In a normal state, urine flows freely from the bladder through the urethra. When the prostate gland enlarges, it can compress against the urethra and weaken urinary flow. Terazosin helps reduce the compression.&nbsp;<\/p>\n\n\n\n<p>To treat hypertension (high blood pressure), terazosin blocks signals from alpha-1 receptors telling blood vessels to constrict. Blood vessels widen, reducing resistance and allowing blood to flow freely which helps lower blood pressure.<\/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>Hytrin, Tezruly<\/td>\n      <\/tr>\n\n      <tr>\n         <td><strong>Drug Class<\/strong><\/td>\n        <td>Selective alpha-1 adrenergic receptor antagonist (alpha-1 blocker)<\/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>Many patients begin taking terazosin capsules at a lower dose, which is gradually titrated (increased) over time based on their response to the medication. The slow progression allows the patient&#8217;s body to adapt and reduces the risk of side effects.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Initial dose: <\/strong>Standard guidelines suggest a starting dose of 1 mg per day, taken at bedtime. The timing of this first dose is considered critical for patient safety due to the risk of low blood pressure and falls when initiating therapy.<\/li>\n\n\n\n<li><strong>BPH maintenance: <\/strong>To manage prostate-related symptoms, providers generally titrate patients up to 2, 5, or 10 mg per day. It can take up to 6 weeks before patients notice improvements to their urinary flow.<\/li>\n\n\n\n<li><strong>Hypertension maintenance: <\/strong>The typical range for hypertension maintenance is 1 to 5 mg of terazosin per day. Some patients may require higher doses.<\/li>\n<\/ul>\n\n\n\n<p><em><strong>Note:<\/strong> Dosing information below is educational only.

Serious side effects from taking terazosin can include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Fainting: <\/strong>Terazosin can cause a sudden drop in blood pressure that can lead to fainting and loss of consciousness. This is especially common after the first dose or a dosage increase.<\/li>\n\n\n\n<li><strong>Priapism: <\/strong>In rare cases, terazosin can lead to a painful erection that lasts more than 4 hours. This is considered a medical emergency and, if not treated, can lead to permanent tissue damage.<\/li>\n\n\n\n<li><strong>Intraoperative floppy iris syndrome: <\/strong>This condition can occur during cataract or glaucoma surgery. Patients who are planning eye surgery should speak to their doctor if they are taking terazosin or another alpha-blocker.<\/li>\n\n\n\n<li><strong>Tachycardia: <\/strong>Terazosin may lead to an increased heart rate, sometimes felt as a racing or pounding heartbeat.<\/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-don-t-stop-and-restart-without-doctor-approval\">Don&#8217;t Stop and Restart Without Doctor Approval<\/h3>\n\n\n\n<p>If a patient stops taking terazosin for several days, standard guidelines caution they should not take their previous dose after resuming their treatment. Instead, they are advised to contact their provider, who may recommend restarting the medication at the initial 1 mg dose.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-follow-first-dose-protocols\">Follow First Dose Protocols<\/h3>\n\n\n\n<p>Per standard guidelines, patients are advised to take their first dose before bed to ensure personal safety if a sudden drop in blood pressure occurs. The same suggestion applies to taking the capsule after subsequent dosage increases.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-get-up-slowly\">Get Up Slowly<\/h3>\n\n\n\n<p>Terazosin can cause a drop in blood pressure, which can make you feel lightheaded if you stand up quickly. This increases your risk of fainting and injury from a fall. Getting up slowly can mitigate these risks.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-be-careful-with-alcohol\">Be Careful With Alcohol<\/h3>\n\n\n\n<p>Alcohol can enhance the effects of terazosin, leading to a sudden drop in blood pressure and increasing your risk of fainting. Limited alcohol intake is recommended when taking terazosin, especially when first starting the medication.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-consistency-is-key\">Consistency Is Key<\/h3>\n\n\n\n<p>Terazosin can be taken with or without food, according to clinical guidelines, but taking the capsule at the same time every night helps ensure a steady level of medication in your body during the 24-hour cycle.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-drug-interactions\">Drug Interactions<\/h2>\n\n\n\n<p>Terazosin can interact with other medications and substances that affect blood pressure or muscle relaxation. Known interactions with terazosin include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Erectile dysfunction (ED) medications: <\/strong>PDE-5 inhibitors such as sildenafil (Viagra) and tadalafil (Cialis) are vasodilators. When taken with terazosin, they may cause additive hypotension and increase the risk of adverse effects.<\/li>\n\n\n\n<li><strong>Other antihypertensive medications: <\/strong>Taking terazosin alongside other hypertension medications such as beta-blockers, ACE inhibitors, and diuretics can cause blood pressure to drop too low. Careful medical monitoring is recommended in these instances.<\/li>\n\n\n\n<li><strong>Nonsteroidal anti-inflammatory drugs (NSAIDs) and cold medicines: <\/strong>Some over-the-counter NSAIDs and cold medicines contain decongestants that raise blood pressure. Taking these medications can counteract the effects of terazosin.<\/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 should I take my first dose right before I get into bed?<\/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>The first dose of terazosin can cause a significant drop in blood pressure.
