feel like you have a cold all the time, or if cold symptoms last more than 2
weeks, you may have allergies or sinusitis. Call your doctor.
What can you do for a cold?
Good home treatment of
a cold can help you feel better. When you get a cold:
- Get extra rest. Slow down just a little from
your usual routine. You don't need to stay home in bed, but try not to expose
others to your cold.
- Drink plenty of fluids. This can help soothe a sore throat and thin the mucus in your nose and lungs. Hot fluids—such as hot water, tea,
or soup with a lot of broth—help relieve a stuffy nose and head.
a humidifier in your bedroom and take hot showers to relieve a stuffy nose and
head. Saline drops may also help thick or dried mucus to drain.
- If you feel mucus in the back of your throat (postnasal drip), gargle with warm water. This will
help make your throat feel better.
- Use paper tissues, not
handkerchiefs. This will help keep your cold from spreading.

You may decide to try a cough, cold, or allergy medicine for your symptoms. Be safe with medicines. Read and follow all instructions on the label . Don't take cold medicine that uses several drugs to treat
different symptoms. For example, don't take medicine that contains both a
decongestant for a stuffy nose and a cough medicine. Treat each symptom on its
- You can take
acetaminophen (such as
Tylenol) or ibuprofen (such as Advil or Motrin) to relieve aches. If you give medicine to your child, follow what your doctor has told you about the amount to give.
- A decongestant can help with a stuffy nose. Don't use the medicine longer than the label says. Overuse of a nasal decongestant can cause rebound congestion. It makes your mucous membranes swell up more than before you used the spray.
- Cough preparations can cause problems for people who have certain health problems, such as asthma, heart disease, high blood pressure, or an enlarged prostate (BPH). Cough preparations may also interact with sedatives, certain antidepressants, and other medicines. Read the package carefully, or ask your pharmacist or doctor to help you choose.

Cough suppressants can stifle breathing. Use them with caution if you are older than 60 or if you have chronic respiratory problems.
Be careful with cold medicines. They may not be safe for young children, so check the label first. If you do give these medicines to a child, always follow the directions about how much to give based on the child's age and weight.

Alternative medicines or supplements
Some people try complementary or alternative medicines to prevent colds or to shorten their cold
symptoms. Before using any treatment for your cold symptoms, it is important to
consider the risks and benefits of the treatment. For more information, see the
Complementary Medicine. Some of the medicines being studied are:
Echinacea. Study results differ about whether echinacea can keep you from getting a cold or can help you get better faster. Echinacea can cause severe
allergic reactions in some people with a history of
asthma, allergies, hay fever, or eczema.
Vitamin C. Long-term daily use of vitamin C
in large doses does not appear to keep you from getting a cold or help you get better
faster. There may be a slight
reduction in the length of time cold symptoms last when high doses are taken.
Additional studies must be done to determine how much vitamin C is needed to
reduce the length of time cold symptoms are present.
Zinc. Using a product containing zinc may help shorten the length of your cold by up to a day.1 But you have to take the zinc as soon as you have any cold symptoms. In some cases, zinc products that you spray or place into your nose can cause permanent loss of the sense of smell.2
If you decide to use an alternative medicine or supplement,
follow these precautions:
- As with all conventional medicines and
supplements, it is important to follow the directions on the
