How should I take Alendronate
Alendronate comes as a tablet, an effervescent tablet, and a solution (liquid) to take by mouth. The solution is usually taken on an empty stomach once a week in the morning. The 5-mg and 10-mg tablets are usually taken on an empty stomach once a day in the morning, and the 35-mg and 70-mg tablets are usually taken on an empty stomach once a week in the morning. The 40-mg tablets are usually taken once a day in the morning for six months to treat Paget's disease of bone. The effervescent tablets are usually taken on an empty stomach once weekly in the morning. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take alendronate exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Alendronate may not work properly and may damage the esophagus (tube between the mouth and stomach) or cause sores in the mouth if it is not taken according to the following instructions. Tell your doctor if you do not understand, you do not think you will remember, or you are unable to follow these instructions:
- 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.
- 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.
- If you are taking the alendronate tablets, swallow the tablet with a full glass (6 to 8 ounces [180 to 240 mL]) of plain water. Never take alendronate tablets 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.
- If you are taking the alendronate oral solution, drink at least 2 ounces (60 milliliters [1/4 cup]) of water after taking alendronate oral solution. Never take alendronate solution with tea, coffee, juice, milk, mineral water, sparkling water, or any liquid other than plain water.
- If you are taking the alendronate effervescent tablets, dissolve one effervescent tablet in a full glass (4 ounces [120 milliliters]) of plain, non-carbonated drinking water before drinking. Never dissolve alendronate effervescent tablets with tea, coffee, juice, milk, mineral water, sparkling water, or any liquid other than plain water. Wait at least 5 minutes after the effervescence stops, stir the solution for 10 seconds and drink it. Do not swallow, suck, or chew on the effervescent tablets.
Alendronate controls osteoporosis and Paget's disease of bone but does not cure these conditions. It may take 3 months or longer before your bone density begins to increase. Alendronate helps to treat and prevent osteoporosis only as long as it is taken regularly. Continue to take alendronate even if you feel well. Do not stop taking alendronate without talking to your doctor, but talk to your doctor from time to time about whether you still need to take alendronate.

What should I know about storage and disposal of this medication?
Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom). Do not freeze alendronate solution.
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org
Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.
What special dietary instructions should I follow?
You should eat and drink plenty of foods and drinks that are rich in calcium and vitamin D while you are taking alendronate. 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.
What should I avoid while using 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.
