Brief summary

This study will aim to determine whether giving a steroid tablet (dexamethasone) for three days after a zoledronic acid infusion will reduce the risk of a side effect known as the acute phase response, which can cause fever, nausea, muscle pains and headache, compared to giving an inactive (placebo) tablet. It is possible that a three-day course of a commonly used steroid, dexamethasone, could reduce the number of patients experiencing this reaction..

Interventions

Participants will be randomized to receive either 3 days of dexamethasone tablets or 3 days of placebo tablets. The group randomized to receive the intervention will receive dexamethasone 4 mg orally administered 1-4 hours prior to the zoledronate infusion and then once daily in the morning for two further days. The method of administration will be an oral tablet.
