Nasacort Allergy Nasal Spray contains triamcinolone acetonide, a nasal steroid. It is used to relieve the nasal symptoms of hay fever, such as sneezing, itching, and having a blocked, stuffy, or runny nose. You can buy Nasacort Allergy Nasal Spray from your pharmacy without a prescription. It is formulated in an adult spray and a children’s spray.

Doctor’s advice

How does it work?

Nasacort Allergy Nasal Spray is a steroid and works by reducing swelling and inflammation in the nasal passages, the root cause of the nasal symptoms of hay fever. It does this because of the corticosteroid it contains, a man-made version of a hormone normally produced by the body. This hormone controls part of our body’s inflammation levels, allowing this spray to reduce them.

How do I use the medication?

Initially, you should administer two sprays into each nostril once a day. Once your symptoms are under control, try reducing the dose to one spray into each nostril once a day. Children should start out with one spray in each nostril once a day. It can take Nasacort Allergy Nasal Spray three to four days before it starts to work. Therefore, it is best to use the medication regularly each day, so you can stop your symptoms before they occur.

If your symptoms do not go away after using Nasacort Allergy Nasal Spray for 14 days, you should speak with your doctor or pharmacist. Also, make sure you speak with your doctor before using the medication for longer than three months. 

Who should not use the medication?

Do not use the medication if you are allergic to any of its ingredients. Unless a doctor prescribes, anyone under 2 years should not use Nasacort Allergy Nasal Spray.

Make sure you speak with your doctor or pharmacist before using Nasacort Allergy Nasal Spray if you are pregnant or breastfeeding or have any problems with your nose, such as an injury, infection, ulcer, or recent surgery. You should also speak with your doctor or pharmacist before using this spray if you have glaucoma or cataracts.

Triamcinolone can interact with other medications, such as certain HIV medications and other corticosteroids. If you take any prescription, over-the-counter, or herbal medicines, ask your doctor or pharmacist whether it is safe for you to use Nasacort Allergy Nasal Spray.

Are there any side effects?

As with all medications, some people may experience side effects. If any side effects become bothersome, you should speak with your doctor or pharmacist. Some common side effects can include:

Seek urgent medical advice if you develop any problems with your eyes, such as blurred vision, cloudy vision, or loss of vision.
