This medicine contains <strong>mefenamic acid 500 mg<\/strong> and is used for the <strong>relief of period pain<\/strong>. It is an <strong>S2 medicine<\/strong>, which means it can be obtained without a doctor\u2019s prescription, but that does not mean it is suitable for everyone or that it can be used casually.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What it is and what it is used for<\/h2>\n\n\n\n<h3 class=\"wp-block-heading has-medium-font-size\">Active ingredient and medicine type<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">FENAMIN-500 contains <strong>mefenamic acid<\/strong> as its active ingredient. Each film-coated tablet contains <strong>500 mg<\/strong> of mefenamic acid.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It is described in the source as an <strong>antipyretic and anti-inflammatory analgesic<\/strong>. In everyday language, this means it is a medicine used to help with pain and inflammation.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What it is used for<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">According to the source, FENAMIN-500 is used for:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Relief of period pain<\/strong><\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">No other approved uses are specified in the source.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How it works (simple explanation)<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">If you are taking FENAMIN-500 for period pain, the idea is that it helps reduce the pain and inflammation linked to your menstrual cramps. In simple terms, it is meant to help your body feel less sore and uncomfortable during your period.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The source identifies it as an anti-inflammatory pain medicine, but it does not give a detailed scientific explanation of how mefenamic acid works in the body. So, beyond that basic description, the exact mechanism is <strong>not specified in the source<\/strong>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Who should NOT use this medicine<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Do <strong>not<\/strong> use FENAMIN-500 if you:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>are allergic to <strong>mefenamic acid<\/strong><\/li>\n\n\n\n<li>are allergic to <strong>any ingredient<\/strong> in FENAMIN-500<\/li>\n\n\n\n<li>have ever had an allergic reaction to <strong>aspirin<\/strong> or other related painkillers<\/li>\n\n\n\n<li>have or have ever had a <strong>stomach ulcer<\/strong><\/li>\n\n\n\n<li>have had a <strong>perforation<\/strong> or <strong>bleeding caused by NSAIDs<\/strong><\/li>\n\n\n\n<li>have <strong>inflammatory bowel disease<\/strong>, including:<\/li>\n\n\n\n<li><strong>ulcerative colitis<\/strong><\/li>\n\n\n\n<li><strong>Crohn\u2019s disease<\/strong><\/li>\n\n\n\n<li>have <strong>epilepsy<\/strong><\/li>\n\n\n\n<li>have a <strong>liver problem<\/strong><\/li>\n\n\n\n<li>have a <strong>kidney problem<\/strong><\/li>\n\n\n\n<li>have <strong>heart problems<\/strong><\/li>\n\n\n\n<li>are <strong>20 weeks pregnant or later<\/strong>, unless a healthcare professional has specifically advised you to use an NSAID<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Important pregnancy-related restriction<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Do not use this medicine during pregnancy at <strong>20 weeks or later<\/strong> unless a healthcare professional has specifically told you to do so. The source warns that NSAIDs may cause problems in the unborn baby. It also states that you should <strong>not take NSAIDs around 30 weeks of pregnancy or later<\/strong>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Warnings and precautions (Read before use)<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Even though FENAMIN-500 can be bought without a prescription, there are important situations where you need to be extra careful. Before taking it, think about your health conditions, the medicines you already use, and whether any of the warnings apply to you.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Be careful if you have any of the following<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Speak to a healthcare professional before using FENAMIN-500 if you:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>have <strong>asthma<\/strong><\/li>\n\n\n\n<li>have <strong>bowel problems<\/strong><\/li>\n\n\n\n<li>are prone to <strong>allergic reactions<\/strong>, such as <strong>hay fever<\/strong><\/li>\n\n\n\n<li>have <strong>heart problems<\/strong><\/li>\n\n\n\n<li>have had a <strong>stroke before<\/strong><\/li>\n\n\n\n<li>think you may be at risk of heart disease or stroke, for example if you:<\/li>\n\n\n\n<li>have <strong>high blood pressure<\/strong><\/li>\n\n\n\n<li>have <strong>diabetes<\/strong><\/li>\n\n\n\n<li>have <strong>high cholesterol<\/strong><\/li>\n\n\n\n<li><strong>smoke<\/strong><\/li>\n\n\n\n<li>are <strong>elderly<\/strong><\/li>\n\n\n\n<li>have a <strong>bleeding disorder<\/strong><\/li>\n\n\n\n<li>are <strong>dehydrated<\/strong><\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Extra caution for older adults<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">If you are older, you need to be especially careful. The source says older people have a higher chance of side effects with NSAIDs such as FENAMIN-500, especially <strong>gastrointestinal bleeding<\/strong> and <strong>perforation<\/strong>. These problems can be very serious and may be fatal.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Serious skin or immune reactions<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Get medical help if you develop:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>a <strong>fever<\/strong><\/li>\n\n\n\n<li>a <strong>skin rash<\/strong><\/li>\n\n\n\n<li><strong>swollen lymph nodes<\/strong><\/li>\n\n\n\n<li><strong>swelling of the face<\/strong><\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The source says this may be a serious reaction known as <strong>DRESS<\/strong> (Drug Reaction with Eosinophilia and Systemic Symptoms).<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Heart and circulation warning<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The source states that medicines such as FENAMIN-500 have been linked to a <strong>small increased risk of heart attack or stroke<\/strong>. This matters even more if you already have heart-related risk factors or circulation problems.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Driving and using machinery<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">FENAMIN-500 may make you feel:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>dizzy<\/strong><\/li>\n\n\n\n<li><strong>drowsy<\/strong><\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">If this happens, do not drive, use machinery, or do anything that requires you to stay alert.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Sugar and lactose warning<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">FENAMIN-500 contains <strong>lactose monohydrate 143 mg<\/strong>. If you have <strong>diabetes mellitus<\/strong>, the source says this may affect your blood sugar control. You should also avoid this medicine if you have the rare hereditary conditions of <strong>lactose intolerance<\/strong> or <strong>galactose intolerance<\/strong>.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\"><strong>Warning:<\/strong> If you are not sure whether lactose or sugar in medicines affects you, ask your pharmacist or doctor before using FENAMIN-500.<\/p>\n<\/blockquote>\n\n\n\n<h2 class=\"wp-block-heading\">Pregnancy, planning pregnancy, and breastfeeding<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">If you are pregnant, think you may be pregnant, are planning to become pregnant, or are breastfeeding, you should speak to your <strong>doctor, pharmacist, or another healthcare provider<\/strong> before taking FENAMIN-500.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Pregnancy<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The source gives specific caution for pregnancy:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>NSAIDs should <strong>not<\/strong> be used at <strong>20 weeks of pregnancy or later<\/strong> unless a healthcare professional specifically advises it.<\/li>\n\n\n\n<li>Taking NSAIDs at around <strong>20 weeks or later<\/strong> may harm the unborn baby.<\/li>\n\n\n\n<li>If an NSAID is needed for <strong>more than 2 days<\/strong> between <strong>20 and 30 weeks of pregnancy<\/strong>, a healthcare provider may need to monitor the amount of fluid in the womb around the baby.<\/li>\n\n\n\n<li>You should <strong>not take NSAIDs around 30 weeks of pregnancy or later<\/strong>.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Planning pregnancy<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">If you are planning a pregnancy, the source advises you to tell your doctor or healthcare provider before using the medicine.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Breastfeeding<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The source says you should ask your healthcare provider for advice before taking FENAMIN-500 if you are breastfeeding.
