Lidocaine Hydrochloride 2% Topical Solution (Viscous) (Rx)

Lidocaine Oral Solution is a prescription-strength, topical anesthetic in liquid form designed to rapidly numb mouth and throat pain. It’s primarily used to relieve discomfort from mouth ulcers, canker sores, toothaches, sore throat, minor oral surgeries, and irritation from braces or dentures.

No. In most countries, oral lidocaine solutions are available by prescription only due to dosing safety and potential risks if misused. Only lower-concentration oral pain gels or benzocaine products are sometimes OTC.

Topical oral lidocaine may be used in pregnancy if medically necessary and prescribed by your provider. Always consult your doctor for the safest treatment during pregnancy.

Diarrhea is rare but possible, usually if swallowed in large quantities. More common side effects are mild numbness, altered taste, or minor irritation.

Lidocaine does not heal illness or tissue—it is an anesthetic. It numbs pain so you can eat, drink, and speak comfortably while your body heals naturally or treatment is ongoing.

Do not intentionally swallow large amounts. Lidocaine oral solution is meant for swish and spit, or light swallowing only if specifically instructed by your provider (sometimes in cases like esophageal pain). Swallowing small residual amounts is generally considered safe at prescribed doses.

Benzocaine (lower strength, also OTC) Dyclonine Magic mouthwash (custom-blended mouth rinse containing lidocaine, antacids, antihistamines, etc.)

Pain relief begins in 1–5 minutes, with effects lasting 15–45 minutes per dose.

Mild: Temporary numbness, tingling, altered taste, minor irritation Severe/rare: Allergic reaction (rash, swelling), dizziness, irregular heartbeat (usually with overdose), drowsiness, confusion, or seizures if misused

No, lidocaine is not addictive, nor does it produce “highs” or cause substance dependence.

Swallowing small recommended doses as instructed is generally safe. Intentional or accidental ingestion of large amounts can be dangerous and lead to toxicity—seek medical help if you feel chest pain, confusion, severe drowsiness, or irregular heartbeat.

At high doses or with misuse, lidocaine can affect heart rhythm and potentially cause arrhythmias. Therapeutic, topical use in the mouth is very safe under professional guidance.

Lidocaine is metabolized within 2–6 hours. Effects fade much faster, but trace drug may remain until processed by your liver.

Rapid onset—numbing typically begins in 1 to 5 minutes after application.

For most topical oral pain, lidocaine is the gold standard due to its rapid and profound numbing effects. Benzocaine is a common alternative, but often less potent. Magic mouthwash is superior for severe oral mucositis but contains lidocaine as a key ingredient.

Always follow dosing instructions. Maximum safe oral topical dose varies, but using more than prescribed or frequent swallowing increases risk of toxicity. If you are unsure, ask your pharmacist or healthcare provider.

No. Both are local anesthetics, but lidocaine is prescription-only and generally longer acting, while benzocaine is OTC, weaker, and more suitable for minor pain.

Usually every 3–4 hours as needed. Do NOT exceed prescribed frequency or total daily dose.

People allergic to lidocaine or other amide-type anesthetics. Infants (risk of methemoglobinemia with all topical anesthetics). Anyone with severe liver/kidney issues, certain heart rhythms, or on interacting medications—ask your doctor.

Lidocaine just numbs pain—it does not heal. It provides comfort while allowing you to eat, drink, and recover as the underlying condition improves.
