Hyoscyamine (HYE oh SYE a meen) is a generic medication prescribed for certain conditions affecting the gastrointestinal (GI) system. It’s also prescribed for other conditions. Hyoscyamine belongs to a group of drugs called anticholinergics.
Doctors may prescribe hyoscyamine to treat or manage the symptoms of:
- certain conditions affecting the GI system, such as irritable bowel syndrome (IBS)
- certain bladder or kidney problems
- parkinsonism (movement disorders, such as Parkinson’s disease)
- rhinitis (runny nose)
Doctors may also prescribe hyoscyamine to aid in anesthesia during surgery.
These uses may differ based on the form of hyoscyamine your doctor prescribes.
Note: The Food and Drug Administration (FDA) has not approved hyoscyamine. This is because the drug has been available since before the FDA began its drug approval process. If you have questions about this, talk with your doctor or pharmacist.
This article doesn’t provide coupons for all forms of hyoscyamine. To find coupons for hyoscyamine’s other forms, see these articles:
FAQs
Common questions about hyoscyamine
Below you’ll find answers to a few commonly asked questions about hyoscyamine.
Is hyoscyamine a ‘narcotic’?
No, hyoscyamine isn’t a narcotic. Narcotics are drugs that are similar to opium. They provide pain relief but are highly addictive. Examples of narcotics include morphine and hydromorphone.
Narcotics are sometimes used in anesthesia during surgery to assist with pain management. In some cases, doctors prescribe hyoscyamine as part of anesthesia during surgery. But hyoscyamine isn’t a narcotic or a controlled substance. (A controlled substance is a drug the government regulates due to the risk of dependence or misuse.)
In addition, doctors may prescribe hyoscyamine along with morphine or other narcotics to relieve pain caused by biliary and renal colic. (“Biliary and renal colic” refers to a type of pain caused by gallstones, kidney stones, or something else causing a blockage in the gallbladder or kidneys.)
If you have questions about hyoscyamine or narcotics, talk with your doctor or pharmacist.
What brand names are available for hyoscyamine?
Hyoscyamine is a generic drug. Brand-name drugs that contain hyoscyamine include:
- Anaspaz
- Hyosyne
- Levbid
- Levsin
- Levsin SL
- NuLev
- Oscimin
A generic medication is an identical copy of the active drug in a brand-name medication. (An active drug is the ingredient that makes a drug work.) Generic drugs are believed to be as effective and safe as brand-name drugs. And generic drugs typically cost less compared to brand-name drugs.
Talk with your doctor or pharmacist if you have questions about how hyoscyamine compares to brand-name drugs.
Is hyoscyamine available over the counter?
No, hyoscyamine isn’t available over the counter. Hyoscyamine is a prescription drug.
In some cases, over-the-counter (OTC) medications can be used to relieve some symptoms of the conditions that hyoscyamine is prescribed to treat.
For example, doctors may prescribe hyoscyamine to manage irritable bowel syndrome (IBS). IBS can cause diarrhea or constipation. In some cases, doctors may recommend OTC anti-diarrheal medications or laxatives to manage IBS symptoms.
If you have questions about hyoscyamine or OTC medications, talk with your doctor or pharmacist.
How does hyoscyamine work? And how long does it take to start working?
Hyoscyamine works by blocking the actions of acetylcholine. Acetylcholine is a chemical messenger involved in muscle contraction among other body functions. When hyoscyamine blocks acetylcholine, the drug helps stop muscle contractions or spasms.
Acetylcholine also plays a role in producing various body fluids, such as saliva and stomach acid. By blocking acetylcholine, hyoscyamine works to reduce the production of these body fluids.
Hyoscyamine comes in immediate- and extended-release forms. The immediate-release form begins working right away, while the extended-release form requires a few hours to start working.
If you’d like to know more about this, talk with your doctor or pharmacist.
Uses
Uses of hyoscyamine
The Food and Drug Administration (FDA) approves prescription drugs for certain conditions. Common uses for hyoscyamine are described below. These uses may differ based on the form of hyoscyamine your doctor prescribes.
