Clinically, there is no medicine that can quickly restore the sense of taste and smell; the common causes of taste and smell failure are colds, allergic rhinitis, nasal polyps and so on.
1. Colds: Colds are mostly caused by bacterial infections, which may lead to transient loss of taste and smell. Patients can take topical or oral pseudoephedrine hydrochloride, phenylephrine and other drugs under the guidance of the doctor, and the symptoms of loss of taste and smell can be restored.
2. Allergic rhinitis: As the nasal mucosa is stimulated by bacteria, viruses, allergens and other pathogens for a long period of time, it will lead to loss of taste and smell. You can take oral loratadine and other drugs under the guidance of the doctor for treatment, and if necessary, you can use budesonide nasal drops and so on.
3. Nasal polyps: Nasal polyps are redundant organisms that grow on the mucosa of nasal cavity and sinuses. Smaller nasal polyps generally do not cause discomfort, but larger nasal polyps may cause compression of local nerves, resulting in loss of taste and smell; they can be treated with drugs such as oral prednisolone and diphenhydramine, and surgical resection to restore the sense of taste and smell, if necessary.
At the same time there are many reasons for taste and smell loss or disappearance, should actively go to the hospital, under the guidance of professional doctors to clarify the cause of the disease after standardizing the use of medication and treatment, do not self-diagnosis and treatment.
