Hello: While most patients can tolerate low dosages of Adderall prescription medicine with minimal problems, there are some dangerous or hazardous side effects you should discuss with your doctor before starting a treatment plan. High doses of Adderall can specifically target the heart and respiratory system, causing temporary or long-term damage. In some cases, Adderall can cause sudden death or stroke in patients, in particular those who have a heart defect or heart problem. Adderall may also interfere with other medication for an underlying illness or medical condition. Adderall taken for long periods of time throughout childhood and adolescence may stunt growth or weight gain and lead to long term complications related to development. Adderall acts a central-nervous stimulant. Adderall should be used as a temporary medication to help control symptoms and help regulate brain activity. Long-term use of Adderall as a prescription medication treatment for attention-deficit hyperactivity disorder may make symptoms worse and make withdrawal symptoms unbearable. Signs of withdrawal include severe depression or dysphoria, irritability, rage, trouble sleeping and an intense craving for the medication. Symptoms of attention-deficit hyperactivity disorder may be more severe during the withdrawal phase. Close supervision from a school psychologist or school personal is recommended until symptoms are under control with cognitive or behavioral therapy. I hope this is useful!
