doctor. Follow the directions on
your prescription label.
Your doctor may occasionally change your dose to make sure you get the best results from
this medication.
Take this medication with a full
glass of water.
Do not take dextroamphetamine in the evening because it may cause sleep problems
(insomnia).
Do not crush, chew, break, or open an extended-release capsule. Swallow the pill
whole. It is specially made to release medicine slowly in the body. Breaking or opening the pill
would cause too much of the drug to be released at one time.
To be sure this medication is helping your condition, your doctor will need to see you on a
regular basis. Do not miss any scheduled visits to your doctor.
This medication can cause you to have unusual results with certain medical tests. Tell any
doctor who treats you that you are using dextroamphetamine.
Store dextroamphetamine at room temperature away from moisture, heat, and light.
Dextroamphetamine is a drug of abuse and may be habit-forming. Keep track of how
many pills have been used from each new bottle of this medicine. You should be aware if any
person in the household is using this medicine improperly or without a prescription.
Using this medication improperly can cause death or serious side effects on the heart.
What happens if I miss a dose?
Take the missed dose as soon as you remember. If it is almost time for your next dose, or
if it is already evening, skip the missed dose and take the medicine the next morning. Taking this
medicine late in the day can cause sleep problems. Do not take extra medicine
to make up the missed dose.
What happens if I overdose?
Seek emergency medical attention if you think you have used too much of this
medicine. An overdose of dextroamphetamine can be fatal.
Overdose symptoms may include restlessness, tremor, muscle twitches, rapid breathing,
confusion, hallucinations, panic, aggressiveness, muscle pain or tenderness, muscle weakness,
fever or flu symptoms, and dark colored urine. These symptoms may be followed by depression
and tiredness. Other overdose symptoms include nausea, vomiting, diarrhea, stomach pain,
uneven heartbeats, feeling light-headed, fainting, seizure (convulsions), or coma.
What should I avoid while taking dextroamphetamine?
Dextroamphetamine can cause side effects that may impair your thinking or
reactions. Be careful if you drive or do anything that requires you to be awake and alert.
Do not take dextroamphetamine late in the day. A dose taken too late in the day can cause
sleep problems (insomnia).
Avoid drinking fruit juices or taking vitamin C at the same time you take
dextroamphetamine. These can make your body absorb less of the medicine.
