ALENDRONIC ACID 10 mg tablets should be taken on an empty stomach immediately with a large glass of tap water at least half an hour before the first intake of food, drink or any other medication. Other beverages (including mineral waters), foods and medicines may decrease the absorption of alendronate (see section on interactions).

. ALENDRONIC ACID EG 10 mg, tablet should not be taken at bedtime or before sunrise.
. Patients treated should be supplemented with calcium and vitamin D if their dietary intake is inadequate (see section on warnings and precautions for use).
- Use in elderly patients:
Clinical studies have not revealed any age-related differences in the efficacy and safety profiles of alendronate. Therefore no dosage modification is necessary in elderly patients.
- Use in case of renal insufficiency:
No dosage modification is necessary in patients with glomerular filtration rate (GFR) greater than 35 ml / min. Due to a lack of experience, alendronate is not recommended for patients with GFR <35 ml / min.
- Use in case of hepatic insufficiency:
No dosage modification is necessary.
- Use in children:
Alendronate has not been studied in children and should not be given to them.

Against indications

- Hypersensitivity to alendronate, other bisphosphonates or any of the excipients.
- Diseases of the esophagus and other factors that delay esophageal transit such as stenosis and achalasia.
- Inability to stand or sit for at least 30 minutes.
- Hypocalcemia.
See section warnings and precautions for use.
- Alendronate is not recommended in patients with renal impairment characterized by a glomerular filtration rate (GFR) less than 35 ml / min (see section dosage and method of administration).
- Use in children: alendronate has not been studied in children and should not be given to them.
- Due to the presence of lactose, this drug is contraindicated in case of congenital galactosemia, glucose-galactose malabsorption syndrome or lactase deficiency.
- Use during pregnancy: information on the use of alendronate in pregnant women is insufficient. Animal studies have shown effects on fetal ossification at high doses. Alendronate administered during pregnancy in rats caused obstructed labor due to hypocalcemia. Because of its indication, alendronate should not be used during pregnancy.
- Use during breastfeeding: It is not known if alendronate is excreted in human breast milk. Given its indication, alendronate should not be used by women who are breastfeeding.

Frequent (> = 1/100, <1/10) : headache.
- Eye disorders:
Rare (> = 1/10000, <1/1000) : uveitis, scleritis.
