Common questions

- Who makes Triamterene?
- 6 companies have marketed Triamterene in the last 30 days, according to the FDA NDC Directory. Every manufacturer and package is listed on this page.
- What does Triamterene cost?
- The typical pharmacy pays about $6.62 per unit, based on the most recent CMS NADAC survey of actual acquisition costs. That is what the pharmacy pays for the drug itself — not the cash price, and not what an insurer is billed.
