Doctors often prescribe stimulant medications to help treat adult ADD, states WebMD. Popular amphetamine-based stimulants include Adderall, Dexedrine, Dextrostat, ProCentra and Vyvanse. Methylphenidate-based medications include Concerta, Daytrana, Focalin, Metadate and Ritalin.
These medications come in both short- and long-lasting varieties. The short-lasting drugs last for about four hours, while the long-lasting drugs last eight to 12 hours, according to WebMD. Most people take the short-lasting drugs twice a day, while the long-lasting drugs only need to be taken once a day. It is important for people with heart disease, glaucoma, or drug and alcohol problems to warn their doctors before taking these drugs.
