FAQ

A prescription is required to buy alendronate from local pharmacies in Canada. However, our store policy allows you to order these alendronate tablets without a prescription and have them sent by mail.

It is generally best to keep alendronate tablets in their original container until use, since it protects them from moisture and light and keeps the strength and directions identifiable. If using a pill organizer, only transfer the tablet for the near term and keep the organizer dry, tightly closed, and clearly labelled.

The regulatory status of the exact product supplied cannot be confirmed from the available product details. Alendronate is a prescription drug in Canada, and Fosamax products containing alendronate are listed in Health Canada's Drug Product Database, but that does not establish the approval status of a particular supplied manufacturer or package.

Alendronate should be avoided during pregnancy. It should also be avoided while breastfeeding because it is not known whether it passes into human milk, and its effects on a nursing infant have not been established. Someone who becomes pregnant or is breastfeeding should have their treatment reviewed by their prescriber.

Description

General Information

Fosamax (Alendronate) is a medicine of the bisphosphonate pharmacological class. It is frequently used to treat disorders affecting the bones, such as osteoporosis. Osteoporosis is characterized by bone thinning, which increases the risk of fractures.

Fosamax prevents osteoclasts-cells that tear down bone tissue-from doing their job. Alendronate helps maintain or improve bone density by slowing down bone resorption, lowering the risk of fractures.

It is usually taken orally, and you must adhere to your doctor's instructions and the recommended dosage. It is important to share any concerns or questions you may have with your doctor because, like any drug, there is a chance of side effects.

Fosamax Ingredients

Alendronate sodium is the primary component. This medication, a bisphosphonate, is used to treat osteoporosis, among other bone disorders. Alendronate prevents osteoclast activity, which is the action of the cells that degrade bone tissue. Alendronate helps people with illnesses that cause bone loss by slowing down the resorption of bone, which increases bone density and lowers the risk of fractures.

Usually, alendronate sodium is used in place of Alendronate. Oral administration is recommended for the sodium salt version.

How the Medicine Looks like

Tablets for Oral Use

Tablets: white round uncoated (5 mg), white oval wax polished (10 mg), white oval uncoated (35 mg), white triangular uncoated (40 mg), and white oval uncoated (70 mg) pills. Different brands may produce pills that look different.

Oral Remedy

Raspberry-flavored, colorless, and clear oral solution (70 mg/bottle).

Applications

Fosamax is used to prevent osteoporosis in women who have gone through menopause. Alendronate can also be used to treat osteoporosis in men and women who have it due to medications or natural causes. Fosamax is also used to treat bone-related Paget's disease. It stops bone deterioration and raises bone density (thickness) to make bones stronger and less prone to breaking.

How to Take 

Dosage Strength Formulation Typical Dosage Schedule
5 mg Tablet Once daily or once weekly
10 mg Tablet Once daily or once weekly
35 mg Tablet Once weekly
70 mg Tablet Once weekly

Depending on the prescribed dosage, tablets should be taken once daily or once every week. They should be taken with a full glass of water (6-8 ounces) first thing in the morning. Wait at least thirty minutes after taking Alendronate before consuming food, liquids, or other medications. This includes vitamins, antacids, and calcium supplements. The best results from the medicine are obtained when the stomach is empty. Swallow the pills whole; do not chew or suck on them. After taking this medication, stay off the bed for at least thirty minutes. After taking the oral solution, sip at least 1/4 of a cup (2 oz or 60ml) of water.

Precautions

Fosamax should not be taken if you are expecting or nursing a baby. It should also be avoided if you have kidney illness or issues with your stomach or intestines. Inform your physician if you experience any of these issues or if you find it difficult to remain upright for at least thirty minutes at a time.

It is not recommended to take Fosamax along with any other medications. When taking these pills, avoid taking antacids or any other prescription or over-the-counter drugs that contain aluminum, calcium, iron, or magnesium. If you must take other prescriptions, wait at least one to two hours after taking Alendronate before taking them. If you are unsure of how or when to take your drugs, speak with your pharmacist or doctor.

