Alendronate
Bones, joints, and goutAlso known as Fosamax
Alendronate treats osteoporosis by slowing the cells that break down bone, so your bones can rebuild density and resist fractures. It works quietly over months and years. The one thing you must get right is how you take it: the pill can badly burn your food pipe if it doesn't go straight down and stay down, so the morning ritual isn't a suggestion — it's the whole deal.
How to take it
When
First thing in the morning, empty stomach, with a full glass of plain water — nothing else.
Food
No food, drink, or other pills for at least 30 minutes after. Plain water only.
Avoid
Lying down for at least 30 minutes after taking it — stay sitting or standing upright.
Good to know
Take calcium and vitamin D at a DIFFERENT time of day — they block this medicine.
Missed a dose?
For the once-weekly version, take it the next morning after you remember, then go back to your regular day. Never take two tablets on the same day, and never double up.
