Proper Use of alendronate

Read and follow the instructions on the patient package insert carefully. Ask your doctor or pharmacist if you have any questions .

Take the alendronate tablet with a full glass (6 to 8 ounces) of plain water on an empty stomach. It should be taken as soon as you get out of bed in the morning and at least 30 minutes before any food, beverage, or other medicines. Food and beverages, such as mineral water, coffee, tea, or juice, will decrease the amount of alendronate absorbed by the body. Waiting longer than 30 minutes will allow more of the drug to be absorbed. Medicines such as antacids, calcium, or vitamin supplements will also decrease the absorption of alendronate .

If you are using alendronate oral solution, drink at least 2 ounces (a quarter of a cup) of water immediately after taking the medicine. This will allow the medicine to reach your intestines and be absorbed by the body more quickly .

Do not lie down for at least 30 minutes after taking alendronate and before having your first food for the day. This will help alendronate reach your stomach faster. It will also help prevent irritation to your esophagus .

Do not take alendronate at bedtime or before getting up for the day .

Swallow the tablet whole. Do not crush, break, chew, or suck it .
