What is Hyoscyamine?
Hyoscyamine (pronounced hye-oh-sye-a-meen) is an antispasmodic medication that helps treat symptoms of irritable bowel syndrome (IBS). IBS is a long-term condition that affects the gut. While it isn’t a serious condition, it can cause unpleasant symptoms such as bloating, flatulence, constipation, and diarrhea.
These symptoms are typically short-lived, but when they persist, they can have a significant impact on day-to-day life. Hyoscyamine can help relax the stomach, which helps relieve some of these symptoms.
Hyosciamine hasn’t been approved by the FDA for IBS, but it’s commonly prescribed for this condition off-label (simply meaning that it’s prescribed in a different way or for a different condition than what’s specified in the medication guide).
How does Hyoscyamine work?
Hyoscyamine is an antispasmodic and anticholinergic medicine. It works by blocking the action of acetylcholine in the gastrointestinal tract. This prevents muscles from spasming and contracting, which helps alleviate symptoms such as cramping and flatulence.[1] It essentially relaxes the stomach and intestines, which helps to reduce and relieve symptoms.
Is there a branded version of Hyoscyamine?
Yes, there are branded versions of Hyoscyamine that are available under different names, such as Levsin and Hyosyne. There aren’t many differences between the generic and branded versions insofar as how the medicine works. According to the FDA, generic treatments work as well as the branded versions.[2] The main difference is the price, with generic options usually being cheaper.
Does Hyoscyamine cause weight loss?
Weight loss isn’t listed as a side effect for Hyoscyamine, but some people may experience some weight changes with IBS.
IBS can cause nausea, diarrhea, and constipation. When these effects occur long-term, it can affect someone’s diet and potentially lead to weight fluctuations, and negatively impact mental well-being and self-esteem in severe cases.
Whether you’re using treatment or not, if you lose a lot of weight unexpectedly, contact your doctor straight away.
What doses of Hyoscyamine are there?
Hyoscyamine comes as a 0.125mg dose. The typical dose is 1 to 2 tablets up to four times a day. This can be increased to every four hours if the symptoms are worse. But you should never take more than 12 tablets in 24 hours.
