The primary differences usually lie in the inactive ingredients (like fillers, binders, and dyes), which can affect the tablet's appearance or, in rare cases, lead to slight variations in absorption [6].

Patients can often find price differences by comparing costs at various pharmacies or through online prescription price comparison tools.
