Articaine HCl and Epinephrine is a combination of articaine HCl, an amide local anesthetic, and epinephrine, a vasoconstrictor, is indicated for local, infiltrative, or conductive anesthesia in both simple and complex dental procedures. in adults and pediatric patients 4 years of age or older.
⏱️ Dosage and Administration ▾
2 DOSAGE AND ADMINISTRATION For dental procedures by intraoral submucosal infiltration or nerve block. ( 2.1 ) - For infiltration: 0.5-2.5 mL (20-100 mg articaine HCl) - For nerve block: 0.5-3.4 mL (20-136 mg articaine HCl) - For oral surgery: 1.0-5.1 mL (40-204 mg articaine HCl) For most routine dental procedures, Articaine HCl and Epinephrine containing 1:200,000 is preferred. However, when more pronounced hemostasis or improved visualization of the surgical field are required, Articaine HCl and Epinephrine containing epinephrine 1:100,000 may be used.
( 2.1 ) Maximum recommended dosages ( 2.2 ): - Healthy adults: 7 mg/kg of articaine HCl and 0.0017mg/kg of epinephrine (equivalent to 0.175 mL/kg for either product presentation, articaine HCl and epinephrine 1:100,000 or 1:200,000) - Pediatric patien ts 4-16 years: 7 mg/kg of articaine HCl and 0.0017mg/kg of epinephrine (equivalent to 0.175 mL/kg for either product presentation, articaine HCl and epinephrine 1:100,000 or 1:200,000)
2.1Important Dosage Information Table 1 summarizes the recommended dosages of Articaine HCl and Epinephrine administered by intraoral submucosal infiltration or nerve block for various types of anesthetic dental procedures in healthy adults and pediatric patients. Table 1: Recommended Dosages for Both Strengths Articaine HCl and Epinephrine Injection Procedure Volume (mL) Total dose of articaine HCl (mg) Infiltration 0.5 mL to 2.5 mL 20 mg to 100 mg Nerve block 0.5 mL to 3.4 mL 20 mg to 136 mg Oral surgery 1 mL to 5.1 mL 40 mg to 204 mg The recommended dosages of Articaine HCl and Epinephrine in healthy adults serve only as a guide to the amount of anesthetic required for most routine dental procedures.
The dosages to be used in adults depend on several factors such as type and extent of surgical procedure, depth of anesthesia, degree of muscular relaxation, and condition of the patient. In all cases, administer the lowest dosage that will produce the desired result. The dosages of Articaine HCl and Epinephrine to be used in pediatric patients aged 4 to 16 years old are determined by the age and weight of the patient and the type of dental procedure.
For most routine dental procedures, Articaine HCl and Epinephrine containing epinephrine 1:200,000 is preferred. However, when more pronounced hemostasis or improved visualization of the surgical field are required, Articaine HCl and Epinephrine containing epinephrine 1:100,000 may be used.
2.2Maximum Recommended Dosages Healthy Adults: The maximum recommended dosage of Articaine HCl and Epinephrine is 7 mg/kg of articaine and 0.0017mg/kg of epinephrine (equivalent to 0.175 mL/kg for either product presentation, articaine HCl and 1:100,000 or 1:200,000 epinephrine).

⛔ Contraindications ▾
4 CONTRAINDICATIONS Articaine HCl and Epinephrine is contraindicated in patients who are hypersensitive to products containing sulfites. Products containing sulfites may cause allergic-type reactions including anaphylactic symptoms and life-threatening or less severe asthmatic episodes in certain susceptible people. Sulfite sensitivity is seen more frequently in asthmatic than in non-asthmatic people [see Warnings and Precautions (5.5) ].
Known hypersensitivity to sulfite. ( 4 )
⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Accidental Intravascular Injection: May be associated with convulsions followed by coma and respiratory arrest. Resuscitative equipment, oxygen and other resuscitative drugs should be available. ( 5.1 ) Systemic Toxicity: Systemic absorption of Articaine HCl and Epinephrine can produce effects on the central nervous and cardiovascular systems.
( 5.2 ) Vasoconstrictor Toxicity: Local anesthetic solutions like Articaine HCl and Epinephrine that contain a vasoconstrictor should be used cautiously, especially in patients with impaired cardiovascular function or vascular disease. ( 5.3 ) Methemoglobinemia: Cases of methemoglobinemia have been reported in association with local anesthetic use. ( 5.4 )
5.1Accidental Intravascular Injection Accidental intravascular injection of Articaine HCl and Epinephrine may be associated with convulsions, followed by central nervous system or cardiorespiratory depression and coma, progressing ultimately to respiratory arrest. Dental practitioners who employ local anesthetic agents including Articaine HCl and Epinephrine should be well versed in diagnosis and management of emergencies that may arise from their use. Resuscitative equipment, oxygen, and other resuscitative drugs should be available for immediate use.
