Yes, Centrum Ostocalcium may cause side effects such as constipation and acidity (indigestion or heartburn) in some people. If you experience this, take the tablet with food, drink plenty of fluids, and increase fibre intake. However, if constipation or acidity persists or worsens, talk to a doctor.

Ostocalcium Total provides calcium and vitamin D, which support bone health, but it does not relieve pain. Persistent leg and lower back pain may be caused by arthritis, nerve issues, or other musculoskeletal problems, so your mother needs to see a doctor for a proper evaluation. For pain relief, a doctor may recommend suitable painkillers, such as paracetamol or ibuprofen, or other treatments, depending on the underlying cause.
