CHILD
- Alendronate is not indicated for use in pediatric patients. The safety and
efficacy of alendronate sodium were examined in a randomized, double-blind,
placebo-controlled two-year study of 139 pediatric patients, aged 4-18 years, with
severe osteogenesis imperfecta (OI).

- In a pharmacokinetic study, 6 of 24 pediatric osteogenesis imperfecta patients who
received a single oral dose of alendronate sodium 35 or 70 mg developed fever,
flu-like symptoms, and/or mild lymphocytopenia within 24 to 48 hours after
administration.

RENAL IMPAIRMENT
- ( 8.4 ) Alendronate sodium is not recommended in patients with renal impairment
(creatinine clearance <35 mL/min).
Source: US FDA label for alendronate (Alendronate), section 'use in specific
populations', retrieved 2026-08-29
- No overall differences in efficacy or safety were observed between these patients
and younger patients, but greater sensitivity of some older individuals cannot be
ruled out. 8.6 Renal Impairment Alendronate sodium is not recommended for patients
with creatinine clearance less than 35 mL/min.
Source: US FDA label for alendronate (Alendronate), section 'use in specific
populations', retrieved 2026-08-29
- No dosage adjustment is necessary in patients with creatinine clearance values
between 35-60 mL/min [see Clinical Pharmacology (12.3) ] . 8.7 Hepatic Impairment
As there is evidence that alendronate is not metabolized or excreted in the bile,
no studies were conducted in patients with hepatic impairment.

HEPATIC IMPAIRMENT
- No dosage adjustment is necessary in patients with creatinine clearance values
between 35-60 mL/min [see Clinical Pharmacology (12.3) ] . 8.7 Hepatic Impairment
As there is evidence that alendronate is not metabolized or excreted in the bile,
no studies were conducted in patients with hepatic impairment.

PREGNANCY
- Risk Summary Available data on the use of Alendronate sodium in pregnant women are
insufficient to inform a drug-associated risk of adverse maternal or fetal
outcomes.

- Discontinue Alendronate sodium when pregnancy is recognized.

- In animal reproduction studies, daily oral administration of alendronate to rats
from before mating through the end of gestation or lactation showed decreased
postimplantation survival and decreased pup body weight gain starting at doses
equivalent to less than half of the highest recommended 40 mg clinical daily dose
(based on body surface area, mg/m 2 ).

BREASTFEEDING
- Risk Summary It is not known whether alendronate is present in human breast milk,
affects human milk production, or has effects on the breastfed infant.
Source: US FDA label for alendronate (Alendronate), section 'nursing mothers',
retrieved 2026-08-29
- The developmental and health benefits of breastfeeding should be considered along
with the mother’s clinical need for alendronate sodium and any potential adverse
effects on the breastfed child from alendronate sodium or from the underlying
maternal condition.
