What is phenol oropharyngeal, and what is it used for?
Phenol oropharyngeal is a medication used to relieve pain from sore throat and mouth, canker sores and teething, and as a local antiseptic to protect minor cuts, scrapes, or burns in the skin from infection.
Phenol oropharyngeal temporarily relieves pain, but does not cure the underlying condition. Phenol is also an antibacterial agent that kills bacteria and prevents infection. Phenol oropharyngeal is available over the counter (OTC) in the U.S.
Is phenol oropharyngeal safe?
Phenol oropharyngeal relieves sore throat by numbing the mouth and throat. Phenol is a toxic compound that is easily absorbed from inhalation, skin contact, and ingestion. Phenol is a corrosive substance and can destroy tissue, but when used in minute percentages medicinally, it works as a local anesthetic and disinfectant.
