ic disorders: confusional state, nervousness
Reproductive system and breast disorders: suppressed lactation
Respiratory, thoracid and mediastinal disorders: dyspnoea, nasal congestion
Skin and subcutaneous tissue disorder: dermatitis allergic, erythema, rash
6.3 Adverse Reactions Reported with Similar Drugs with Anticholinergic/Antispasmodic Action
Gastrointestinal: anorexia,
Central Nervous System: tingling, numbness, dyskinesia, speech disturbance, insomnia
Peripheral Nervous System: With overdosage, a curare-like action may occur (i.e., neuromuscular blockade leading to muscular weakness and possible paralysis).
Ophthalmologic: diplopia, increased ocular tension
Dermatologic/Allergic: urticaria, itching, and other dermal manifestations;
Genitourinary: urinary hesitancy, urinary retention in patients with prostatic hypertrophy
Cardiovascular: hypertension
Respiratory: apnea
Other: decreased sweating, sneezing, throat congestion, impotence. With the injectable form, there may be temporary sensation of light-headedness. Some local irritation and focal coagulation necrosis may occur following the intramuscular injection of BENTYL.
7 DRUG INTERACTIONS
7.1 Antiglaucoma Agents
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 corticosteriods. Use of BENTYL in patients with glaucoma is not recommended [see Contraindications (4)].
7.2 Other Drugs with Anticholinergic Activity
The following agents may increase certain actions or side effects of anticholinergic drugs including BENTYL: amantadine, antiarrhythmic agents of Class I (e.g., quinidine), antihistamines, antipsychotic agents (e.g., phenothiazines), benzodiazepines, MAO inhibitors, narcotic analgesics (e.g., meperidine), nitrates and nitrites, sympathomimetic agents, tricyclic antidepressants, and other drugs having anticholinergic activity.
7.3 Other Gastrointestinal Motility Drugs
Interaction with other gastrointestinal motility drugs may antagonize the effects of drugs that alter gastrointestinal motility, such as metoclopraminde.
7.4 Effect of Antacids
Because antacids may interfere with the absorption of anticholinergic agents including BENTYL, simultaneous use of these drugs should be avoided.
7.5 Effect on Absorption of Other Drugs
Anticholinergic agents may affect the gastrointestinal absorption of various drugs by affecting the gastrointestinal motility, such as slowly dissolving dosage forms of digoxin; increased serum digoxin concentration may result.
7.6 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.
8 USE IN SPECIFIC POPULATIONS
8.1 Pregnancy
Pregnancy Category B
Adequate and well-controlled studies have not been conducted with BENTYL in pregnant women at the recommended doses of 80 to 160 mg/day. However, epidemiologic studies did not show an increased risk of structural malformations amoung babies born to women who took products containing dicyclomine hydrochloride at doses up to 40 mg/day during the first trimester of pregnancy.
