"i am 51 year old on my 2nd implanon device; the first one replaced at 3 years as recommended.  i did gain some weight, but it&#039;s more a water retention thing.  i used to have very painful periods, which is why my gyn recommended it.  i&#039;m one of the lucky ones.  have not had any periods in 5 years, (spotted a bit the first month only) and plan to continue to use the implanon until i&#039;m completely menopausal (still perimenopausal).  the only reason i can&#039;t give it a 10 is whenever my blood pressure is taken in the left arm, the implant site &quot;pinches&quot;, solved by having bp taken on the other arm, but i was told i shouldn&#039;t be able to notice it.  cost a bit up front (even with insurance), but saved on prescription co-pays for 3 years so still cost effective."
