Over-the-Counter (OTC) Antiviral Medications
Over-the-counter antiviral medications like those containing docosanol and benzyl alcohol may help reduce the duration of a cold sore. It’s harmful to use any medications without consulting a doctor for the best line of treatment.
Antiviral medications are commonly used for flu. It’s best to use these medications once the infection begins. However, consult the doctor what is the best way to go about treatment.
Antiviral drugs also have their side effects. Some of the common adverse effects of these OTC medications include nervousness, nausea, poor concentration, diarrhea, and vomiting. Some drugs are also inadvisable for people with breathing problems like asthma.
