Lidotral 2% Spray

Lidotral® 2% Spray contains 20 mg of Lidocaine HCl per gram in a vehicle of Acrylates/C10-30 Alkyl Acrylate Crosspolymer, Aminomethyl Propanol, Aqua (Purified Water), Benzyl Alcohol, Ethyl Alcohol, PEG-8, Rosmarinus Officinalis (Rosemary) Leaf Oil, Fragrance.

Lidocaine HCI is chemically designated as acetamide, 2-(diethylamino)-N-(2,6-dimethylphenyl), and has the following structure:

Drug

Lidotral® 2% Spray is a combination of ingredients with analgesics and anesthetic properties used in a unique way to maximize its pain-relieving effects to aid in addition to other therapies. This offers long lasting relief for a variety of pain conditions.

For the temporary relief of pain and itching associated with minor burns, sunburn, minor cuts, scrapes, insect bites, and minor skin irritation.

Pharmacodynamics
Lidocaine is a common local anesthetic that relieves itching, burning, and pain. Topically, it blocks both initiation and conduction or nerve impulses by decreasing ionic flux through the neuronal membrane. Since it penetrates the skin, it creates an anesthetic effect by not just preventing pain signals from propagating to the brain out by stopping them before they begin.

Tuberculosis or fungal lesions of the skin vaccinia, varicella and acute herpes simplex and in persons who have shown hypersensitivity to any of its components. Lidocaine is contraindicated in patients with a known history of hypersensitivity to local anesthetics of the amide type.

For external use only.Not for ophthalmic use.

Allergic Reactions:Patients allergic to para-aminobenzoic acid derivatives (procaine, tetracaine, benzocaine, etc.) have not shown cross sensitivity to lidocaine. However, Lidotral® 2% Spray should be used with caution in patients with a history of drug sensitivities, especially if the etiologic agent is uncertain.

Non-intact Skin: Application to broken or inflamed skin, although not tested, may result in higher blood concentrations of lidocaine from increased absorption. Lidotral® 2% Spray is only recommended for use on intact skin.

External Heat Sources: Placement of external heat sources, such as heating pads or electric blankets, over Lidotral® 2% Spray is not recommended as this has not been evaluated and may increase plasma lidocaine levels.

Eye Exposure: The contact of Lidotral® 2% Spray with eyes, although not studied, should be avoided based on thefindings of severe eye irritation with the use of similar products in animals. If eye contact occurs, immediately wash out the eye with water or saline and protect the eye until sensation returns.

Antiarrhythmic Drugs: Lidotral® 2% Spray should be used with caution in patients receiving Class I antiarrhythmic drugs (such as tocainide and mexiletine) since the toxic effects are additive and potentially synergistic.
Local Anesthetics: When Lidotral® 2% Spray is used concomitantly with other products containing local anesthetic agents, the amount absorbed from all formulations must be considered.

Carcinogenesis: A minor metabolite, 2,6-xylidine, has been found to be carcinogenic in rats. The blood concentration of this metabolite is negligible following application of lidocaine.
Mutagenesis: Lidocaine HCl is not mutagenic in Salmonella/mammalian microsome test nor clastogenic in chromosome aberration assay with human lymphocytes and mouse micronucleus test.
Impairment of Fertility: The effect of lidocaine on fertility has not been studied.

Teratogenic Effects: Pregnancy Category B. Lidocaine has not been studied in pregnancy. Reproduction studies with lidocaine have been performed in rats at doses up to 30 mg/kg subcutaneously and have revealed no evidence of harm to the fetus due to lidocaine. There are, however, no adequate and well- controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, lidocaine should be used during pregnancy only if clearly needed.
Labor and Delivery
Lidocaine has not been studied in labor and delivery. Lidocaine is not contraindicated in labor and delivery. Should lidocaine be used concomitantly with other products containing lidocaine, total doses contributed by all formulations must be considered.

