Medication for Snoring: Nasal Sprays Explained

The right question is not simply “Which medication stops snoring?” but “What problem am I trying to treat?” A blocked nose, allergic rhinitis and a sleep-related breathing disorder need different approaches. Products described as nasal sprays can also have very different purposes.

Asonor bottle and packaging on a bedside table — Check the intended use of the specific product, not just the words “nasal spray.”

Allergy medicines address allergy symptoms

Antihistamines and intranasal corticosteroids are used for allergic rhinitis. Antihistamines can help symptoms such as sneezing and a runny nose; steroid nasal medicines are commonly used for nasal symptoms. A pharmacist or clinician can advise which is appropriate.

This does not make an allergy medicine a universal snoring treatment. If allergies are suspected, describe the nasal symptoms and their timing rather than selecting a product solely because you snore. Read our hay fever and snoring guide for more context.

Decongestants are a different category

Decongestants reduce swelling in the nose and provide short-term relief of congestion. They are not suitable for everyone. Check with a pharmacist before use if you take other medicines or have conditions such as high blood pressure or heart problems.

Current UK advice: on 30 April 2026, the MHRA limited use of nasal decongestant sprays containing xylometazoline or oxymetazoline to a maximum of five days. Prolonged use can cause rebound congestion. The regulator advises following this update even where older packaging still says seven days.

This advice concerns those specific decongestants, not every nasal product. Outside the UK, check current local guidance and the product information with a pharmacist. If congestion persists, seek advice rather than repeatedly extending use.

How Asonor differs

Asonor is a medical device with a physical action: local lubrication and hydration of the mucous membranes in the throat. Its jet-stream applicator delivers the solution through the nostrils towards the pharyngeal area. It is not an antihistamine, corticosteroid or nasal decongestant.

It is intended to reduce snoring, with individual results varying. It does not treat sleep apnea or replace prescribed treatment. The current Asonor instructions for use provide the directions and precautions for this product. Do not transfer dosing or application instructions from a different spray.

Five questions to take to the pharmacy

What is the product intended to address? Describe the symptom you want help with and ask whether the proposed product matches it.
Is it suitable for me? Mention current medicines, medical conditions and any other relevant circumstances.
How should I use this particular product? Ask about technique, frequency and duration.
When should I expect a review? Agree what to do if the symptom persists or the product causes problems.
Am I duplicating an ingredient? Bring the names or packaging of any cold, allergy or sleep products you already use.

A short written list makes it easier to leave with clear instructions. Avoid adding several remedies at once simply because the first choice did not immediately solve the noise.

When a spray is not the next step

Breathing pauses during sleep, choking or gasping, and persistent daytime sleepiness warrant medical assessment. Possible sleep apnea requires a proper evaluation; trying a succession of over-the-counter products should not delay it.
