⏳ Availability & generic status
We did not find an FDA-approved generic match for this exact strength, form and route. Patent/protection dates below may affect future generic timing.
Why the date isn’t exact: Generic timing can change because patents may be challenged, settled, licensed, added, removed, or worked around with a narrower label — and FDA approval does not always mean a pharmacy can get the generic today.
🛈 What do these terms mean?
- Patent
- Legal protection listed in the Orange Book that may delay generic approval or launch. Issued by the U.S. Patent & Trademark Office.
- Substance patent
- Covers the active drug molecule itself — the hardest to design around. A generic generally can’t launch until it expires.
- Formulation (product) patent
- Covers a specific formulation or dosage form. A generic can sometimes work around it with a different formulation.
- Method-of-use patent
- A patent covering one specific approved use of the drug — not necessarily the whole molecule. A generic can sometimes launch with a “skinny label” that carves out the protected use and keeps the others.
- Skinny label
- A generic label that omits a still-patented use when the FDA allows it — letting a generic reach the market for the unprotected uses.
- Exclusivity
- FDA-granted marketing protection, separate from patents — e.g. 5-yr new chemical entity, 7-yr orphan drug, or a +6-month pediatric extension.
- Paragraph IV
- A generic applicant’s formal challenge to a listed patent. It can potentially lead to earlier generic entry, but often involves litigation or a settlement.
- RLD / RS
- Reference Listed Drug — the brand product the FDA uses as the reference for generic applications. Reference Standard — the product the FDA expects generics to compare against in bioequivalence testing.
- TE / AB rating
- FDA therapeutic-equivalence rating. An AB rating generally means the FDA considers a generic therapeutically equivalent to — and substitutable for — the brand.
- LOE (loss of exclusivity)
- The latest patent or exclusivity currently listed — the loss-of-exclusivity / latest-listed-protection date shown on this page. Paragraph-IV challenges and settlements can move the real date earlier; FDA approval and a manufacturer’s decision to market can move it later.
Built from the FDA Orange Book. The bars above are scaled to each protection’s expiry; the red LOE marker is the last one to lapse.

📄 Full prescribing information FDA SPL
🎯 Indications and Usage ▾
1 INDICATIONS AND USAGE PLIAGLIS is indicated for use on intact skin in adults to provide topical local analgesia for superficial dermatological procedures such as dermal filler injection, pulsed dye laser therapy, facial laser resurfacing, and laser-assisted tattoo removal. PLIAGLIS is a combination of lidocaine, an amide local anesthetic, and tetracaine, an ester local anesthetic, indicated for use on intact skin in adults to provide topical local analgesia for superficial dermatological procedures such as dermal filler injection, pulsed dye laser therapy, facial laser resurfacing, and laser-assisted tattoo removal.
( 1 )
⏱️ Dosage and Administration ▾
2 DOSAGE AND ADMINISTRATION Apply only to intact skin. ( 2.1 ) Do not exceed the recommended dose of drug or duration of application. ( 2.1 ) Recommended duration of application ( 2.2 ): For dermal filler injection ablative laser facial resurfacing, or pulsed-dye laser therapy 20-30 minutes prior to procedure For superficial dermatological procedures such as laserassisted tattoo removal 60 minutes prior to procedure See Full Prescribing Information for amount to apply based upon treatment site surface area.
( 2.3 )
2.1Important Dosage and Administration Instructions For use in adults only. PLIAGLIS should only be applied to intact skin. PLIAGLIS should not be applied to a procedure site after the procedure has been performed.
Remove PLIAGLIS if skin irritation or a burning sensation occurs during application. In order to minimize the risk of systemic toxicity, do not exceed the recommended amount of drug to apply or the duration of the application [see Overdosage (10) ] . Avoid eye and lip contact with PLIAGLIS.
Wash hands after handling PLIAGLIS. Upon removal from the treatment site, discard the used PLIAGLIS in a location that is out of the reach of children and pets. Access to PLIAGLIS by children or pets should be prevented during usage and storage of the product [see Warnings and Precautions (5.2) ] .
Use only as directed.
