There are many factors that determine the final price you pay for a medication. These include: ingredient costs, dispensing fees, and any applicable promotions or discounts from the manufacturer, distributor, or retailer. Each of these variables can change on a daily basis. DestinationRx makes every effort to update the prices on our website as frequently as possible. However, sometimes we are unable to keep up with each pharmacy's changes. Refer to the pharmacy itself to be sure of the current price of your drug.
