Lidocaine Viscous 2% Oral Solution by Himka (Rx)

Lidocaine viscous 2% (oral solution) is a prescription topical anesthetic (numbing agent) for the mouth and throat. It’s basically lidocaine hydrochloride at 2% concentration (20 mg per mL) in a thick, flavored liquid (often banana‐flavored). This viscous solution is used only by mouth (swished, gargled, or applied to the gums or sore areas). Its main use is to temporarily numb (“anesthetize”) irritated or inflamed mucous membranes in the mouth and pharynx. For example, it helps relieve pain from canker sores (aphthous ulcers), stomatitis, sore gums, or a sore throat, and it’s often used to suppress the gag reflex during dental or medical procedures.

Because lidocaine is a potent anesthetic, this medication must be used exactly as prescribed. Typical directions are to dose a specific small volume (often using a dosing syringe or cup), swish it in the mouth for a short time (for example 1–2 minutes), and then spit out the excess (any small swallowed amount in adults is usually absorbed and metabolized, but large ingestions must be avoided). If used correctly, it provides rapid pain relief with minimal systemic effects.

Important precautions: Lidocaine 2% viscous carries a strong warning against use in very young children. Fatal overdoses (seizures, heart and breathing arrest) have been reported in infants and toddlers when the solution was mistakenly swallowed or overused. Therefore, it is never given to teething infants, and use in children under ~3 years is extremely limited. Even in older children and adults, the total dose per hour/day must not be exceeded (per the label). Other precautions: avoid contact with open wounds beyond the mouth, do not use if allergic to local anesthetics, and use carefully if the patient has heart or liver problems.

In summary, Lidocaine viscous 2% is a thick oral rinse (topical solution) containing lidocaine that dentists and doctors use to numb mouth and throat tissues. It provides quick, temporary relief of oral pain or discomfort (and can reduce gagging) by blocking nerve signals in the applied area. It should be used under medical guidance, with caution especially regarding dosage and pediatric use.
