Key Points

  • The cash price for Onfi is roughly $2,300 for 100 tablets of the 10 mg strength and $4,600 for 100 tablets of the 20 mg strength using a widely accepted coupon.
  • The oral 2.5 mg/mL suspension costs about $1,200 for 120 mL (4 ounces).
  • Onfi (clobazam) is available as both a brand name medicine and as a generic option. A generic drug might save you money if you are paying for your prescriptions out-of-pocket.

The Onfi (clobazam) prices are based on using the discount card which is accepted at most U.S. pharmacies.

Drug prices can vary widely and change often. When there is a range of prices, consumers usually pay the lower price, but there is no guarantee this will always be the case.

Check with several of your local pharmacies to compare prices if you are paying cash for your medications. Ask your pharmacist and doctor how to best save money on your prescriptions.
