Flonase

Flonase is an over-the-counter nasal spray. It contains fluticasone propionate. The 50mcg spray relieves nasal allergy symptoms. It reduces inflammation inside the nose. Flonase is available without a doctor’s order. It is sold at pharmacies and grocery stores across the United States.

Unlike oral antihistamines, Flonase works locally. It does not cause drowsiness. It blocks multiple allergic triggers. Pollen, dust, pet dander and mold. Full relief builds over 3 to 7 days. It is not for immediate relief. Consumers buying Flonase online should verify the 50mcg strength and spray count.

What Is Flonase

Flonase contains fluticasone propionate. It is a corticosteroid nasal spray. It belongs to the glucocorticoid class. It reduces inflammation in nasal passages. It also reduces mucus production. The 50mcg spray delivers a measured dose per pump.

Flonase is approved for seasonal and year-round allergies. It helps with nasal congestion, runny nose, sneezing and itchy eyes. It does not cure allergies. It controls symptoms. The OTC version uses the same formula as the former prescription version. The FDA approved OTC status in 2014.

How Flonase Works

Fluticasone binds to glucocorticoid receptors in nasal tissue. This blocks the release of inflammatory chemicals. Histamine, prostaglandins and leukotrienes. These chemicals cause swelling, itching and mucus.

Key mechanisms:

• Anti-inflammatory: Reduces swelling of nasal passages within 8 to 24 hours.
• Mucus reduction: Decreases production of nasal discharge.
• Histamine blockade: Prevents histamine release from mast cells.
• Multi-trigger coverage: Works against pollen, dust, mold and pet dander.

Conditions Relieved by Flonase

Flonase helps control nasal allergy symptoms. It is not for colds or sinus infections. It is for allergic rhinitis only.

Flonase helps with:

• Seasonal allergies: Pollen from trees, grass and weeds.
• Year-round allergies: Dust mites, pet dander and indoor mold.
• Nasal congestion: Stuffy nose from inflammation.
• Runny nose and sneezing: Excess mucus and irritation.
• Itchy nose and eyes: Allergic irritation.

Flonase is not for:

• Common cold relief
• Acute sinus infections
• Nasal polyps (requires medical evaluation)
• Children under 4 years

Flonase Dosage and Strengths

Available Forms

Flonase comes in several delivery forms. All contain fluticasone propionate.

• Flonase 50mcg nasal spray: Standard OTC pump. 120 sprays per bottle. One spray per nostril daily.
• Flonase Sensimist: Fine mist spray. 27.5mcg per spray. Gentler delivery. Same active ingredient.
• Flonase Children’s: 50mcg spray. For ages 4 to 11. Lower recommended dose.
• Generic fluticasone 50mcg: Same active ingredient. Lower cost. Same dosing.

Standard Adult Dosing

Start with 2 sprays in each nostril once daily. This equals 200mcg total. After symptoms improve, reduce to 1 spray per nostril. This equals 100mcg total. Do not exceed 2 sprays per nostril per day. Higher doses increase side effect risk.

Shake the bottle gently before use. Prime the pump if new or unused for 7 days. Aim slightly away from the nasal septum. Sniff gently. Do not inhale forcefully. Forceful inhalation drives medication into the throat. This reduces effectiveness and increases side effects.

Missed Dose Instructions

Use the missed dose when you remember. Skip it if the next dose is within 6 hours. Do not double the dose. Doubling increases nasal irritation and bleeding risk. Resume the normal schedule.

Flonase vs Nasacort vs Claritin

Flonase, Nasacort and Claritin all relieve allergy symptoms. They work differently. Flonase is a corticosteroid nasal spray. Nasacort is also a nasal steroid. Claritin is an oral antihistamine.

Choose Flonase for nasal congestion and multi-symptom relief. It blocks all major allergy chemicals. Choose Nasacort if Flonase causes nosebleeds. Nasacort uses triamcinolone. It is slightly gentler on nasal tissue. Choose Claritin for sneezing and itching without nasal spray. It does not relieve congestion. It is faster acting but less comprehensive.

Do not combine two nasal steroids. Do not use Flonase and Nasacort together. This increases side effects. You may combine Flonase with Claritin for severe days. This is safe for short periods.

Side Effects

Common Side Effects

Most users tolerate Flonase well. Mild effects usually resolve within 1 week:

• Nasal irritation or dryness
• Nosebleeds (epistaxis)
• Sore throat
• Headache
• Unpleasant taste or smell
• Cough

Serious Side Effects

Stop using Flonase and contact a doctor if you experience:

• Severe nosebleeds that do not stop
• Perforation of the nasal septum

Who Should Not Use Flonase

Do not use Flonase if you have recent nasal surgery or injury. Do not use if you have untreated nasal infections. Do not use if you are allergic to fluticasone propionate. Do not use for children under 4 years.

Consult a doctor before use if you have glaucoma or cataracts. Steroids may worsen eye pressure. Use caution if you have tuberculosis or untreated infections. Steroids suppress local immune response.

Warnings and Precautions

Flonase takes 3 to 7 days to reach full effect. Do not expect immediate relief. For sudden symptoms, use an oral antihistamine. Continue Flonase daily during allergy season. Stopping early allows symptoms to return.

Aim the spray away from the nasal septum. This reduces nosebleeds. Do not share your bottle. Sharing spreads infection. Clean the spray nozzle weekly. Rinse with warm water and dry.

Long-term use at high doses may cause systemic steroid effects. These are rare with nasal spray. They include adrenal suppression and growth delay in children. Use the lowest effective dose.

Drug Interactions

Flonase has minimal systemic absorption. Interactions are rare. However, caution applies with:

• Other nasal steroids: Do not combine. Increases local side effects.
• Ketoconazole: May increase fluticasone blood levels slightly.
• Ritonavir: Significantly increases fluticasone levels. Avoid combination.
• Other corticosteroids: Combined use increases systemic exposure.

Flonase and Pregnancy

Flonase is Category C during pregnancy. Use only if benefits outweigh risks. The lowest effective dose is recommended. Fluticasone passes into breast milk in small amounts. It is generally considered safe during breastfeeding. Consult your obstetrician before use.

Overdose Information

Nasal spray overdose is unlikely. Symptoms of excessive use include nasal irritation, nosebleeds and headache. Systemic overdose is rare. Symptoms include fatigue, weight gain and mood changes. Rinse nose with saline if you apply too much. Contact poison control if a child swallows the contents.
