Symptoms of overdose include cardiovascular system depression, CNS toxicity, and methemoglobinemia.

Used to provide topical anesthesia of accessible mucous membranes prior to examination, endoscopy or instrumentation, or other procedures involving the esophagus, larynx, mouth, pharynx or throat, respiratory tract or trachea, urinary tract, or vagina. Also used to suppress the gag reflex and/or other laryngeal and esophageal reflexes to facilitate dental examination or procedures (including oral surgery), endoscopy, or intubation. Also used for relief of canker sores, cold sores or fever blister.

Dyclonine is an oral anasthetic. If substantial quantities of local anesthetics are absorbed through the mucosa, actions on the central nervous system (CNS) may cause CNS stimulation and/or CNS depression. Actions on the cardiovascular system may cause depression of cardiac conduction and excitability and, with some of these agents, peripheral vasodilation.

Drugs that block nerve conduction when applied locally to nerve tissue in appropriate concentrations. They act on any part of the nervous system and on every type of nerve fiber. In contact with a nerve trunk, these anesthetics can cause both sensory and motor paralysis in the innervated area. Their action is completely reversible. (From Gilman AG, et. al., Goodman and Gilman's The Pharmacological Basis of Therapeutics, 8th ed) Nearly all local anesthetics act by reducing the tendency of voltage-dependent sodium channels to activate. (See all compounds classified as Anesthetics, Local.)

Readily absorbed through mucous membranes into the systemic circulation. The rate of absorption is influenced by the vascularity or rate of blood flow at the site of application, the total dosage (concentration and volume) administered, and the duration of exposure. Absorption from mucous membranes of the throat or respiratory tract may be especially rapid.

Approximately 30 to 60 minutes.

Local anesthetics block both the initiation and conduction of nerve impulses by decreasing the neuronal membrane's permeability to sodium ions. This reversibly stabilizes the membrane and inhibits depolarization, resulting in the failure of a propagated action potential and subsequent conduction blockade.
