What Is a Nasal Spray for Blocked Nose?
When a cold or flu strikes, a blocked nose can make even the simplest things — sleeping, eating, concentrating — feel like a real effort. The nasal spray for blocked nose you need should work quickly, be easy to use, and be clinically proven. Lemsip First Action Nasal Spray 20ml does exactly that. It contains xylometazoline hydrochloride 0.1%, a well-established decongestant active ingredient used widely across the UK to relieve nasal congestion caused by colds, flu, sinusitis, and allergic rhinitis. You can browse our full range of cold and flu remedies if you need additional symptom relief alongside this spray.
Nasal congestion happens when the blood vessels inside your nasal passages become inflamed and swollen, usually in response to a viral infection or allergen. This swelling narrows the airway, making it harder to breathe through your nose. Lemsip First Action Nasal Spray targets this directly at the source, offering relief that oral decongestants can sometimes take longer to deliver.
How Does Lemsip First Action Nasal Spray Work?
The active ingredient, xylometazoline hydrochloride 0.1%, belongs to a class of medicines called sympathomimetic decongestants. When sprayed into the nostril, it acts on alpha-adrenergic receptors in the nasal mucosa. This causes vasoconstriction — essentially, the blood vessels narrow — which reduces swelling of the nasal lining and allows air to pass through more freely.
- Xylometazoline binds to alpha-1 and alpha-2 adrenergic receptors in nasal blood vessels
- Vasoconstriction reduces blood flow to the swollen nasal mucosa
- Swelling decreases, opening the nasal passages
- Relief typically begins within minutes and can last several hours
Because it acts locally rather than systemically, the risk of cardiovascular side effects is lower compared to oral decongestants — though it is not entirely absent, particularly in people with certain health conditions.
Who Should Use Lemsip First Action Nasal Spray?
This spray is suitable for adults and children aged 12 and over who are experiencing nasal congestion. It is particularly useful when congestion is making it difficult to sleep, breathe comfortably, or go about daily life. That said, it is not appropriate for everyone.
- Adults aged 18 and over with cold or flu-related nasal congestion
- Adolescents aged 12–17 (under adult supervision)
- People with sinusitis-related blockage seeking short-term relief
- Those with allergic rhinitis who need temporary nasal decongestion
It is not suitable for children under 12, pregnant or breastfeeding women without medical advice, or people with certain cardiovascular or thyroid conditions. Always check the full list of contraindications before use.

How does Lemsip First Action Nasal Spray work in the body?
The active ingredient, xylometazoline hydrochloride 0.1%, is a sympathomimetic decongestant that acts on alpha-adrenergic receptors in the blood vessels of the nasal lining. This causes vasoconstriction — the vessels narrow — which reduces swelling and opens up the nasal passages. Because it acts locally rather than systemically, it tends to work faster than oral decongestants.
How do I use Lemsip First Action Nasal Spray step by step?
Start by blowing your nose gently, then hold the bottle upright and insert the nozzle into one nostril. Press the pump once while breathing in gently through your nose, then repeat in the other nostril if needed. Replace the cap after use and wipe the nozzle clean — never share the spray with anyone else for hygiene reasons.
How quickly does Lemsip First Action Nasal Spray start to work?
Most people notice relief from nasal congestion within a few minutes of using the spray. The decongestant effect can last for several hours, which makes it useful both during the day and before bedtime when a blocked nose can disrupt sleep. Individual response times may vary slightly.
What is the correct dose of Lemsip First Action Nasal Spray for adults?
Adults and children aged 12 and over should use one to two sprays into each nostril, up to three times daily. Do not exceed this dose and do not use for more than 7 consecutive days without speaking to a pharmacist or doctor. Always read the patient information leaflet supplied with the product.
Can I use Lemsip First Action Nasal Spray for more than 7 days?
No — you should not use this spray for more than 7 consecutive days. Using it for longer can cause rebound congestion, also known as rhinitis medicamentosa, where the nasal passages become more blocked when the spray is stopped. If your symptoms persist beyond a week, speak to your GP or pharmacist.
Who should not use Lemsip First Action Nasal Spray?
This spray is not suitable for children under 12, people with narrow-angle glaucoma, atrophic rhinitis, or those currently taking MAOIs or tricyclic antidepressants. People with high blood pressure, heart disease, hyperthyroidism, or diabetes should seek medical advice before use. Pregnant or breastfeeding women should also consult a healthcare professional first.
What are the side effects of Lemsip First Action Nasal Spray?
Common side effects include nasal dryness, a burning or stinging sensation, and sneezing shortly after use. Less commonly, some people experience headache, nausea, palpitations, or raised blood pressure. If you notice any serious or unexpected symptoms, stop using the spray and contact your pharmacist or GP.
How do I manage side effects of Lemsip First Action Nasal Spray?
Mild nasal dryness or irritation can often be eased by using a saline nasal rinse between doses to keep the nasal passages moist. If you experience palpitations, severe headache, or any cardiovascular symptoms, stop use immediately and seek medical advice. Never exceed the recommended dose in an attempt to get faster relief.
Can I use Lemsip First Action Nasal Spray during pregnancy?
You should not use this spray during pregnancy without first speaking to your doctor or midwife. Xylometazoline is a vasoconstrictor and its safety in pregnancy has not been fully established. Your healthcare provider can recommend a safer alternative if needed.
Is Lemsip First Action Nasal Spray suitable for children?
This particular formulation (0.1% xylometazoline) is not recommended for children under 12 years of age. For younger children, a lower-strength formulation (0.05%) may be appropriate, but only under medical guidance. You can explore our baby and toddler range for age-appropriate products.
What are the alternatives to Lemsip First Action Nasal Spray?
Other xylometazoline-based sprays such as Otrivine Adult Nasal Spray work in a similar way. Oxymetazoline-based products like Sudafed Blocked Nose Spray are another option. For a non-medicated alternative, saline nasal sprays can help rinse and moisturise the nasal passages without the 7-day restriction. You can browse our full ear, nose and throat collection for more options.
Can I use Lemsip First Action Nasal Spray alongside other cold medicines?
You can use it alongside many other cold remedies, but be cautious about combining it with oral decongestants containing pseudoephedrine or phenylephrine, as this may increase the risk of cardiovascular side effects. Always check with your pharmacist before combining medicines, particularly if you take any regular prescription medication.
What happens if I use too much Lemsip First Action Nasal Spray?
Using more than the recommended dose increases the risk of side effects including raised blood pressure, palpitations, and rebound congestion. If you or someone else has used too much, contact NHS 111 or your nearest pharmacist for advice. In cases of accidental ingestion, seek emergency medical attention immediately.
What is the latest research on xylometazoline nasal sprays?
Xylometazoline has been used as a nasal decongestant for decades and its efficacy and safety profile are well established in clinical literature. Current guidance from the NHS and BNF continues to support its short-term use (up to 7 days) for nasal congestion relief. No major new safety concerns have emerged in recent years, though rebound congestion with prolonged use remains a recognised risk.
