Gynecological injections to stop bleeding include tranexamic acid, phenolsulphonamide, thrombin, vitamin K, and so on. It is necessary to find out what causes the bleeding, and give reasonable treatment for the cause in order to have an effective effect of stopping bleeding. If the bleeding is caused by intrauterine residue, only the use of hemostatic drugs is ineffective, and should be promptly performed to clear the uterus; because the ring does not adapt to the bleeding caused by the position of the downward shift, should be promptly removed surgically. If the bleeding is caused by uterine fibroids or endometriosis, surgery should be considered if the fibroids are large. If the bleeding is caused by hormonal imbalance, you can use drugs such as combined estrogen tablets, progesterone, deoxyprogesterone ethinyl estradiol tablets, etc.; if it is purely gynecological hemostasis, you can use phenolsulfonyl ethylamine, aminoglycolic acid and other hemostatic drugs. All of the above drugs should be used under the guidance of a doctor, and should not be used blindly on their own. It is recommended to further clarify the cause of bleeding, targeted treatment, to avoid delaying the condition, and timely to the regular hospital.
