Colds are caused by viruses, so they can't be treated with antibiotics. There is no cure for the common cold, but you can ease symptoms and support your body's efforts to heal itself. No matter which symptoms you have, be sure to:

• Drink plenty of fluids (water or clear soup), and stay away from drinks with caffeine or too much sugar
• Don't smoke or drink alcohol
• Get plenty of rest
• Stay away from secondhand smoke
• Prevent the spread of cold viruses. Wash your hands often with soap and clean, running water for at least 20 seconds. If soap and water aren't available, you can use an alcohol-based hand sanitizer that contains at least 60% alcohol. Try not to touch your face with unwashed hands. Prevent close contact with others. And stay at home while you are sick.

• Take your temperature several times a day. If your fever is 100.4° F ( 38°C ) or higher for more than 1 day, call your doctor.
• Relax, lie down. Go to bed if you want. Just get off your feet and rest. Also drink plenty of fluids to prevent dehydration.
• Take acetaminophen or a nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen.

• Breathe steam or humidified air to open blocked nasal passages. Stand in a hot shower or use a cool mist humidifier. Clean the humidifer as recommended by the manufacturer.
• Saline nasal sprays and decongestant tablets or nasal sprays help open a stuffy nose.

• Gargle every 2 hours with 1/4 teaspoon of salt dissolved in 1/2 cup of warm water. Suck on throat lozenges and cough drops to soothe your throat.
• Cough medicines are available. But it's not clear how well they work.
• Take acetaminophen or an NSAID, such as ibuprofen, to ease throat pain. Follow package directions on how much to use and how often to take the medicine.

• Put fluids back into your body. Take frequent sips of clear liquids, such as water or broth. Stay away from drinks that have a lot of sugar in them. These include juices and sodas. These can make diarrhea worse. Older children and adults can drink sports drinks.
• As your appetite returns, you can go back to your normal diet. Ask your doctor if there are any foods you shouldn't have.

• You don't feel better after 7 days
