Will the tongue go numb immediately upon inhaling formaldehyde?

In general, whether the tongue immediately becomes numb after inhaling formaldehyde depends on the amount of exposure. If any discomfort occurs, it is recommended to seek medical attention promptly. The detailed analysis is as follows:

1. Immediate numbness may occur

Formaldehyde is an organic compound and a colorless gas with a pungent odor. Inhaling a large amount of formaldehyde in a short period may lead to formaldehyde poisoning, causing symptoms such as dizziness, headache, nausea, and vomiting. It may also irritate the tongue, resulting in a sensation of numbness.

2. No immediate numbness

However, if only a small amount of formaldehyde is inhaled, the stimulation to the body—and thus to the tongue—may be minimal, and immediate tongue numbness may not occur.

To prevent harm to the body, it is advisable to avoid environments containing formaldehyde. In cases of severe formaldehyde poisoning, treatment under a doctor's guidance with medications such as Niuhuang Jiedu Tablets, Huanglian Shangqing Tablets, or Compound Methoxyphenamine Capsules may be recommended to aid recovery.
