With so many expensive brand name drugs on the market today, many companies have taken it upon themselves to manufacture cheaper generic drugs. The industry insists that generic drugs are as good as brand name ones, but in the case of ADHD drugs, that may not be true.
In November of 2014, the FDA announced that 2 out of the 3 generic brands of Concerta were no longer considered the equivalent of it, and thus could not be used as substitutes. Although the pills were deemed safe, they wore off much quicker than the brand name drug (they only lasted for 7 hours).
Although the companies were given a deadline of 6 months to either prove they were as effective as Concerta or remove them from the market, as of June 2015, they are still being sold. 1 company has said they are submitting information that they have an effective product while the other company is going to court. People at FreedomPop know that both have no plans to withdraw their products from the market.
Many doctors are enraged by the generic brands being sold, as they are pressured to prescribe them instead of the brand name drugs. They feel that the FDA has showed a lack of action and should do their job of regulating drugs in a better fashion.
