Nasal sprays for cold relief

Nasal sprays, also called nose sprays, are a commonly used treatment for colds which is available both over-the-counter and by prescription. Nasal congestion or blockage is one of the most common symptoms of colds and allergies. Nasal sprays can work quickly to ease congestion and remedy signs of a cold.

How do nasal sprays work?

Nasal sprays may help treat nasal allergy symptoms and cold symptoms. Sprays that are used to treat cold symptoms are available in two forms:

• Decongestant nasal sprays. These nasal sprays are available over-the-counter and by prescription. They help to clear nasal passages by causing blood vessels in the lining of the nose to constrict This reduces stuffiness and congestion. These nasal sprays should not be used for more than three days, depending on the medication, in order to prevent worsening of the congestion. When congestion worsens after using nasal sprays, it's called a "rebound effect".
• Salt water solutions. These saline nasal sprays are available over-the-counter to relieve mild congestion, loosen mucus, and prevent crusting. They contain no medication and can be used as frequently as needed without causing additional problems.

How do you use nasal sprays?

Here are the steps to follow when you use a nasal spray:

• Clear your nasal passageway by blowing your nose.
• Take the cap off the bottle and follow directions for shaking the bottle if necessary.
• Before you spray the medication into your nose, block one nostril by pressing a finger against it lightly.
• Put your thumb at the bottom of the pump bottle, or follow the directions if there is a different delivery system for the spray. The hole at the top of the bottle should be underneath your open nostril.
• Squeeze the pump and sniff gently. Then switch to the other nostril and repeat the process.

Some people would be well advised to avoid using some nasal sprays to remedy a cold. This includes people who have hypertension (high blood pressure) or other cardiovascular conditions, diabetes mellitus, thyroid problems, or urinary problems from benign prostatic hypertrophy, also known as an enlarged prostate.

Can nasal sprays worsen cold symptoms?

A condition known as rhinitis medicamentosa is caused by overusing some types of sprays. Overuse of nasal sprays causes the medication to become less effective and nasal congestion symptoms to reappear. This is also known as the "rebound effect". As a result, a patient who overuses nasal sprays becomes congested more frequently, and the nasal spray is effective for a shorter period time each time the patient uses it.
