Fosamax (Alendronate) is generally given as a 70mg weekly tablet — compliance is better than with daily 10mg. It depends on the doctor's prescription. Do not change the dose yourself.

Take it immediately upon waking in the morning, on a completely empty stomach, with one full glass (200–250 mL) of plain water ONLY.

Yes — it is absolutely necessary. Food, coffee, juice, milk, or mineral water drastically reduce alendronate absorption. Do not take anything alongside it other than plain water. Taking it 30–60 minutes before food is mandatory.

Take it as soon as you remember within the same week. Then return to your regular day. Do not take two doses on the same day. If more than a week has passed, skip it and take the next dose on the next regular day.

Doctors generally prescribe it for up to 5 years. After that, they review and may consider a drug holiday. Use beyond 5 years increases the risk of atypical femoral fracture. Regular DEXA scans and follow-up are recommended.