2.2Recommended Dosing Duration For superficial dermatological procedures, such as dermal filler injection, non-ablative laser facial resurfacing, or pulsed-dye laser therapy, apply PLIAGLIS to intact skin for 20 to 30 minutes prior to the procedure. See Table 1 for instructions on the amount to apply. For superficial dermatological procedures, such as laser-assisted tattoo removal, apply PLIAGLIS to intact skin for 60 minutes prior to the procedure.
See Table 1 for instructions on the amount to apply.
2.3Recommended Dosage The dose of PLIAGLIS that provides effective local dermal analgesia depends on the duration of the application. Although not specifically studied, a shorter duration of application may result in a less complete dermal analgesia or a shorter duration of adequate dermal analgesia. Determine the amount of drug to apply The amount (length) of PLIAGLIS that should be dispensed is determined by the size of the area to be treated (see Table 1 ).
Using the ruler on the applicator included in the carton, squeeze out and measure the amount of PLIAGLIS that approximates the amount required to achieve proper coverage. Spread PLIAGLIS evenly and thinly (approximately 1 mm or the thickness of a dime) across the treatment area using a flat-surfaced tool such as a metal spatula or tongue depressor. After waiting the required application time, remove the PLIAGLIS by grasping a free-edge with your fingers and pulling it away from the skin.

⛔ Contraindications ▾
4 CONTRAINDICATIONS PLIAGLIS is contraindicated in patients with a known history of sensitivity to lidocaine or tetracaine, local anesthetics of the amide or ester type, or to any other component of the product [ see Warnings and Precautions (5.4) ]. PLIAGLIS is contraindicated in patients with para-aminobenzoic acid (PABA) hypersensitivity. Known history of sensitivity to lidocaine or tetracaine, or local anesthetics of the amide or ester type.
( 4 ) Para-aminobenzoic acid (PABA) hypersensitivity. ( 4 )
⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Methemoglobinemia : Cases of methemoglobinemia have been reported in association with local anesthetic use. ( 5.1 ) Overexposure : To avoid overexposure that could lead to adverse effects, do not use for longer duration or over larger surface areas than recommended. ( 5.2 ) consider total amount of local anesthetics absorbed from all formulations.
( 5.2 ) do not apply to mucous membranes or broken or inflamed skin. ( 5.2 ) use with caution in patients who may be more sensitive to systemic effects of PLIAGLIS, including acutely ill or debilitated or those with severe hepatic disease or pseudocholinesterase deficiency. ( 5.2 ) Risk of Secondary Exposure to Children and Pets : Store and dispose of PLIAGLIS out of reach of children and pets due to the risk of accidental exposure and resulting toxicity.
( 5 ) Anaphylactic Reactions : Seek emergency help if an anaphylactic reaction occurs. ( 5.4 ) Eye Irritation : Avoid contact with eyes. ( 5.5 )
5.1Methemoglobinemia Cases of methemoglobinemia have been reported in association with local anesthetic use. Although all patients are at risk for methemoglobinemia, patients with glucose-6-phosphate dehydrogenase deficiency, congenital or idiopathic methemoglobinemia, cardiac or pulmonary compromise, infants under 6 months of age, and concurrent exposure to oxidizing agents or their metabolites are more susceptible to developing clinical manifestations of the condition. If local anesthetics must be used in these patients, close monitoring for symptoms and signs of methemoglobinemia is recommended.
Signs of methemoglobinemia may occur immediately or may be delayed some hours after exposure, and are characterized by a cyanotic skin discoloration and/or abnormal coloration of the blood. Methemoglobin levels may continue to rise; therefore, immediate treatment is required to avert more serious central nervous system and cardiovascular adverse effects, including seizures, coma, arrhythmias, and death. Discontinue PLIAGLIS and any other oxidizing agents.
Depending on the severity of the signs and symptoms, patients may respond to supportive care, i.e., oxygen therapy, hydration. A more severe clinical presentation may require treatment with methylene blue, exchange transfusion, or hyperbaric oxygen.
5.2Overexposure Application of PLIAGLIS for longer times than those recommended or application of PLIAGLIS over larger surface areas than those recommended could result in absorption of lidocaine and tetracaine at doses that could lead to serious adverse effects [see Overdosage (10) ] . When PLIAGLIS is used concomitantly with other products containing local anesthetic agents, consider the amount absorbed from all formulations since the systemic toxic effects are thought to be additive and potentially synergistic with lidocaine and tetracaine.
