Dexedrine is made up of 1 amphetamine salt which is dextroamphetamine. Adderall is made up of 4 amphetamine salts, 1 of which is dextroamphetamine which makes up 25% of the Adderall pill. Ritalin usually requires a dosage similar to Adderall and twice that of Dexedrine to be effective. Difference in effect: Adderall is prescribed in approximately twice the dosage of Dexedrine. A 10mg pill of Adderall contains 2.5mg of Dexedrine but has similar effect as 5mg of Dexedrine. Due to the 4 different salts and increased dosage needed, Adderall is more likely to give side effects than Dexedrine.
