Overdosage
If swallowed, activated charcoal may be useful. If spilled on the skin, remove contaminated clothing and wash skin with glycerol or with copious amounts of water. Treat contaminated eyes by flooding with water or sodium chloride 0.9% only for at least 10-15 min. Give IV sodium bicarbonate if metabolic acidosis is present.
Drug Interactions
Antimicrobial activity may be reduced by agents that increase pH.
Lab Interference
Absorbed phenol may interfere with ferric chloride test for urinary ketones or salicylates, test for ionised serum calcium, serum sulfonamide measurement, Benedict's test for glycosuria and estimation of plasma catecholamines by trihydroxyindole method.
Action
Description: Phenol is an antiseptic and disinfectant. It has also been used as local anaesthetic, neurolytic, sclerosing agent, and for the treatment of ingrowing toenails. When used in haemorrhoids as a sclerosing agent, it fixes the mucosa of the underlying muscles by producing submucosal fibrosis.
Pharmacokinetics:
Absorption: Absorbed from the GI tract and through skin and mucous membranes.
Metabolism: Metabolised to phenylglucuronide and phenyl sulfate; small amounts oxidised to catechol and quinol.
Excretion: Via urine (as metabolites); may tint the urine dark brown or green.
