What are the medicines and treatments for a cold?

There are no medicines that can cure the common cold, but there are some simple but effective ways you can relieve your symptoms, as well as taking over-the-counter medicines for pain and fever or a blocked nose (nasal congestion).

Most people who have a cold and who are generally healthy and well will get better in 7–10 days without any treatment, because the body's immune system can take care of the infection on its own.

Colds are caused by a virus, so antibiotics won't help. Antibiotics do not kill viruses.

Rest is important if you have a cold because it helps your immune system fight the cold and can make you feel better.

See your doctor if your symptoms get worse or if your symptoms don't improve after 10 days.
