Frequently asked questions
Why do I feel like I have flu after the drip?
This is common after the first infusion and settles within a few days. Paracetamol can help — ask your doctor.
Why only once a year?
It stays in the bone for a long time, so one infusion protects for about a year in osteoporosis.
Do I need dental checks?
Yes — rarely it can cause jaw-bone problems, so good dental care is important.
