🎯What it's used for▾
Lidocaine is a local anesthetic available in many forms, each approved for specific uses.
- Temporary relief of pain, itching, and burning from minor burns, sunburn, cuts, scrapes, insect bites, and minor skin irritations (topical creams, gels, patches, and sprays)
- Relief of discomfort, itching, and pain from hemorrhoids, anal fissures, pruritus ani, pruritus vulvae, and related conditions of the skin and mucous membranes (Lidocaine Hydrochloride cream)
- Temporary relief of muscle soreness and minor joint pain in the back, knees, wrists, neck, hips, shoulders, and elbows (Lidocaine Pain Relief Gel-Patch)
- Temporary male genital desensitization to help slow ejaculation and reduce oversensitivity (Dynamo Delay, Dynamo Delay Sample Bottle sprays; INTIMALE Maximum Strength Delay and SKINS DELAY Maximum Strength Lidocaine topical solutions)
- Local and regional anesthesia during medical procedures, including infiltration, nerve blocks (such as brachial plexus and intercostal blocks), and epidural blocks (Accucaine and Xylocaine injections — administered only by trained clinicians)
⚙️How it works▾
Lidocaine works by blocking the nerve signals that cause pain. It stabilizes the nerve cell membrane by preventing sodium ions from flowing into the nerve cell — and without that flow, the nerve can't fire or send a pain signal. The result is temporary numbness or reduced sensation in the treated area.
When lidocaine reaches high blood levels (which is a risk mainly with injections or misuse of topical products), it can also affect the heart and central nervous system, which is why injectable forms require careful medical supervision.
💊How it's taken▾
How you take lidocaine depends on the product and its intended use.
- Skin patches: Apply to clean, dry skin. Most brands are used up to 3–4 times daily; some allow up to 12 hours of wear per patch. Follow the specific product's label for patch duration and how many patches per day.
- Creams and gels: Apply a thin layer to the affected area, typically every 6–8 hours, no more than 3–4 times per day. Wash hands after applying.
- Topical sprays: Spray onto the affected skin 2–4 times daily depending on the product. Some delay sprays require application a few minutes before intercourse.
- Injections: Only administered by a trained healthcare provider. The dose, volume, and technique are determined by the type of procedure and the patient's condition.
Always follow your product's label or your prescriber's instructions. Do not use more than directed.
🤒Side effects — in detail▾
Topical lidocaine products are generally well tolerated, but some people experience skin reactions at the application site.
- Redness, irritation, or itching where applied
- Skin rash or blistering
- Swelling or pain at the site
- Burning or stinging sensation
Stop use and contact your doctor if skin reactions worsen, blistering develops, or symptoms don't improve after 7 days. With injections, serious side effects including seizures, irregular heartbeat, and loss of consciousness can occur if too much drug enters the bloodstream — these require emergency medical care immediately.
⚠️Warnings & precautions▾
- Methemoglobinemia (blood oxygen problem): All local anesthetics can rarely cause this dangerous condition, where the blood loses its ability to carry oxygen properly. Signs include bluish or grayish skin color. People with G6PD deficiency, heart or lung problems, and infants under 6 months are at highest risk. Get emergency help immediately if this is suspected.
- High blood levels and toxicity: Too much lidocaine absorbed into the bloodstream — especially with injections — can cause seizures, dangerously slow or irregular heart rhythms, and cardiac arrest. Injectable lidocaine must only be given by trained clinicians with emergency equipment on hand.
- Heating pads and skin patches: Applying heat over a lidocaine patch significantly increases the amount absorbed into your body. Never use a heating pad on or near a lidocaine patch.
- Used patch safety: Used patches still contain active lidocaine. Dispose of them by folding the sticky sides together and keep them away from children and pets — swallowing a patch can cause serious harm.
- Do not use on damaged skin: Avoid applying to open wounds, puncture wounds, or inflamed or blistered skin unless a doctor directs you to.
- Allergic reactions: Serious allergic reactions, including anaphylaxis, can occur. Stop use and get emergency help if you have trouble breathing, swelling, or severe rash.
🔀What it interacts with▾
Lidocaine can interact with other substances — here's what to be aware of:
- Other topical anesthetics: Using multiple lidocaine-containing products or other local anesthetic products at the same time increases the total amount absorbed — this raises the risk of side effects. Tell your provider about every product you're using.
- Heat sources: Applying a heating pad over a lidocaine skin patch sharply increases drug absorption into the bloodstream, raising the risk of toxicity.
- Oxidizing agents and certain medications: Some drugs that act as oxidizing agents can increase the risk of methemoglobinemia when used with local anesthetics. Ask your pharmacist or doctor about any medications you take.
This is not a complete list of interactions. Always talk with your doctor or pharmacist before starting, stopping, or changing any medication.
📋Before taking it▾
- Pregnancy or breastfeeding: Ask a health professional before using any lidocaine product. Lidocaine can cross the placental barrier.
- Children: Most topical products are not recommended for children under 12 without a doctor's guidance; some products specify age 2 or 4 as the minimum. Always check the label for the specific product.
- G6PD deficiency (a genetic enzyme deficiency): Higher risk of methemoglobinemia — tell your doctor before using.
- Heart or lung conditions: May increase risk of serious effects if significant lidocaine is absorbed — discuss with your provider.
- Liver disease: Lidocaine is metabolized by the liver; reduced liver function slows processing and can lead to higher drug levels in the body.
- Allergy to local anesthetics: Do not use if you've had an allergic reaction to lidocaine or similar anesthetics before.
- Infants under 6 months: At higher risk of methemoglobinemia; use only under close medical supervision.
🚑If you take too much▾
Serious problems from lidocaine are most often related to high levels in the bloodstream — from too much absorbed through the skin, or from an injection reaching a blood vessel. Signs include seizures, loss of consciousness, very slow or irregular heartbeat, and difficulty breathing. If any of these occur, seek emergency medical care immediately. Poison Control should be contacted right away if a child or pet swallows a lidocaine patch.
📡Pharmacodynamics — effects in the body▾
At normal doses, lidocaine blocks nerve impulses in the treated area, producing localized numbness without affecting the whole body. If blood levels become excessively high, lidocaine can affect the heart — causing changes in cardiac output and blood pressure, and potentially dangerous heart rhythm problems. These cardiovascular effects are the primary concern with injectable forms and with misuse of topical products.
🔬Pharmacokinetics — how your body processes it▾
With topical skin patches, the amount absorbed into the body depends on how long the patch is worn and how large an area it covers. Applying heat increases absorption significantly. Lidocaine is processed quickly by the liver into metabolites that have mild anesthetic activity of their own, and both the drug and its metabolites are cleared by the kidneys. After an intravenous dose, the half-life (the time it takes the body to clear half the drug) is roughly 1.5 to 2.5 hours; liver problems can extend this significantly. Less than 10% of the drug leaves the body unchanged in urine.
📦How to store it▾
Store at 20° to 25°C (68° to 77°F); excursions permitted between 15° to 30°C (59° to 86°F) .

