What to expect from bone-strengthening therapy for multiple myeloma

Multiple myeloma can weaken bone and increase the risk of pain, fractures and high calcium. Bone-strengthening medicines act on the cells responsible for bone breakdown. They are supportive care and are normally combined with treatment aimed at controlling myeloma. The medicine may be delivered by infusion or injection, with the schedule tailored to your response, kidney function and wider treatment plan.

Blood tests help the team decide whether treatment can proceed and whether the dose or timing needs review. Tell the team about kidney problems, previous jaw treatment, dental infection, or a planned extraction. These details can change preparation and follow-up.

Keep dental care regular and report mouth pain, swelling or loose teeth. Do not start calcium or vitamin D supplements unless your myeloma team recommends them, because calcium may already be high. Follow the fluid plan provided for your kidneys and treatment. Use walking aids or other support if advised, and ask before lifting or exercising through bone pain. Record changes in pain, height, posture, walking or strength.

Seek emergency care for new leg weakness, numbness, difficulty walking, loss of bladder or bowel control, or severe back pain. These symptoms may indicate spinal pressure. Call promptly for sudden severe pain after a minor movement, inability to bear weight, confusion, persistent vomiting, extreme thirst or reduced urine. A fever or new infection around a dental site also needs rapid advice.

Ask how your myeloma treatment and bone medicine work together, what your kidney and calcium results mean, and whether dental review is needed. Clarify the infusion or injection schedule, supplement instructions, safe activity, pain relief and the number to call for new neurological symptoms.
