Identifying the C31 Pill
When searching for information about a pill, identifying it by its imprint code is the most reliable method. The blue, round pill marked with the imprint "C31" is Dicyclomine Hydrochloride 20 mg. It is crucial not to confuse this with other pills that may have similar markings but different shapes or colors, as this could lead to serious health complications. For instance, an oval white pill marked 'C 31' is actually Erythromycin, an antibiotic. This article focuses exclusively on the blue, round C31 pill containing Dicyclomine.
What is Dicyclomine (the C31 Pill)?
Dicyclomine, also sold under the brand name Bentyl, is an antispasmodic medication used primarily to alleviate symptoms of functional bowel/irritable bowel syndrome (IBS). It works by targeting the smooth muscles of the gastrointestinal (GI) tract and reducing their involuntary contractions. This action helps to ease abdominal cramping and discomfort associated with IBS.
Mechanism of Action
Dicyclomine belongs to the class of drugs known as anticholinergics. It operates through a dual mechanism to relax the GI tract's smooth muscles:
- Anticholinergic effect: Dicyclomine blocks the action of acetylcholine, a neurotransmitter that signals muscles in the stomach and intestines to contract. By blocking these signals, the medication prevents the muscle spasms characteristic of IBS.
- Musculotropic effect: In addition to its anticholinergic action, dicyclomine has a direct, relaxing effect on the smooth muscle itself.
Clinical Uses of Dicyclomine
The primary and approved use for the C31 pill (Dicyclomine) is for the treatment of IBS. A patient may be prescribed this medication to help manage the following symptoms during a flare-up:
- Painful abdominal cramping
- Bloating
- Diarrhea associated with IBS
It is important to note that dicyclomine is not a cure for IBS but rather a treatment for its specific symptoms. It is often used on an as-needed basis for flare-ups, but some patients may take it regularly to help manage their condition.
Dosage and Administration
The correct dosage of the C31 pill is determined by a healthcare provider and can be adjusted based on the individual patient's needs and how they respond to the medication. The administration of this medication should always follow the prescriber's instructions. Depending on the patient's response and tolerability, the doctor may adjust the dose. If the medication is ineffective or if side effects become a limiting factor, the drug may be discontinued.
Important Considerations
- Consistency: A certain amount of dicyclomine needs to be in your system for it to work effectively, so it's important to take it as prescribed.
- Timing: The medication can be taken with or without food. If it causes an upset stomach, taking it with food may help.
- Missed Doses: If a dose is missed, patients should continue their normal schedule and not take a double dose unless directed by a healthcare professional.
- Injection: An injectable form of dicyclomine is also available for patients who are unable to take oral medication.

Contraindications and Warnings
Dicyclomine is not safe for everyone. It is contraindicated in several patient populations and conditions:
- Infants: Should not be given to infants under 6 months of age due to risk of serious respiratory symptoms.
- Nursing mothers: Dicyclomine is excreted in breast milk and can cause serious side effects in breast-fed infants, as well as decrease milk production.

Conclusion
The blue, round C31 pill is Dicyclomine Hydrochloride 20 mg, a prescription medication used to treat the symptoms of Irritable Bowel Syndrome, particularly abdominal cramping and spasms. As an anticholinergic and antispasmodic, it works by relaxing the smooth muscles of the gastrointestinal tract. While it can be an effective treatment for many, it is not without risks and is contraindicated in several conditions, including for infants and nursing mothers.
