What are Decongestants
Decongestants are medicines that relieve congestion by reducing swelling, inflammation and mucus formation. They may be taken orally or used directly in the nose or in the eye for a local effect. Their main action is stimulation of alpha-adrenergic receptors which vasoconstricts (narrows) blood vessels.
Decongestants are typically used for conditions associated with nasal or eye congestion, such as a cold, hay fever, rhinitis, sinusitis or allergies. Regular and long-term use (more than five to seven days) of a nasal decongestant has been associated with rebound congestion. Decongestants may also produce side effects such as CNS stimulation and an increase in blood pressure, and may not be suitable for people with high blood pressure or taking certain medications (such as monoamine oxidase inhibitors).
Decongestants are available as nose drops or nasal sprays, eye drops, and also as tablets, capsules, and syrup.
