I'd read that too DuMondeB.
Blockers are still off licence for precocious puberty and as part of a cancer treatment pathway.
However a key difference is that it is not used as a long term solution.
The plan is always that these children will, at the soonest appropriate time, stop the blockers and enter puberty.
As far as I'm aware there are no reputable studies into the long term side effects for even transient usage of these drugs.
In the case of GD the impact is greater in so far that nearly all children who take them move on to taking cross sex hormones and thus never go through a natural puberty at all.
Therefore there is a double whammy at play here. The lack of knowledge wrt the side effects these drugs have in and of themselves plus the impact of puberty denial.
Saying these drugs represent a "safe" and "reversible" pause button is highly disingenuous.
We simply don't know what the long term consequences are - other than the fact that those who take blockers almost always go on to transition using CSH's whilst the reverse is true for those who don't.
That fact alone should be a red flag about their use when treating GD.
