As we know by now, antibiotics cannot be used to treat the common cold or flu and taking antibiotics for the common cold or flu would only do harm. Unfortunately, most viral infections cannot be cured automatically. Although there are antiviral medications to treat some viral infections, treatments can only help with symptoms while you wait for your immune system to fight off the virus.3 Fortunately, many viral infections can be prevented through vaccines, which is why it is important to be up-to-date on vaccinations and get the flu shot every year. Although antibiotics do not work against viral infections like the common cold or flu, you can still manage your symptoms without needing a prescription. Theraflu has the products to give you powerful relief for your cold and flu symptoms.
