Flomist Nasal Spray is a prescription medicine used to relieve common allergy symptoms that affect the nose. It is mainly prescribed for people with allergic rhinitis, whether symptoms occur during certain seasons (such as pollen seasons) or throughout the year. In some cases, it is also used to help manage nasal polyps, which are small growths inside the nose that can cause blockage and discomfort.
This medicine works directly in the nose to reduce swelling and irritation. Because it is applied locally as a nasal spray, it targets the problem area rather than acting throughout the whole body. When used correctly and regularly, Flomist can help reduce a blocked or runny nose, sneezing, and itching, allowing people to breathe more comfortably and go about their daily activities with fewer allergy-related disruptions.
What it is and what it is used for
Active ingredient and medicine class
Flomist Nasal Spray contains fluticasone propionate as its active ingredient. Fluticasone propionate belongs to a group of medicines called corticosteroids. Corticosteroids help reduce inflammation (swelling and irritation) in the body. When used in the nose, they act on the lining of the nasal passages to calm allergic reactions.
Conditions it is used to treat
According to the source information, Flomist is prescribed for the following conditions:
- Seasonal allergic rhinitis, such as hay fever
- Perennial allergic rhinitis, which causes symptoms all year round
- Nasal polyps (small growths inside the nose)
These conditions often lead to symptoms such as:
- A blocked or congested nose
- Sneezing
- A runny nose
- An itchy nose
Flomist helps manage these symptoms by reducing swelling inside the nasal passages, making it easier to breathe.
How it works
Allergies in the nose happen when the immune system reacts to substances like pollen, dust, or animal dander. This reaction causes inflammation, which leads to swelling, extra mucus, and irritation. Flomist works by calming this inflammatory response.
Fluticasone propionate reduces the release of substances in the body that cause inflammation. When sprayed into the nose, it helps shrink swollen tissues and lowers mucus production. This does not provide instant relief like some decongestant sprays, but it treats the underlying inflammation. Because of this, it may take a few days of regular use before you feel the full benefit.
Who should NOT use this medicine
Do not use Flomist Nasal Spray if any of the following apply to you:
- You are allergic to fluticasone propionate or to any of the other ingredients in the spray
- You have an untreated infection inside your nose
- You have recently had nasal surgery or a nasal injury that has not fully healed
If you are unsure whether any of these situations apply to you, speak to your doctor or pharmacist before starting the spray.
Warnings and precautions (Read before use)
Before using Flomist Nasal Spray, it is important to discuss your medical history with your doctor. Tell your doctor if you:
- Have or have had tuberculosis
- Are currently being treated for any infection
- Have eye conditions such as glaucoma or cataracts
- Are using ritonavir for HIV treatment
- Are taking or using any other steroid medicines, including tablets, inhalers, or creams
Using more than one steroid medicine at the same time may increase the risk of side effects. Your doctor will decide whether Flomist is suitable for you and whether any monitoring is needed.
Warning: Using higher doses than prescribed or using the spray for a long time without medical supervision can increase the risk of hormone-related side effects.
Pregnancy, planning pregnancy, and breastfeeding
If you are pregnant, planning to become pregnant, or breastfeeding, speak to your doctor before using Flomist Nasal Spray. Your doctor will consider the potential benefits and risks and decide whether it is safe for you to use this medicine. No further specific guidance is provided in the source.

- Ritonavir (used in HIV treatment)
- Other corticosteroid medicines, such as steroid tablets, inhalers, or creams
Using Flomist together with these medicines may increase the chance of side effects.

How to take (Step-by-step)
General dosing instructions
Always use Flomist Nasal Spray exactly as your doctor has told you. Do not change your dose unless your doctor advises you to do so.
The usual doses are:
- Adults and children over 12 years: 2 sprays into each nostril once daily
- Children aged 4 to 11 years: 1 spray into each nostril once daily
How to use the spray correctly
Using the spray properly helps ensure that you get the best results. Follow these steps:
- Shake the bottle gently.
- If the spray is new or has not been used for more than 7 days, prime the pump by spraying into the air until a fine mist appears.
- Blow your nose gently to clear your nostrils.
- Insert the nozzle into one nostril and close the other nostril with a finger.
- Breathe in gently through your nose while pressing the pump to spray.
- Repeat the process in the other nostril.
- Wipe the nozzle clean and replace the cap.
Use the spray regularly, even if your symptoms improve. It may take a few days before you notice the full effect.
Missed dose
If you forget to use a dose, use it as soon as you remember. If it is almost time for your next dose, skip the missed dose. Do not use extra sprays to make up for the missed one.
Overdose
Using more Flomist than prescribed will not improve your symptoms and may increase the risk of side effects. Long-term use of high doses may lead to hormone problems, such as adrenal suppression, and in rare cases may affect growth in children. If you accidentally use too much, contact your doctor or pharmacist for advice.
