Fosamax is a drug prescribed to treat and prevent bone diseases like osteoporosis.
How It Works
The active ingredient in Fosamax is alendronate acid. This acid belongs to a group of drugs called bisphosphonates.
These drugs can slow down the rate at which the body loses old bone tissue. When the body retains old bone tissue while continuing to make new bone tissue, it leads to an increase in bone density. This can reduce the risk of bone fractures.
Fosamax is mainly prescribed to treat osteoporosis, a condition that mainly affects women and is also known as brittle bone disease. Osteoporosis makes bones fragile and prone to breaking and fracturing. The risk for osteoporosis is high among people older than 30, when the body begins to lose bone density. Women who undergo menopause lose bone density at a faster pace. Taking Fosamax can prevent the onset or exacerbation of osteoporosis.
Fosamax is also prescribed to men and women with Paget’s disease, a condition where the body’s ability to replace old bone tissue with new bone tissue is disrupted.
Fosamax is available in 10 mg tablets. Individual dosage may vary depending on a number of factors. Your doctor will prescribe you the correct dosage to best treat your condition.
Fosamax is usually prescribed as 10 mg tablet taken on a daily basis. In some cases, physicians may prescribe 70 mg tablets to be taken once a week.
Follow the dosage and schedule exactly as prescribed by your doctor. Do not miss doses or take double doses. Taking double doses increases your risk for severe side effects caused by the drug.
Take Fosamax the same time each day. To reduce possible damage to the esophagus, take the tablets with a glass of water (about 240 mL). Drink with plain water, not mineral water.
Swallow the tablet whole without chewing, crushing or breaking.
Once you have taken the pill, stay fully upright in a sitting, standing or walking position for 30 minutes straight. Do not lie down, recline, eat or drink anything (except plain water) for at least 30 minutes after taking Fosamax. Do not take any other medicines, vitamins, calcium supplements or antacids for 30 minutes after taking Fosamax.
You must take Fosamax on an empty stomach. Take the medicine and wait at least 30 minutes before eating a meal.
It’s recommended to wait an hour or two before eating anything after taking this drug.
Don’t take Fosamax at bedtime or before waking up in the morning. The drug may not be absorbed by the body and side effects may worsen.
The following side effects may occur when taking Fosamax:
Do not take Fosamax if allergic to any of the ingredients in the drug.
You should be able to maintain an upright position for 30 minutes after taking the drug. If you are unable to do this, Fosamax may not be for you.
Ask your doctor regarding safety of taking Fosamax. Certain medical conditions, other drugs, supplements and vitamins may make Fosamax unsafe to consume.
Certain food items and supplements— like vitamins, coffee, tea, mineral water, calcium-enriched juices—can decrease absorption of Fosamax by the body. You should not consume these food items ideally until an hour after taking Fosamax.
