Hyoscyamine also works on the central nervous system and specific glands to decrease the production of various bodily fluids, including sweat, saliva, and stomach acid. It belongs to a group of medications known as anticholinergics or antispasmodics.<\/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>Anaspaz, Cystospaz, NuLev, Levbid, Levsin, Symax, Hyosyne, Oscimin<\/td>\n      <\/tr>\n\n      <tr>\n         <td><strong>Drug Class<\/strong><\/td>\n        <td>Anticholinergic, antispasmodic<\/td>\n      <\/tr>\n\n      <tr>\n        <td><strong>Generic Status<\/strong><\/td>\n        <td>Generic is 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>The dosage of hyoscyamine can depend on the specific form you\u2019re taking and what you\u2019re taking it to treat. It is available as immediate-release tablets, extended-release tablets, sublingual tablets, orally disintegrating tablets (ODT), and liquid solutions like elixirs or drops.<\/p>\n\n\n\n<p>Your provider will tell you how to take hyoscyamine. Here are some typical dosing regimens for adults:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Immediate-release tablets: <\/strong>The recommended dose is 1 to 2 tablets by mouth every 4 hours or as needed.

Stop using hyoscyamine and call your doctor immediately if you experience:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Severe allergic reactions:<\/strong> Symptoms include swelling of the face, lips, tongue, or throat; difficulty breathing or swallowing; racing heart; severe rash or itching; fever.\u00a0<\/li>\n\n\n\n<li><strong>Heat exhaustion or heatstroke:<\/strong> Because hyoscyamine decreases sweating, it may make it tougher to control your body temperature. This can increase your risk of overheating in hot weather. Symptoms include increased body temperature, decreased sweating, dizziness, tiredness, and nausea.<\/li>\n\n\n\n<li><strong>Reduced alertness or coordination:<\/strong> Hyoscyamine\u2019s effects on your nervous system may affect your alertness or coordination. It\u2019s recommended to avoid driving or operating heavy machinery until you know how the medication affects you.<\/li>\n\n\n\n<li><strong>Psychosis or hallucinations:<\/strong> Hyoscyamine can cause psychotic-like behavior, such as seeing or hearing things that aren\u2019t there (hallucinations). Other symptoms include confusion, delusional or disorganized thoughts, agitation or aggressive behavior, memory loss, and a sudden decline in personal hygiene or performance at work or school.<\/li>\n\n\n\n<li><strong>Bowel blockage:<\/strong> Hyoscyamine may cause a bowel blockage. Symptoms include severe stomach cramps, inability to have a bowel movement or pass gas, loss of appetite, and vomiting.<\/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-take-with-or-without-food\">Take With or Without Food<\/h3>\n\n\n\n<p>You can take hyoscyamine with or without food. If it upsets your stomach, taking it with food may offer relief.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-let-odt-and-sublingual-tablets-dissolve-before-swallowing\">Let ODT and Sublingual Tablets Dissolve Before Swallowing<\/h3>\n\n\n\n<p>Sublingual tablets should be placed under the tongue, while orally disintegrating tablets should be placed on top of the tongue. Allow the tablet to dissolve completely. Do not swallow it whole, and avoid eating, drinking, or smoking while it is dissolving.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-swallow-extended-release-tablets-whole\">Swallow Extended-Release Tablets Whole<\/h3>\n\n\n\n<p>Do not chew, split, or crush them, as this can affect how the medication is absorbed. It is normal to occasionally see parts of the tablet in your stool.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-stay-hydrated\">Stay Hydrated<\/h3>\n\n\n\n<p>Because hyoscyamine reduces saliva and sweat, you may be more likely to overheat and experience dry mouth or thirstiness. Stay hydrated by drinking plenty of water. Avoid prolonged exposure to hot weather to prevent heatstroke.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-wait-to-see-how-the-medication-affects-you\">Wait To See How The Medication Affects You<\/h3>\n\n\n\n<p>Hyoscyamine can impair your coordination and focus. Avoid driving, operating heavy machinery, or performing tasks that require your full alertness until you understand how the medication affects you.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-store-at-room-temperature\">Store At Room Temperature<\/h3>\n\n\n\n<p>Hyoscyamine should be stored at 68\u00b0F to 77\u00b0F (20\u00b0C to 25\u00b0C) in a cool, dry place.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-consider-limiting-alcohol\">Consider Limiting Alcohol<\/h3>\n\n\n\n<p>Drinking alcohol while taking hyoscyamine may increase your risk of dizziness or drowsiness on the medication.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-tell-your-provider-if-you-re-pregnant-or-breastfeeding\">Tell Your Provider If You\u2019re Pregnant Or Breastfeeding<\/h3>\n\n\n\n<p>It is not known if hyoscyamine can affect pregnancy or harm an unborn baby, but it does pass into breast milk. Tell your healthcare provider if you are pregnant, breastfeeding, or planning to be, so they can advise whether this medication is safe for you to take.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-try-to-avoid-missing-a-dose\">Try To Avoid Missing A Dose<\/h3>\n\n\n\n<p>If you miss a dose of hyoscyamine, take it as soon as you remember, unless it is almost time for your next dose. In that case, skip the missed dose and take your next dose as scheduled. Do not take double or extra doses to make up for a missed one.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-drug-interactions\">Drug Interactions<\/h2>\n\n\n\n<p>Certain medications and substances can interact with hyoscyamine, potentially altering how it works or increasing the risk of side effects. For example:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Antacids:<\/strong> Over-the-counter antacids containing calcium, aluminum, or magnesium can affect how well hyoscyamine is absorbed.
