Drug class
Bisphosphonates: medications in this class
Medications that prevent bone loss and treat osteoporosis.
Overview
Bisphosphonates bind to bone and slow the cells that break it down, so bone density stabilises or rises and the risk of hip and spine fractures falls. They are first-line for osteoporosis in postmenopausal women and in men, and for bone loss caused by long-term steroids.
Alendronate is taken once a week, risedronate weekly or monthly, ibandronate monthly, and zoledronic acid as a yearly intravenous infusion. The oral forms must be taken first thing with a full glass of water, standing or sitting upright for a set time before food, to avoid oesophageal irritation; that routine is the main reason people stop. Rare risks with long use are atypical thigh fractures and jaw osteonecrosis, so prescribers reassess after several years.
Calcium and vitamin D intake is checked alongside, and dental work is best completed before starting.
How the drugs in this class differ when you pay cash
Alendronate is a commodity generic and sits on most flat-price lists; weekly dosing means only a handful of tablets per fill, so the dispensing fee is most of the price and a ninety-day supply makes sense. Risedronate and ibandronate are generic but cost pharmacies more and vary by pharmacy; the delayed-release risedronate (Atelvia) and the brands Fosamax, Actonel and Boniva add nothing for a cash-paying patient. The alendronate-with-vitamin-D combination is priced above plain alendronate.
Zoledronic acid is administered in a clinic or infusion centre, so its cost is a procedure charge rather than a pharmacy quote.
Alendronate also comes as an oral solution and an effervescent tablet for people who cannot swallow the standard tablet; both cost more and are stocked less widely. If a brand is named on the prescription, ask the prescriber to allow generic substitution.
When paying cash beats a copay, and when it does not
For alendronate a cash quote from a flat-price, independent or mail-order pharmacy is usually at or below a copay. For risedronate and ibandronate, compare. Newer non-bisphosphonate injectables (denosumab, teriparatide) are brand-priced and are where insurance matters most.

Questions worth asking
- Exactly how should I take the tablet, and how long must I stay upright?

- Should I take calcium and vitamin D with it?
- Should I finish dental work before starting?
- Is a ninety-day prescription appropriate?
