Before taking alendronate,
tell your doctor and pharmacist if you are allergic to alendronate or any other medications.
tell your doctor and pharmacist what prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking or plan to take. Be sure to mention any of the following: angiogenesis inhibitors such as bevacizumab (Avastin), everolimus (Afinitor, Zortress), pazopanib (Votrient), sorafenib (Nexavar), or sunitinib (Sutent); aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen (Advil, Ibu-Tab, Motrin, others) and naproxen (Aleve, Naprelan, Naprosyn, others); cancer chemotherapy; or oral steroids such as dexamethasone, methylprednisolone (Medrol), and prednisone (Rayos). Your doctor may need to change the doses of your medications or monitor you carefully for side effects.
if you are taking any other medications including supplements, vitamins, or antacids by mouth, take them at least 30 minutes after you take alendronate.
tell your doctor if you are unable to sit upright or stand upright for at least 30 minutes and if you have or have ever had a low level of calcium in your blood or any problems with your esophagus. Your doctor may tell you that you should not take alendronate.
tell your doctor if are undergoing radiation therapy and if you have or have ever had anemia (condition in which the red blood cells do not bring enough oxygen to all the parts of the body); a low level of vitamin D in your body; difficulty swallowing; heartburn; ulcers or other stomach problems;cancer; any type of infection, especially in your mouth; problems with your mouth, teeth, or gums any condition that stops your blood from clotting normally; or dental or kidney disease.
tell your doctor if you are pregnant or are breast-feeding. Also tell your doctor if you plan to become pregnant at any time in the future, because alendronate may remain in your body for years after you stop taking it. Call your doctor if you become pregnant during or after your treatment.
you should know that alendronate may cause osteonecrosis of the jaw (ONJ, a serious condition of the jaw bone), especially if you have dental surgery or treatment while you are taking the medication. A dentist should examine your teeth and perform any needed treatments, including cleaning or fixing ill-fitted dentures, before you start to take alendronate. Be sure to brush your teeth and clean your mouth properly while you are taking alendronate. Talk to your doctor before having any dental treatments while you are taking this medication.
you should know that alendronate may cause severe bone, muscle, or joint pain. You may begin to feel this pain within days, months, or years after you first take alendronate. Although this type of pain may begin after you have taken alendronate for some time, it is important for you and your doctor to realize that it may be caused by alendronate. Call your doctor right away if you experience severe pain at any time during your treatment with alendronate. Your doctor may tell you to stop taking alendronate and your pain may go away after you stop taking the medication.
talk to your doctor about other things you can do to prevent osteoporosis from developing or worsening. Your doctor will probably tell you to avoid smoking and drinking large amounts of alcohol and to follow a regular program of weight-bearing exercise.
