GENERIC NAME: chlorpheniramine and pseudoephedrine
DISCONTINUED BRAND: Deconamine
DRUG CLASS AND MECHANISM: 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.
SIDE EFFECTS: 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:
- hallucinations, and
- convulsions (seizures).
