There's no cure for a cold or the flu. Antibiotics don't work against viruses. Stay home and rest, especially while you have a fever. Stop smoking and avoid secondhand smoke, which can make cold symptoms worse. Drink plenty of fluids like water, fruit juices and clear soups.
Fluids help loosen mucus.
Fluids are also important if you have a fever because fever can dry up your body's fluids, which can lead to dehydration. Don't drink alcohol. Gargle with warm salt water a few times a day to relieve a sore throat. Throat sprays or lozenges may also help relieve the pain. No medicine can cure a cold or the flu.