PLIAGLIS is not recommended for use on mucous membranes or on areas with a compromised skin barrier because these uses have not been adequately studied. Application to broken or inflamed skin may result in toxic blood concentrations of lidocaine and tetracaine from increased absorption. Use PLIAGLIS with caution in patients who may be more sensitive to the systemic effects of lidocaine and tetracaine, including the acutely ill or debilitated.
Patients with severe hepatic disease or pseudocholinesterase deficiency, because of their inability to metabolize local anesthetics normally, are at a greater risk of developing toxic plasma concentrations of lidocaine and tetracaine.
5.3Risks of Secondary Exposure to Children and Pets Used PLIAGLIS contains a large amount of lidocaine and tetracaine. The potential exists for a small child or pet to suffer serious adverse effects from ingesting PLIAGLIS, although this risk with PLIAGLIS has not been evaluated. After use, replace the cap securely on the tube. It is important to store and dispose of PLIAGLIS out of the reach of children and pets.

🤒 Adverse Reactions ▾
6 ADVERSE REACTIONS The following adverse reactions are described elsewhere in the labeling: Methemoglobinemia [see Warnings and Precautions (5.1) ] Overexposure [see Warnings and Precautions (5.2) ] Risks of Secondary Exposure in Children and Pets [see Warnings and Precautions (5.3) ] Anaphylactic Reactions [see Warnings and Precautions (5.4) ] Eye Irritation [see Warnings and Precautions (5.5) ] Most common local reactions were erythema (47%), skin discoloration (16%), and edema (14%). ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact IPG Pharmaceuticals, Inc. at 1-888-711-7116 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.
6.1Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. However, the adverse reaction information from clinical trials does provide a basis for identifying the adverse events that appear to be related to drug use and for approximating their incidence in clinical practice. PLIAGLIS has been evaluated for safety in 2159 persons undergoing a superficial dermal procedure.
PLIAGLIS was studied in 11 placebo-controlled and 1 active-controlled trials, and in open-label safety trials. All 2159 persons were exposed to only a single application of PLIAGLIS. Adverse reactions were assessed by collecting spontaneously reported adverse reactions, and observations made on formal evaluation of the skin for specific reactions.
Most common adverse reactions in clinical trials Localized Reactions: In clinical studies, the most common local reactions were erythema (47%), skin discoloration (e.g., blanching, ecchymosis, and purpura) (16%), and edema (14%). There were no serious adverse reactions. However, one patient withdrew due to burning pain at the treatment site.
Other Localized Reactions: The following dermal adverse reactions occurred in 1% or less of PLIAGLIS-treated patients: ecchymosis, petechial rash, vesiculobullous rash, perifollicular erythema, perifollicular edema, pruritus, rash, maculopapular rash, dry skin, contact dermatitis, and acne. Systemic (Dose-Related) Reactions: Across all trials, 19 subjects experienced a systemic adverse reaction, 15 of whom were treated with PLIAGLIS and 4 with placebo. The frequency of systemic adverse reactions was greater for the PLIAGLIS group (1%) than the placebo group (0.3%).
The most common systemic adverse events were headache, vomiting, dizziness, and fever, all of which occurred with a frequency of <1%. Other systemic reactions were syncope, nausea, confusion, dehydration, hyperventilation, hypotension, nervousness, paresthesia, pharyngitis, stupor, pallor, and sweating. Systemic adverse reactions of lidocaine and tetracaine are similar in nature to those observed with other amide and ester local anesthetic agents, including CNS excitation and/or depression (lightheadedness, nervousness, apprehension, euphoria, confusion, dizziness, drowsiness, tinnitus, blurred or double vision, vomiting, sensation 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. Signs of CNS toxicity may start at plasma concentrations of lidocaine at 1000 ng/mL. The plasma concentrations at which tetracaine toxicity may occur are less well characterized; however, systemic toxicity with tetracaine is thought to occur with much lower plasma concentrations compared with lidocaine.
