Adderall combines four drugs from the amphetamine family.
Side Effects: Irregular heartbeat, increased blood pressure, restlessness or tremor, anxiety or nervousness, headache, dizziness, insomnia, dryness of the mouth or unpleasant taste in the mouth, diarrhea or constipation, impotence or changes in sex drive.
Overdose Symptoms: Possible symptoms of overdose include restlessness, tremor, rapid breathing, confusion, hallucinations, panic, aggressiveness, nausea, vomiting, diarrhea, irregular heartbeat, and seizures.
Abuse and Dependency: Like Ritalin, Adderall has potential for abuse and dependence, especially among people who do not have ADHD. Continued use can result in tolerance to the drug, necessitating an increase in dosage to reap the same effects. Once discontinued, withdrawal effects such as depression may occur.
