From the pharmacy counter → to YOU
Alendronate is one of the most misused osteoporosis medications I see.
It’s not just what you take — it’s how you take it.
Take it wrong
• More side effects
• Little to no benefit
Take it right
• Stronger bones
• Real fracture protection
Most people were NEVER told this properly.
Were you given these instructions when you picked it up?
Save this — this one matters.
