Sprays nasais de esteroides

What are steroid nasal sprays?

A steroid nasal spray is a small bottle of a solution which you spray into your nose. It contains a medicine called a corticosteroid or steroid. Steroid sprays reduce swelling (inflammation) and mucus in the nose, and usually work well.

Because the medicine is mainly absorbed in your nose, it has very little effect anywhere else in your body. Therefore they are considered to be very safe to use.

A steroid nasal spray is commonly used to treat symptoms of the nose such as:

• Blocked nose.

• Runny nose.

• Congestion of the nose.

• Itchiness of the nose.

These symptoms may be caused by conditions such as:

• Allergies of the nose, como febre do feno.

• Inflammation of the nose (persistent rhinitis).

• Swelling (polyps) in the nose.

A steroid nasal spray may also be used to treat other conditions such as:

• Sinusite crônica.

• Sinusite aguda.

• Disfunção da tuba auditiva.

There are a number of different steroid nasal sprays - these include beclometasona, budesonida, fluticasona, mometasone e triamcinolone. They come in different brands. Ciclesonide and flunisolide are other steroid nasal sprays (they are not available in the UK).

Steroid nasal spray administration

• Blow your nose.

• Shake the bottle.

• Tilt your head forwards.

• Hold the spray bottle upright.

• Insert the tip of the spray bottle just inside one nostril. Close the other nostril with your other hand, and apply one or two sprays as prescribed.

• Breathe in as you spray (but do not sniff hard as the spray then travels past the nose to the throat).

• Do not angle the canister towards the middle or side of the nose, but straight up. With your head tilted forward, the spray should go to the back of your nose.

• Repeat in the other nostril.

What if my nose is very blocked or runny?

Sometimes a very blocked or runny nose will prevent the steroid spray from getting through to work. A decongestant nasal spray which you can buy at pharmacies may then be useful. These contain decongestant medicines such as xilometazolina.

A decongestant spray has an immediate effect to clear a blocked nose. You can then use the steroid spray once the nose is clear.

What if my symptoms come and go?

If your symptoms are very mild, if they don't happen all that often or if they only start after a particular trigger - for example, if you have a cat allergy - a steroid nasal spray may not be the best treatment for you. A nasal spray containing a type of medicine called an antihistamine (such as azelastine or olopatadine) may be better. Only azelastine is available in the UK.

It takes several days for a steroid spray to build up to its full effect. Therefore, you will not have an immediate relief of symptoms when you first start it. In some people it can take up to two weeks or longer to get the maximum benefit.

If you use the spray for hay fever, it is best to start using it at least a couple of weeks before the hay fever season starts.

Some people only need a nasal spray for the hay fever season (a few months). However, if you have a persistent rhinitis, you may have to take treatment long-term to keep symptoms away.

Once symptoms are gone, you are still likely to need to use a steroid nasal spray regularly, to keep symptoms away. Your doctor may advise that you reduce the dose to a lower maintenance dose once symptoms have gone. The aim is to find the lowest dose that controls symptoms.

An occasional forgotten dose should not be a problem, but symptoms usually return after a few days if you stop taking the spray.

Steroid nasal sprays rarely cause side-effects. This is because they are applied directly to the nose and very little of this medicine is absorbed into the body. Therefore, they are much less likely to cause side-effects in other parts of the body. Occasionally, they cause dryness, crusting, and bleeding of the nose.

If this occurs, stop it for a few days and then restart. There have been reports of nasal steroids possibly having an effect on behaviour, particularly in children. This is thought to be rare. However, a few people have reported hyperactivity, problems sleeping, ansiedade, depressão, and aggression.
