Alendronate

What is Alendronate?

Alendronate is used to treat and prevent osteoporosis (a condition in which the bones become thin and weak and break easily) in women who have undergone menopause (change of life; end of menstrual periods). Alendronate is also used to treat osteoporosis in men and women, who are taking corticosteroids (a type of medication that may cause osteoporosis in some patients). Alendronate is also used to treat Paget's disease of bone (a condition in which the bones are soft and weak and may be deformed, painful, or easily broken). Alendronate is in a class of medications called bisphosphonates. It works by preventing bone breakdown and increasing bone density (thickness).

How

Ask your pharmacist or doctor for a copy of the manufacturer's information for the patient.

You must take alendronate just after you get out of bed in the morning, before you eat or drink anything. Never take alendronate at bedtime or before you wake up and get out of bed for the day.

Swallow alendronate tablets with a full glass (6 to 8 ounces, about 1 cup) of plain water. Drink at least a quarter of a cup (2 ounces) of plain water after you drink alendronate liquid. Never take alendronate with tea, coffee, juice, milk, mineral water, sparkling water, or any liquid other than plain water.

Swallow the tablets whole; do not split, chew or crush them. Do not suck on the tablets.

After you take alendronate, do not eat, drink, or take any other medications (including vitamins or antacids) for at least 30 minutes. Do not lie down for at least 30 minutes after you take alendronate. Sit upright or stand upright until at least 30 minutes have passed and you have eaten your first food of the day.

What If I Forget

If you miss a dose of once-daily alendronate, do not take it later in the day. Skip the missed dose and take one dose the next morning as usual. If you miss a dose of once-weekly alendronate, take one dose the morning after you remember. Then return to taking one dose once each week on your regularly scheduled day. Never take a double dose to make up for a missed one, and never take more than one dose in 1 day.

Your doctor will tell you which foods and drinks are good sources of these nutrients and how many servings you need each day. If you find it difficult to eat enough of these foods, tell your doctor. In that case, your doctor can prescribe or recommend a supplement.
