What is chlorpheniramine, pseudoephedrine, and how does it work (mechanism of action)?
Deconamine was a brand name medication that contains two different drugs, an antihistamine (chlorpheniramine) and a decongestant (pseudoephedrine). The antihistamine effects of chlorpheniramine account for its effect of reducing allergy symptoms. The decongestant action of pseudoephedrine is a result of blood vessel constriction in the nasal air passages, such as in the nose or sinuses. Brand name and generic formulations of combination products containing only chlorpheniramine and pseudoephedrine have been discontinued in the U. S., most likely due to the regulation of pseudoephedrine distribution.
What are the side effects of chlorpheniramine, pseudoephedrine?
Side effects of antihistamines include:
- impaired ability to accurately operate machinery,
- worsening of glaucoma,
- worsening of asthma or chronic lung diseases,
- dry mouth or throat,
- low blood counts,
- ringing in the ears,
- stomach upset, and
- urinary frequency or difficulty.
Other important side effects of pseudoephedrine include stimulation of the nervous system leading to:

What is the dosage for chlorpheniramine, pseudoephedrine?
The combination drug may be taken with or without food. It must be used cautiously in patients with heart (coronary artery) disease and angina, diabetes, lung diseases, especially asthma, glaucoma, and narrowing of the stomach exit (pyloric stenosis).
Which drugs or supplements interact with chlorpheniramine, pseudoephedrine?
The combination drug can cause drowsiness and impaired ability to operate machinery. It contains pseudoephedrine which should not be taken with MAO inhibitors drugs. Caution must be exercised in the administration of this drug to patients with heart or lung disease. The combination drug should not be combined with other drugs containing pseudoephedrine (such as Sudafed) because of increased risk of side effects on the heart and blood vessels. While misuse of the combination drug for the purpose of getting "high" is unfamiliar to the editors, it is a specific warning from the manufacturer that patients be aware of possible "additive" effects of the drug when taken with alcohol and other central nervous depressants (such as sedatives and tranquilizers). This means that when the drug is taken with, for example, alcohol, the effect of the alcohol could be magnified. Conversely, alcohol increases the sedating qualities of Deconamine.

AllergyAn allergy refers to a misguided reaction by our immune system in response to bodily contact with certain foreign substances. When these allergens come in contact with the body, it causes the immune system to develop an allergic reaction in people who are allergic to it. It is estimated that 50 million North Americans are affected by allergic conditions. The parts of the body that are prone to react to allergies include the eyes, nose, lungs, skin, and stomach. Common allergic disorders include hay fever, asthma, allergic eyes, allergic eczema, hives, and allergic shock.
Chronic rhinitis and post-nasal drip symptoms include an itchy, runny nose, sneezing, itchy ears, eyes, and throat.

Treatment of chronic rhinitis and post nasal drip are dependent upon the type of rhinitis condition.
Common ColdThe common cold (viral upper respiratory tract infection) is a contagious illness that may be caused by various viruses.