Hyoscyamine is a prescription drug, but the FDA has not approved it. This is because the drug has been available since before the FDA began its drug approval process. If you have questions about this, talk with your doctor or pharmacist.
Use for certain gastrointestinal conditions
Doctors may prescribe hyoscyamine for treating certain conditions affecting the gastrointestinal (GI) system. It’s used for this purpose in adults and some children. It’s prescribed as a short- or long-term treatment, depending on the GI condition.
Examples of GI conditions that doctors may prescribe oral forms of hyoscyamine to treat include:
- irritable bowel syndrome (IBS)
- neurogenic bowel, which occurs when nerve damage causes problems with bowel movements
- peptic ulcer disease (sores in the GI tract due to excess stomach acid)
- GI disorders that involve inflammation of the intestines, such as dysentery, diverticulitis, and enterocolitis
- management of stomach acid production
- management of abdominal cramps or GI spasms
In addition, doctors may prescribe and administer hyoscyamine injection to:
- reduce movement of the GI tract during diagnostic tests or procedures*
- reduce symptoms of pancreatitis (inflammation of the pancreas, an organ involved in digestion)*
Symptoms of GI conditions vary with the specific condition, but may include diarrhea, constipation, or abdominal pain.
Doctors may prescribe other medications for these uses in addition to hyoscyamine.
* For this use, doctors may prescribe and administer the injection form of hyoscyamine.
Use for certain bladder or kidney problems
Doctors may prescribe hyoscyamine for treating certain bladder or kidney problems. It’s used for this purpose in adults and some children. It’s usually prescribed as a short-term treatment.
Doctors may prescribe oral forms of hyoscyamine or hyoscyamine injection for the following uses related to the bladder or kidneys:
- to reduce muscle spasms of the bladder
- to reduce symptoms of cystitis (bladder infection causing inflammation), such as frequent urge to urinate or feeling as if your bladder is full after you’ve emptied your bladder
- neurogenic bladder, which occurs when nerve damage causes problems controlling the bladder
- to improve visibility of the kidneys for certain radiology imaging tests
- to relieve symptoms of biliary and renal colic (“Biliary and renal colic” refers to a type of pain caused by gallstones, kidney stones, or something else blocking the usual flow of fluids from gallbladder or kidneys.)
Doctors may prescribe other medications for these uses along with hyoscyamine. Hyoscyamine is prescribed together with morphine or other pain medications for relieving symptoms of biliary and renal colic.
Use for managing certain symptoms of parkinsonism
Doctors may prescribe hyoscyamine for managing certain symptoms of parkinsonism (movement disorders, such as Parkinson’s disease). It’s used for this purpose in adults. It’s usually prescribed as a long-term treatment.
With parkinsonism, you have problems with your nerves and movements. Hyoscyamine may be prescribed to reduce the following symptoms of parkinsonism:
- muscle rigidity
- tremors
- drooling
- excess sweating
Doctors may prescribe other medications for this purpose along with hyoscyamine.
Use for runny nose
Doctors may prescribe hyoscyamine tablets, elixir, solution, dissolving tablets, or extended-release tablets for treating symptoms of rhinitis (runny nose). It’s used for this purpose in adults and children. It’s usually prescribed as a short-term treatment.
With a runny nose, the nasal passages become inflamed due to allergies, irritation, or an infection. You may have mucus dripping from your nostrils or down the back of your throat.
Use to aid in anesthesia
Doctors may prescribe hyoscyamine injection to aid in anesthesia. It’s used for this purpose in adults and children ages 2 years and older. It’s usually prescribed as a short-term treatment.
Anesthesia is given to cause a temporary state of sleep, numbness, and stillness during surgery. To help you breathe during anesthesia, doctors place a breathing tube in your airway (intubation). However, the body tries to fight against the breathing tube by producing excess saliva and activating certain reflexes.
Hyoscyamine may be given along with anesthesia drugs to reduce saliva production and block these reflexes. This allows for smoother intubation and anesthesia procedures.
