Frequently asked questions

Which is cheaper, Amrix or Soma?

Amrix costs pharmacies less to acquire — about $0.63 vs $2.00 for a 30-count supply, per the CMS NADAC survey. That gap is in the pharmacy's cost of goods, not necessarily in what you pay: your price is set afterwards by your insurer and the pharmacy.

What is the difference between Amrix and Soma?

Amrix contains Cyclobenzaprine Hydrochloride, while Soma contains Carisoprodol — they have different active ingredients.