To avoid intravascular injection, aspiration should be performed before Articaine HCl and Epinephrine is injected. The needle must be repositioned until no return of blood can be elicited by aspiration. Note, however, that the absence of blood in the syringe does not guarantee that intravascular injection has been avoided.
Small doses of local anesthetics injected in dental blocks may produce adverse reactions similar to systemic toxicity seen with unintentional intravascular injections of larger doses. Confusion, convulsions, respiratory depression or respiratory arrest, and cardiovascular stimulation or depression have been reported. These reactions may be due to intra-arterial injection of the local anesthetic with retrograde flow to the cerebral circulation.
Patients receiving these blocks should be observed constantly. Resuscitative equipment and personnel for treating adverse reactions should be immediately available. Dosage recommendations should not be exceeded [see Dosage and Administration (2.1) ].
5.2Systemic Toxicity This includes toxicity arising from accidental intravascular injection of Articaine HCl and Epinephrine discussed in Section 5.1, as well as that related to higher systemic concentrations of local anesthetics or epinephrine [see Warnings and Precautions (5.3) ]. Systemic absorption of local anesthetics including Articaine HCl and Epinephrine can produce effects on the central nervous and cardiovascular systems. At blood concentrations achieved with therapeutic doses of Articaine HCl and Epinephrine, changes in cardiac conduction, excitability, refractoriness, contractility, and peripheral vascular resistance are minimal.
However, toxic blood concentrations of Articaine HCl and Epinephrine can depress cardiac conduction and excitability, which may lead to atrioventricular block, ventricular arrhythmias, and cardiac arrest, possibly resulting in fatalities. In addition, myocardial contractility is depressed and peripheral vasodilatation occurs, leading to decreased cardiac output and arterial blood pressure. Articaine HCl and Epinephrine should also be used with caution in patients with heart block as well as those with impaired cardiovascular function since they may be less able to compensate for functional changes associated with the prolongation of A-V conduction produced by these drugs.
Restlessness, anxiety, tinnitus, dizziness, blurred vision, tremors, depression, or drowsiness may be early warning signs of central nervous system toxicity. Careful and constant monitoring of cardiovascular and respiratory (adequacy of ventilation) vital signs and the patient's state of consciousness should be performed after each local anesthetic i…
🤒 Adverse Reactions ▾
6 ADVERSE REACTIONS Reactions to articaine are characteristic of those associated with other amide-type local anesthetics. Adverse reactions to this group of drugs may also result from excessive plasma levels (which may be due to overdosage, unintentional intravascular injection, or slow metabolic degradation), injection technique, volume of injection, or hypersensitivity or they may be idiosyncratic. The most common adverse reactions (incidence >2%) are headache and pain.

7 DRUG INTERACTIONS The administration of local anesthetic solutions containing epinephrine to patients receiving monoamine oxidase inhibitors, nonselective beta-adrenergic antagonists, or tricyclic antidepressants may produce severe, prolonged hypertension. Phenothiazines and butyrophenones may reduce or reverse the pressor effect of epinephrine. Concurrent use of these agents should be avoided; however, in situations when concurrent therapy is necessary, careful patient monitoring is essential [see Warnings and Precautions (5.2) ].
Patients who are administered local anesthetics are at increased risk of developing methemoglobinemia when concurrently exposed to the following drugs, which could include other local anesthetics: Table 5. Examples of Drugs Associated with Methemoglobinemia: Class Examples Nitrates/Nitrites nitric oxide, nitroglycerin, nitroprusside, nitrous oxide Local anesthetics articaine, benzocaine, bupivacaine, lidocaine, mepivacaine, prilocaine, procaine, ropivacaine, tetracaine Antineoplastic agents cyclophosphamide, flutamide, hydroxyurea, ifosfamide, rasburicase Antibiotics dapsone, nitrofurantoin, para-aminosalicylic acid, sulfonamides Antimalarials chloroquine, primaquine Anticonvulsants phenobarbital, phenytoin, sodium valproate Other drugs acetaminophen, metoclopramide, quinine, sulfasalazine Monoamine Oxidase Inhibitors, Nonselective Beta-Adrenergic Antagonists, or Tricyclic Antidepressants: May produce severe, prolonged hypertension ( 7 ) Phenothiazines and Butyrophenones: May reduce or reverse the pressor effect of epinephrine ( 7 )
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS Pregnancy: Based on animal studies, may cause fetal harm. ( 8.1 ) Nursing Mothers: Exercise caution when administering to a nursing woman. ( 8.3 ) Pediatric Use: Safety and effectiveness in pediatric patients below the age of 4 years have not been established. ( 8.4 )
8.1Pregnancy Teratogenic Effects - Pregnancy Category C. There are no adequate and well-controlled studies in pregnant women with Articaine HCl and Epinephrine. Articaine hydrochloride and epinephrine (1:100,000) has been shown to increase fetal deaths and skeletal variations in rabbits when given in doses approximately 4 times the maximum recommended human dose (MRHD).
