Lox 10% Spray

Lox 10% Spray is a lidocaine local anesthetic spray used to numb a small area of skin or mucous membranes before or during minor procedures. Each spray delivers lidocaine 10%, a high-strength topical anesthetic that helps reduce pain, burning, or discomfort at the application site. It is commonly used when a doctor needs fast, localized numbness rather than a full-body pain medicine. Lox 10% Spray is supplied by Neon Laboratories in a pack of 10 sprays.

How it works: Lidocaine works by temporarily blocking sodium channels in nerves, which stops pain signals from traveling to the brain. In spray form, Lox 10% Spray coats the target area quickly, helping numb the surface where it is applied.

Lox 10% Spray is a higher-strength lidocaine product, so it is typically chosen when stronger surface numbing is needed and a clinician has decided that this form is appropriate. Compared with lower-strength lidocaine sprays or creams, the 10% spray can provide more intense local anesthesia, but it also requires more careful dosing because too much lidocaine can be harmful.

• Numbing the mouth or throat before minor procedures
• Reducing pain during placement of tubes or instruments
• Local relief for minor surface pain or irritation
• Helping with brief procedures that need topical anesthesia

• Use Lox 10% Spray exactly as directed by your doctor or dentist.
• Shake or prime the spray if your clinician instructs you to do so before the first use.
• Spray only on the exact area that needs numbing; do not use more sprays than prescribed.
• Avoid eating or drinking until the numbness wears off, especially if the mouth or throat was sprayed.
• Do not inhale the spray deeply or spray into the eyes.
• Wash your hands after use unless your hands are the treatment area.

Each spray of Lox 10% Spray contains lidocaine 10%, which is a higher-strength topical dose. The number of sprays and how often it may be used depends on the area being treated, your age, and your doctor’s instructions; there is no one-size-fits-all schedule. Your clinician should set the maximum daily amount, because too much lidocaine can cause serious side effects.

Do not change your dose or stop the medicine without speaking to your doctor.

Common side effects of Lidocaine may include:

• Temporary stinging or burning where sprayed
• Mild numbness or tingling
• Bitter or unpleasant taste if used in the mouth or throat
• Temporary redness or irritation at the application site
• Dizziness or lightheadedness
• Nausea, especially if swallowed or overused

• Lox 10% Spray is a high-strength lidocaine product, so do not use more than prescribed.
• Use extra caution if you have heart disease, liver disease, or a history of seizures.
• Do not spray into the eyes, and avoid using on large or broken skin areas unless your clinician tells you to.
• Numbness in the mouth or throat can make swallowing harder and increase the risk of choking.
• Avoid alcohol and other sedating medicines if they make you feel drowsy or dizzy.
• Do not drive or operate machinery if the spray makes you lightheaded or numbness affects your coordination.
• Tell your doctor if you have had reactions to amide anesthetics or topical numbing medicines before.

• Other lidocaine-containing products, which can raise the total dose
• Antiarrhythmic medicines such as mexiletine, flecainide, or amiodarone
• Medicines that can also lower seizure threshold
• Heavy alcohol use, which may worsen dizziness or toxicity risk

Store Lox 10% Spray at room temperature, away from heat, flames, and direct sunlight, and keep the bottle tightly closed out of reach of children.
