To help cure a sore throat without prescription medication like Benylin syrup, there are several non-pharmacological measures you can take. These include using saline solution to clean your nose, taking Tylenol for pain and fever, staying hydrated by drinking plenty of water, soothing your throat with honey, and gargling with salt water. It's also important to rest and avoid close contact with others to prevent spreading any infection. Remember that most people recover from a sore throat within 1 to 2 weeks without needing antibiotics.
