Comments |
Those allergic to peanuts, beware: Prometrium uses a peanut oil medium. Compounding pharmacies supplying non-branded progesterone may also use peanut oil; ask them if you need to know. Some people call this drug progesterone USP/PharEu/BP (according to the local regulatory commission), to differentiate from progestins. In some countries the drug is simply referred to as progesterone. The largest fraction progesterone taken orally is destroyed in the digestive tract, which, along with the very short half-life, accounts for the high dosage in comparison to synthetics, and may also account for some of the variability in efficacy. |
