Always speak to your physician about generic alternatives. One of the easiest ways to save money on your prescription immediately is by filling a generic alternative instead of the brand name.
The FDA requires generic drugs to have the exact same active ingredients make-up as their branded counterpart. Sometimes the inactive ingredients, like color dyes, may be different than the brand name. Speak to your pharmacist or physician if you have any concerns about switching to the generic version of your treatment.
