Beclometasone Nasal Spray: Uses, Dosage & Side Effects
Complete guide to beclometasone nasal spray: effectiveness, proper usage, and safety information.

What Is Beclometasone Nasal Spray?
Beclometasone nasal spray is a corticosteroid medication used to prevent and ease the symptoms of rhinitis, a condition where the inside of your nose becomes inflamed and irritated. This medication belongs to a class of drugs called corticosteroids and works by reducing swelling and inflammation in the nasal passages. It is available under several brand names, including Beconase, Nasobec, and Pollenase, and is available only with a doctor’s prescription.
What Is Rhinitis?
Rhinitis is a condition characterized by inflammation of the nasal lining, which leads to a range of uncomfortable symptoms. Common symptoms of rhinitis include sneezing, a blocked or congested nose, a runny nose with watery discharge, and an itchy nose. This condition is commonly caused by allergies, such as hay fever, but can also result from other triggers including vasomotor rhinitis, which is a nonallergic form of the condition.
How Does Beclometasone Nasal Spray Work?
Beclometasone nasal spray functions as a steroid (cortisone-like medicine) that works by preventing the inflammation that occurs with allergic reactions. When you use the spray, it reduces swelling and inflammation in the nasal passages, thereby relieving the symptoms associated with allergic rhinitis. The medication is designed to be used as a preventative treatment, meaning it works best when used regularly rather than as an occasional remedy for acute symptoms.
Uses of Beclometasone Nasal Spray
Beclometasone nasal spray has several important medical uses:
- Treatment of seasonal allergic rhinitis (hay fever)
- Treatment of perennial (year-round) allergic rhinitis
- Relief of symptoms caused by nonallergic vasomotor rhinitis
- Prevention of nasal polyps recurrence after nasal polyp removal surgery
- Management of stuffy, runny, or itchy nose symptoms
When to Start Using Beclometasone for Hay Fever
If you are using beclometasone nasal spray for hay fever, timing is crucial for optimal effectiveness. It is recommended that you start using the spray 2-3 weeks before the hay fever season begins and use it regularly throughout the season. This preventative approach allows the medication to build up in your system and provide better symptom control once the hay fever season arrives. It is important to note that it may take a few days of treatment before you feel the full effect of the medication, and some people may experience improvement within a few days while others may need up to 2 weeks to see the complete benefit.
Dosage Information
The appropriate dosage of beclometasone nasal spray varies depending on your age and specific medical condition. It is essential to follow your doctor’s or pharmacist’s instructions precisely, as individual needs may vary based on factors such as body weight, other medical conditions, and other medications you may be taking.
Dosage for Adults and Older Children
For adults and children 12 years of age and older, the typical starting dose is 2 sprays in each nostril once a day, with each spray containing 80 micrograms (mcg) of beclomethasone. However, some healthcare providers may recommend 2 sprays into each nostril twice daily (morning and night), with a typical dose of 1 or 2 sprays into each nostril per application. Once your symptoms are controlled, you may be able to reduce this to just one spray into each nostril twice daily.
Dosage for Children
For children aged 4 to 11 years, the recommended dose is 1 spray in each nostril once a day. For children over 6 years of age, the usual recommended dose is 2 applications into each nostril twice daily, with a maximum daily dosage not exceeding 8 applications. Children younger than 4 years of age should not use this medication unless the use and dose have been specifically determined by a doctor.
Maximum Daily Dosage
It is important not to exceed the maximum recommended dosage. Adults should not use more than 4 sprays per nostril in 24 hours. The daily dosage should not exceed 12 applications for adults or 8 applications for children.
How to Use Beclometasone Nasal Spray
Proper administration technique is essential for the medication to work effectively. Before starting treatment, read the manufacturer’s printed information leaflet from inside the pack, which will provide step-by-step guidance and a full list of potential side effects.
Step-by-Step Application Guide
- Gently blow your nose before using the spray to clear nasal passages.
- Close one nostril by placing a finger gently against one side of your nose.
- Bend your head forward slightly and carefully insert the nozzle of the spray into your other nostril, keeping the bottle upright.
- Begin to breathe in slowly through your nose.
- While breathing in, use your forefinger and middle finger to press firmly down on the applicator to release a spray.
- Breathe gently in through the nostril and breathe out through your mouth.
- If using two sprays, repeat steps 5-6 for the same nostril.
- Repeat the entire process with your other nostril.
- After using your spray, wipe the nozzle with a clean tissue and replace the cap.
Maintenance Tips
If the nozzle becomes blocked, you can remove it from the bottle and rinse it under warm water. Always keep the bottle upright during application to ensure proper spray delivery. It is crucial to use the medication as directed and not to use more or less of it than prescribed by your doctor.
Duration of Treatment
The length of treatment with beclometasone nasal spray varies depending on whether the medication is prescribed by a doctor or purchased over-the-counter. Treatment with beclometasone nasal spray can typically be continued for up to three months, though your doctor will advise you how long is right for your specific situation.
If you bought beclometasone nasal spray from a pharmacy or shop without a prescription, check the leaflet that comes with the medicine, which will tell you how long you can continuously use it without speaking to a doctor or pharmacist. This is usually between 1 and 3 months. Stop using it when you think you no longer need it, and ask your pharmacist for advice if you are unsure when to stop. If you are prescribed beclometasone, your doctor may advise you to use it for longer than the over-the-counter recommended period.
If your symptoms do not improve after using beclometasone nasal spray for 3 weeks, contact your doctor as it may indicate that a different treatment approach is needed.
