Dicyclomine: Uses, Dosage, and Side Effects for IBS Relief

Summary of Key Points

Dicyclomine is a prescription medication commonly used to treat various gastrointestinal conditions, such as irritable bowel syndrome (IBS) and abdominal cramps. This antispasmodic drug works by relaxing the muscles in the gastrointestinal tract, helping to alleviate pain and discomfort caused by spasms. It is available in several forms, including tablets, capsules, and injections. Always consult your healthcare provider before starting or adjusting your dosage. For tailored advice, you may also consider scheduling a telemedicine consultation with one of our providers.

Names of the Medication

US Brand Name: Bentyl (Dicyclomine)

The “generic name” refers to the standard, non-branded name of the medication, while the brand name is assigned by the manufacturer. In this case, Dicyclomine is the generic name, and Bentyl is the brand name. Both terms are often used interchangeably to describe the same medication.

Pharmacologic Category

Dicyclomine belongs to the anticholinergic/antispasmodic class of medications. These drugs are specifically designed to reduce muscle spasms in the gastrointestinal tract, providing relief from symptoms such as abdominal pain and cramping.

Other medications in this category include hyoscyamine and scopolamine, which are also used to manage gastrointestinal spasms and related conditions.

Dicyclomine Dosage

Dicyclomine is prescribed to treat a variety of gastrointestinal conditions in adults. The dosage may vary depending on the specific condition being addressed. Always follow your healthcare provider’s instructions and consult them before making any changes to your dosage. For additional support, you can schedule a telemedicine appointment with one of our providers.

Contraindications for Dicyclomine Use

Contraindications refer to specific conditions or circumstances where a medication should not be used due to potential risks. Before starting Dicyclomine, it’s essential to be aware of the following contraindications:

1. Obstructive uropathy (urinary tract blockage): Dicyclomine can worsen urinary retention, making it unsuitable for individuals with urinary tract blockages.
2. Obstructive gastrointestinal diseases: Conditions such as bowel obstruction or severe constipation may be aggravated by Dicyclomine, as it slows intestinal movement.
3. Severe ulcerative colitis: By reducing gut motility, Dicyclomine may increase the risk of toxic megacolon, a serious complication of this condition.
4. Myasthenia gravis: This medication can exacerbate muscle weakness in individuals with this neuromuscular disorder.
5. Glaucoma: Dicyclomine may elevate intraocular pressure, potentially worsening symptoms in individuals with glaucoma.
6. Infants under 6 months: Serious side effects, including breathing difficulties, have been reported in infants taking Dicyclomine, making it unsafe for this age group.
7. Breastfeeding: Dicyclomine can pass into breast milk and may harm a nursing infant (further details are provided below).

Drug-to-Drug Interactions with Dicyclomine

Dicyclomine may interact with other medications, potentially increasing the risk of side effects or reducing the effectiveness of one or both drugs. It’s crucial to inform your healthcare provider about all medications, supplements, or herbal products you are currently taking. Some common interactions include:

1. Antihistamines: Medications like diphenhydramine (Benadryl) may intensify side effects such as drowsiness and dry mouth when taken with Dicyclomine.
2. Antidepressants: Tricyclic antidepressants, such as amitriptyline (Elavil), can amplify side effects like dry mouth, blurred vision, and constipation.
3. Antipsychotic medications: Drugs such as chlorpromazine (Thorazine) or clozapine (Clozaril) may increase the risk of overheating and confusion when combined with Dicyclomine.
4. Opioid pain medications: Medications like oxycodone (OxyContin) or hydrocodone (Vicodin) may heighten the likelihood of constipation and urinary retention.
5. Medications for Parkinson’s disease: Drugs such as benztropine (Cogentin) may exacerbate side effects like confusion and dry mouth when used alongside Dicyclomine.

Is Dicyclomine Safe During Pregnancy?

Is it safe to take Dicyclomine while pregnant?

