Dosage must be adjusted to individual patient needs.

2.1 Intramuscular Dosage and Administration in Adults

BENTYL Intramuscular Injection must be administered via intramuscular route only. Do not administer by any other route.

The recommended intramuscular dose is 10 mg to 20 mg four times a day [see Clinical Pharmacology (12)].

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.

2.2 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.
