minor Known Drug Interaction
7.4 Levothyroxine The bioavailability of alendronate was slightly decreased when BINOSTO and levothyroxine were co-administered to healthy subjects [see Clinical Pharmacology (12.3) ] .

Binosto is a medicine that helps make your bones stronger. It is used to treat osteoporosis in women after menopause and in men.
Levothyroxine is a medicine that replaces a hormone normally made by your thyroid gland. It is used when the thyroid doesn't make enough hormone on its own.
Binosto treats osteoporosis, a condition that weakens bones and makes them more likely to break. It helps to increase bone mass in both postmenopausal women and men who have osteoporosis. Using this medicine can lower your chance of having fractures, including hip and spine fractures. Talk to your doctor about how long you should take this medicine.
This medicine treats hypothyroidism, a condition where the thyroid gland doesn't make enough thyroid hormone. It can be used in adults and children, even newborns. Levothyroxine can also be used after surgery and radioiodine therapy for thyroid cancer to help lower thyroid-stimulating hormone (TSH) levels.
Binosto belongs to a class of drugs called bisphosphonates. It works by slowing down the breakdown of bone in your body. This helps to increase bone density and reduce the risk of fractures.
Levothyroxine provides a synthetic form of thyroxine (T4), which is the main hormone produced by the thyroid gland. Your body converts T4 into triiodothyronine (T3), the active form of the hormone. By providing T4, levothyroxine helps restore normal thyroid hormone levels in your body.

Binosto can cause problems with your esophagus. Follow the directions for taking it carefully. If you have new or worsening heartburn, pain when swallowing, or chest pain, stop taking Binosto and call your doctor. This medicine may also cause severe bone, joint, or muscle pain. If you develop these symptoms, stop taking Binosto and contact your doctor.
Thyroid hormones, including levothyroxine, should not be used for weight loss or to treat obesity. Using high doses can cause serious and life-threatening side effects, especially when taken with stimulant medicines.
Stop taking Binosto if you become pregnant. Bisphosphonates can stay in your bones for many years and could potentially harm the baby's skeleton.
Tell your doctor if you are pregnant or plan to become pregnant. Your levothyroxine dose may need to be adjusted during pregnancy. Levothyroxine passes into breast milk, but it is not expected to harm the baby.

How to Read This alendronate vs levothyroxine Comparison
alendronate is classified in the Bisphosphonate drug class, while levothyroxine sits within the Thyroid Hormone class. Drugs from different classes work through distinct mechanisms, so a head-to-head comparison illustrates trade-offs rather than equivalence. Both drugs are prescription-only, so a licensed provider must authorize use.
Adverse event totals above are pulled from the FDA's Adverse Event Reporting System (FAERS). For these top-ranked reactions alone, alendronate has 58,576 submissions while levothyroxine has 101,062. Those figures reflect cumulative reporting volume, not per-patient risk, so older, widely dispensed drugs typically look worse on count alone. These two drugs have a known minor interaction flagged in FDA labeling, attributed to taking these two drugs at the same time can prevent the body from absorbing enough alendronate into the system.. Serious warnings, pregnancy guidance, and contraindications can differ even when indications overlap.
A table cannot represent individual circumstances. Data here is sourced from FDA Structured Product Labels (SPL) and FAERS, both of which update as manufacturers and clinicians submit new information. This registry does not provide medical, treatment, substitution, or medication-change directions for alendronate or levothyroxine.
