Allergies in India are becoming more common due to rising pollution, dust exposure, and weather changes. From sneezing fits in the morning to itchy eyes during the day, allergic rhinitis and seasonal allergies can be exhausting. While there are many over-the-counter allergy medicine options, one combination that’s getting attention is Montelukast and Fexofenadine. Let’s break down why this combo is used, how it works, and what you should know before taking it.
What Are Montelukast and Fexofenadine?
Montelukast is a leukotriene receptor antagonist. It blocks substances in the body called leukotrienes, which cause swelling, tightening of airway muscles, and other allergy symptoms. Montelukast is often prescribed in India for asthma, allergic rhinitis, and seasonal allergy treatment.
Fexofenadine is a second-generation antihistamine. It blocks histamines, the chemicals responsible for sneezing, runny nose, and itching. It’s a non-drowsy allergy tablet, which makes it safer to take during the day without affecting your alertness.
Used together, this antihistamine and leukotriene combo provides more complete relief from allergy symptoms than either medicine alone.
Why Is This Combination Effective?
Here’s the thing: Most allergy medicines target only one pathway of the allergic reaction. Fexofenadine handles histamines. Montelukast blocks leukotrienes. But allergies usually involve both. So using both medicines targets the root of the reaction in two different ways.
This combination is particularly useful for people with allergic rhinitis, hay fever, or persistent nasal congestion. It’s also helpful for patients with asthma triggered by allergies.
Montelukast and Fexofenadine benefits include:
- Reduced sneezing, runny nose, and nasal congestion
- Relief from itchy or watery eyes
- Better breathing for people with mild asthma
- Fewer night-time symptoms that interrupt sleep
- Non-drowsy daytime use
- Improved quality of life during allergy season
Who Should Consider This Combo?
If you’ve tried single-drug therapy for allergies with limited success, your doctor might suggest this combo. It’s usually given to:
- People with seasonal allergic rhinitis that doesn’t improve with antihistamines alone
- Those with both asthma and allergies
- Patients looking for a non-drowsy solution to allergy symptoms
- Children (under doctor supervision) who struggle with allergy-related breathing issues
It’s one of the most prescribed allergy relief medicines in India, especially in urban areas where pollen, dust mites, and pollution trigger reactions year-round.
Dosage and Use in India
Doctors in India usually prescribe Montelukast in a 10 mg dose and Fexofenadine in a 120 mg or 180 mg dose, once a day, usually in the evening. Children may receive smaller doses depending on their age and weight.
It’s essential to follow your doctor’s instructions and not self-medicate, especially for children. These drugs may not be suitable for everyone.
Are There Any Side Effects?
Like any medication, Montelukast and Fexofenadine combo can have side effects, but most are mild and temporary.
Common side effects may include:
- Headache
- Dry mouth
- Drowsiness (rare with Fexofenadine)
- Abdominal discomfort
- Mood changes (rare, mostly associated with Montelukast)
If you experience sleep disturbances, anxiety, or unusual behaviour, contact your doctor right away. While rare, some patients have reported such effects with Montelukast use in India.
Over-the-Counter vs Prescription
In some countries, Fexofenadine is available over the counter. However, in India, the Montelukast Fexofenadine combination is typically prescription-only. This is because doctors need to evaluate your health status, history of asthma or other respiratory issues, and allergy triggers before suggesting the right dosage.
Don’t mix or switch between allergy tablets without medical advice. Even non-drowsy allergy tablets can interfere with other medicines or health conditions.
Can Children Take This Combo?
Yes, but only under pediatric supervision. Pediatricians often recommend this combo for kids who suffer from seasonal allergies or mild asthma. The fexofenadine dosage in India for children is lower and carefully adjusted.
Never give adult-strength tablets to children. Choose chewable or liquid versions if prescribed.
How Long Should You Take It?
This combo can be used short-term during allergy season or as a part of a long-term plan if allergies or asthma are ongoing. Your doctor will decide how long you should continue.
Stopping the medication abruptly, especially in patients with asthma, may lead to a flare-up. Follow-up appointments are essential to adjust the treatment plan if needed.
Why This Combo Is Becoming More Popular in India
- Rising air pollution makes allergic rhinitis a year-round issue
- Urban patients are looking for non-drowsy, effective allergy solutions
- Doctors find better symptom control when both histamines and leukotrienes are blocked
- Safe usage over time has made this a go-to prescription in many cities
Patients often report fewer sick days, improved sleep, and reduced reliance on nasal sprays or inhalers.
