Hi Robin – welcome to the forum!
I’ve now had my 2nd dose of Zolendronic Acid/Zometa and my experience has similarities to those of the 1st reply (above) to the OP. The first time the ‘infusion’ took place over 15 mins and I was fine for just u der 36 hrs. Then – in the space of about 90 seconds – it felt as though someone had worked me over with a sledgehammer!! Total body ache, felt v. unwell and kidney pain as well (which was my biggest concern). Symptoms gradually eased off over 2 days, with the kidney pain the last to disappear under a deluge of drinking water! Second dose was last week – on the advice of a CNS I got them to take 30 mins over the I fusion. Symptoms again arrived about 30 hrs later but considerably milder and lasted only 1 day. Was already pre-loading on water so kidneys weren’t too bad.
Overall it hasn’t been a fun experience, but even if the symptoms had stayed as bad as the first session I wouldn’t hesitate to keep going with them.
I hope you have an easy ride!
Nick
