The government has created special regulations that determine how Adderall is prescribed and dispensed. These regulations also require that you get a new prescription from your doctor for each refill. Adderall oral tablet and Adderall XR extended-release oral capsule are both available in generic forms. The generic name for the drug in both the tablet and the capsule is amphetamine/dextroamphetamine salts. These side effects may go away within a few days or a couple of weeks. If they’re more severe or don’t go away, talk to your doctor or pharmacist.
