I'm sorry to hear that you're experiencing frequent sneezing every morning. This is often related to allergies, which occur when your immune system reacts to harmless substances called allergens. Common morning triggers include dust mites in bedding, pollen, or pet dander.

You mentioned taking Allercet-L, which contains levocetirizine, a non-drowsy antihistamine. This medication works by blocking histamine, a chemical your body releases during allergic reactions, helping to reduce symptoms like sneezing, runny nose, and itching.

Why does sneezing happen mostly in the morning?

• Allergens such as dust mites tend to accumulate in bedding and pillows overnight.
• Cooler morning air can also irritate nasal passages.
• Indoor allergens may be more concentrated in the bedroom environment.

Recommendations:

• Regularly wash bedding in hot water to reduce dust mites.
• Keep windows closed during high pollen seasons.
• Use a vacuum with a HEPA filter to reduce indoor allergens.
• Continue taking Allercet-L as prescribed, but if symptoms persist or worsen, consult an allergist or an ear, nose, and throat (ENT) specialist for further evaluation and tailored treatment.

If you experience additional symptoms like difficulty breathing, swelling, or severe reactions, seek immediate medical attention.
