Progestogen-only implant guideline from FSRH

Progestogen-only implant guideline from FSRH

This is an updated guideline from the FSRH on the progesterone-only implant, updated in Feb 21 (and was originally released in 2014).

There are a few bits that are new in this guideline:

  • There is updated advice around using ulipristal-acetate and the progesterone only implant.
  • There is also advice on using the implant into the 4th year.
  • Mefenamic acid can be used as an option if there is problematic bleeding.
  • The position for implantation has been updated (as per previous communications from the FSRH).
  • They have also released an excellent Quick Reference Guide ( This is the first time that I have seen these from the FSRH, but it is very good.

As always, there are some excellent tables within the full guidance that give advice on starting the implant, switching from or to alternative contraception and also on stopping the implant. I have not put these in this blog, but they are a very useful resource.

"LocumDeck does everything you want it to do in an instant and with audit trails.

I absolutely love the facility for receiving Locum's invoices and the facility for signing the Pension Forms electronically and they are then instantly sent with an audit trail! It is fabulous!

You are notified the moment a Locum GP adds availability which is just fantastic, I spend a lot of time just chasing agencies to see if they have availability, so to be notified the moment availability is advertised is a new concept and very welcome! I have no hesitation in recommending LocumDeck - it has already eased my workload!"
