If a patient has pain in the throat after inhaling formaldehyde, it is usually due to the congestion and edema of the mucous membrane in the throat. Patients are advised to take oral laryngeal pain granules or Lianzhi anti-inflammatory capsules, which can also be applied together with Blue Scutellaria Oral Liquid. If the patient’s throat pain is particularly obvious, he can take oral cephalosporin antibiotics, such as cefradine capsules. If necessary, hormone therapy can be applied, which can quickly reduce swelling and pain. However, the specific dosage or whether the patient can apply hormones for treatment needs further guidance from the hospital doctor. Patients are advised not to inhale formaldehyde again, and not to eat spicy and stimulating food, and to go to the hospital for further consultation if necessary to avoid delaying the patient’s condition.
