Medicine can help prevent or reduce snoring when it is caused by nasal congestion. Nasal congestion is usually caused by colds or allergies. Medicine may open the nasal passageway, permitting a smoother airflow and reducing snoring.
Decongestants (oral and nasal) and nasal corticosteroids both reduce nasal congestion. Be safe with medicines. Read and follow all instructions on the label . Don't use the medicine longer than the label says. Overuse of a nasal decongestant can cause rebound congestion. It makes your mucous membranes swell up more than before you used the spray.
