Along with their useful effects, most medicines can cause side-effects but not everyone experiences them.
Steroid nasal sprays rarely cause side-effects. Since the steroid spray is applied directly to the nose, very little of the steroid is absorbed into the body. However, occasionally side effects can occur. This will include nasal dryness, crusting or slight bleeding may occur. If these symptoms become recurrent or persistent, then treatment may need to be stopped. Please discuss this with a doctor or pharmacist.
Systemic side effects (affecting the rest of your body)
Systemic effects of nasal steroids may occur, particularly at high doses prescribed for longer periods. These effects are much less likely to occur than with oral steroids and may vary between different people.
Possible systemic effects may include Cushing's syndrome, Cushingoid features, adrenal suppression, cataract, glaucoma and more rarely, a range of psychological or behavioural effects including psychomotor hyperactivity, sleep disorders, anxiety, depression or aggression.
Tell your doctor or call NHS 111 and stop the nasal spray immediately if you notice any blurred vision or other problems with your vision.
There is a rare risk of Central Serous Chorioretinopathy (CSCR) which is where fluid builds up underneath the retina and can lead to retinal detachment. It tends to affect one eye.
Patients on ritonavir
Should not use steroid nasal sprays due to an increased risk of systemic side effects.
