The common cold is caused by a group of viruses known as the rhino viruses. And, taking antibiotics for the common cold increases the risk of antibiotic resistance - not a good idea. Numerous non-prescription remedies are available for the treatment of cough and cold symptoms. All of these products treat the symptoms making you more comfortable. There are five basic types of ingredients in cough and cold products - you have to read the fine print to determine what product contains what ingredients.
Antihistamines block histamine reactions in the body - runny nose, sneezing, watery eyes.
More often antihistamines are used for allergies such as hay fever, but because some of the symptoms are similar, they may provide some relief from cough and cold symptoms. The non sedating antihistamines are ideal for day time use when you need to be alert and the sedating one for bedtime use when you want to sleep uninterrupted by a drippy nose. Decongestants alleviate congestion enabling you to breath better. Because sinuses often become congested with colds, decongestants are found in many sinus products. Decongestants are available as both tablets and nasal spray.
