How should I take alendronate?
Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.
Alendronate is taken either once daily or once per week. Follow your doctor's dosing instructions very carefully.
Take alendronate first thing in the morning, at least 30 minutes before you eat or drink anything or take any other medicine. If you take alendronate only once per week, take it on the same day each week and always first thing in the morning.
Take with a full glass (6 to 8 ounces) of plain water. Do not use coffee, tea, soda, juice, or mineral water. Do not eat or drink anything other than plain water.
Measure liquid medicine carefully. Use the dosing syringe provided, or use a medicine dose-measuring device (not a kitchen spoon).
Do not crush, chew, or suck on an alendronate regular tablet. Swallow it whole.
Dissolve the effervescent tablet in at least 4 ounces of water (at room temperature, not hot or cold). Let the tablet dissolve for 5 minutes. Stir this mixture for 10 seconds and drink all of it right away. Add a little more water to the glass, swirl gently and drink right away.
For at least 30 minutes after taking alendronate:
Do not lie down or recline.
Pay special attention to your dental hygiene while taking alendronate. Brush and floss your teeth regularly. If you need to have any dental work (especially surgery), tell the dentist ahead of time that you are using alendronate.
Alendronate is only part of a complete program of treatment that may also include diet changes, exercise, bone mineral density testing, and taking calcium and vitamin supplements. Follow your doctor's instructions very closely.
Store at room temperature away from moisture and heat. Keep unused effervescent tablets in the foil blister pack.
Your doctor will determine how long to treat you with this medicine. Alendronate is often given for only 3 to 5 years.
What happens if I miss a dose?
Once-daily dosing: If you forget to take alendronate first thing in the morning, do not take it later in the day. Wait until the following morning and skip the missed dose. Do not take two (2) doses in one day.
Once-per-week dosing: If you forget to take alendronate on your scheduled day, take it first thing in the morning on the day after you remember the missed dose. Then return to your regular weekly schedule on your chosen dose day. Do not take 2 doses in one day.
What happens if I overdose?
Drink a full glass of milk and seek emergency medical attention or call the Poison Help line at 1-800-222-1222. Do not make yourself vomit and do not lie down.
What should I avoid while taking alendronate?
Avoid taking any other medicines for at least 30 minutes after taking alendronate. This includes vitamins, calcium, and antacids. Some medicines can make it harder for your body to absorb alendronate.
Avoid smoking, or try to quit. Smoking can reduce your bone mineral density, making fractures more likely.
Avoid drinking large amounts of alcohol. Heavy drinking can also cause bone loss.
