Tymlos is a daily injection. It's an anabolic bone building drug very similar to Forteo. It can be taken for up to to two years. There are three anabolics: Tymlos, Forteo and Evenity. Evenity is a monthly infusion and can be taken for up to one year. Tymlos and Forteo are daily injections (with a "pen", pretty easy to do). I wanted to build up my bone density before "maintaining", hence the anabolic first. They aren't as effective if you've been on Reclast or another bisphosphonate already (since bisphosphonates "coat" the bones the anabolic's don't work as well, but can still increase the density). Reclast is a strong bisphosphonate. Other bisphosphonates include Fosomax (Aledronate), Boniva, Etc. Another option is a Prolia shot every six months, it's very good at keeping individuals from fracturing UNTIL you need to come off of it (like all they eventually cause issues with long term continuous usage) - they have not yet found a safe way to stop taking it without experiencing a huge drop in density and likely fractures. I won't take Prolia until they find a way to come off of it safely or until I"m in my 80's when I am not as concerned with long term usage of it (I'm only 54 currently so it's a ways off). I did two years of Tymlos to build up my bone density before switching to a maintenance drug, now will do a reclast infusion to "lock in the gains" I've made on Tymlos - the current plan is reclast infusions for 3 years and then likely 4-5 years of no drugs until they see my bones starting to decline again (since bisphosphonates build up and stay in the system) and not yet known for beyond that, but hopefully there will be some new options by then!