The FDA classifies Dicyclomine as a Category B medication for pregnancy. This means that animal studies have not shown harm to the fetus, but there are no well-controlled studies in pregnant women. While Dicyclomine may be safe for some individuals, it’s essential to consult your healthcare provider to determine whether it is the right choice for you. If you are pregnant or planning to become pregnant, a telemedicine consultation can help you explore the safest and most effective treatment options for your condition.

Dicyclomine While Breastfeeding

Is it Safe to Take Dicyclomine While Breastfeeding?

Dicyclomine is generally not recommended for breastfeeding mothers. This antispasmodic medication can pass into breast milk and may cause serious side effects in nursing infants, including breathing difficulties, excessive drowsiness, and feeding problems. If you are breastfeeding, it is important to consult your healthcare provider to explore safer alternatives for managing your condition. Our telemedicine providers are available to help you find treatment options that prioritize both your health and your baby’s well-being.

Estimated Cost of Dicyclomine

The cost of a 30-day supply of Dicyclomine (20 mg tablets) without insurance typically ranges from $10 to $15 when using a GoodRx coupon. However, prices may vary depending on the pharmacy and your location. To reduce costs, consider using GoodRx or similar discount programs to find the most affordable option for your prescription.

Possible Alternatives to Dicyclomine

If Dicyclomine is not suitable for you, there are alternative treatments and lifestyle adjustments that may help manage your condition. Always consult your healthcare provider before making any changes to your treatment plan. Our telemedicine providers can guide you through these alternatives to ensure you receive the best care tailored to your specific needs.

Alternatives for Common Conditions

1. Irritable Bowel Syndrome (IBS): Alternatives include fiber supplements, probiotics, and medications such as lubiprostone (Amitiza) or linaclotide (Linzess). Lifestyle changes, including stress management, regular exercise, and dietary adjustments (e.g., avoiding trigger foods), can also be highly effective.
2. Gastrointestinal Spasms: Antispasmodic medications like hyoscyamine (Levsin) or peppermint oil supplements may provide relief. Additionally, relaxation techniques and warm compresses can help ease symptoms.
3. Colitis: Anti-inflammatory medications such as mesalamine (Asacol) or corticosteroids are often prescribed. Dietary modifications and probiotics may also play a role in symptom management.
4. Diverticulitis: Treatment typically involves antibiotics and a high-fiber diet. In more severe cases, surgery may be necessary.
5. Peptic Ulcer Disease: Proton pump inhibitors (PPIs) like omeprazole (Prilosec) or H2 blockers such as ranitidine (Zantac) are commonly used. Avoiding NSAIDs and managing stress can also help prevent ulcers from developing or worsening.
6. Functional Dyspepsia: Medications like metoclopramide (Reglan) or PPIs may alleviate symptoms. Dietary changes, such as eating smaller meals and avoiding spicy or fatty foods, can also be beneficial.
7. Pancreatitis: Treatment often includes pain management, IV fluids, and dietary adjustments. Severe cases may require hospitalization for more intensive care.
8. Biliary Colic: Pain relief medications are commonly used, and in some cases, gallbladder removal surgery (cholecystectomy) may be recommended.
9. Gastroesophageal Reflux Disease (GERD): Alternatives include PPIs like esomeprazole (Nexium) or H2 blockers. Lifestyle modifications, such as avoiding large meals, reducing alcohol consumption, and elevating the head of your bed, can also help manage symptoms effectively.
10. Abdominal Cramps: Over-the-counter pain relievers like acetaminophen (Tylenol) or antispasmodic medications may provide relief. Warm baths and relaxation techniques can also help reduce discomfort.

Recent Updates on Dicyclomine Research

Recent studies on Dicyclomine have focused on its effectiveness in treating irritable bowel syndrome (IBS) and other gastrointestinal disorders. A 2022 study emphasized that Dicyclomine remains a reliable option for alleviating abdominal pain and discomfort in IBS patients, particularly when combined with dietary modifications. Ongoing research is also exploring the potential benefits of using Dicyclomine in combination with other medications to enhance symptom management for gastrointestinal spasms and functional dyspepsia.
