Drug Detail:Radiaguard (Lidocaine topical [ lye-doe-kane-top-i-kal ])
Drug Class: Topical anesthetics
Usual Adult Dose for Anesthesia
2% viscous solution: Gargle 15 mL, undiluted, and spit out or swallow, no less than every 3 hours
Maximum dose: 300 mg for normal healthy adult - not to exceed 4.5 mg/kg (2 mg/lb), or 8 doses in 24 hours
Comments:
- Adjust dose based on patient's age, weight, and physical condition.
Uses:
- Topical anesthesia of irritated or inflamed mucous membranes of the mouth and pharynx
- Reducing gagging during dental x-rays and impressions
----
2% jelly:
Endotracheal intubation: Apply a moderate amount of jelly to the external surface of the endotracheal tube shortly before insertion
Maximum dose: 600 mg in any 12 hour period
Comments:
- Avoid introducing jelly into tube lumen due to possibility of inner lumen occlusion.
- Do not use the jelly to lubricate endotracheal stylettes.
- Avoid use of endotracheal tubes with dried jelly on the external surface due to lack of lubricating effect.
4% solution: Spray 1 to 5 mL (40 to 200 mg) to the desired area. May also be applied with cotton applicators or by instillation
Maximum dose: 300 mg for normal healthy adult - not to exceed 4.5 mg/kg (2 mg/lb)
Comments:
- When spraying, transfer solution to an atomizer.
- Dosage varies and depends on the area to be anesthetized, vascularity of the tissues, individual tolerance, and technique.

Maximum dose: 5 g per single application (approximately 6 inches of ointment squeezed from the tube); 20 g total in any day
Comments:
- Adjust dose based on patient's age, weight, and physical condition.
- In dentistry, apply to previously dried oral mucosa; subsequent saliva removal with cotton rolls or saliva ejector minimizes dilution, permits maximum penetration, and minimizes swallowing of the drug.

Precautions
US BOXED WARNING:
- Do Not Use Lidocaine to Treat Teething Pain in Children.
- Prescription oral viscous lidocaine 2% solution is not approved for, and should not be used for, treating infants & children with teething pain.
- Its use for this purpose has resulted in serious harm and deaths.
- Rubbing topical pain relievers on gums is not useful or effective because they wash out of the baby's mouth within minutes, and when too much is swallowed, it can result in seizures, severe brain injury, and cardiac toxicity.
- The American Academy of Pediatrics recommends the use of chilled teething rings or rubbing the child's gums with a finger to relieve the symptoms of teething pain, instead of the use of topical medications.
5% Patch: Safety and efficacy have not been established in patients younger than 18 years.
0.5% Intradermal injection system: Safety and efficacy have not been established in patients younger than 3 years.
Consult WARNINGS section for additional precautions.

Other Comments
Administration advice:
- For topical use only.
- Avoid contact with eyes.
- Wash hands after handling patch.
- Apply patch immediately after removal from protective envelope.
Storage requirements:
- Do not store patch outside the sealed envelope.
General:
- Keep out of reach of children.
- Even a used patch contains a large amount of lidocaine (at least 665 mg)
- Store and dispose of patches out of the reach of children, pets, and others.
- When using with other local anesthetics, the amount absorbed from all formulations must be considered.
Patient advice:
- Strictly adhere to dosing instructions.
- Keep medicines away from children.
- When used in the mouth, be aware that topical anesthesia may impair swallowing and enhance the danger of aspiration.
- Food should not be ingested for 60 minutes following use in the mouth or throat area; this is particularly important in children because of their frequency of eating.
- Numbness of the tongue or buccal mucosa enhances the danger of unintentional biting trauma: food and chewing gum should not be taken while the mouth or throat area is anesthetized.
- Do not use over the counter lidocaine products for more than a week unless directed by a physician.
- Fold used patches so the adhesive side sticks to itself; discard where children or pets cannot get to them.
- Hemorrhoids: Stop use and ask a doctor for rectal bleeding, condition worsening or not improving within 7 days, allergic reactions, symptom being treated not subsiding, redness, irritation, swelling, pain, or other symptoms developing or increasing, or symptoms clear up and return within a few days.
