I took reclast a year ago and I am due for bone density test next week. The first 72 hours were filled with chills, sweating flu like symptoms. I lost 5 lbs in 3 days. The remainder of the year were filled with severe headaches, muscle aches, sore throat, lots of hair shedding luckily not enough for others to notice. It was recommended that I have an infusion once a year. I swear I will never take this infusion again. I will let you know where I was before reclast and new results at end of month. I honestly don't know what's next because I am afraid now of all of these drugs.
