Benadryl is the brand name for a range of products that are used to manage allergies. In the UK, most of these products contain a non-drowsy antihistamine. However, Benadryl nasal spray (known by its full name, Benadryl Allergy Natural Relief Nasal Spray) is a natural and drug-free product.

Doctor’s advice

Who is it for?

Benadryl nasal spray is used to relieve nasal congestion caused by allergies like hay fever. It can also help with nasal congestion from other causes, such as colds, flu, and sinusitis, and it is suitable for all ages.

As the product is drug-free, it will not interact with your medications. This makes it a good choice for people who need to take lots of different medications. It also means you can use Benadryl nasal spray alongside other allergy treatments, such as antihistamines and steroid nasal sprays.

The product is generally safe for most people to use, but you should avoid using it if you are allergic to any of the listed ingredients.

How does it work?

Nasal congestion occurs when your nasal passages become swollen (inflamed), which in turn can lead to an overproduction of mucus in your nose. This process can be triggered when allergens like pollen enter your nose and irritate the inner lining.

Benadryl nasal spray uses a saline solution (salt water) to provide natural relief of nasal congestion. It is not fully understood how the product works. However, it is thought to thin the mucus in your nose. It also cleans and moistens your nasal passages and helps remove allergens from your nose. These effects help to relieve that stuffy blocked-up feeling.

If you are using Benadryl nasal spray alongside another nasal spray, make sure you use your Benadryl nasal spray first to avoid flushing medication from the other nasal spray out of your nose.

Are there any side effects?

Most people that use Benadryl nasal spray do not experience any side effects. Occasionally some people may develop nosebleeds or irritation/discomfort inside their nose. These side effects are usually the result of overusing the medication.

How effective is it?

There has not been a vast number of studies that have analysed the effectiveness of saline products for managing nasal congestion, although the ones that have generally concluded that they do provide some benefit in relieving symptoms. There is not enough information available to conclude whether they are better or worse than drug-based (pharmacological) treatments like antihistamines and steroid nasal sprays.
