Snoring-Medications 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.
