Menstruation is a unique physiological condition for women, and in order to pass this special period peacefully, many women spend a lot of energy and time to understand the diet, exercise and other menstrual contraindications, and medication contraindications should also be taken seriously. During menstruation, women should avoid taking hormonal drugs, anticoagulants or hemostatic drugs, diet pills and vaginal plugs. If there is a need for treatment, it should be taken under the guidance of a doctor. 1. External vaginal medication Many patients with gynecological diseases such as vaginitis need vaginal plugs, but they should stop during menstruation. During menstruation, women have a relaxed cervical opening and their defenses are significantly reduced. At this time, it is important to avoid topical medications in the vaginal route and not to do vaginal douching with lotions to avoid the possibility of upstream infection. Generally, vaginal administration of medication is done at the time of 3-7 days after menstruation, otherwise it may lead to ineffective medication or have an impact on the judgment of the disease. If vaginal plugs come after menstruation, there is no need to be overly nervous, just stop the vaginal medication immediately. 2. Hormonal drugs, especially internal hormonal drugs Hormones are widely used and have significant therapeutic effects. Hormonal drugs can be divided into glucocorticoids, adrenocorticosteroids, norepinephrine, progesterone, estrogen and androgens. Hormonal drugs such as birth control pills not only disrupt the endocrine system, but also cause abnormal menstrual cycle, menstruation time and blood volume. And this side effect will not only occur during menstruation, but also may spread to other periods, so hormonal drugs must be under the guidance of a doctor, and inform the doctor in detail of the menstrual cycle and other circumstances. 3, aspirin and other anticoagulants or hemostatic drugs Anticoagulants, by affecting certain coagulation factors in the clotting process, thus preventing the clotting process, many patients with cardiovascular diseases need to take medication for life. Commonly used anticoagulants include heparin, coumarins, and antiplatelet agents (aspirin, pentoxifylline, etc.). The use of anticoagulants or hemostatic drugs during menstruation (Enola blood, vitamin K, etc.) may lead to increased menstrual flow, heparin, coumarin class may also cause hemorrhage, so female patients should consult a professional doctor before taking anticoagulants, hemostatic drugs, especially the menstrual flow is not small women, but also careful to use strong hemostatic effect of traditional Chinese medicine or proprietary Chinese medicine. 4, diet pills Diet pills often contain appetite suppressant ingredients, if taken during the period, may lead to menstrual disorders, endocrine disorders, panic, anxiety and other symptoms, which will endanger health.
