Decongestant drugs

Drugs that are used to relieve nasal congestion commonly in people with upper respiratory tract infections. They work by narrowing blood vessels in the membranes lining the nose. This action reduces swelling, inflammation, and the amount of mucus produced by the lining. Common drugs include ephedrine, oxymetazoline, and phenylephrine. Small amounts of these drugs are present in many over-thecounter cold remedies. Taken by mouth, decongestant drugs may cause tremor and palpitations. Adverse effects are unlikely with nose drops, but if taken for several days they become ineffective and symptoms may then recur or worsen despite continued treatment.
