If you are like me and many others worldwide suffering from seasonal allergies, you know the struggle to get through the day, never mind getting a workout in.

I’m always on the lookout for the best way to get relief so I can get back into my routine. That is why when I heard a talk at the gym about how great Telekast F is for allergies, I had to do some research.

With the help of our medical professional and after several hours of online research, I have compiled great information. Check it out.

What is Telekast F?

Telekast F is a medication that is a combination of Montelukast and Fexofenadine used to treat allergy symptoms like sneezing, cough, runny nose, itchy or watery eyes, and urticaria (hives).

Telekast F is a tablet you can take with or without food, and you should use it as directed by your doctor.

How It Works

Montelukast, commonly known by the brand name Singulair, is a leukotriene receptor antagonist drug that blocks the body from producing leukotriene, lessening allergy symptoms [2].

Leukotrienes cause airway tightening and mucus production. These inflammatory chemicals are major players in allergies, allergic rhinitis, and asthma.

Fexofenadine, known as Allegra, is an antihistamine [3]. Histamines are chemicals produced by your immune system whose job is to help your body get rid of something, in this case, an allergen [4].

“Inflammation that triggers symptoms of asthmatic bronchitis might occur in someone who has underlying asthma after exposure to certain substances, such as pollen, pollution, and cigarette smoke. People with asthmatic bronchitis respond to these environmental triggers by releasing leukotrienes. These are inflammatory molecules. Leukotrienes cause a series of reactions, including narrowing of the airway.”

Telekast F is a treatment for asthma, allergies, allergic rhinitis, and athletic-induced asthma.

According to my research, Telekast F is most effective for treating asthma and allergies when used regularly, even if symptoms subside.

When using for sport-induced asthma, taking a couple of hours before an aerobic exercise will ensure it is at its peak during exercise.

Benefits of Telekast F
