What is the difference between ALENDRONATE SODIUM and RISEDRONATE SODIUM?

ALENDRONATE SODIUM and RISEDRONATE SODIUM are both Bisphosphonates, so they work through the same broad mechanism. They differ in dosing, half-life, side-effect frequency, and how individual patients tolerate them. See the head-to-head sections below for the specifics.

Is Binosto the same as RISEDRONATE SODIUM?

No. Binosto (ALENDRONATE SODIUM) and RISEDRONATE SODIUM (RISEDRONATE SODIUM) are distinct medications. They are sometimes confused because of similar branding or because they treat overlapping conditions, but they have different active ingredients and different safety profiles.

Which has fewer side effects, ALENDRONATE SODIUM or RISEDRONATE SODIUM?

Side-effect frequency varies by individual. The side-effect comparison section on this page shows FAERS-reported events for each drug side by side. FAERS is voluntary reporting, so it reflects what patients and clinicians chose to report, not absolute population risk.

Can I switch from ALENDRONATE SODIUM to RISEDRONATE SODIUM?

Switching medications should always be done under prescriber supervision. The "patient stories" section on this page includes accounts from people who have made the switch and what their transition felt like, but those are individual experiences, not protocols.

ALENDRONATE SODIUM

5 WARNINGS AND PRECAUTIONS Upper Gastrointestinal Adverse Reactions can occur
Risk/benefit of continuing bisphosphonate therapy should be re-evaluated in these patients and interruption of bisphosphonate therapy should be considered
The risk of severe esophageal adverse experiences appears to be greater in patients who lie down after taking oral bisphosphonates including alendronate sodium, and/or who continue to take oral bisphosphonates including alendronate sodium after developing symptoms suggestive of esophageal irritation
There have been post-marketing reports of gastric and duodenal ulcers with oral bisphosphonate use, some severe and with complications, although no increased risk was observed in controlled clinical trials [see Adverse Reactions (6

RISEDRONATE SODIUM

5 WARNINGS AND PRECAUTIONS • Products Containing Same Active Ingredient : Patients receiving Actonel should not be treated with risedronate sodium delayed-release tablets (5
The risk of severe esophageal adverse experiences appears to be greater in patients who lie down after taking oral bisphosphonates and/or who fail to swallow it with the recommended 4 ounces of water, and/or who continue to take oral bisphosphonates after developing symptoms suggestive of esophageal irritation
There have been post-marketing reports of gastric and duodenal ulcers with oral bisphosphonate use, some severe and with complications, although no increased risk was observed in controlled clinical trials
Known risk factors for osteonecrosis of the jaw include invasive dental procedures (for example, tooth extraction, dental implants, boney surgery), diagnosis of cancer, concomitant therapies (for example, chemotherapy, corticosteroids, angiogenesis inhibitors), poor oral hygiene, and co-morbid disorders (for example, periodontal and/or other pre-existing dental disease, anemia, coagulopathy, infection, ill-fitting dentures)
