Strategies for reducing HRT doses gradually (2)

Using a lower dose HRT

  • a lower dose of the existing HRT can be used or change to a lower strength brand. This lower dose can be used for 2 -3 weeks, then you should alternate the pills with one day on and one day off, then one pill followed by two pill-free days and so on until the reduction is complete

Cutting HRT pills in half

  • some HRT brands (eg, Trisequens) can be cut in half and the regimen above for lowering the dose followed.

Using a patch with reducing doses

  • the use of the matrix estrogen patch can be an effective way of reducing HRT. Small increments can be cut off the patch each week so lesser amounts of HRT are applied. This may be easier for some women than reducing oral HRT doses
