By preventing formation of the enzyme, fosinopril ensures blood vessels remain in a wider, or dilated, state.&nbsp;<\/p>\n\n\n\n<p>As blood vessels relax, the heart does not need to work as hard to pump blood throughout the body. This reduction of the heart&#8217;s workload is especially vital to people with heart failure. By reducing systemic pressure, fosinopril can also protect the kidney&#8217;s filtering units.<\/p>\n\n\n\n<div class=\"quick-facts-card\">\n  <table class=\"quick-facts-table\">\n    <colgroup>\n      <col\/>\n      <col\/>\n    <\/colgroup>\n\n    <thead>\n      <tr>\n        <th colspan=\"2\">Quick Facts<\/th>\n      <\/tr>\n    <\/thead>\n\n    <tbody>\n      <tr>\n        <td><strong>Common Brands<\/strong><\/td>\n        <td>Monopril (discontinued)<\/td>\n      <\/tr>\n\n      <tr>\n         <td><strong>Drug Class<\/strong><\/td>\n        <td>Angiotensin-converting enzyme (ACE) inhibitor<\/td>\n      <\/tr>\n\n      <tr>\n        <td><strong>Generic Status<\/strong><\/td>\n        <td>Generic version available<\/td>\n      <\/tr>\n\n      <tr>\n         <td><strong>Availability<\/strong><\/td>\n        <td>Prescription only<\/td>\n    <\/tbody>\n  <\/table>\n<\/div>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-dosing\">Dosing<\/h2>\n\n\n\n<p>Dosing for fosinopril is usually individualized and based on the patient&#8217;s blood pressure baseline. Other dosage factors may include age and the presence of other medications.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>For hypertension: <\/strong>Standard guidelines for fosinopril include a suggested starting dose of 10 mg per day. Providers may recommend a dosage increase up to 20 mg or 40 mg per day based on how the patient&#8217;s blood pressure responds during the first few weeks.<\/li>\n\n\n\n<li><strong>For heart failure: <\/strong>Providers typically start heart failure patients at a dose of 10 mg per day. Initial dose may be lower to prevent a drop in blood pressure for people who also take water pill diuretics.\u00a0<\/li>\n\n\n\n<li><strong>Titration: <\/strong>The full therapeutic effect of a single fosinopril dose may not be visible for up to 6 hours after the patient has ingested the tablet, and consistent results may take several weeks. For this reason, doctors generally wait before titrating, or increasing, the dose during the early stages of treatment.\u00a0<\/li>\n<\/ul>\n\n\n\n<p><em><strong>Note:<\/strong> Dosing information below is educational only. Your prescribing physician will determine your specific dose based on your individual health needs.\u00a0Always follow your healthcare provider\u2019s instructions for exact dosing.<\/em><\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-uses\">Uses<\/h2>\n\n\n\n<p><strong>FDA-Approved Uses<\/strong><\/p>\n\n\n\n<p>Fosinopril tablets are FDA-approved to manage hypertension, either as standalone treatment or in combination with another type of blood pressure medication.

