How much is cephalexin without Insurance in the US?

Our website gives two competitive savings options to US customers who wish to purchase cephalexin, as either a brand or generic, if available. The first is access to medications through our mail-order online pharmacy. The second is by using the Now Patient Rx Advantage Card, which can be used in over 65,000 pharmacies nationwide, across America. If you are insured, then in most cases, the cash price will be significantly cheaper than the copay.

We also anticipate being able to handle more complex scenarios such as using primary insurance combined with a manufacturer copay assistance program.
