Why Isn There Any Generic Lodosyn?
It is not entirely clear why there are no generic versions of Lodosyn. The patents for this product are long expired, and there is no reason why a generic manufacturer would not be allowed to make generic Lodosyn. Most likely, no generic manufacturers have chosen to do so because Lodosyn is a rarely used medication (and it would probably not be profitable for a company to make generic Lodosyn). Most people take carbidopa in combination carbidopa-levodopa products (such as Sinemet®, Sinemet® CR, Parcopa®, and Stalevo®) and do not need to take any additional carbidopa.
