Important Safety Information for Dicyclomine Hydrochloride Oral Solution, USP, 10 mg/5 mL:
Dicyclomine hydrochloride is contraindicated in infants less than 6 months of age, nursing mothers and in patients with:
- Unstable cardiovascular status in acute hemorrhage
- Myasthenia gravis
- Obstructive uropathy
- Obstructive disease of the gastrointestinal tract
- Severe ulcerative colitis
- Reflux esophagitis
WARNINGS AND PRECAUTIONS
- Use dicyclomine hydrochloride with caution in patients with conditions characterized by tachyarrhythmia such as thyrotoxicosis, congestive heart failure and in cardiac surgery, where they may further accelerate the heart rate. Investigate any tachycardia before administration of dicyclomine hydrochloride. Care is required in patients with coronary heart disease, as ischemia and infarction may be worsened, and in patients with hypertension.
Peripheral and Central Nervous System (CNS)
- Peripheral effects of dicyclomine hydrochloride include dryness of the mouth with difficulty in swallowing and talking, thirst, reduced bronchial secretions, dilatation of the pupils (mydriasis) with loss of accommodation (cycloplegia) and photophobia, flushing and dryness of the skin, transient bradycardia followed by tachycardia, with palpitations and arrhythmias, and difficulty in micturition, as well as reduction in the tone and motility of the gastrointestinal tract leading to constipation.
In the presence of high environmental temperature, heat prostration can occur with drug use. Use with caution in patients with fever. If symptoms occur, the drug should be discontinued and supportive measures instituted. Use with caution in patients with autonomic neuropathy.
CNS signs and symptoms include confusion, disorientation, short-term amnesia, hallucinations, dysarthria, ataxia, coma, euphoria, fatigue, insomnia, agitation and mannerisms and inappropriate affect. Psychosis has been reported in sensitive individuals given anticholinergic drugs.
Dicyclomine hydrochloride may produce drowsiness, dizziness or blurred vision. Warn the patient not to engage in activities requiring mental alertness, such as operating a motor vehicle or other machinery or performing hazardous work while taking dicyclomine hydrochloride.
With overdosage, a curare-like action may occur. Do not give dicyclomine hydrochloride to patients with myasthenia gravis except to reduce adverse muscarinic effects of an anticholinesterase.
Diarrhea may be an early symptom of incomplete intestinal obstruction, especially in patients with ileostomy or colostomy. In this instance, treatment with this drug would be inappropriate and possibly harmful.
Rarely, development of Ogilvie’s Syndrome has been reported.
Toxic Dilatation of Intestinemegacolon
Toxic dilatation of intestine and intestinal perforation is possible when anticholinergic agents are administered in patients with Salmonella dysentery.
Use with caution in patients with ulcerative colitis. Large doses may suppress intestinal motility to the point of producing a paralytic ileus and the use of this drug may precipitate or aggravate the serious complication of toxic megacolon. Contraindicated in patients with severe ulcerative colitis.
Use with caution in patients with known or suspected prostatic enlargement.
Hepatic and Renal Disease
Use with caution in patients with known hepatic and renal impairment.
Use with caution in elderly patients who may be more susceptible to its adverse effects.
The pattern of adverse effects seen with dicyclomine hydrochloride is dose-related and usually reversible when treatment is discontinued.
The most serious adverse reactions reported include cardiovascular and CNS symptoms.
Anticholinergics antagonize the effects of antiglaucoma agents. Anticholinergic drugs in the presence of increased intraocular pressure may be hazardous when taken concurrently with agents such as corticosteroids. Use of dicyclomine hydrochloride in patients with glaucoma is not recommended.
Other Drugs With Anticholinergic Activity
Amantadine, antiarrhythmic agents of Class I, antihistamines, antipsychotic agents, benzodiazepines, MAO inhibitors, narcotic analgesics, nitrates and nitrites, sympathomimetic agents, tricyclic antidepressants and other drugs having anticholinergic activity may increase certain actions or side effects of anticholinergic drugs, including dicyclomine hydrochloride.
Other Gastrointestinal Motility Drugs
Interaction with other gastrointestinal motility drugs may antagonize the effects of drugs that alter gastrointestinal motility.
Effect of Antacids
Simultaneous use of dicyclomine hydrochloride and antacids should be avoided.
Effect of Absorption of Other Drugs
Anticholinergic agents may affect gastrointestinal absorption of various drugs by affecting gastrointestinal motility, such as slowly dissolving dosage forms of digoxin; increased serum digoxin concentration may result.
Effect on Gastric Acid Secretion
The inhibiting effects of anticholinergic drugs on gastric hydrochloric acid secretion are antagonized by agents used to treat achlorhydria and those used to test gastric secretion.
USE IN SPECIFIC POPULATIONS
Pregnancy Category B
Adequate and well-controlled studies have not been conducted with dicyclomine hydrochloride in pregnant women at the recommended doses of 80 to 160 mg/day. This drug should be used during pregnancy only if clearly needed.
Dicyclomine hydrochloride is contraindicated in women who are breastfeeding.
Dicyclomine hydrochloride is contraindicated in infants younger than 6 months of age. Safety and effectiveness in other pediatric patients have not been established.
Dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range in adults, reflecting the greater frequency of decreased hepatic, renal or cardiac function and of concomitant disease or other drug therapy.
Because elderly patients are more likely to have decreased renal function, care should be taken to determine the appropriate dose. Renal function should be monitored.
Patients with Renal Impairment
Effects of renal impairment on pharmacokinetics (PK), safety and efficacy of dicyclomine hydrochloride have not been studied. However, dicyclomine hydrochloride is known to be substantially excreted by the kidney and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Administer with caution in these patients.
Patients with Hepatic Impairment
Effects of renal impairment on PK, safety and efficacy of dicyclomine hydrochloride have not been studied. Administer with caution in patients with hepatic impairment.
DOSAGE AND ADMINISTRATION
Dosage must be adjusted to individual patient needs. If efficacy is not achieved within 2 weeks or side effects require doses below 80 mg/day, the drug should be discontinued. Documented safety data are not available for doses above 80 mg/day for periods longer than 2 weeks.
