Fosamax : Uses, Side Effects, Interactions & More

Why is this medication prescribed?

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

How should this medicine be used?

Fosamax (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 generally taken on an empty stomach once a day in the morning, and the 35 mg and 70 mg tablets are generally 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. Effervescent tablets are usually taken on an empty stomach once a week in the morning. Follow the directions on your prescription label carefully and ask your doctor or pharmacist to explain any parts you do not understand. Take Fosamax exactly as directed. Do not take more or less or take it more often than prescribed by your doctor.

Fosamax 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 should take Fosamax right after you get out of bed in the morning, before you eat or drink anything. Never take Fosamax before bedtime or before waking up and getting out of bed for the day.
  • After taking Fosamax, 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 taking Fosamax. Sit upright or stand upright until at least 30 minutes have passed and you have eaten your first meal of the day.
  • If you are taking Fosamax tablets, swallow the tablet with a full glass (6 to 8 ounces [180 to 240 ml] ) of plain water. Never take Fosamax tablets with tea, coffee, juice, milk, mineral water, sparkling water, or any other liquid other than plain water. Swallow the tablets whole; do not split, chew, or crush them. Do not suck the tablets.
  • If you are taking Fosamax oral solution, drink at least 2 ounces (1/4 cup [60 milliliters] ) of water after taking Fosamax oral solution. Never take Fosamax solution with tea, coffee, juice, milk, mineral water, sparkling water, or any other liquid other than plain water.
  • If you are taking Fosamax effervescent tablets, dissolve one effervescent tablet in a full glass (4 ounces [120 milliliters] ) of still drinking water before drinking. Never dissolve Fosamax effervescent tablets in tea, coffee, juice, milk, mineral water, sparkling water, or any other liquid other than plain water. Wait at least 5 minutes after the fizzing stops, stir the solution for 10 seconds and drink it. Do not swallow, suck, or chew the effervescent tablets.

Fosamax controls osteoporosis and Paget’s disease of bone, but it does not cure these conditions. It may take 3 months or more before your bone density begins to increase. Fosamax helps treat and prevent osteoporosis only if it is taken regularly. Keep taking Fosamax even if you feel fine. Do not stop taking Fosamax without talking to your doctor, but do talk to your doctor from time to time about whether you still need to take Fosamax.
