Fosamax is used for the treatment of osteoporosis among women in their post menopausal stage. It is known in its generic name alendronate. It belongs to the group of biophosphonates, a compound responsible for the prevention of bone loss.

What Should Be Considered Before Taking Fosamax

Some patients suffering from post-menopausal osteoporosis are not suitable with Fosamax. To know whether a patient could use Fosamax as a treatment for post-menopausal osteoporosis, the doctor should have the detailed medical, drug and allergy history of the patient. This is also helpful for the doctors to determine the rightful dose and schedule for the patient in need of treatment.

Those patients with current condition or history of low blood calcium, kidney disease, esophagus or stomach ulcer and kidney disease will not be prescribed Fosamax. Should the doctor become unable to find alternative treatment, Fosamax will be administered to the patient but with close monitoring. Patients with current medications which include herbal remedies, OTC and prescribed medications should be closely monitored as well, because Fosamax is known to have negative interactions with some medications. During Fosamax treatment, patients will, and should not be given these medications: ibuprofen, Naproxen, ketorolac and other pain relievers categorized under NSAID.

Fosamax is categorized by the Food and Drug Association of America as a category C pregnancy risk. This means that the medication causes damage to the unborn baby. It is yet unknown for Fosamax to pass through the mother’s milk, but this medication is mostly not prescribed among women who are doing breastfeeding.

Dosage and Administration

Fosamax is available in a variety of doses: 5 mg, 10 mg, 35 mg and 70 mg. All of these doses come in tablets and bottled solutions, which could be taken orally or intravenously.

The medication should be taken according to the dose and schedule prescribed by the attending physician. In the event that a patient misses one of the scheduled doses, it should be taken as soon as recalled. But if the next scheduled dose is near from the previous one, it is best to disregard the missed schedule.  It is not a good idea to double the dose in a single sitting just to make up for the missed dose. Doing so will subject the patient to an overdose.

Patients taking other medications should be approved by the doctor and should be taken half an hour after intake of Fosamax. This will include vitamin supplements as well.

What To Do In An Overdose

A patient overdosed with Fosamax might manifest any of these symptoms: tightness or swelling of the muscles in the facial area, nausea and vomiting, any tingling or numb sensation in any area of the body, likelihood of getting irritated, muscle and stomach cramp/pain, heartburn or diarrhea. In such event, the patient should be immediately taken to the hospital for prompt medical attention.

Fosamax Side Effects

Although most side effects associated with Fosamax are less serious, every unusual signs should be reported to the attending physician to be given immediate relief. These side effects include back pain, sluggishness or dizziness, headache, diarrhea, constipation, discomfort in the stomach due to heartburn or gas. Others include swelling and pain in the joint area, and of the hands and feet. In most cases, these side effects could be remedied by reducing the dosage of the medication.

Fosamax, however, is associated with some allergic reactions which could be threatening. These include swelling of the face, lips, throat, mouth or tongue. Swelling in those areas could most likely affect the respiration, as the swelling could reach until the airways. In an event of a chest pain, heartburn, or breathing difficulty, seek immediate medical help.
