What menopause societies list as similar doses

When a patch can't be found, prescribers sometimes move people to a gel or tablets. Three menopause societies publish tables of roughly similar doses. They don't fully agree, all three call the figures approximate, and only a prescriber can make the change.

Any change of brand, strength or form is a decision for your prescriber, and your pharmacist can check what they can order.
