How Supplied


BENTYL® (dicyclomine hydrochloride) is indicated for the treatment of patients with functional bowel/irritable bowel syndrome.


Dosage must be adjusted to individual patients needs.

Oral Dosage And Administration In Adults

The recommended initial dose is 20 mg four times a day. After one week treatment with the initial dose, the dose may be increased to 40 mg four times a day unless side effects limit dosage escalation. If efficacy is not achieved within 2 weeks or side effects require doses below 80 mg per day, the drug should be discontinued. Documented safety data are not available for doses above 80 mg daily for periods longer than 2 weeks.

Intramuscular Dosage And Administration In Adults

BENTYL Intramuscular Injection must be administered via intramuscular route only. Do not administer by an other route. The recommended intramuscular dose is 10 mg to 20 mg four times a day. [see CLINICAL PHARMACOLOGY]

The intramuscular injection is to be used only for 1 or 2 days when the patient cannot take oral medication.

Intramuscular injection is about twice as bioavailable as oral dosage forms.

Preparation For Intramuscular Administration

Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit.

Aspirate the syringe before injecting to avoid intravascular injection, since thrombosis may occur if the drug is inadvertently injected intravascularly.