Lidocaine has not been studied in nursing mothers. Lidocaine is excreted in human milk, and the milk: plasma ratio of lidocaine is 0.4. Caution should be exercised when lidocaine is administered to a nursing woman.

Safety and effectiveness in pediatric patients have not been established.

ADVERSE REACTIONS
Application Site Reactions
Even though adverse reactions are rare, a very small percentage of patients experience an unpleasant burning sensation, redness, warmth, or stinging. It is advisable to apply a small amount on the forearm prior to first use. If any of these effects persists or worsens, contact your physician or pharmacist immediately. This medication is not absorbed systemically but if any serious side effects (i.e. rash, itching/swelling, severe dizziness) are experienced, discontinue use immediately and contact your pharmacist or physician. This is not a complete list of all side effects that may occur. You may report side effects to the FDA at 800-FDA-1088 or at www.fda.gov/medwatch.
Allergic Reactions
Allergic and anaphylactoid reactions associated with lidocaine, although rare, can occur. They are characterized by angioedema, bronchospasm, dermatitis, dyspnea, hypersensitivity, laryngospasm, pruritus, shock, and urticaria. If they occur, they should be managed by conventional means. The detection of sensitivity by skin testing is of doubtful value.
Other Adverse Events
Due to the nature and limitation of spontaneous reports in post marketing surveillance, causality has not been established for additional reported adverse events including: Asthenia, confusion, disorientation, dizziness, headache, hyperesthesia, hypoesthesia, lightheadedness, metallic taste, nausea, nervousness, pain exacerbated, paresthesia, somnolence, taste alteration, vomiting, visual disturbances such as blurred vision, flushing, tinnitus, and tremor.
Systemic (Dose-Related) Reactions
Systemic adverse reactions following appropriate use of lidocaine is unlikely, due to the small dose absorbed (see CLINICAL PHARMACOLOGY, Pharmacokinetics). Systemic adverse effects of lidocaine are similar in nature to those observed with other amide local anesthetic agents, including CNS excitation and/or depression (light-headedness, nervousness, apprehension, euphoria, confusion, dizziness, drowsiness, tinnitus, blurred or double vision, vomiting, sensations of heat, cold or numbness, twitching, tremors, convulsions, unconsciousness, respiratory depression and arrest). Excitatory CNS reactions may be brief or not occur at all, in which case the first manifestation may be drowsiness merging into unconsciousness. Cardiovascular manifestations may include bradycardia, hypotension and cardiovascular collapse leading to arrest.
To report SUSPECTED ADVERSE REACTIONS, contact Actavis at 1-800- 272-5525 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch for voluntary reporting of adverse reactions.

Lidocaine overdose from cutaneous absorption is rare, but could occur. If there is any suspicion of lidocaine overdose (see ADVERSE REACTIONS, Systemic Reactions), drug blood concentration should be checked. The management of overdose includes close monitoring, supportive care, and symptomatic treatment. Dialysis is of negligible value in the treatment of acute overdose with lidocaine.
In the absence of massive topical overdose or oral ingestion, evaluation of symptoms of toxicity should include consideration of other etiologies for the clinical effects, or over dosage from other sources of lidocaine or other local anesthetics.
The oral LD50 of lidocaine HCl is 459 (346 to 773) mg/kg (as the salt) in non-fasted female rats and 214 (159 to 324) mg/kg (as the salt) in fasted female rats, which are equivalent to roughly 4000 mg and 2000 mg, respectively, in a 60 to 70 kg man based on the equivalent surface area dosage conversion factors between species.

Adults & children 4 years of age and older: spray to the affected area(s) two or three times daily or as directed by alicensed healthcare practitioner.
Children under 4 years of age: consult a licensed healthcare practitioner.
Apply Lidotral® 2% Spray to intact skin to cover the most painful area. Smaller areas of treatment are recommended in a debilitated patient, or a patient with impaired elimination.
When Lidotral® 2% Spray is used concomitantly with other products containing local anesthetic agents, the amount absorbed from all formulations must be considered.
