Many people begin feeling relieved from their allergies in about 12 hours, although not feeling any difference until the first day is also okay. Full efficacy of Flonase is usually reached in about 3 to 4 days of its use, therefore, it works best if used daily. This directly answers how long does Flonase take to work.
Flonase Allergy Relief is based on fluticasone propionate nasal spray, which is a corticosteroid medicine. It helps to reduce inflammation in the nasal passages. However, Flonase is not intended to cause quick relief from symptoms, which can be reached by using some nasal decongestant sprays. Flonase gradually builds its efficacy as the inflammation decreases.
Flonase Effectiveness Timeline
The Flonase onset of action may be different for various people depending on the severity of allergies, frequency of usage, as well as technique of applying it.
The average timeline is as follows:
First 12 hours – some people begin to notice Flonase for allergy relief
Day 1 – according to the current Flonase product information relief may start already during the first day of using the medicine
Days 1-2 – sneezing, nasal itching, runny nose, or congestion may become easier to handle
Days 3-4 – full effectiveness is usually reached in several days of consecutive daily use
After Day 4 – some people may continue to feel relief and improvement from their allergy symptoms.
According to clinical information for fluticasone propionate nasal spray, improvement from nasal allergies may be seen already in 12 hours after the initial dose of the medicine, although it may take several days to reach maximum effectiveness. As the manufacturer of Flonase states, the full effect is usually reached after three or four days of consecutive use.
So, if you used Flonase this morning and you still feel congested now, it does not mean that this medicine did not work.
Why Flonase Does Not Work Immediately
The answer to how long does Flonase take to start working differs from the effect of nasal decongestant.
Fluticasone propionate is a corticosteroid. When you have allergic rhinitis, allergens such as pollen, mold, dust mites, pet dander may cause inflammation of the nasal passages, irritation and swelling of the lining of the nose, increased production of mucus, sneezing and congestion.
Flonase helps to reduce inflammation in the nasal passages.
This process is slow and takes some time as the spray needs several applications in order to reduce inflammation in the nasal passages to its maximum. This is why fluticasone propionate how long to work can vary among patients.
The effect from a nasal decongestant is achieved in a short period of time as it constricts the blood vessels inside the nasal passages and makes them less congested. Flonase is not trying to achieve such a quick effect. It works by reducing allergic inflammation which causes the symptoms.
That is why taking more Flonase will not make its effect faster.
Which Allergy Symptoms May Improve First?
Flonase is used for relieving several common symptoms of allergy, which are:
- Sneezing
- Runny nose
- Nasal itching
- Nasal congestion or stuffiness
- Itchy eyes
- Watery eyes
Flonase Allergy Relief is indicated for 24-hour relief of these nasal and ocular allergy symptoms. This fluticasone propionate allergy relief develops gradually with regular use.
You may not feel improvement of all of the symptoms at the same time as sneezing or itching may disappear earlier than congestion.
Congestion may take a bit longer as it may be hard to reduce severe swelling in the nasal passages quickly.
This is also the reason why how quickly does Flonase relieve nasal congestion may have a different answer from the onset of relief for sneezing or itching.
How to Help Flonase Work Effectively
Correct application is especially important if you want to get the desired effect from Flonase. Even if you are using a good medicine, it may seem to you that it does not work as most of the spray goes down your throat.
Before using Flonase, gently blow your nose if needed. Shake the bottle as described in the instructions and prime it if it is necessary for your particular Flonase.
Then:
- Keep your head upright or tilted forward
- Put the nozzle of the spray inside one nostril
- Aim it slightly outward, not towards the center wall of the nose
- Press the spray while breathing in gently
- Do not sniff very hard
- Follow the label instructions
- Clean the spray nozzle as directed.
Flonase should be used according to the label instructions. According to the current U.S. labeling, Flonase should be used only once daily and not more than recommended.
Taking additional doses of Flonase in order to reduce its onset time will not help to reach quicker results, but may increase the risk of side effects.
Why Daily Use Makes a Difference
One of the most common reasons of thinking that Flonase does not work is using it as an occasional decongestant.
You may use Flonase when your nose is blocked and skip its use the next day as you feel a little bit better. Then you may start using it again when your symptoms come back.
Such usage of Flonase will make the effect unpredictable.
