Diagnosis & Treatment

General Measures

  • Self-care and time is usually all that is needed for a cold. There is no cure for a cold. There are many remedies for cold symptoms. They include nonprescription cold preparations, getting extra rest, drinking plenty of fluids, and others that may be suggested by friends and family members. One or more of these may help you feel better until the body’s defenses fight off the germs.
  • To help relieve nasal congestion, use salt-water drops (1/2 teaspoon of salt to 1 cup of warm water). Put 2 or 3 drops of salt solution into each nostril
  • Don’t smoke. It can further irritate the nasal passages.


No drugs, including antibiotics, can cure the common cold. To help relieve symptoms, you may use nonprescription drugs, such as acetaminophen, decongestants, nose drops or sprays, cough remedies, and throat lozenges. It is best to get a product that works for one symptom, such as a runny nose, rather than a multi-symptom product. If you take other drugs, talk to your health care provider or pharmacist about possible drug interactions.


Best rest is not needed. Do reduce activity and exercise.


Regular diet. Drink extra fluids, including water, fruit juice, tea, and carbonated drinks.
