Alendronate-Fosamax
Why
is this medication prescribed?
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).
What
is the most important information I should know about alendronate?
• Do not take an alendronate tablet if you cannot sit upright
or stand for at least 30 minutes. Alendronate can cause serious problems
in the stomach or esophagus (the tube that connects your mouth and
stomach). You will need to stay upright for at least 30 minutes after
taking this medication.
• Take the alendronate tablet first thing in the morning, at
least 30 minutes before you eat or drink anything or take any other
medicine.
• Take each dose with a full glass (6 to 8 ounces) of water.
Use only plain water (not mineral water) when taking an alendronate
tablet.
• For at least the first 30 minutes after taking an alendronate
tablet, do not lie down or recline; do not eat or drink anything other
than plain water; and do not take any other medicines including vitamins,
calcium, or antacids.
• Some people using medicines similar to alendronate have developed
bone loss in the jaw, also called osteonecrosis of the jaw. Symptoms
of this condition may include jaw pain, swelling, numbness, loose
teeth, gum infection, or slow healing after injury or surgery involving
the gums. You may be more likely to develop osteonecrosis of the jaw
if you have cancer or have been treated with chemotherapy, radiation,
or steroids. Other conditions associated with osteonecrosis of the
jaw include blood clotting disorders, anemia (low red blood cells),
and a pre-existing dental problem.
• Alendronate is only part of a complete program of treatment
that may also include diet changes, exercise, and taking calcium and
vitamin supplements. Follow your diet, medication, and exercise routines
very closely.
How should you use medication?
Alendronate is effective only when each tablet or bottle of oral solution
is taken with a full glass of plain water first thing in the morning,
at least 30 minutes before the first food, beverage, or other medication.
If you can wait longer before eating or drinking, the medication will
be absorbed better. Do not lie down after taking Alendronate until
at least 30 minutes have passed and you've had something to eat.
Avoid chewing or sucking on the tablet; it can cause mouth sores.
You should take calcium and vitamin D supplements if you don't get enough in your diet. Avoid smoking and alcohol. Weight-bearing exercise can also strengthen bones.
