To relieve a sore throat and dry cough, drinking plenty of fluids is important. Consuming cold foods like ice or ice cream, or hot foods like soups, can help. Honey lozenges can also be soothing. Acetaminophen can be taken for pain relief, and a DM syrup can help with a persistent cough. It's always a good idea to consult with a pharmacist for personalized advice. If pregnant, it's important to seek professional guidance before taking any medications, including natural health products and supplements. Be cautious with multi-ingredient cold or cough medications.
