Cialis is better

Fosamax is the brand name for alendronate sodium. Fosamax is prescribed for the treatment of osteoporosis (thinning of bone) in women after menopause. It is most commonly prescribed to be taken once weekly and is available in both pill and liquid forms.
Fosamax works by:

Reducing the activity of the cells that cause bone loss

Decreasing the faster rate of bone loss that occurs after menopause

Increasing the amount of bone in most patients   These effects are seen as soon as three months after Fosamax therapy has begun. These effects continue as long as you keep taking Fosamax. The density of bone increases and the bone is less likely to fracture. Thus, Fosamax reverses the progression of osteoporosis. Patients should not take Fosamax if they have any of the following conditions:

Low levels of calcium in their blood

Severe kidney disease

Allergy to Fosamax   In addition, patients should not take Fosamax if they are pregnant or nursing.  (Fosamax is for use by women after menopause. If you are pregnant or nursing, you should not take Fosamax. Talk to your doctor.) Before your doctor prescribes Fosamax, be sure to talk to your doctor about:

Problems with swallowing

Digestive problems

Other medical problems you have or have had in the past

Like all prescription drugs, Fosamax may cause side effects. In the past, patients who have taken Fosamax have usually had mild side effects. The side effects generally have not caused patients to stop taking Fosamax.  Some patients treated with Fosamax in clinical studies experienced abdominal (stomach) pain, which was the most commonly reported side effect. Less frequently reported side effects were other digestive problems such as:

Nausea

Heartburn

Irritation or pain of the esophagus (the tube that connects your mouth with your stomach)

Vomiting

Difficulty swallowing

A full or bloated feeling in the stomach

Constipation

Diarrhea

Gas  Muscle/bone pain, headaches, or an altered sense of taste were also experienced by some patients. in rare cases, rashes may occur. Anytime you have a medical problem you think may be related to Fosamax, talk to your doctor.
