Instructions for Subgingival Delivery:
- Remove the shipping cap, discard and replace with Luer-lock dispensing cap. Note: Once dispensing cap is in place, it should not be removed.
- Remove the small cap from the Luer-lock port. Retain for replacement after use.
- Lock a 1.2 mL Luer-lock syringe into the port.
- Invert the bottle and slowly draw liquid (0.4 mL maximum) into syringe. If air is drawn into syringe, push the liquid back into the bottle and slowly redraw liquid into syringe.
- Holding bottle upright, remove the syringe from the port and replace the small port cap.
- Attach a 27 ga Vista-Probe Tip to the syringe. The tip may be bent to improve access. Do not bend tip more than once in the same location. If more than a 45 degree angle is desired, bend in two locations. Bending at the hub may increase the risk of breakage.
- Apply Cetacaine Liquid drop-wise to accessible mucous membrane (such as the buccal and lingual sulcus) by slowly depressing the syringe plunger.
- Wait 1 minute for maximum anesthesia before beginning procedure. The duration of anesthesia is typically 3--60 minutes, when used as directed. Discard syringe and tip after use.

Cetacaine Spray should be applied for approximately one second or
less for normal anesthesia. Only a limited quantity of Cetacaine is
required for anesthesia. Spray in excess of two seconds is
contraindicated. Average expulsion rate of residue from spray, at normal
temperatures, is 200 mg per second.
To apply, insert the Jetco cannula (J-4) firmly onto the protruding plastic
stem on the bottle and press the cannula forward to actuate the spray
valve. The cannula may be removed and reinserted as many times as
required for cleaning, or sterilization, and is autoclavable.
Cetacaine Liquid Apply 200 mg (approximately 6 – 7 drops or 0.2 cc)
with a cotton applicator or directly to tissue. Do not hold the cotton
applicator in position for extended periods of time, since local reactions
to benzoate topical anesthetics are related to the length of time
of application. Liquid in excess of 400 mg (approx. 12 – 14 drops or
0.4 cc) is contraindicated.
*See Cetacaine Liquid Kit instructions for additional directions for application
by Luer-lock syringe and applicator tip.
Cetacaine Gel Apply 200 mg of gel (a bead approximately 0.5 inch
(13 mm) in length and 3/16 inch (5 mm) in diameter) and spread thinly
and evenly over the application area. Gel in excess of 400 mg (a bead
approximately 1 inch (26 mm) in length and 3/16 inch (5 mm) in diameter)
is contraindicated.
An appropriate pediatric dosage has not been established for Cetacaine
Spray, Liquid or Gel.
Dosages should be reduced in the debilitated elderly, acutely ill, and
very young patients.
Tissue need not be dried prior to application of Cetacaine. Cetacaine
should be applied directly to the site where pain control is required.
Anesthesia is produced within one minute with an approximate
duration of thirty minutes. Each 200 mg dose of Cetacaine (Spray
residue, Liquid or Gel) contains 28 mg of benzocaine, 4 mg of butamben
and 4 mg of tetracaine HCl.
