Hello! They prescribed Despantol at night. Is it normal for this to leak? I'm not sure if I'm inserting it correctly. In the morning when I wake up, my underwear is wet. They told me to insert it before the cauterization. I read online that suppositories should be stopped three days before the cauterization. Please share your experience.
