I just found this group. I have been on Tymlos for 19 months and have gained about 10 pounds of fat around my waist and abdomen. My doctor said it wasn’t a side effect but nothing I do results in losing more than a pound or two. Now I must decide which drug to use next and I’m pretty disgusted thinking I am going to continue to be so uncomfortable. Finding this forum has validated my thinking the weight gain is a drug side effect.
