What causes frequent sneezing, and when is treatment needed?
Frequent sneezing can arise from nasal allergy, respiratory infection or irritation from smoke, fragrances or temperature changes. The sneeze count alone does not diagnose illness. Persistent symptoms or disturbed sleep and breathing warrant assessment rather than repeated random medicines.

Notice the pattern
Itching, watery eyes and discharge after dust or pollen exposure can suggest allergy without proving it. Non-allergic rhinitis may follow odours or weather changes; recording triggers helps assessment.
What may help?
Reduce smoke and known irritants. A pharmacist or clinician can select saline or suitable medicine according to cause, age, pregnancy and other conditions. Nasal rinsing requires sterile, distilled or previously boiled and cooled water and reliable preparation instructions.
Avoid decongestant overuse
Decongestant sprays can worsen blockage if used beyond their recommended duration. Seek review when symptoms persist, asthma worsens or one-sided symptoms continue. Facial swelling with breathing difficulty needs emergency care.
