What happens if I miss a dose (Adderall)?

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 (Adderall)?

Seek emergency medical attention if you think you have used too much of this medicine. An overdose of amphetamine and dextroamphetamine can be fatal.

Overdose symptoms may include restlessness, tremor, muscle twitches, rapid breathing, confusion, hallucinations, panic, aggressiveness, unexplained 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.

Amphetamine and 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.