Serious side effects from taking fosinopril tablets can include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Angioedema: <\/strong>Fosinopril can lead to angioedema, a rare but life-threatening allergic reaction characterized by rapid swelling of the face, lips, tongue, and throat. This requires emergency medical intervention, as the swelling can cause airway obstruction.<\/li>\n\n\n\n<li><strong>Hyperkalemia: <\/strong>ACE inhibitors like fosinopril can cause the body to retain potassium, potentially leading to excessively high levels. Symptoms include muscle weakness, confusion, and an irregular heartbeat.<\/li>\n\n\n\n<li><strong>Kidney dysfunction: <\/strong>Fosinopril can help protect the kidneys, but the drug can also decrease kidney filtration and lead to renal dysfunction in people with certain heart conditions or severe dehydration.<\/li>\n\n\n\n<li><strong>Liver toxicity: <\/strong>In rare cases, taking fosinopril can lead to liver toxicity. Key signs include elevated liver enzymes and jaundice (yellowing) of the skin and eyes.<\/li>\n\n\n\n<li><strong>Neutropenia: <\/strong>Fosinopril has been linked to neutropenia, a rare drop in white blood cell count that can increase the patient&#8217;s risk of infection.<\/li>\n<\/ul>\n\n<\/div>\n\n\n\n<p class=\"has-muted-color has-text-color\" style=\"font-size:0.875rem\"><em>Call your doctor immediately if you experience any concerning or prolonged symptoms.<\/em><\/p>\n\n\t<\/div>\n<\/section>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-pharmacist-tips\">Pharmacist Tips<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-timing-is-key\">Timing Is Key<\/h3>\n\n\n\n<p>Standard guidelines recommend taking fosinopril at the same time every day. Many patients prefer taking their tablet in the morning, but your provider may suggest evening doses if you are prone to daytime dizziness.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-get-up-slowly\">Get Up Slowly<\/h3>\n\n\n\n<p>Since fosinopril can lead to a drop in blood pressure, getting out of bed quickly increases the risk of dizziness and injury from a fall. Rising slowly is recommended after waking up, and you may need to sit on the edge for a moment to let your blood pressure catch up.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-stay-hydrated\">Stay Hydrated<\/h3>\n\n\n\n<p>Dehydration can lead to a steep drop in blood pressure while you&#8217;re taking fosinopril. Adequate water intake is key, especially while exercising or during periods of hot weather.\u00a0<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-log-your-blood-pressure\">Log Your Blood Pressure<\/h3>\n\n\n\n<p>While taking fosinopril, home monitoring with a blood pressure log is recommended to ensure the current dose is optimized to your needs.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-avoid-salt-substitutes\">Avoid Salt Substitutes<\/h3>\n\n\n\n<p>Many salt substitutes replace sodium with potassium chloride. Since fosinopril increases potassium levels, consuming these salt substitutes while taking the drug can lead to hyperkalemia and dangerously high potassium levels.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-drug-interactions\">Drug Interactions<\/h2>\n\n\n\n<p>Fosinopril can interact with various medications and supplements, and these interactions can potentially alter its effectiveness and increase the risk of side effects. Known interactions with fosinopril include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Nonsteroidal anti-inflammatory drugs (NSAIDs): <\/strong>Pain relievers like ibuprofen or naproxen can affect fosinopril&#8217;s ability to lower blood pressure and increase the risk of kidney damage.<\/li>\n\n\n\n<li><strong>Potassium supplements: <\/strong>Fosinopril can cause the body to retain potassium, so taking the drug alongside potassium supplements requires close medical supervision to ensure the patient&#8217;s potassium levels are not excessively high.<\/li>\n\n\n\n<li><strong>Sacubitril: <\/strong>Sold under the brand name Entresto, this medication is primarily used to manage heart failure. Per standard guidelines, patients are advised to avoid taking sacubitril within 36 hours of fosinopril or another ACE inhibitor due to the elevated risk of severe angioedema.\u00a0<\/li>\n\n\n\n<li><strong>Antacids: <\/strong>Antacids that contain aluminum or magnesium can interfere with fosinopril&#8217;s absorption. Providers generally recommend spacing out antacids and fosinopril with a buffer of at least 2 hours.<\/li>\n<\/ul>\n\n\n\n<p>Always give your doctor and pharmacist a complete list of all your medications, vitamins, and supplements to check for potential interactions.<\/p>\n\n\n\n<section class=\"telyrx-faq-section\" data-toc-title=\"FAQs\">\n\t<h2 class=\"telyrx-faq-heading\">FAQs<\/h2>\n\t\t<div class=\"telyrx-faq-items\">\n\t\t\n\n<details class=\"telyrx-faq-item\">\n\t<summary class=\"telyrx-faq-question\">\n\t\t<span class=\"telyrx-faq-question-text\">Why do I have a constant cough since I started taking fosinopril?<\/span>\n\t\t<svg class=\"telyrx-faq-chevron\" width=\"20\" height=\"20\" viewBox=\"0 0 20 20\" fill=\"none\" aria-hidden=\"true\">\n\t\t\t<path d=\"M5 7.5L10 12.5L15 7.5\" stroke=\"currentColor\" stroke-width=\"2\" stroke-linecap=\"round\" stroke-linejoin=\"round\"\/>\n\t\t<\/svg>\n\t<\/summary>\n\t<div class=\"telyrx-faq-answer\">\n\t\t\n\n<p>Your constant cough after starting fosinopril is known as the &#8220;ACE cough,&#8221; and is a common side effect of ACE inhibitors.
