A hypertonic seawater spray with copper for a blocked nose
Sterimar Copper Hypertonic Nasal Spray Blocked Nose is a hypertonic seawater nasal spray from Sterimar for a blocked nose, for both children and adults. Hypertonic means the seawater is more concentrated than the body’s own fluids, and this version is enriched with copper, a trace element Sterimar uses in this line.
How it works
A fine mist sprayed into each nostril. The salt concentration draws moisture out of the nasal lining, which is why hypertonic sprays are used when the nose feels congested. The 100ml bottle lasts through a few weeks of colds.
Who it suits
- Children and adults with a blocked nose
- Cold and allergy seasons
- Anyone who prefers a seawater-based product
- Families sharing one nasal spray
Worth knowing before you buy: A hypertonic spray can feel stronger than an isotonic one, so keep the isotonic version for everyday hygiene. Follow the age guidance on the box.
