Can cetirizine or fexofenadine help if nasal congestion worsens sleep apnea?

Nasal congestion from allergic rhinitis can make sleep apnea worse. Cetirizine and fexofenadine are antihistamines that help reduce allergy symptoms like nasal congestion. According to the provided references, allergic rhinitis is closely linked to sleep issues, including sleep apnea.

• Allergic Rhinitis and Sleep Apnea: Allergic rhinitis can lead to blocked nasal passages, which might worsen sleep apnea. This condition can cause poor sleep quality and daytime tiredness.
• Role of Antihistamines: Cetirizine and fexofenadine are medications that can relieve nasal congestion by reducing the body's allergic response. This might help improve breathing during sleep.

While these medications can help with nasal congestion, it's important to talk to a healthcare provider to see if they are right for you and to explore other treatments for sleep apnea.
