The average dose necessary for effective antitussive therapy is between 10 and 45 mg, depending on the individual. The International Society for the Study of Cough recommends "an adequate first dose of medication is 60 mg in the adult and repeat dosing should be infrequent rather than qds recommended." [39]
In 1981, a paper by Gosselin estimated that the lethal dose is between 50 and 500 mg/kg. Doses as high as 15–20 mg/kg are taken by some recreational users. A single case study suggests that the antidote to dextromethorphan overdose is naloxone, administered intravenously. [17]
The dose of bupropion in the study was lower than the target dose recommended for clinical practice. [10] In this study, dextromethorphan/bupropion showed significantly greater improvement than bupropion alone in the first two weeks of treatment but not by week 6 of treatment in people with major depressive disorder.
Coricidin, Coricidin 'D' (decongestant), or Coricidin HBP (for high blood pressure), is the name of an over-the-counter cough and cold drug containing dextromethorphan (a cough suppressant) and chlorpheniramine maleate (an antihistamine). [1]
Doxylamine is generally safe for administration to healthy adults. Doses of doxylamine of up to 1,600 mg/day for 6 months have been given to adults with schizophrenia, with little toxicity encountered. [33] The median lethal dose (LD 50) is estimated to be 50–500 mg/kg in humans. [34]
For maintenance of blood pressure in hypotensive states, the dose for adults is 30 to 45 mg as a single dose, repeated as necessary or followed by intravenous infusion of 0.1% mephentermine in 5% dextrose, with the rate and duration of administration depending on the patient's response.

Cathartics such as sorbitol, magnesium citrate, magnesium sulfate, or sodium sulfate were previously used as a form of gastrointestinal decontamination following poisoning via ingestion. They are no longer routinely recommended for poisonings. [ 4 ]
