The nasal sprays we use to relieve nasal congestion that affects the quality of life have side effects that may occur as a result of improper use.⠀ ⠀ Congestion may be due to viral and bacterial infections affecting your nose or sinuses, allergies, endocrine disorders, or a deviated septum. When substances such as Oxymethazoline or Xylomethazoline are sprayed into the nose, breathing through the nose becomes easier within a few minutes. This is due to the active ingredients reducing nasal resistance by constricting the blood vessels in the nasal mucosa and turbinates. If the nasal clearing spray continues to be used for longer than necessary, the swelling-stroke cycle is disrupted over time and eventually creates addiction and a disease called rhinitis medicamentosa occurs.⠀ ⠀ Improper and long-term use of nasal sprays can disrupt nose functionality, cause various side effects and cause permanent damage to the nose.⠀ ⠀ The nasal mucosa becomes irritated and dried as a result of nasal sprays used for a long time. This may later cause nosebleeds. Cilia, which are responsible for filtering the air in the nose, cannot function. Germ attack increases and causes you to get sick more often.⠀ ⠀ Side effects of nasal drops and/or sprays:⠀ ⠀ • The nasal mucosa burns and dries. ⠀ • Pulse may accelerate and blood pressure may increase. ⠀ • It may cause headache.⠀ • The mucous membrane swells again after the actual effect subsides. ⠀ • It may cause fatigue and insomnia.⠀ ⠀ Use nasal sprays as directed by your doctor. As general information, it should be kept in mind that nasal decongestant sprays should not be used after 5 days in children and 7 days in adults. Once addiction has formed, it is difficult to treat and may require surgery.
