How brand name and generics drugs differ?

Different inactive ingredients: In a brand name and generic drugs relationship, the difference is the inactive ingredient contained in the drugs. Since what the FDA is particular about is the active ingredients, generic and brand name drugs’ inactive ingredients are different. It is why it is important to look through the ingredient list on the drug label to see if there is any ingredient not good for you.

Cheaper than the brand name drugs: the cash price and insurance co-pay is typically lower. The cost can be lesser between 20 and 80 percent. It is meant to be because generic drugs companies do not bear the same investment costs as the brand name company.

Different manufacturers: Different manufacturers produce generic drugs, and you will receive your type of drug depending on which manufacturer your drug store uses.
