The symptoms of herpes pharyngitis in adults are roughly the same as in children. Some patients may have fever, and others may have abdominal pain and diarrhea. The main treatment is active antiviral and symptomatic treatment. Patients can take oral panaciclovir pellets, as well as busulfan anti-inflammatory oral solution for anti-disease treatment, and can spray the mouth with open throat sword spray, which can effectively promote the recovery of herpes mucosa. You can also rinse your mouth with compound tinidazole solution to avoid infection in the mouth. If the patient has a high fever, oral ibuprofen capsules or loxoprofen sodium tablets can be used to reduce the fever. In terms of diet, try to eat liquid food, if the patient is really difficult to eat, consider going to the hospital for rehydration treatment.
