Many mothers ask how to introduce glycerin suppositories and how quickly they work. The suppository should be inserted into the anus with the pointed part forward. The effect becomes apparent after 10-20 minutes, within half an hour at the latest. Glycerin-based suppositories are safe, so as long as your mucosa can tolerate them, you can use them as needed. The drug can become habit-forming, so it is not recommended to use it daily for more than 1 week.
