Athomer Nasal Sprays & Nasal Wash Products

Athomer is a specialist range of sterile seawater nasal sprays and nasal wash products designed to gently cleanse, hydrate and decongest the nasal passages. Using isotonic or hypertonic sea water rich in natural minerals and trace elements, Athomer products help to thin mucus, clear allergens and support easier breathing in adults and children. They are often used for everyday nasal hygiene, colds and flu, sinus congestion and allergy-related blocked noses, alongside treatments from our nasal congestion and cold remedies collections.

What is Athomer?

Athomer nasal sprays and wash systems are sterile seawater solutions prepared from carefully selected marine sources. The solutions are typically isotonic (similar salt concentration to the body) or hypertonic (slightly higher concentration), helping to:

• Loosen and thin thick mucus inside the nose.
• Rinse away dust, allergens and pollutants.
• Moisturise dry nasal mucosa.
• Support natural nasal function and breathing comfort.

Athomer products are used as a mechanical, drug-free method of nasal cleansing rather than a medicated decongestant, making them suitable for many people including those who wish to limit medicine use, pregnant women (where appropriate) and children, when used according to age-specific instructions.

Common symptoms Athomer can help with

Athomer nasal sprays and washes are commonly used to ease:

• Blocked or stuffy nose due to colds and viral infections.
• Thick mucus, catarrh and post-nasal drip.
• Sinus pressure and congestion.
• Allergic rhinitis symptoms triggered by pollen, dust or pet dander.
• Dry, irritated nasal passages caused by central heating or air-conditioning.

Many people use Athomer alongside other treatments from our allergy medication, children’s allergy & hay fever and children’s cough, cold & flu collections, following advice from a pharmacist or doctor.

Benefits and features of Athomer nasal products

• Natural seawater base: Uses sea water rich in minerals and trace elements to support nasal mucosa health.
• Drug-free mechanism: Works mechanically to cleanse and hydrate, without systemic medicines.
• Sterile solutions: Prepared under controlled conditions to keep the solution sterile and safe for nasal use.
• Suitable for frequent use: Many products can be used several times daily for ongoing maintenance, as directed on the label.
• Range of formats: Fine-mist sprays, mini sprays and nasal wash systems to suit different ages and levels of congestion.
• Can be used alongside medicines: Complements other treatments for colds, sinusitis and allergies prescribed or recommended by your clinician.

Why nasal hygiene and hydration matter

The nose and nasal passages act as the body’s first filter for the air we breathe, trapping dust, viruses and allergens before they reach the lungs. When mucus becomes thick or the nasal lining is dry and inflamed, this natural defence works less effectively. Regular use of seawater nasal sprays such as Athomer can:

• Help remove trapped particles and allergens.
• Support the natural movement of cilia (tiny hairs that move mucus).
• Reduce nasal dryness, which can lead to cracking and discomfort.
• Improve comfort for people prone to recurrent sinus issues.

Good nasal care works especially well when combined with wider respiratory support, including products from our respiratory devices, asthma medication and cold remedies ranges, used as advised by healthcare professionals.

How to use Athomer nasal sprays and washes

Always follow the specific instructions on your Athomer product. General guidance includes:

• Nasal sprays: Gently blow your nose, then tilt the head slightly forward. Insert the nozzle into one nostril, aim slightly outwards (away from the septum) and press to deliver a fine mist. Repeat in the other nostril. Wipe the nozzle after use.
• Isotonic solutions: Suitable for everyday cleansing and hydration, and often for children and regular maintenance.
• Hypertonic solutions: Used more for decongestion and thick mucus, typically for shorter periods and following label guidance.
• Nasal wash systems: Usually involve preparing a saline solution using sachets, then gently flushing one nostril so the solution flows out the other, helping clear mucus and debris.
• Do not share nasal sprays or wash devices between people to avoid spreading infection.

Nasal sprays like Athomer may also be used before certain medicines (such as steroid nasal sprays) to clear mucus and allow better contact of the medicine with the nasal lining, if recommended by your doctor or pharmacist.

Who should use caution with Athomer

Athomer is generally well tolerated, but extra caution is needed if:

• You have recently had nasal or sinus surgery – only use as advised by your surgeon or ENT specialist.
• You have frequent nosebleeds or very fragile nasal mucosa.
• You have a known sensitivity to seawater or any additional ingredients listed on your specific product.
• You are using nasal products in very young children – always follow age limits and dosing guidance.

Parents should supervise use in children and consider wider illness support, including fluids and age-appropriate products from our rehydration treatments and children’s cough, cold & flu collections where appropriate.

Types of Athomer products you may find

• Athomer Isotonic Seawater Nasal Spray: For daily cleansing, hydration and mild congestion in adults and children (age limits depend on the specific product).
• Athomer Propolis or enhanced formulas: Isotonic seawater combined with additional natural components, used as directed on the label for nasal hygiene.
• Athomer Hypertonic Nasal Spray: Higher salt concentration designed to help relieve more stubborn congestion, typically in short courses.
• Athomer Nasal Wash System: Bottle or device plus salt sachets for deeper nasal rinsing and sinus care in older children and adults.

All products are drug-free mechanical aids and can sit alongside other lines in our nasal congestion and respiratory devices categories.

Athomer vs medicated nasal decongestants

Medicated nasal sprays containing decongestants work by narrowing blood vessels in the nasal lining, providing rapid relief but with a risk of rebound congestion if used for too long. Athomer, by contrast, uses seawater to physically rinse and hydrate the nose. Key differences include:

• No rebound congestion: Because Athomer is drug-free, it does not usually cause “rebound” stuffiness when stopped, as long as it is used as directed.
• Suitable for longer-term use: Many isotonic sprays can be used daily for extended periods, whereas medicated sprays are often limited to a few days.
• Complementary to medicines: Athomer can be used alongside products in our allergy medication and cold remedies ranges, when advised by a clinician.

For some people, a combination of seawater sprays and short-course medicated treatments gives the best balance of fast relief and longer-term nasal health.

FAQs about Athomer nasal sprays & washes

Is Athomer a medicine or a medical device?

Athomer seawater nasal sprays and washes are generally considered medical devices or mechanical aids rather than medicines. They work by physically rinsing and hydrating the nasal passages rather than delivering a drug into the body.

Can children use Athomer?

Many Athomer products are suitable for children above a certain age, but this varies by product. Always check the age guidance on the packaging and follow the instructions carefully. For younger children, you may also wish to explore other options in our children’s cough, cold & flu and children’s allergy & hay fever collections under professional advice.

How often can I use an Athomer nasal spray?

Frequency depends on the product and whether it is isotonic or hypertonic. Many isotonic sprays can be used several times a day or for daily maintenance, while hypertonic sprays may be recommended for shorter, symptom-focused courses. Always follow the directions on your specific product.

Can I use Athomer during pregnancy or breastfeeding?

Because Athomer is drug-free and based on seawater, it is often considered a suitable option for nasal hygiene in pregnancy or breastfeeding. However, you should still check the product information and consult your midwife, GP or pharmacist if you are unsure.

Can I use Athomer with other nasal sprays?

Yes, Athomer can often be used alongside medicated nasal sprays, for example using Athomer first to clear mucus and then applying a prescribed spray afterwards. Always confirm with your doctor or pharmacist, especially if you are using steroid or decongestant sprays.

What should I do if my nose feels worse after using Athomer?

Mild stinging or temporary discomfort can occasionally occur, especially on very dry or irritated mucosa, but this should settle quickly. If you experience persistent pain, burning, nosebleeds or worsening symptoms, stop using the product and speak to a healthcare professional.
