Using the spray in the morning works best for most people.
The usual dose for adults aged 18 years and over, is 2 sprays into each nostril, once a day.
If your symptoms get better, try 1 spray into each nostril, once a day.
If your symptoms are especially bad, you may need 2 sprays into each nostril twice a day (morning and evening) until your symptoms improve.
Then go back to the usual dose.
Don’t use more than 4 sprays into each nostril in a day.
You may not get benefit straight away.
It can take 3 or 4 days for the spray to have its full effect.
