Bentyl, which is generically prescribed as dicyclomine, is commonly used to treat functional bowel and irritable bowel syndrome. Bentyl relieves the spasms which occur in the bowels and gastrointestinal tract. Bentyl can be used to treat other bowel issues.

Bentyl is not appropriate for everyone. A thorough medical history should be assessed prior to prescribing this medication. Patients with a medical history which includes a urinary tract blockage, intestinal blockage, reflux disease, glaucoma, or myasthenia gravis can not take Bentyl. Patients with a medical history which includes liver disease, kidney disease, tingling or numbness of the extremities, ulcerative colitis, thyroid problems, irregular heart rate, high blood pressure, heart disease, hiatal hernia, or enlarged prostate may not be able to take Bentyl or may require careful monitoring while undergoing drug therapy with Bentyl, depending on the condition and the severity of the condition.

The American Food and Drug Administration rated Bentyl as a pregnancy risk category B. While it is not likely that Bentyl will cause harm or birth defects in unborn babies, it is imperative that women who are nursing do not take this medication. Nursing babies under six month of age develop serious breathing problems, as Bentyl does pass through the mother’s breast milk and causes harm to nursing babies. The prescribing physician should discuss whether the benefits outweigh the risks when prescribing this medication to a pregnant woman and should avoid prescribing this medication to nursing women.

There is a risk of side effects associated with Bentyl, some of which are severe. A patient who is experiencing a serious side effect or an allergic reaction should seek immediate emergency medical attention. An allergic reaction will present with symptoms that include facial swelling, including swelling of the lips, mouth, throat, or tongue, hives, and difficulty breathing. Other serious side effects which require emergency medical care include irregular heart rates or uneven and fast heart rates.

Other less serious side effects typically do not require emergency medical attention but should be reported to the prescribing physician. Patients should be encouraged to report all side effects. Less serious side effects include symptoms such as weakness, nervousness, headaches, dizziness, lightheadedness, blurry vision, dilated pupils, rash, itching, difficulty urinating, decreased sweating, congestion, or dry mouth. Less serious side effects can often be reduced to a more tolerable level by reducing the dosage of Bentyl.

Bentyl should be taken exactly as it has been prescribed by the physician. If the patient misses a dose, the dose should be taken as soon as it is remembered. However, if it is almost time for the next scheduled dose, the missed dose should be skipped to avoid a potential overdose. The patient should never take a double dose of this medication. If an overdose is suspected, the patient should seek immediate emergency medical treatment. An overdose will present with symptoms which include nausea, vomiting, headache, blurry vision, dilated pupils, dry mouth, difficulty swallowing, hot skin, dry skin, dizziness, drowsiness, confusion, anxiety, seizures, weak pulse, and irregular heart rate.

There is a risk of negative drug interactions associated with Bentyl. A thorough medical history should be understood prior to prescribing this medication. Patients should be urged to inquire with the prescribing physician before taking any new medications, including over the counter medications and herbal remedies. Medications that have a known interaction with Bentyl include quinidine, amantadine, antihistamines, decongestants, MAO inhibitors, phenothiazines, benzodiazepines, narcotic analgesics, nitrates, tricyclic antidepressants, and antacids.
