Decongestants help open up nasal passages thus allowing for easier breathing. Indications and route of administration. Example of oxymetazoline nasal spray. Decongestants are mainly used in conditions like common cold, allergic rhinitis, and sinusitis. They provide temporary relief from symptoms of nasal congestion.
Oxymetazoline, sold under the brand name Afrin among others, is a topical decongestant and vasoconstrictor medication. It is available over-the-counter as a nasal spray to treat nasal congestion and nosebleeds, as eye drops to treat eye redness due to minor irritation, and (in the United States) as a prescription topical cream to treat persistent facial redness due to rosacea in adults.
The decongestant effect is due to constriction of large veins in the nose which swell up during the inflammation of any infection or allergy of the nose. The smaller arteries are also constricted and this causes the colour of the nasal epithelium to be visibly paler after dosage.