The toxicity of co-administered local anesthetics is thought to be at least additive. Cardiovascular manifestations may include bradycardia, hypotension and cardiovascular collapse leading to arrest.
6.2 Postmarketing Experience The following adverse reactions have been identified d…
🔄 Drug Interactions ▾
7 DRUG INTERACTIONS Antiarrhythmic Drugs : Use with caution in patients receiving Class I antiarrhythmic drugs (such as tocainide and mexiletine) because the systemic toxic effects are thought to be additive and potentially synergistic with lidocaine and tetracaine. ( 7.1 )
7.1Antiarrhythmic Drugs PLIAGLIS should be used with caution in patients receiving Class I antiarrhythmic drugs (such as tocainide and mexiletine) since the systemic toxic effects are thought to be additive and potentially synergistic with lidocaine and tetracaine.
7.2Local Anesthetics When PLIAGLIS is used concomitantly with other products containing local anesthetic agents, the amount absorbed from all formulations should be considered since the systemic toxic effects are thought to be additive and potentially synergistic with lidocaine and tetracaine.
7.3Drugs That May Cause Methemoglobinemia When Used with PLIAGLIS 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: 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
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS
8.1Pregnancy Risk Summary There are no available data on PLIAGLIS use in pregnant women to determine a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. Available data from an epidemiologic study and case series with parenteral lidocaine use in pregnant women have not identified a drug-associated risk of major birth defects, miscarriage or other adverse maternal or fetal outcomes. Published data on tetracaine use in pregnant women are not sufficient to determine any drug-associated risks.
The amount of lidocaine and tetracaine systemically absorbed from PLIAGLIS is low compared to the parenteral route of administration and is not expected to result in significant fetal exposure. Systemic exposure of PLIAGLIS is directly related to both the duration of application and the surface area over which it is applied [ see Clinical Pharmacology (12.3) ] . In a published animal reproduction study, pregnant rats administered lidocaine by continuous subcutaneous infusion at doses approximately 1.3 times the maximum recommended human dose (MRHD) of 53 grams of PLIAGLIS during the period of organogenesis resulted in lower fetal body weights.
In a published animal reproduction study, pregnant rats administered lidocaine, containing 1:100,000 epinephrine, injected into the masseter muscle of the jaw or into the gum of the lower jaw on Gestation Day 11 at 0.02 times the MRHD of PLIAGLIS resulted in developmental delays in neonates. Subcutaneous administration of tetracaine to pregnant rats and rabbits during organogenesis did not produce adverse embryofetal effects at 0.03 times the MRHD of PLIAGLIS (see Data ) . The estimated background risk of major birth defects and miscarriage for the indicated population is unknown.
All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. Data Animal Data Lidocaine administered by subcutaneous injection to pregnant rats during organogenesis was not teratogenic at doses up to 60 mg/kg (0.16 times the level of lidocaine contained in the MRHD of 53 grams of PLIAGLIS based on a mg/m 2 body surface area (BSA) comparison).
Lidocaine administered by subcutaneous injection to pregnant rabbits during organogenesis was not teratogenic at doses up to 15 mg/kg (0.08 times the level of lidocaine in the MRHD of PLIAGLIS on a mg/m 2 basis). In a published study, lidocaine administered to pregnant rats by continuous subcutaneous infusion during the period of organogenesis at 100, 250, and 500 mg/kg/day, did not produce any structural abnormalities, but did result in lower fetal weights at 500 mg/kg/day dose (approximately 1.3 times the level of lidocaine in the MRHD of PLIAGLIS on a mg/m 2 basis) in the absence of maternal toxicity.
Tetracaine administered by subcutaneous injection to pregnant rats during organogenesis was not teratogenic at doses up to 10 mg/kg or in rabbits at doses up to 5 mg/kg (equivalent to 0.03 times of tetracaine in the MRHD of PLIAGLIS on a mg/m 2 basis). Lidocaine and tetracaine administered by subcutaneous injection to pregnant rats during organogenesis as a 1:1 eutectic mixture of 10 mg/kg each (equivalent to 0.03 times the active components in the MRHD of PLIAGLIS on a mg/m 2 basis) was not teratogenic. Lidocaine and tetracaine by subcutaneous injection to pregnant rabbits during organogenesis as a 1:1 eutectic mixture of 5 mg/kg each was not teratogenic in rabbits (equivalent to 0.03 times the active components in the MRHD of PLIAGLIS on a mg/m 2 basis).

