Tessalon Overdose, Contraindications and Information - Benzonatate
Tessalon Overdose, Contraindications and Information - Benzonatate
OVERDOSE
Overdose may result in death. The drug
is chemically related to tetracaine and other topical
anesthetics and shares various aspects of their pharmacology and toxicology.
Drugs of this type are generally
well absorbed after ingestion.
Signs and Symptoms
If softgels are chewed or dissolved in the mouth,
oropharyngeal anesthesia will develop rapidly. CNS
stimulation may cause
restlessness and tremors which may proceed to clonic
convulsions followed by profound CNS
depression.
Treatment
Evacuate gastric contents
and administer copious amounts of activated charcoal slurry. Even in the
conscious patient,
cough and gag
reflexes may be so depressed
as to necessitate special attention
to protection against aspiration of gastric
contents and orally administered materials. Convulsions should be treated
with a short-acting barbiturate given intravenously and carefully titrated
for the smallest effective dosage. Intensive support of respiration
and cardiovascular- renal function
is an essential feature
of the treatment of severe
intoxication from overdose.
Do not use CNS stimulants.
CONTRAINDICATIONS
Hypersensitivity to benzonatate
or related compounds.
