Alendronate 70mg tablets is a once-weekly prescription bisphosphonate medication used to treat and prevent osteoporosis. A pack of 4 tablets provides a one-month supply. It works by slowing down bone breakdown, which helps to increase bone density and significantly lower the risk of spine and hip fractures.
Because it can cause severe irritation to the food pipe (esophagus), this medicine has very strict administration rules that must be followed exactly.
Strict Instructions for Use
To ensure the medicine is safely absorbed and does not damage your throat, you must follow these specific steps:
-
Take it first thing in the morning: Take your single 70mg tablet as soon as you get out of bed for the day. Do not take it at bedtime or before getting up.
-
Take on a completely empty stomach: Swallow the tablet whole with a full glass (6 to 8 ounces) of plain water only. Do not use mineral water, coffee, tea, or juice, as these drastically reduce absorption [4.2].
-
Do not chew or crush: Swallow the tablet whole [4.2]. Chewing, sucking, or crushing it can cause severe mouth or throat ulcers [4.2].
-
Stay completely upright: Remain sitting or standing fully upright for at least 30 minutes after swallowing the tablet. Do not lie down or recline until after you have eaten your first food of the day. This keeps the medicine from refluxing into your esophagus.
-
Wait to eat or take other pills: Wait at least 30 minutes before having your first meal, coffee, tea, or taking any other medications or supplements.
Critical Safety Warnings
-
Esophageal Irritation: Stop taking the medication and seek immediate medical attention if you experience chest pain, new or worsening heartburn, or painful/difficult swallowing.
-
Calcium and Vitamin Supplements: While adequate calcium and Vitamin D intake is crucial for bone building, you must avoid taking these supplements within the same hour window as Alendronate, as they will block its absorption. Some doctors recommend waiting up to 4 hours before taking calcium pills.
-
Dental/Jaw Considerations: Tell your dentist that you are taking Alendronate before undergoing any invasive dental procedures (like extractions), as bisphosphonates carry a rare risk of jaw-bone complications (osteonecrosis).
-
Unusual Pain: Contact your doctor immediately if you develop unexplained thigh, hip, or groin pain, which can occasionally signal a rare type of stress fracture.
If You Miss a Dose
If you forget to take your weekly tablet on your regular morning, take it the next morning after you remember. Then, return to your regular scheduled day the following week. Never take two tablets on the same day to make up for a missed dose.