🧒 Pediatric Use ▾
8.4Pediatric Use Safety and effectiveness of PLIAGLIS in pediatric patients have not been established. Unintended exposure in pediatric patients could possibly lead to serious adverse effects [see Warnings and Precautions (5.2) ] . In a trial of PLIAGLIS in pediatric patients aged 5 to 17 years undergoing venipuncture (blood draw or intravenous line placement), PLIAGLIS applied for 30 minutes failed to show efficacy over placebo in reducing the pain associated with the procedure.
🧓 Geriatric Use ▾
8.5Geriatric Use Of the total number of subjects treated with PLIAGLIS in controlled clinical studies, 161 subjects were 65 years and older, while 50 subjects were over 75 years of age. No overall differences in safety and effectiveness were observed between these subjects and younger subjects. However, increased sensitivity in individual patients aged 65 years and older cannot be ruled out [see Clinical Pharmacology (12.3) ] .
🆘 Overdosage ▾
10 OVERDOSAGE Application of 59 g of PLIAGLIS over 400 cm 2 (62 inch 2 ) for up to 120 minutes to adults produces peak plasma concentrations of lidocaine of 220 ng/mL. Toxic levels of lidocaine (>5000 ng/mL) cause CNS toxicity, including the risk of seizure. Signs of CNS toxicity may start at plasma concentrations of lidocaine as low as 1000 ng/mL, and the risk of seizures generally increases with increasing plasma levels.
Very high levels of lidocaine can cause respiratory arrest, coma, decreases in cardiac output, total peripheral resistance and mean arterial pressure, ventricular arrhythmias and cardiac arrest. Tetracaine is associated with a profile of systemic CNS and cardiovascular adverse events similar to lidocaine, although toxicity associated with tetracaine is thought to occur at lower doses compared to lidocaine. The toxicity of co-administered local anesthetics is thought to be at least additive.
In the absence of massive topical overdose or oral ingestion, other etiologies for the clinical effects or overdosage from other sources of lidocaine, tetracaine or other local anesthetics should be considered. The management of overdosage includes close monitoring, supportive care and symptomatic treatment. Dialysis is of negligible value in the treatment of acute overdosage of lidocaine or tetracaine.

12.1Mechanism of Action Lidocaine is an amide-type local anesthetic agent and tetracaine is an ester-type local anesthetic agent. Both lidocaine and tetracaine block sodium ion channels required for the initiation and conduction of neuronal impulses which, in certain instances, results in local anesthesia. When applied to intact skin, PLIAGLIS provides local dermal analgesia by the release of lidocaine and tetracaine from the peel into the skin.
12.2Pharmacodynamics Duration of analgesia was evaluated using a pinprick test in 40 adult volunteers. The median duration of analgesia was 11 hours. There was no difference between the 30-minute and 60-minute PLIAGLIS application periods with respect to the mean for time to return of sensation. However, 55% of PLIAGLIS treated subjects still reported diminished sensation at the end of the 13-hour study period.
12.3Pharmacokinetics Absorption: The amount of lidocaine and tetracaine systemically absorbed from PLIAGLIS is directly related to both the duration of application and the surface area over which it is applied, Table 2. Application of 59 g of PLIAGLIS over 400 cm 2 (62 inch 2 ) for up to 120 minutes to adults produces peak plasma concentrations of lidocaine of 220 ng/mL. Tetracaine plasma levels were not measurable (<0.9 ng/mL).
Systemic exposure to lidocaine, as measured by C max and AUC 0-24 , was proportional to the application area, and increased with application time up to 60 minutes. Table 2.

2.8Tetracaine, 2.3 <0.9 na 31 400 ≤ 65 6 60 Lidocaine, 2.2 48
3.8Tetracaine, 2.2 <0.9 na Distribution: When lidocaine is administered intravenously to healthy volunteers, the steady-state volume of distribution is approximately 0.8 to
1.3L/kg. At lidocaine concentrations observed following the recommended product application, approximately 75% of lidocaine is bound to plasma proteins, primarily alpha-1-acid glycoprotein. At much higher plasma concentrations (1 to 4 mg/mL of free base) the plasma protein binding of lidocaine is concentration dependent.
