Flonase is a popular over-the-counter (OTC) nasal spray used to treat allergic rhinitis, also known as hay fever. It works by reducing inflammation in the nasal passages, which helps to relieve symptoms such as sneezing, runny nose, and congestion. However, like any medication, Flonase can cause side effects. One of the most common side effects is a Flonase headache. 

What is flonase?

Flonase, also known by its generic name fluticasone propionate, is a nasal spray that belongs to a class of medications called corticosteroids. Corticosteroids work by reducing inflammation in the body, which can help to relieve symptoms associated with allergies and other conditions.

Flonase is approved for the treatment of allergic rhinitis, including seasonal and year-round allergies. It can be used by adults and children over the age of 4, although it is recommended that children under 12 use it under adult supervision.

What causes a flonase headache?

One of the most common side effects of flonase is a headache. The exact cause of a flonase headache is not fully understood, but it is thought to be related to the way that flonase works in the body.

Flonase works by reducing inflammation in the nasal passages. However, it can also reduce inflammation in other areas of the body, including the blood vessels in the head. This can lead to a decrease in blood flow to the brain, which can cause a headache.

In addition to reducing inflammation, flonase can also cause a drying effect in the nasal passages. This can lead to irritation and inflammation in the sinuses, which can also contribute to a headache.

Other potential side effects of flonase

In addition to a headache, there are other potential side effects of Flonase that you should be aware of. These include:

• Nasal irritation. Flonase can cause irritation in the nasal passages, which can lead to symptoms such as burning, stinging, and itching.
• Nosebleeds. Flonase can cause nosebleeds in some people, particularly those who use it for an extended period of time.
• Sore throat. Flonase can cause a sore throat in some people, particularly those who use it for an extended period of time.
• Cough. Flonase can cause a cough in some people, particularly those who use it for an extended period of time.
• Changes in taste or smell. Flonase can cause changes in taste or smell in some people.
• Eye irritation. Flonase can cause irritation in the eyes, particularly if it comes into contact with the eyes.
• Allergic reactions. Some people may be allergic to Flonase, which can cause symptoms such as hives, itching, and swelling of the face, tongue, or throat.

If you experience any of these side effects while using Flonase, you should speak to your doctor or pharmacist.

How to minimise flonase side effects

While Flonase can cause side effects, there are steps you can take to minimise the risk of experiencing them. These include:

• Use as directed. Follow the instructions on the label or as directed by your doctor or pharmacist.
• Use for the shortest time possible. Flonase should only be used for as long as necessary to control your symptoms.
• Use a lower dose. If you are experiencing side effects, your doctor or pharmacist may recommend that you use a lower dose of Flonase.
• Avoid contact with eyes. To minimise eye irritation, make sure to keep the spray away from your eyes and rinse your eyes with water if you accidentally get it in your eyes.
• Use saline spray. Using a saline nasal spray before using flonase can help to moisturise and soothe the nasal passages, which can reduce the risk of nasal irritation and nosebleeds.
• Drink water. Drinking water can help to keep the nasal passages hydrated, which can reduce the risk of nasal irritation and nosebleeds.
• Monitor your symptoms. If you experience any side effects while using flonase, make sure to monitor your symptoms and speak to your doctor or pharmacist if they persist or worsen.

When to seek medical attention

While most side effects of flonase are mild and go away on their own, there are some situations where you should seek medical attention. These include:

• Severe headache. If you experience a severe headache that does not go away, you should seek medical attention.
• Difficulty breathing. If you experience difficulty breathing or swelling of the face, tongue, or throat, you should seek medical attention immediately as these may be signs of a severe allergic reaction.
• Vision changes. If you experience vision changes while using Flonase, you should speak to your doctor or pharmacist as this may be a sign of increased pressure in the eyes.
• Persistent nosebleeds. If you experience persistent nosebleeds while using Flonase, you should speak to your doctor or pharmacist.
• Worsening of symptoms. If your symptoms worsen while using Flonase, you should speak to your doctor or pharmacist.

Takeaway

Flonase is a popular nasal spray used to treat allergic rhinitis.

To minimize the risk of experiencing these side effects, it is important to follow the instructions on the label, use for the shortest time possible, use a lower dose if necessary, and avoid contact with the eyes. If you experience any severe side effects, you should seek medical attention. As with any medication, it is important to weigh the benefits against the risks and speak to your doctor or pharmacist if you have any questions or concerns.