Fluticasone propionate shows its best effect when inflammation is controlled constantly. As it was stated in clinical information, the optimal effect is achieved due to regular treatment, scheduled once daily.
If your particular Flonase requires the daily use, then you should follow these directions even after the improvement of your symptoms, unless your doctor or pharmacist suggests otherwise.
What Can Affect How Quickly Flonase Works?
The answer to Flonase how fast does it work may differ for each individual patient.
Several factors may affect the process.
Severity of Your Allergies
Someone who suffers from mild sneezing and itching may notice the effect quicker than someone who has a severely congested nose due to inflammation.
Ongoing Allergen Exposure
If you are continuously exposed to the allergens, such as pollen, dust, mold or animal dander, it is possible that the effect from Flonase will be delayed as your symptoms are still noticeable.
Consistency
If you skip some doses, it may become harder to reach full anti-inflammatory effect.
Nasal Spray Technique
If you apply the spray incorrectly and aim it towards the center wall of your nose, most of the dose will go either down your throat or not reach the intended area of treatment.
Severe Congestion
If you have a severely congested nose, it may be harder for the spray to distribute in your nasal passages.
Individual Response
Patients usually have different responses to medications. Clinical information also acknowledges this fact and states that both the fluticasone nasal spray onset time and the extent of symptom relief may be different in various patients.
Common Mistakes That May Delay Relief
Waiting for the relief after the first application is probably the most common mistake.
Flonase does not provide instant decongestant-type relief.
Other mistakes may include:
- Using Flonase only when symptoms become severe
- Frequently skipping daily doses of Flonase
- Aiming the spray towards the nasal septum
- Sniffing very hard immediately after spraying
- Failure to prime the bottle as required
Stopping using the medicine after one or two days as the symptoms have not disappeared completely;
Taking additional doses of the medicine to increase its effect.
Just give some time for the medicine to work and follow the instructions for your particular product.
What If Flonase Is Not Working After Several Days?
If you used Flonase correctly and regularly for several days, but did not notice any improvement, first check the way you use it.
Make sure that the bottle is properly primed and the medicine produces fine mist. Check that you do not aim the spray towards the nasal septum.
Also, think about your exposure to allergens as the medication may have trouble controlling your symptoms due to it.
If your symptoms still bother you after the proper use of the medicine, consult your pharmacist or healthcare provider. There may be other reasons for your congestion or there may be a need in re-evaluating your allergy treatment.
If your doctor prescribed Flonase as a treatment, the pharmacists at Grant Pharmacy may also help you to understand how to use this medicine properly.
Flonase vs. Antihistamines: Which Works Faster?
Flonase and antihistamines have different actions, so it would be misleading to compare them by speed.
Antihistamines mainly prevent the effect of histamine which is produced during the allergic reactions. Some antihistamine products can start showing its effects quite quickly.
Flonase works by reducing inflammation in the nasal passages. This effect gradually builds up, which is why regular use of Flonase is so important.
But it does not automatically mean that one medicine is better than another. It depends on the symptoms you suffer from, their severity, your medical history, as well as on the medicines.
If you want to use an antihistamine in addition to Flonase, you may ask your pharmacist or doctor whether it is okay for you.
Flonase Allergy Relief vs. Flonase Sensimist
It is also important to pay attention to what exactly you use.
Flonase Allergy Relief is based on fluticasone propionate, while Flonase Sensimist is based on fluticasone furoate. These are related corticosteroid medicines, but they have a different active ingredient and different labeling.
When reading the directions, dosage instructions, age limits or treatment timeline online, make sure that the information relates to your particular product.
Possible Side Effects and Safety Considerations
Most people tolerate nasal fluticasone without serious complications, however, side effects may appear.
Among them, the most common side effects of Flonase may include:
- Nasal dryness
- Mild irritation
- Burning or stinging
- Nosebleeds
If you frequently aim the spray towards the nasal septum, you may increase the risk of nasal irritation. Aiming outward can help you avoid this problem.
Seek medical advice if you experience frequent or persistent nosebleeds, nasal pain, sores in the nose, changes in your vision or if your symptoms continue to worsen.
Current Flonase labeling suggests consulting a doctor about the continued use of this medicine for adults and children older than 12 years in case of usage for more than six months consecutively. Children from 4 to 11 years old may use it for the shortest time possible with consultation of the doctor if necessary.
