Question about what medicine for a common cold

Condition analysis:
Your situation should be caused by a virus infection or A/H1N1 influenz. Please receive treatment as soon as possible.

Instructions:
Because there is no cure for the common cold, the best thing you can do is ease the symptoms. Over-the-counter (OTC) drugs can help with many different symptoms. However, you likely won’t experience all possible symptoms of a cold during every cold you have, so the drug that you choose will depend on your symptoms. They include the following:

Older antihistamines ("first generation")
Nonsteroidal antinflammatory drugs (NSAIDs)
Decongestants (vasoconstrictors)
Cough suppressants (narcotics)
Anticholinergics (ipratropium)

A common cold is a two step process. The first step is virus infection of nasal cells. The second step is the activation of the inflammatory mediators which directly cause the cold symptoms. Ideally, it is desirable to treat both parts of the process but currently drugs for treating the virus infection (antivirals) are not commercially available.
