Butane is a flammable hydrocarbon gas used in fuel products. It is not a medication.

Butane information
Chemical and product context
Lighter fuel and aerosol mixtures can contain butane or related hydrocarbons. A product name may describe a mixture rather than pure n-butane.
Sources: CDC/NIOSH — n-Butane
Exposure hazards
High exposure can cause dizziness, drowsiness and asphyxia. Contact with liquefied gas can cause cold injury. Fire and explosion risks are also important.
Sources: CDC/NIOSH — n-Butane
No human-use dose
Workplace exposure controls are not instructions for inhalation. Serious symptoms after gas exposure require urgent medical assessment.

n-Butane and related names
The NIOSH entry concerns normal butane. Isobutane is a separate isomer, and commercial fuel may be a mixture. A broad butane label does not resolve the exact composition of every fuel or aerosol product.

Compressed gas and liquid contact
Butane is commonly supplied as a liquefied compressed gas. Expansion and contact with the liquid can create cold-injury hazards that differ from the effects of breathing a high gas concentration.
Sources: CDC/NIOSH — n-Butane
Oxygen displacement and alertness
High concentrations can impair alertness and displace oxygen. Loss of consciousness in an affected space creates risks beyond a simple transient feeling of dizziness. Fire and explosion hazards may exist at the same incident.

Butane versus propane
Both are hydrocarbon fuels, but they are different chemicals with different physical properties. A shared commercial use does not make their safety data or exposure limits interchangeable. This directory treats them as exposure references, not drug formulations.
