Dicycloverin Uses, Dosage, Side Effects, Food Interaction and all others data.
Dicycloverine HCl relieves smooth muscle spasm in the GI and urinary tract. This effect is partly due to antimuscarinic action and partly direct action on the smooth muscle.
Dicycloverin is an anticholinergic drug used to relax the smooth muscles of the intestines. It's duration of action is not especially long as it is usually taken 4 times daily with individual doses of 20-40mg orally or 10-20mg by intramuscular injection. Dicycloverin should not be administered intravenously.

How Dicycloverin works
Dicycloverin achieves its action partially through direct antimuscarinic activity of the M1, M3, and M2 receptors; and partially through antagonism of bradykinin and histamine. Dicycloverin non-competitively inhibits the action of bradykinin and histamine, resulting in direct action on the smooth muscle, and decreased strength of contractions seen in spasms of the ileum.

Precaution
Use with caution in patients with autonomic neuropathy, hepatic or renal disease, ulcerative colitis, coronary heart disease, congestive heart failure, cardiac tachyarrhythmia, known or suspected prostatic hypertrophy.
Interaction
The following agents may increase certain actions or side-effects of Dicycloverine-antiarrhythmic agents, antihistamines, antipsychotic agents, benzodiazepines, MAO inhibitors, narcotic analgesics, nitrates and nitrites, sympathomimetic agents, tricyclic antidepressants and other drugs having anticholinergic activity.
Food Interaction
- Avoid alcohol. Alcohol may increase drowsiness caused by dicyclomine.
- Drink plenty of fluids. Dicycloverin may reduce sweating, increasing the risk of overheating in warm weather or during exercise.
Dicycloverin Alcohol interaction
[Moderate] GENERALLY AVOID:
Use of anticholinergic agents with alcohol may result in sufficient impairment of attention so as to render driving and operating machinery more hazardous.
In addition, the potential for abuse may be increased with the combination.
The mechanism of interaction is not established but may involve additive depressant effects on the central nervous system.
No effect of oral propantheline or atropine on blood alcohol levels was observed in healthy volunteers when administered before ingestion of a standard ethanol load.
However, one study found impairment of attention in subjects given atropine 0.5 mg or glycopyrrolate 1 mg in combination with alcohol.
Alcohol should generally be avoided during therapy with anticholinergic agents.
Patients should be counseled to avoid activities requiring mental alertness until they know how these agents affect them.
Dicycloverin Hypertension interaction
[Minor] Cardiovascular effects of anticholinergics may exacerbate hypertension.
Therapy with anticholinergic agents should be administered cautiously in patients with hypertension.
