Actonel 35 12-Week is a brand-name bisphosphonate medication containing Risedronate Sodium 35 mg in a convenient 12-tablet pack (a 3-month supply taken once weekly). It is FDA-approved for the treatment and prevention of postmenopausal osteoporosis, increasing bone mass in men with osteoporosis, and treating and preventing glucocorticoid-induced osteoporosis. Risedronate is also approved for the treatment of Paget's disease of bone. Originally manufactured by Allergan (now AbbVie), generic versions are widely available.
Risedronate is a pyridinyl bisphosphonate that works by binding to hydroxyapatite crystals on the surface of bone. It specifically inhibits osteoclasts — the cells responsible for breaking down bone tissue. Risedronate blocks the enzyme farnesyl pyrophosphate synthase in the mevalonate pathway within osteoclasts, causing these bone-resorbing cells to undergo apoptosis (programmed cell death). This reduces the rate of bone breakdown, allowing bone-building cells (osteoblasts) to maintain and increase bone density over time.
The 12-week pack contains 12 tablets of Risedronate 35 mg, providing a convenient 3-month supply with once-weekly dosing.
Actonel 35 12-Week (Risedronate Sodium 35 mg, 12-tablet pack) is moderately easy to find. Generic Risedronate is manufactured by multiple companies and is not on the FDA drug shortage list. However, the specific 12-week packaging may not be stocked at every pharmacy — some locations carry only the standard 4-tablet monthly supply. If your pharmacy doesn't have the 12-week pack, ask them to order it or try a larger chain pharmacy. You can also use Medfinder to locate pharmacies with it in stock near you.
