Like all medicines, Beconase nasal spray can cause side effects, although not everybody gets them. Most side effects are mild and occur in the nose or throat, particularly when treatment is first started or if the spray is not used correctly.Common side effects include: 

• Nosebleeds
• Dryness, irritation or soreness inside the nose or throat
• Unpleasant taste or smell after using the spray

For some people with allergic rhinitis or other allergies, Beconase may not be the most suitable treatment. This is because it can interact with other medicines or may not be appropriate if you have certain medical conditions.

You should not use Beconase if any of the following apply to you:

• You are under 18 years of age
• You are allergic to beclometasone or any of the other ingredients in this medicine
• You have recently had surgery on your nose
• You have suffered a recent injury to your nose
• You are pregnant or breastfeeding, unless advised otherwise by a healthcare professional
• You have ulcers, sores or an infection inside your nose
• You have or have previously had tuberculosis (TB)

Your GP or pharmacist will assess whether Beconase is safe and suitable for you based on the information you provide about your medical history, current health conditions and any medicines you are taking. It is important to tell your healthcare professional if any of the above apply to you before starting treatment.
