The BAD news is that colds are caused by viruses. Around 200 viruses, all similar in their effects, are known to cause colds. There is no medication that will cure the cold virus. In most cases, you just have to be patient and let the virus run its course. Fortunately there are things you can do to relieve some of the symptoms.
Antibiotics have no effect against the virus that causes colds.
Colds are spread through secretion droplets, therefore it's best to use tissues, not your hands for covering a sneeze. Although there are none which will cure your cold, many can help relieve the symptoms and make your life more tolerable while the cold runs its course. Many cold tablets, capsules, and liquids contain ingredients which relieve more than one symptom. Pay attention to the listed contraindications and side effects on the label. Don't take any drugs if you are pregnant or think you might be pregnant without consulting your health care provider.
