Risk of severe bone, joint, or muscle pain; discontinue therapy in patients who experience severe symptoms of pain; avoid use in patients with history of these symptoms in association with bisphosphonate therapy
Possible increased risk of atypical subtrochanteric and diaphyseal femur fractures; may consider discontinuing therapy after 3-5 years in patients at low-risk for fracture; following discontinuation, re-evaluate fracture risk periodically; consider periodic reevaluation of need for continued bisphosphonate therapy, particularly if treatment lasts >5 years; patients with new thigh or groin pain should be evaluated to rule out a femoral fracture
Use effervescent tablet with caution in sodium-restricted patients (tablet contains 603 mg sodium, equivalent to approximately 1532 of NaCl or salt)
Drug interaction overview
Calcium supplements/antacids
- Coadministration with calcium, antacids, or oral medications containing multivalent cations will interfere with absorption of alendronate
Aspirin
- In clinical studies, the incidence of upper gastrointestinal adverse events was increased in patients receiving concomitant therapy with daily doses of alendronate sodium greater than 10 mg and aspirin-containing products
Nonsteroidal anti-inflammatory drugs (NSAIDs)
- Use with caution
- In a clinical study which a majority of patients received concomitant NSAIDs, the incidence of upper gastrointestinal adverse events was similar in alendronate-treated group compared to placebo
Levothyroxine
- Bioavailability of alendronate was slightly decreased when alendronate and levothyroxine were coadministered to healthy subjects
Pregnancy & Lactation
Pregnancy
Available data on use in pregnant women insufficient to inform a drug-associated risk of adverse maternal or fetal outcomes; discontinue when pregnancy recognized.
Animal data
- In animal reproduction studies, daily oral administration to rats from before mating through end of gestation or lactation showed decreased postimplantation survival and decreased pup body weight gain starting at doses equivalent to less than half of highest recommended 40 mg clinical daily dose (based on body surface area, mg/m2)
- Oral administration to rats during organogenesis resulted in reduced fetal ossification starting at doses 3 times clinical daily dose of 40 mg;
- No similar fetal effects observed in pregnant rabbits dosed orally during organogenesis at doses equivalent to approximately 10 times the 40 mg clinical daily dose
- Delayed or failed delivery of offspring, protracted parturition, and late pregnancy maternal and fetal deaths due to maternal hypocalcemia occurred in rats at oral doses as low as one tenth the 40 mg clinical daily dose
- Bisphosphonates are incorporated into the bone matrix, from which they are gradually released over a period of years; based on mechanism of action of bisphosphonates, there is a potential risk of fetal harm, predominantly skeletal, if a woman becomes pregnant after completing a course of bisphosphonate therapy
- Impact of variables such as time between cessation of bisphosphonate therapy to conception, particular bisphosphonate used, and route of administration (intravenous versus oral) on risk not studied
Lactation
Not known whether drug present in human breast mild, affects milk production or has effects on infants
Consider developmental and health benefits of breastfeeding along with mother’s clinical need for therapy and any potential effects on breastfed child from drug or underlying maternal condition
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology

Alendronate may cause allergic reactions , which can be serious. Stop taking alendronate and get help right away if you have any of the following symptoms of a serious allergic reaction. Breathing problems or wheezing Racing heart Fever or general ill feeling Swollen lymph nodes Swelling of the face, lips, mouth, tongue, or throat Trouble swallowing or throat tightness Itching, skin rash, or pale red bumps on the skin called hives Nausea or vomiting Dizziness, feeling lightheaded, or fainting Stomach cramps Joint pain Esophagus Problems. Taking alendronate by mouth may irritate the esophagus or upper part of your gastrointestinal (GI) tract. This irritation can be worse in people who already have stomach or esophagus problems. In some cases, it can lead to problems such as ulcers, bleeding, or tears in the esophagus, which may require hospitalization. Stop taking alendronate and call your healthcare provider right away if you have any of the following symptoms. Trouble or pain while swallowing Chest pain New or worsening heartburn Low Calcium Level (Hypocalcemia). Alendronate can cause low calcium levels, also known as hypocalcemia , which can be serious. Decreased calcium levels can cause a rare dangerous heart rhythm problem called QT prolongation and torsade de pointes. Some people have a higher risk of this, including people who are older, have other people in their family who have had these conditions, have low potassium or magnesium, or who take some medicines for other heart rhythm problems. Call your healthcare provider if you have any of the following symptoms. Changes in your heart rate or rhythm, such as fast or skipping heartbeat Fainting Numbness, tingling, or burning sensation in your arms, feet, or face (paresthesia) Muscle pain, spasms, twitching, or cramps Seizures Severe Pain in the Bones, Joints, or Muscles. Alendronate may cause severe pain in the bones, joints, or muscles ( musculoskeletal pain ). The pain can be severe enough that it could be difficult to carry out normal activities. Call your healthcare provider if you experience severe pain while on alendronate. Severe Jawbone Problems ( Osteonecrosis ). Alendronate can rarely cause severe jawbone problems, also called osteonecrosis of the jaw. In this condition, your jawbone may get damaged due to reduced blood flow. You may be at higher risk if you are undergoing certain dental procedures (such as a tooth extraction or dental implants), if you have poor oral health, or if you have cancer or certain other conditions. You may be told to see a dentist before starting alendronate and to practice good mouth care. Call your healthcare provider right away if you experience any of the following symptoms of jaw osteonecrosis. Jaw pain or discomfort Mouth sores Loose teeth Unusual Thigh Bone Fractures. Alendronate may cause an increased risk for fractures in your thigh bone, even with a light force. Call your healthcare provider if you experience new or unusual pain in your thigh, hip, or groin.
