Alendronic Acid + Vitamin D3: Brands, Price & Uses in Bangladesh

Alendronic Acid + Vitamin D3 is indicated for the following established uses:

• Treatment of osteoporosis in postmenopausal women - reduces the incidence of vertebral, hip, and other fractures while increasing bone mineral density.
• Treatment to increase bone mass in men with osteoporosis.

Limitation of use: Alendronic Acid + Vitamin D3 should not be used as the sole therapy for correcting vitamin D deficiency; it is intended to provide a maintenance dose of vitamin D3 alongside the anti-resorptive effect of alendronic acid, not to treat established deficiency states, which require separate, higher-dose vitamin D repletion.

This fixed-dose combination is generally prescribed once weekly maintenance dosing after adequate calcium and vitamin D status has been confirmed, and is not intended as first-line therapy in patients whose baseline calcium or vitamin D levels have not been assessed.

Administration Instructions

Alendronic Acid + Vitamin D3 must be taken exactly as follows to ensure absorption and reduce the risk of esophageal irritation:

• Take first thing in the morning, at least 30 minutes before the first food, beverage, or other medication of the day.
• Swallow the tablet whole with a full glass (6-8 ounces) of plain water only - not mineral water, coffee, tea, juice, or milk.
• Do not chew or suck the tablet, and do not take it at bedtime or before getting out of bed for the day.
• Remain in a fully upright position (sitting or standing) for at least 30 minutes after taking the dose, and until after the first food of the day.
• If a dose is missed, take it the morning after it is remembered; do not take two doses on the same day - resume the original once-weekly schedule.
• Ensure adequate dietary calcium and vitamin D intake; correct any hypocalcemia before starting therapy (see Contraindications and Precautions).

Common side effects of Alendronic Acid + Vitamin D3 include:

• Gastrointestinal effects: abdominal pain, distension, acid regurgitation, dyspepsia, nausea, diarrhea, or constipation.
• Musculoskeletal pain (bone, joint, or muscle pain), which can occasionally be severe.
• Headache.
• Esophageal irritation or reflux symptoms.

Less common but serious effects include severe esophageal reactions (esophagitis, esophageal ulcer or erosion), osteonecrosis of the jaw, and atypical femur fractures - see Precautions and Warnings for details. Hypersensitivity reactions (rash, angioedema, and rarely severe skin reactions) have also been reported.