Articaine HCl and Epinephrine should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. In embryo-fetal toxicity studies in rabbits, 80 mg/kg, subcutaneously (approximately 4 times the MRHD based on body surface area) caused fetal death and increased fetal skeletal variations, but these effects may be attributable to severe maternal toxicity, including seizures, observed at this dose. In contrast, no embryo-fetal toxicities were observed when articaine and epinephrine (1:100,000) was administered subcutaneously throughout organogenesis at doses up to 40 mg/kg in rabbits and 80 mg/kg in rats (approximately 2 times the MRHD based on body surface area).
In pre- and postnatal developmental studies subcutaneous administration of articaine hydrochloride to pregnant rats throughout gestation and lactation, at a dose of 80 mg/kg (approximately 2 times the MRHD based on body surface area) increased the number of stillbirths and adversely affected passive avoidance, a measure of learning, in pups. This dose also produced severe maternal toxicity in some animals. A dose of 40 mg/kg (approximately equal to the MRHD on a mg/m 2 basis) did not produce these effects.
A similar study using articaine and epinephrine (1:100,000) rather than articaine hydrochloride alone produced maternal toxicity, but no effects on offspring.
8.3Nursing Mothers It is not known whether Articaine HCl and Epinephrine is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when Articaine HCl and Epinephrine is administered to a nursing woman. When using Articaine HCl and Epinephrine, nursing mothers may choose to pump and discard breast milk for approximately 4 hours (based on plasma half life) following an injection of Articaine HCl and Epinephrine (to minimize infant ingestion) and then resume breastfeeding.
8.4Pediatric Use Safety and effectiveness of Articaine HCl and Epinephrine in pediatric patients below the age of 4 years have not been established. Safety of doses greater than 7 mg/kg (0.175 mL/kg) in pediatric patients has not been established. The safety and effectiveness of Articaine HCl and Epinephrine for local, infiltrative, or conductive anesthesia in both simple and complex dental procedures have been established in pediatric patients ages 4 to 16 years old.
Safety and effectiveness was established in clinical trials with 61 pediatric patients between the ages of 4 and 16 years administered articaine hydrochloride 4% and epinephrine 1:100,000 injections. Fifty-one of these patients received doses from 0.76 mg/kg to 5.65 mg/kg (0.9 to 5.1 mL) for simple dental procedures and 10 patients received doses between 0.37 mg/kg and 7.48 mg/kg (0.7 to 3.9 mL) for complex dental procedures. Approximately 13% of these pediatric patients required additional injections of anesthetic for complete anesthesia.
Dosages in pediatric patients should be reduced, commensurate with age, body weight, and physical condition [see Dosage and Administration (2.2) ].
8.5Geriatric Use In clinical trials, 54 patients between the ages of 65 and 75 years, and 11 patients 75 years and over received Articaine HCl and Epinephrine containing epinephrine 1:100,000. Among all patients between 65 and 75 years, doses from 0.43 mg/kg to…

🧓 Geriatric Use ▾
8.5Geriatric Use In clinical trials, 54 patients between the ages of 65 and 75 years, and 11 patients 75 years and over received Articaine HCl and Epinephrine containing epinephrine 1:100,000. Among all patients between 65 and 75 years, doses from 0.43 mg/kg to 4.76 mg/kg (0.9 to 11.9 mL) were administered to 35 patients for simple procedures and doses from 1.05 mg/kg to 4.27 mg/kg (1.3 to 6.8 mL) were administered to 19 patients for complex procedures. Among the 11 patients ≥ 75 years old, doses from 0.78 mg/kg to 4.76 mg/kg (1.3 to 11.9 mL) were administered to 7 patients for simple procedures and doses of 1.12 mg/kg to 2.17 mg/kg (1.3 to 5.1 mL) were administered to 4 patients for complex procedures.
Approximately 6% of patients between the ages of 65 and 75 years and none of the 11 patients 75 years of age or older required additional injections of anesthetic for complete anesthesia compared with 11% of patients between 17 and 65 years old who required additional injections. No overall differences in safety or effectiveness were observed between elderly subjects and younger subjects, and other reported clinical experience has not identified differences in responses between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out.
