When you\u2019re taking warfarin, you\u2019ll need your INR tested regularly, as well as your prothrombin time.&nbsp;<\/p>\n\n\n\n<p>The INR (international normalized ratio) is calculated using the prothrombin time and measures how long it takes your blood to clot.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-what-are-the-side-effects-of-warfarin\">What are the side effects of warfarin?<\/h2>\n\n\n\n<p>Some of the potential side effects of taking warfarin may include (italics = most common):<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><em>Increased bleeding<\/em><\/li>\n\n\n\n<li><em>Increased bruising<\/em><\/li>\n\n\n\n<li>Gas<\/li>\n\n\n\n<li>Abdominal pain<\/li>\n\n\n\n<li>Bloating<\/li>\n\n\n\n<li>Change in the way things taste<\/li>\n\n\n\n<li>Loss of hair<\/li>\n\n\n\n<li>Feeling cold or having chills<\/li>\n<\/ul>\n\n\n\n<p>While it\u2019s rarer, warfarin comes with a black box warning from the FDA due to its ability to cause severe bleeding.&nbsp;<\/p>\n\n\n\n<p>If you experience any of these signs of abnormal bleeding or wounds while taking warfarin, reach out to your healthcare provider.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Bloody, red, or tarry bowel movements (a sign of a bowel bleed)<\/li>\n\n\n\n<li>Spitting or coughing up blood<\/li>\n\n\n\n<li>Heavy bleeding with your menstrual period<\/li>\n\n\n\n<li>Pink, red, or dark brown urine<\/li>\n\n\n\n<li>Coughing up or vomiting material that looks like coffee grounds<\/li>\n\n\n\n<li>Small, flat, round red spots under the skin<\/li>\n\n\n\n<li>Unusual bruising or bleeding<\/li>\n\n\n\n<li>Continued oozing or bleeding from minor cuts<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-which-drugs-can-warfarin-interact-with\">Which drugs can warfarin interact with?&nbsp;<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-aspirin-acetylsalicylic-acid\">Aspirin (acetylsalicylic acid)<\/h3>\n\n\n\n<p>Taking warfarin with aspirin can increase your bleeding risk since aspirin is also meant to <a href=\"https:\/\/blog.bensnaturalhealth.com\/general-health\/how-to-prevent-blood-clots\/\" target=\"_blank\" rel=\"noreferrer noopener\">prevent blood clots<\/a>.&nbsp;<\/p>\n\n\n\n<p>Some healthcare providers recommend taking low-dose aspirin to reduce the risk of heart attack and stroke in lower-risk patients.&nbsp;<\/p>\n\n\n\n<p>If you were already taking aspirin and are prescribed warfarin, you may need to discontinue aspirin based on the advice of your healthcare provider.&nbsp;<\/p>\n\n\n\n<p>Taking aspirin and warfarin together may also irritate the lining of your stomach and lead to stomach ulcers.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-other-medications\">Other medications<\/h3>\n\n\n\n<p>Some over-the-counter and prescription drugs might interact with warfarin, which can increase your risk of bleeding or reduce warfarin\u2019s effectiveness and increase your risk of forming a blood clot.<\/p>\n\n\n\n<p>Some of the medications that might interact with warfarin include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Acetaminophen (Tylenol, others) or acetaminophen-containing products<\/li>\n\n\n\n<li>Antacids or laxatives<\/li>\n\n\n\n<li>Certain antibiotics<\/li>\n\n\n\n<li>Antifungal medications, such as fluconazole (Diflucan)<\/li>\n\n\n\n<li>Cold or allergy medicines<\/li>\n\n\n\n<li>Ibuprofen (Advil, Motrin IB, etc.) or naproxen sodium (e.g. Aleve)<\/li>\n\n\n\n<li>Medications that treat irregular heart rhythms, such as amiodarone<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-other-blood-thinning-medications\">Other blood-thinning medications<\/h3>\n\n\n\n<p>You shouldn\u2019t take two anticoagulant medications at the same time because it can increase your risk of severe bleeding.&nbsp;<\/p>\n\n\n\n<p>Some prescription anticoagulants besides warfarin include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/blog.bensnaturalhealth.com\/general-health\/xarelto-vs-eliquis\/\" target=\"_blank\" rel=\"noreferrer noopener\">rivaroxaban (Xarelto)<\/a><\/li>\n\n\n\n<li>dabigatran (Pradaxa)<\/li>\n\n\n\n<li><a href=\"https:\/\/blog.bensnaturalhealth.com\/general-health\/eliquis-vs-warfarin\/\" target=\"_blank\" rel=\"noreferrer noopener\">apixaban (Eliquis)<\/a><\/li>\n\n\n\n<li>edoxaban (Lixiana)<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-certain-supplements\">Certain supplements<\/h3>\n\n\n\n<p>Some vitamins and supplements might interact with warfarin.
