The safety of both oestrogen and progestogen depends on the mode of administration, as well as the dosage.
Professor Bronwyn Stuckey, a clinical endocrinologist and the medical director at the Keogh Institute for Medical Research in WA, discusses the dangers of troches in the following video.
“Yes, it is a problem,” she says. “We shouldn’t be prescribing troches. Troches haven’t gone through the rigorous testing to look at the balance oestrogen and progesterone in a similar way that commercial preparations have.
“The most worrying problem is that the progesterone in the troche will not be sufficient to protect the endometrium against the oestrogen.”