🆘 Overdosage ▾
10 OVERDOSAGE Acute emergencies from local anesthetics are generally related to high plasma levels encountered during therapeutic use of local anesthetics or to unintended subarachnoid injection of local anesthetic solution [see Warnings and Precautions (5.1 , 5.2) ]. The first consideration is prevention, best accomplished by careful and constant monitoring of cardiovascular and respiratory vital signs and the patient's state of consciousness after each local anesthetic injection. At the first sign of change, oxygen should be administered.
The first step in the management of convulsions, as well as hypo-ventilation, consists of immediate attention to the maintenance of a patent airway and assisted or controlled ventilation as needed. The adequacy of the circulation should be assessed. Should convulsions persist despite adequate respiratory support, treatment with appropriate anticonvulsant therapy is indicated.
The practitioner should be familiar with the use of anticonvulsant drugs, prior to the use of local anesthetics. Supportive treatment of circulatory depression may require administration of intravenous fluids and, when appropriate, a vasopressor. If not treated immediately, both convulsions and cardiovascular depression can result in hypoxia, acidosis, bradycardia, arrhythmias, and/or cardiac arrest.
If cardiac arrest should occur, standard cardiopulmonary resuscitative measures should be instituted. For additional information about overdose treatment, call a poison control center ( 1-800-222-1222 ).
🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Articaine HCl is an amide local anesthetic. Local anesthetics block the generation and conduction of nerve impulses, presumably by increasing the threshold for electrical excitation in the nerve, by slowing the propagation of the nerve impulse, and by reducing the rate of rise of the action potential. In general, the progression of anesthesia is related to the diameter, myelination, and conduction velocity of the affected nerve fibers.
Epinephrine is a vasoconstrictor added to articaine HCl to slow absorption into the general circulation and thus prolong maintenance of an active tissue concentration.
12.2Pharmacodynamics Clinically, the order of loss of nerve function is as follows: (1) pain; (2) temperature; (3) touch; (4) proprioception; and (5) skeletal muscle tone. The onset of anesthesia has been shown to be within 1 to 9 minutes of injection of Articaine HCl and Epinephrine. Complete anesthesia lasts approximately 1 hour for infiltrations and up to approximately 2 hours for nerve block.
Administration of Articaine HCl and Epinephrine results in a 3- to 5-fold increase in plasma epinephrine concentrations compared to baseline; however, in healthy adults it does not appear to be associated with marked increases in blood pressure or heart rate, except in the case of accidental intravascular injection [see Warnings and Precautions (5.1) ].
12.3Pharmacokinetics Absorption: Following dental injection by the submucosal route of an articaine solution containing epinephrine 1:200,000, articaine reaches peak blood concentration about 25 minutes after a single dose injection and 48 minutes after three doses. Peak plasma levels of articaine achieved after 68 and 204 mg doses are 385 and 900 ng/mL, respectively. Following intraoral administration of a near maximum dose of 476 mg, articaine reaches peak blood concentrations of 2037 and 2145 ng/mL for articaine solution containing epinephrine 1:100,000 and 1:200,000, respectively, approximately 22 minutes post-dose.
Distribution: Approximately 60 to 80% of articaine HCl is bound to human serum albumin and γ-globulins at 37°C in vitro . Elimination Metabolism: Articaine HCl is metabolized by plasma carboxyesterase to its primary metabolite, articainic acid, which is inactive. In vitro studies show that the human liver microsome P450 isoenzyme system metabolizes approximately 5% to 10% of available articaine with nearly quantitative conversion to articainic acid.
Excretion: At the dose of 476 mg of articaine, the elimination half-life was 43.8 minutes and 44.4 minutes for articaine solution containing epinephrine 1:100,000 and 1:200,000, respectively. Articaine is excreted primarily through urine with 53-57% of the administered dose eliminated in the first 24 hours following submucosal administration. Articainic acid is the primary metabolite in urine.
A minor metabolite, articainic acid glucuronide, is also excreted in urine. Articaine constitutes only 2% of the total dose excreted in urine.

💬 Information for Patients ▾
17 PATIENT COUNSELING INFORMATION Loss of Sensation and Muscle Function: Inform patients in advance of the possibility of temporary loss of sensation and muscle function following infiltration and nerve block injections [ see Adverse Reactions (6.2) ]. Instruct patients not to eat or drink until normal sensation returns. Methemoglobinemia: Inform patients that use of local anesthetics may cause methemoglobinemia, a serious condition that must be treated promptly.
Advise patients or caregivers to seek immediate medical attention if they or someone in their care experience the following signs or symptoms: pale, gray, or blue colored skin (cyanosis); headache; rapid heart rate; shortness of breath; lightheadedness; or fatigue.
