Flonase vs Claritin – Uses, Side Effects, Differences


It is a nasal spray that contains a medication called fluticasone that belongs to a class of drugs called corticosteroids. It helps prevent the release of substances in the human body which causes inflammation.

Its effects develop within 2 to 4 hours after intranasal administration. It is an over-the-counter (OTC) drug, therefore, you don’t need a prescription.


This corticosteroid can be used to relieve seasonal and year-round allergic and non-allergic nasal symptoms, like – stuffy and runny nose, sneezing, and itching.


For adults and adolescents, the usual recommended dose is 2 sprays in each nostril once a day. After seven days of treatment, the dose may be reduced to 1 spray into each nostril once per day. However, if 1 spray into each nostril does not control the symptoms properly, you should return to 2 sprays in each nostril once per day.

This nasal spray needs to be regularly used in order to work at maximum efficiency. On average, it needs a few days for you to get the full benefit of the nasal spray.

Note – before the first use or after a period of non-use (seven days or more), you need to prime the pump. This medicine can be used in adults and children who are at least 4 years old.

Flonase vs Claritin – Which Is More Effective?

Flonase is utilized to cure nasal congestion, runny nose, sneezing, as well as watery or scratchy vision caused by regular or year-round allergies.

Claritin contains the medication called loratadine which belongs to a group of drugs known as antihistamines. Loratadine reduces the effect of a natural chemical in the body called histamine that is responsible for many of the symptoms caused by regular or year-round allergies.

According to studies, loratadine is more efficient and has fewer side effects than fluticasone. However, the real problem is that both have plenty of side effects and don’t cure allergies.

5 Natural Allergy Relief Remedies

#1 Saline Water

Regular nasal saline irrigation can help to reduce and prevent the symptoms of allergic rhinitis. Also, they can help improve the function of cilia which helps clear the sinuses.

Sinus infections typically occur when swelling from allergens, irritants, viruses, or bacteria causes blockage of the opening of the sinuses.

#2 Nettle Infusion

A nettle infusion has potent anti-inflammatory and antihistamine attributes to relieve allergic rhinitis.

This is due to the high content of active compounds, like – chlorophyll A and B, flavonoids, organic acids, tannins, carotenoids, and amine compounds that are found in this plant.

#3 Steam Inhalation

Inhaling steam is considered one of the most effective natural treatments for allergic rhinitis. Moreover, when essential oils and steam are combined, they form an even better method to treat allergic rhinitis.

#4 Ginger

Due to its powerful anti-inflammatory, immune-boosting, antiviral, and antibacterial characteristics, ginger is considered one of the most effective remedies for allergic rhinitis and its symptoms, like – a runny nose, a cough, or nasal congestion.

#5 Nutrition

Try to avoid foods that cause inflammation in the body, like – meats, dairy products, alcoholic beverages, and foods that contain food additives.

Instead, focus on spinach, kale, Swiss chard, collard greens, watercress, blueberries, sweet potatoes, broccoli, red cabbage, garlic, ginger, turmeric, cinnamon, onions, apple, papayas, pineapples, mangoes, cauliflower, which are all a great source of essential minerals, vitamins, and antioxidants that help reduce inflammation.
