How does this medication work? What will it do for me?
This is a combination medication that contains alendronate and cholecalciferol. It is used to treat osteoporosis for postmenopausal women and for men. Alendronate belongs to a family of medications known as bisphosphonates.
Alendronate increases the thickness of bone (bone mineral density) by slowing down the cells that usually break down bone (osteoclasts). This allows the cells that build bone (osteoblasts) to work more efficiently. By making bones stronger, alendronate can help to reduce the incidence of osteoporosis-related fractures.
Cholecalciferol, also called vitamin D3, is a vitamin that is needed for calcium absorption and healthy bones.

How should I use this medication?
The recommended dose of alendronate - cholecalciferol is one tablet once weekly. The overall appropriate dosage of alendronate - cholecalciferol for you is determined by your doctor and is based on how much vitamin D you require.
The tablet should be taken first thing in the morning when you get up, and at least half an hour before you take your first meal, beverage, or other medication of the day. To reduce the risk of irritating the throat or esophagus, take the tablet with a full glass (250 mL) of plain water only. If your normal drinking water is classified as "hard water," it may decrease the absorption of this medication and you should consider taking it with distilled water.
After swallowing, do not lie down until 30 minutes have passed and you have eaten your first meal of the day. Do not take this medication at bedtime or before getting up in the morning. Swallow the tablets whole. Do not chew or suck on the tablets.

Are there any other precautions or warnings for this medication?
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Atypical femur fracture: There is evidence that long-term use of this type of medication may contribute to a type of rare fracture of the long bone in the thigh (femur) without any form of trauma.
If you experience new or unusual pain in the groin, hip, or thigh area, contact your doctor as soon as possible.
Bone, joint, and muscle problems: Rarely, people taking this medication experience severe bone, joint, or muscle pain. This usually goes away when the medication is stopped.
Calcium and vitamin D: Calcium and vitamin D are important for bone growth and strength. You may need to take calcium or additional vitamin D supplements to get the best effect from alendronate if you are not getting enough from your diet. Your doctor may test you for low calcium levels or vitamin D deficiency before you start taking alendronate-cholecalciferol.
Effects on the esophagus: Alendronate may irritate the lining of the esophagus (the passage from the throat to the stomach). In some cases, these effects have been severe and have required hospitalization. Stop taking the medication and contact your doctor immediately if you suddenly experience problems swallowing, find it painful to swallow, develop pain behind the sternum (breastbone), or have new or worsening heartburn.
To reduce the risk of irritation of the esophagus, swallow this medication with a full glass of plain water first thing in the morning when you get up. Do not lie down until 30 minutes have passed and you have eaten your first meal of the day. Do not chew or suck on the tablet, as this may lead to ulcers in the mouth or throat. Do not take this medication at bedtime or before getting up for the day.
Effects on the stomach and intestines: Rarely, people taking this medication have developed ulcers of the stomach or intestines. If you have stomach problems, such as ulcers and severe indigestion, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Get immediate medical attention if you have symptoms of a stomach or intestinal ulcer, such as nausea, vomiting, abdominal pain, loss of weight or appetite, black or bloody stools, or vomiting blood.
Eye inflammation: Some people who take alendronate experience symptoms of eye inflammation. If you experience swelling, redness, warmth, or sensitivity to light, contact your doctor as soon as possible.
Jaw problems: Rarely, alendronate may cause severe jaw problems associated with delayed healing and infection, especially for people with cancer or after tooth extractions. If you experience any pain in the jaw, especially after having a tooth removed, contact your doctor immediately.
Kidney function: Alendronate is removed from the body by the kidneys. If you have reduced kidney function or kidney disease, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Pregnancy: This medication has not been studied for use by pregnant women and therefore should not be taken during pregnancy. If you become pregnant while taking this medication, contact your doctor immediately.
