Marimer Isotonic Hygiene Nasal Spray

Marimer Isotonic Hygiene Nasal Spray is supplied as a nasal spray, with 100% Natural Seawater and Purified Water (to make it isotonic, maintaining balance with body fluids). It is supplied in a pack size of 100ml.

No prescription is required for this product, as it is an over-the-counter (OTC) medicine. This page is limited to product, safety and handling information.

If you would like guidance before buying, you can speak to a doctor or pharmacist through an online consultation on DoctorOnCall. Orders are dispensed by a registered pharmacist and delivered to your address.

Tilt your head slightly and gently insert the nozzle into one nostril. Press briefly for a gentle spray, then remove the nozzle and allow any excess solution and loosened mucus to drain out, gently blowing your nose afterwards if needed. Repeat for the other nostril. For babies and young children, a caregiver should hold the bottle and apply the spray gently, wiping away any excess with a soft tissue afterwards. Clean the nozzle after each use.

As a non-medicated hygiene spray, there is no fixed pharmacological dose. General usage guidance is one to two sprays into each nostril, one to three times a day, or as directed by a healthcare professional. It is considered suitable for daily use across age groups; for infants and young children, an adult should supervise and administer the spray, and a doctor or pharmacist can advise on suitable frequency if there is any uncertainty.

Use before the expiry date printed on the bottle and carton. As with most multi-dose nasal sprays, check the packaging for any stated period of use after first opening (commonly a few months), and discard the bottle once that period has passed, even if some solution remains, or sooner if the solution appears discoloured or the nozzle is damaged.

Store below 25°C, away from direct sunlight and heat, and out of reach and sight of children. Keep the bottle upright with the cap closed between uses, and do not freeze.

• Common: A mild stinging sensation in the nose immediately after use.
• Common: Sneezing or temporary nasal irritation after spraying.
• Serious: Persistent irritation or nosebleeds are uncommon; stop use and seek medical advice if these occur.

• Not for use in individuals with a known hypersensitivity to seawater-based nasal products.
• Not intended for use in the ears or eyes; use only in the nose as directed.
• Not a substitute for prescribed treatment of a diagnosed sinus infection or other underlying ENT condition.

• No clinically significant drug or food interactions are known for this seawater nasal spray, as it is not systemically absorbed.
• It can generally be used alongside other nasal medicines, typically applied first, before a medicated product is used, though a pharmacist can advise on the best order for your specific medicines.

• If you also use a decongestant or steroid nasal spray, apply this spray first, before the medicated product.
• Avoid sharing your bottle and nozzle with other family members, especially between children.
• Wipe the nozzle clean with a tissue after each use and keep the cap on between uses.
• Some people choose to use it more frequently during haze season, long flights, or extended time in air-conditioned rooms.
• For babies and toddlers, use gentle pressure only and have a soft tissue ready to wipe away loosened mucus.
• Because it is non-addictive and preservative-free, it can be used as part of a regular daily hygiene routine without dependency concerns.

Marimer Isotonic Hygiene Nasal Spray is a non-medicated, seawater-based hygiene product for use across age groups; it is not a treatment for a diagnosed sinus infection or structural nasal condition.

Precautions: Use only in the nose and avoid spraying into the eyes. Use gentle pressure in infants and young children, as forceful spraying may in rare cases allow solution to travel toward the middle ear. If your child has a history of frequent ear infections or any diagnosed ear condition, check with a doctor or pharmacist before regular use.

When to See a Doctor or Pharmacist: See a doctor or pharmacist if nasal congestion or discomfort lasts more than seven to ten days, if symptoms worsen, if there is blood in the nasal discharge, facial pain or swelling, high fever, or signs of an ear infection, as these may need separate medical assessment.
