2026 ICD-10-CM Diagnosis Code T42.6X2SPoisoning by other antiepileptic and sedative-hypnotic drugs, intentional self-harm, sequela

AHRQ’s CCSR groups this code into broader clinical categories.

• Bromine

  a halogen with the atomic symbol br, atomic number 35, and atomic weight 79.904. it is a volatile reddish-brown liquid that gives off suffocating vapors, is corrosive to the skin, and may cause severe gastroenteritis if ingested.

• Bromine Compounds

  inorganic compounds that contain bromine as an integral part of the molecule.

• Bromine Radioisotopes

  unstable isotopes of bromine that decay or disintegrate emitting radiation. br atoms with atomic weights 74-78, 80, and 82-90 are radioactive bromine isotopes.

• Bromisovalum

  a sedative and mild hypnotic with potentially toxic effects.

• Chlormethiazole

  a sedative and anticonvulsant often used in the treatment of alcohol withdrawal. chlormethiazole has also been proposed as a neuroprotective agent. the mechanism of its therapeutic activity is not entirely clear, but it does potentiate gamma-aminobutyric acid receptors response and it may also affect glycine receptors.

• Chlormezanone

  a non-benzodiazepine that is used in the management of anxiety. it has been suggested for use in the treatment of muscle spasm.

• Ethchlorvynol

  a sedative and hypnotic that has been used in the short-term management of insomnia. its use has been superseded by other drugs.

• Glutethimide

  a hypnotic and sedative. its use has been largely superseded by other drugs.

• Paraldehyde

  a hypnotic and sedative with anticonvulsant effects. however, because of the hazards associated with its administration, its tendency to react with plastic, and the risks associated with its deterioration, it has largely been superseded by other agents. it is still occasionally used to control status epilepticus resistant to conventional treatment. (from martindale, the extra pharmacopoeia, 30th ed, p608-9)

• Primidone

  a barbiturate derivative that acts as a gaba modulator and anti-epileptic agent. it is partly metabolized to phenobarbital in the body and owes some of its actions to this metabolite.

• Dipsacales

  an order of dicotyledonous flowering plants which includes six families. it is best known for its ornamental plants such as lonicera (honeysuckle), viburnum (arrowwood and guelder rose), and scabiosa (scabious, or pincushion flower).

• Valerian

  a plant genus of the family valerianaceae, order dipsacales, subclass asteridae, class magnoliopsida. it is best known for the sedative use and valepotriate content of the roots. it is sometimes called garden heliotrope but is unrelated to true heliotrope (heliotropium).

• Valerianaceae

  the valerian plant family of the order dipsacales, subclass asteridae, class magnoliopsida that is characterized by 3-5-lobed tubular flowers, often spurred at the base and clustered in tight heads.

• Valerianella

  a plant genus of the family valerianaceae. it is sometimes called goosefoot cornsalad but should not be confused with true goosefoot (chenopodium).

• Valproic Acid

  a fatty acid with anticonvulsant and anti-manic properties that is used in the treatment of epilepsy and bipolar disorder. the mechanisms of its therapeutic actions are not well understood. it may act by increasing gamma-aminobutyric acid levels in the brain or by altering the properties of voltage-gated sodium channels.

• Vigabatrin

  an analogue of gamma-aminobutyric acid. it is an irreversible inhibitor of 4-aminobutyrate transaminase, the enzyme responsible for the catabolism of gamma-aminobutyric acid and is used as an anticonvulsant. (from martindale the extra pharmacopoeia, 31st ed)

• Zolpidem

  an imidazopyridine derivative and short-acting gaba-a receptor agonist that is used for the treatment of insomnia.

Poisoning

A poison is any substance that is harmful to your body. You might swallow it, inhale it, inject it, or absorb it through your skin. Any substance can be poisonous if too much is taken. Poisons can include:
