@aspirecreative I did find this post from someone who had a 15 minute infusion and then a 45 minute infusion. This is exactly what I'm talking about.

"I am a 77 year old with osteoporosis. A little over a year ago I had six fractures in my spine (all I did was roll over on bed!). I took my first reclast infusion and wound up in the hospital for pain management. The pain was so intense it caused me to experience a mild heart attack. A year rolls around and the Dr insist I must have a a second infusion. This time I was uton pain meds BEFORE the infusion and instead of the normal 15 mins to do the infusion they administered it over 45 mins time frame. Not problems at all after the infusion! Wishing you all the best!!!"
