There may be cases where a woman has been taking medication without realizing she was pregnant, but as long as the pregnancy continues, there is no need to worry.<br>However,&nbsp;<strong>care should be taken with medications that have a high residual effect.<\/strong>&nbsp;It is possible that the drug&#8217;s ingredients remain in the body and may be taken after the fourth week of pregnancy. Drugs that have long-lasting effects include etretinate (a drug used to treat keratosis), ribavirin (an antiviral drug), and leflunomide (an antirheumatic drug). If there is a possibility that you are pregnant, avoid taking these medications.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"c2-2\"><span class=\"ez-toc-section\" id=\"Absolute_hypersensitive_periodweeks_4_to_7\"><\/span>Absolute hypersensitive period\/weeks 4 to 7<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>The most careful time to take medication is between&nbsp;<strong>the 4th and 7th weeks<\/strong>&nbsp;of pregnancy. During this time, important organs such as the baby&#8217;s central nervous system and heart are being developed, making them susceptible to the effects of medication. The<br>aforementioned highly teratogenic medications should be avoided during pregnancy. If you declare that you may be pregnant, medical institutions will not prescribe them.<br>Also, while it is rare for over-the-counter medications to cause birth defects, be sure to read the package insert carefully to see if it is okay to take the medication during pregnancy.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"c2-3\"><span class=\"ez-toc-section\" id=\"Relative_sensitivity_periodweeks_8_to_15\"><\/span>Relative sensitivity period\/weeks 8 to 15<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>During the 8th to 15th week of pregnancy, the palate, hands, feet, genitals, etc. are being formed.

However,&nbsp;<strong>since the medicines taken by pregnant women can also enter the baby&#8217;s body through the placenta, some medicines are known to cause fetal dysfunction.<\/strong>&nbsp;In particular, nonsteroidal anti-inflammatory drugs (NSAIDs) have the effect of constricting the baby&#8217;s ductus arteriosus, so it is generally recommended to avoid taking them.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"c3\"><span class=\"ez-toc-section\" id=\"If_you_are_taking_medication_due_to_illness\"><\/span>If you are taking medication due to illness<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"c3-1\"><span class=\"ez-toc-section\" id=\"Consult_your_doctor_as_soon_as_you_start_thinking_about_pregnancy\"><\/span>Consult your doctor as soon as you start thinking about pregnancy<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Some people may be taking medication for a long time due to chronic illness or while undergoing medical treatment.

If you find out you are pregnant, please consult with your doctor about whether you should continue taking the medication or switch to a different medication.

The following supplements may have a negative effect on the development of your baby, so you should be careful when taking them.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"c4-1\"><span class=\"ez-toc-section\" id=\"Vitamin_A_supplements\"><\/span>Vitamin A supplements<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Vitamin A is a nutrient that protects the skin, mucous membranes, and eyes. It is divided into carotenoids derived from plants and retinol derived from animals. Retinol in particular is easily accumulated in the body, and\u00a0<strong>it is known that excessive intake during early pregnancy increases the risk of causing birth defects in babies.<\/strong>\u00a0For the same reason, many people have heard that &#8220;it is better to be careful not to eat too much eel or liver, which contain a lot of animal-derived vitamin A, during pregnancy.&#8221; Since supplements are easily available at drugstores and online stores, self-management is important. If you are taking vitamin A supplements on a regular basis, try stopping the supplements and getting nutrients from meals such as green and yellow vegetables.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"c4-2\"><span class=\"ez-toc-section\" id=\"Isoflavone-containing_supplements\"><\/span>Isoflavone-containing supplements<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Isoflavones have a similar effect to female hormones. Although they are thought to be good for beauty, it is not recommended to take more isoflavones in supplements than necessary during pregnancy. During pregnancy, a woman&#8217;s body is already in a state where hormone balance is easily disturbed. If you\u00a0<strong>take too much isoflavone, your hormone balance will be further disturbed and it may affect the baby&#8217;s reproductive function<\/strong>. Although it is not clear how much is harmful, the Ministry of Health, Labor and Welfare has set the upper limit of the recommended intake of soy isoflavones at 75 mg\/day and the upper limit of additional intake in supplements at 30 mg\/day. Be careful not to take too much just because it is good for your body.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" width=\"600\" height=\"400\" src=\"\/nipt\/wp-content\/uploads\/2021\/12\/52c3255f955b1f7787c6c722e1931ef2.png\" alt=\"\u598a\u5a20\u521d\u671f\u306e\u85ac\u3068\u306e\u3064\u304d\u5408\u3044\u65b9\" class=\"wp-image-21181\"\/><\/figure><\/div>\n\n\n<h2 class=\"wp-block-heading\" id=\"c5\"><span class=\"ez-toc-section\" id=\"What_if_I_take_the_medicine_before_I_know_Im_pregnant\"><\/span>What if I take the medicine before I know I&#8217;m pregnant?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>There are also cases where the patient has taken the medicine before realizing that she is pregnant. If the medicine is taken during the early stages of pregnancy, when the effects of the medicine are a concern, it is still worrying. <\/p>\n\n\n\n<p>As mentioned above, there is certainly a period when the medicine is more likely to affect the baby. However, taking over-the-counter medicines several times during early pregnancy will not affect the development of the baby in most cases. Medicines that may cause birth defects are often not prescribed to women of childbearing age, so there is no need to worry too much. <\/p>\n\n\n\n<p>If you have taken medicine before realizing that you are pregnant,\u00a0<strong>first consult a doctor. Be<\/strong>\u00a0sure to tell your doctor exactly what type of medicine you have taken, the amount, and the period of use, and follow their instructions. Instead of worrying alone or getting excited or upset over information on the Internet, learning the correct information from an expert will help you calm down.<\/p>\n\n\n\n    <a href=\"\/nipt\/from-pregnancy-to-childbirth\/\" class=\"blog-card\">\n      <div class=\"blog-card-content\">\n          <div class=\"blog-card-title\">\u598a\u5a20\u304b\u3089\u51fa\u7523\u307e\u3067\u80ce\u5150\u306e\u6210\u9577\u904e\u7a0b\u3068NIPT(\u65b0\u578b\u51fa\u751f\u524d\u8a3a\u65ad)\u306b\u3064\u3044\u3066\u3010\u533b\u5e2b\u76e3\u4fee\u3011 <\/div>\n          <div class=\"blog-card-excerpt\">\u598a\u5a20\u3057\u3066\u304b\u3089\u51fa\u7523\u307e\u3067\u80ce\u5150\u306e\u8eab\u4f53\u306f\u65e5\u3005\u5909\u5316\u3057\u3066\u3044\u304d\u307e\u3059\u3002\u307b\u3093\u306e1mm\u306b\u3082\u6e80\u305f\u306a\u304b\u3063\u305f\u53d7\u7cbe\u5375\u304c\u3001\u7d043000g\u306e\u8d64\u3061\u3083\u3093\u306b\u6210\u9577\u3059\u308b\u307e\u3067\u306e\u598a\u5a20\u9031\u6570\u3068...<\/div>\n      <\/div>\n    <\/a>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"c6\"><span class=\"ez-toc-section\" id=\"If_you_have_any_concerns_about_your_medicines_consult_your_doctor_or_pharmacist\"><\/span>If you have any concerns about your medicines, consult your doctor or pharmacist<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Medication can be a reliable way to improve physical and mental health issues, but it can be hard to know how to use it during pregnancy.
