Is Bentyl a narcotic? 

No, Bentyl (Dicyclomine) is not a narcotic or a controlled substance. This is an anticholinergic medication which is generally prescribed for the management and treatment of Irritable Bowel Syndrome (IBS). 

Bentyl doesn’t affect your psychological functions if you stick to the dosage strength and frequency prescribed by your doctor, and it doesn’t get you high. 

However, taking a high amount of this medication can cause some psychological side effects. Another reason why Bentyl should not be overused, especially in the summer season, is that it reduces your ability to sweat – as it is an anticholinergic medication. 

This can significantly increase your body temperature as your body fails to release the excess heat via sweat. Make sure you take this medication properly. If you’re concerned about any side effects, reach out to your healthcare provider. 

How is Bentyl different from narcotics?

Bentyl is entirely different from narcotics. It belongs to a class of drugs called antispasmodics, which work by relaxing the muscles in the digestive tract (1). On the other hand, narcotic drugs are a class of pain medications that act on the central nervous system to relieve pain.

The main difference between Bentyl and narcotic drugs is their mechanism of action and primary use. Bentyl is specifically designed to target and relieve symptoms related to IBS, such as abdominal pain, cramping, and bloating (2). It helps to relax the muscles in the intestines, reducing spasms and discomfort.

Narcotic drugs, on the other hand, are primarily used for managing moderate to severe pain. They work by binding to opioid receptors in the brain and spinal cord, altering the perception of pain. (3,4)

In terms of side effects, Bentyl may cause common side effects such as dry mouth, dizziness, blurred vision, and constipation, and it may rarely cause weight changes. These side effects are typically mild and temporary.

Narcotic drugs, however, have a different side effect profile. They can cause more potent effects on the central nervous system, including drowsiness, sedation, confusion, and respiratory depression. Long-term use of narcotic drugs can also lead to physical dependence and addiction.

Final words

To sum up, Bentyl is not a narcotic and it doesn’t act like one. However, it can cause side effects. It’s important to note that the side effects and risks associated with medication can vary depending on the individual and the specific drug. 

It is always recommended to consult with a healthcare professional for safe and effective use of medications.