Your doctor could advise you to take calcium and vitamin D supplements in addition to Fosamax. If you do, remember to take these vitamins later in the day than you take Risedronate. Avoid taking calcium and vitamin D if you have high blood calcium levels.

Store in a tightly closed container at room temperature. Keep out of children's reach.

For further information about this drug, please call your doctor, pharmacist, or nurse.

Restrictions

Certain circumstances or contraindications exist for alendronate use; therefore, it might not be appropriate for everyone. 

Hypersensitivity: Fosamax or any of its constituents should not be used by anyone with a known hypersensitivity or allergy.

Abnormalities of the esophagus: Fosamax may cause irritation to the esophagus. As a result, people with esophageal emptying disorders such as strictures or achalasia should use the medicine with caution.

Inability to stand or sit upright: Alendronate should not be taken by patients who cannot stand or sit upright for at least thirty minutes. Maintaining an upright position both during and after taking the drug is crucial to lowering the risk of esophageal irritation.

Reduced renal function: Since the kidneys eliminate Fosamax, people with significant renal impairment may need to change their dosage or not take the drug.

Deficiency in calcium and vitamin D: The medicine's efficacy depends on a sufficient intake of these nutrients. People with deficiencies can require supplements.

Before beginning treatment or any new medicine, you should always tell your healthcare practitioner about your medical history, including any current problems or medications you are taking. This will make the treatment more suitable and safe for you.

It's critical to get emergency medical assistance right away if you suspect an overdose or if you suffer symptoms like nausea, indigestion, chest discomfort, or stomach pain, as well as trouble swallowing. Severe side effects, including ulceration and esophageal irritation, might result from using too much Fosamax.

If someone overdoses, they shouldn't induce vomiting unless a medical practitioner instructs them to do so. Supportive care will be given, along with precautions to safeguard the gastrointestinal system and esophagus.

Adhere to the suggested administration instructions and maintain the authorized Alendronate dosage. Contact your healthcare practitioner right away if you have questions regarding your medication or if you inadvertently take more than the recommended amount.

How to Store

Keep Fosamax at room temperature and out of direct sunlight. Keep it away from anything hotter than 25°C (77°F).

Preserve the drug in its original container and shield it from moisture. Keep it out of the bathroom and other moist areas.

This medicine and other drugs should be kept out of the reach of kids and animals. To avoid unintentional consumption, think about utilizing childproof containers.

Verify the medicine's expiration date on the container. It should not be used after the expiration date.

Whenever your pharmacist or healthcare practitioner gives you particular storage instructions, always heed their advice. Speak with your pharmacist or healthcare provider if you need help storing your medication or if it has been exposed to adverse conditions. Never use medication that is broken, discolored, or smells strange.

Customer questions

Asked by Alyssa, Iqaluit, Canada

I live in Iqaluit. How can I find out whether alendronate tablets can be shipped to my address before I place an order?

Answered by Support team

Destination availability for remote addresses is not confirmed in advance. Enter your full Iqaluit address and postal code during checkout to verify whether shipping is available for your order.

Asked by Daniel, Windsor, Canada

My order has arrived. Where do I check that I received the alendronate strength I selected?

Answered by Support team

Check the package label for the active ingredient, "alendronate," the strength in mg, and the dosage form, tablet. Also compare the manufacturer name, lot number, expiry date, and tablet imprint if one is present; do not use the tablets if the ingredient, strength, or form does not match your order.

Asked by Marianne, Ottawa, Canada

My package was delivered in Ottawa during a cold spell. What should I inspect before I take the alendronate tablets?

Answered by Support team

Check that the package is intact and dry and that the tablets are not cracked, discoloured, or otherwise damaged. Store them at 20°C to 25°C in a well-closed container, in a dry place away from light; because the actual temperature exposure and duration are unknown, have any compromised package checked before use.

Asked by Graham, Winnipeg, Canada

I take alendronate weekly and have developed a new dull ache in my thigh. Could that be important?

Answered by Support team
Medical reviewed by Reynard Sparks

Yes. New or persistent thigh, hip, or groin pain can occasionally be a warning sign of an unusual femur fracture in people taking bisphosphonates. Contact your prescriber promptly for assessment before taking further doses.