Lidocaine crosses the placental and blood brain barriers, presumably by passive diffusion. CNS toxicity may typically be observed around 5000 ng/mL of lidocaine; however, a small number of patients reportedly may show signs of toxicity at approximately 1000 ng/mL [see Overdosage (10) ] . Volume of distribution and protein binding have not been determined for tetracaine due to rapid hydrolysis in plasma.
Metabolism: It is not known if lidocaine or tetracaine is metabolized in the skin. Lidocaine is metabolized rapidly by the liver to a number of metabolites, including monoethylglycinexylidide (MEGX) and glycinexylidide (GX), both of which have pharmacologic activity similar to, but less potent than that of lidocaine. The major metabolic pathway of lidocaine, sequential N-deethylation to MEGX and GX, is primarily mediated by CYP1A2 with a minor role of CYP3A4.
The metabolite, 2,6- xylidine, has unknown pharmacologic activity. Following intravenous administration of lidocaine, MEGX and GX concentrations in serum range from 11% to 36% and from 5% to 11% of lidocaine concentrations, respectively. Serum concentrations of MEGX were about one-third the serum lidocaine concentrations.
Tetracaine undergoes rapid hydrolysis by plasma esterases. Primary metabolites of tetracaine include para-aminobenzoic acid and diethylaminoethanol, both of which have an unspecified activity. Elimination: The half-life of lidocaine elimination from the plasma following intravenous administration is approximately 1.8 hr.
Lidocaine and its metabolites are excreted by the kidneys. More than 98%…

📋 Description ▾
11 DESCRIPTION PLIAGLIS (lidocaine and tetracaine) Cream 7% / 7% is a topical local anesthetic cream that forms a pliable peel on the skin when exposed to air. The drug formulation is an emulsion in which the oil phase is a 1:1 eutectic mixture of lidocaine 7% and tetracaine 7%. The eutectic mixture has a melting point below room temperature and therefore both local anesthetics exist as a liquid oil rather than as crystals.
The net weight of lidocaine is 2.1 g and of tetracaine is 2.1 g per 30 g tube. Lidocaine, an amide local anesthetic, is chemically designated as acetamide,2-(diethylamino)-N-(2,6-dimethylphenyl) and has an octanol: water partition ratio of 182 at pH 7.3. The molecular weight of lidocaine is 234.3, and the molecular formula is C14H22N2O.
The structural formula is: Tetracaine, an ester local anesthetic, is chemically designated as 2-dimethylaminoethyl 4-n-butyl-aminobenzoate and has an octanol:water partition ratio of 5370 at pH 7.3. The molecular weight of tetracaine is 264.4, and the molecular formula is C15H24N2O2. The structural formula is: Each gram of PLIAGLIS contains lidocaine 70 mg and tetracaine 70 mg in a 1:1 eutectic mixture and it also contains the following inactive ingredients: anhydrous dibasic calcium phosphate, methylparaben, polyvinyl alcohol, propylparaben, purified water, sorbitan monopalmitate, and white petrolatum. image description image description
💬 Information for Patients ▾
17 PATIENT COUNSELING INFORMATION Prior to treatment, advise patient of the following: Inform patients that use of local anesthetics may cause methemoglobinemia, a serious condition that must be treated promptly. Advise patients or caregivers to stop use and 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. Advise patients to inform the healthcare provider if they experience skin irritation or a burning sensation because the product will need to be immediately removed [see Dosage and Administration (2.1)].
Advise patients of the signs and symptoms of hypersensitivity reactions and to seek immediate medical attention should they occur [see Warnings and Precautions (5.4)]. Advise patients that PLIAGLIS may lead to diminished or blocked sensation in the treated skin and to avoid inadvertent trauma through rubbing, scratching, or exposure to heat or cold before complete sensation occurs. Advise breastfeeding women not to apply PLIAGLIS directly to the nipple and areola to avoid direct infant exposure [see Use in Specific Populations (8.2)].
