For vaginal administration of progynova capsules, is it necessary to remove the capsule shell before inserting it, or can the capsule be placed directly into the vagina?

Progestin capsules, also known as progesterone vaginal capsules, generally do not need to be opened before administration if they are enteric-coated or specifically designed for vaginal use; the entire capsule can be inserted directly. However, if the contents of the capsule need to be extracted for use, then the capsule must be opened. If in doubt, it is recommended to consult a healthcare provider in advance. Detailed explanations are as follows:

If the progesterone vaginal capsule is specifically formulated for vaginal administration, its shell is designed to dissolve within the vagina, allowing the medication to be gradually released as the shell dissolves. In this case, there is no need to open the capsule—simply insert the intact capsule into the vagina. Once the shell dissolves, the drug disperses evenly and takes effect, while also preventing direct contact between the medication and hands, thereby reducing the risk of contamination.

If the product instructions explicitly state that the gelatinous content or liquid inside the capsule should be extracted for use, or if the capsule shell is not made of a material designed to dissolve in the vaginal environment, then the capsule must be opened. The shell of such capsules may not dissolve properly in the vagina, and inserting them whole could impair drug release or even cause local discomfort. In these cases, the contents should be removed according to the instructions before vaginal administration.

Prior to using progesterone vaginal capsules, carefully read the package insert to confirm the correct method of administration. Wash your hands and the external genital area thoroughly before application to maintain hygiene. If you have any doubts about how to use the medication, do not adjust the method on your own—seek prompt advice from a doctor or pharmacist for clarification.
