Need 30 mg? Walmart Charges You For Three 10 mg $4.00 Prescriptions

WalMart advertises that generic prescriptions are just $4.00 for up to a 30 day supply. What they don’t tell you is that it must be what they consider a “commonly prescribed dosage,” so if your doctor decides you need a different dosage they count it as separate prescriptions. For example, if a pill comes in 10mg, 20mg or 40mg strengths and your doctor wants you to take 30mgs. WalMart counts that as 3 – 10mg prescriptions and charges you $12.00 for a 30 day supply.

The information about the dosage is not on the store signs, I found it on their website. Recently I had such a prescription filled; when I questioned the pharmacist about the price difference he became upset and was very rude to me.

We understand that the Walmart $4.00 generic program is for pills in commonly prescribed doses, but we’re a little confused as to why they charged you for three 10mg prescriptions when they could charge you for one 20 mg prescription and one 10 mg prescription. Maybe they thought that was too complicated?

Any pharmacists out there want to explain how this works?
