Why

Fosamax is on the ISMP “Do Not Crush” list as a mucous membrane irritant. FDA labeling warns of severe esophageal reactions and potential oropharyngeal ulceration, instructing patients not to chew or suck the tablet and to swallow it with a full glass of plain water while staying upright.

What to ask the pharmacist instead

Ask the pharmacist about the FDA-approved alendronate oral solution or other osteoporosis treatments that do not require swallowing a tablet.
