Witepsol H15 is an inert hard fat used as base for drug release from suppositories progesterone.
The quantities normally used are 1.1275 g for 125 mg suppositories, 1.15 g for 250 mg oral medicines (1).
The only problem with this grease is its oxidation when left in contact with air for a long time. It is therefore necessary to use the drugs that contain it in a short time.
