What it is used for
- Asthma (regular prevention of symptoms) — inhaled form
- Reducing airway inflammation to prevent asthma attacks
- Hay fever and persistent allergic rhinitis — nasal spray form
- Nasal congestion, sneezing, and runny nose due to allergy
How it works
Beclometasone is a steroid that calms inflammation in the airways or the lining of the nose. Used regularly, it reduces swelling and sensitivity, helping to prevent asthma symptoms or ongoing nasal allergy symptoms.
How it is taken
Available as an inhaler (preventer) for asthma and as a nasal spray for allergies. Both are used regularly rather than for instant relief. Use it exactly as your doctor, asthma nurse, or pharmacist directs. For the inhaler, rinsing your mouth after use can help reduce side effects.
No doses here on purpose. The right strength and schedule depend on you — only a doctor or pharmacist should set them. Always follow your prescription and the label.
Common side effects
- Oral thrush (a fungal mouth/throat infection) with the inhaler
- Hoarse voice or sore throat (inhaler)
- Dry or irritated nose, or mild nosebleeds (nasal spray)
- Unpleasant taste or smell
- Headache
Serious effects — get help
- Signs of a severe allergic reaction (swelling, difficulty breathing)
- Blurred vision or eye problems (rare, with long-term use)
- Symptoms of adrenal effects with high long-term doses (unusual tiredness, weight loss) — discuss with your clinician
- Repeated or severe nosebleeds with the nasal spray
If a reaction is severe — for example trouble breathing, swelling of the face or throat, or collapse — go to the nearest emergency room now or call your local emergency number. Do not wait for an online consultation.
Interactions to watch
- Certain antifungal and some HIV medicines (which can raise steroid levels)
- Other steroid medicines (added effect)
- Tell your clinician about all medicines, as combinations can occasionally matter
Who should take care
- Tell your clinician if you are pregnant, planning pregnancy, or breastfeeding
- Use it every day as prescribed, even when you feel well, for it to work
- Rinse your mouth after inhaler use to reduce thrush and hoarseness
- Tell any clinician you are using an inhaled or nasal steroid, especially if you become unwell or need surgery
- Do not stop suddenly without advice if you have used it long term