Shares are of the Medicaid prescriptions shown here. Product grouping follows RxNorm (the National Library of Medicine’s drug terminology), so “one product” means one strength & dosage form regardless of manufacturer. Dollar figures are gross Medicaid reimbursement before mandatory rebates — rebates (often large, especially for brand-name drugs) are confidential, so actual net cost to Medicaid is lower than shown.

📈 What people report — real-world data (FDA FAERS)
After a medicine reaches the market, patients, doctors and drugmakers can send the FDA reports of problems they think may be linked to it. Here’s what’s been reported for Lidocaine — a signal of what to watch for, not proof the drug caused it.
Source: openFDA, from the FDA Adverse Event Reporting System (FAERS). These are voluntary reports — they don’t prove the drug caused the effect, and counts reflect how often something was reported, not how often it actually happens. Reports also often name the very problem the medicine is taken for — a common reason to file one is that the drug didn’t help — so for a pain reliever you may see “pain” high on the list; that points to why the report was filed, not to the drug causing the symptom. This counts every report that lists Lidocaine in any role, so the total runs higher than the FDA’s official dashboard, which counts only cases where the drug is the suspect. For the authoritative figures, see the FDA FAERS Public Dashboard. Always talk to your pharmacist or doctor.
🏛️ The road to your pharmacy
How Lidocaine went from FDA review to the pharmacy shelf — the key milestones in its regulatory journey.

🚨 Recall history
A recall is when a specific batch of a medicine is pulled from the market — usually a manufacturing issue, not a problem with the drug itself. Class I is most serious, Class III least.

🔬 Where this comes from
Core label, product, RxNorm, safety, and utilization data on this page come from the sources identified below. AI-written, editorial, and licensed sections are labeled separately.
How we combine label and product data
HelloPharmacist combines public FDA and NLM records; we don’t author the underlying clinical facts. We identified 1,022 FDA-filed SPL label sets within the page’s selected clinical scope after exact ingredient or ingredient-combination matching and applicable route/form matching. The representative label is the starting point for the displayed reference monograph; the 12 largest stored in-scope SPL records, which may include that representative, are compared section by section, and the longest available version of each section is retained. Forms, routes, brands, labelers, product-listed strengths, and product-record counts are aggregated separately from ingredient-matched FDA NDC Directory records; package records listed above are associated with the linked SPL; and the normalized concept hierarchy comes from NLM RxNorm.
For canonical ingredient pages, bounded product-attributed indication and administration excerpts may be added to the AI evidence, and the generator is instructed to preserve available product, brand, route, and form qualifiers instead of treating one label as universal. Where a section is identified as AI-written, its plain-language text is generated from bounded label evidence. New draft drug pages remain in the admin review queue before first publication. Scilex Pharmaceuticals Inc. is the representative DailyMed label linked for verification and dates; it is not the sole source used for the page.
This is general education, not medical advice — always consult your doctor or pharmacist about your medications and any medical condition. For the exact wording of the linked representative label, view that label on DailyMed; some displayed composite sections may come from other in-scope SPL labels.
