Bilastine 20mg & Montelukast 10mg Tablets: Uses, Dosage & Side Effects
Sep 03, 2025
Bilastine and Montelukast Tablet is a prescription medicine commonly used to manage allergic conditions such as allergic rhinitis and seasonal allergies. It combines two effective anti-allergic medicines that work together to relieve symptoms like sneezing, runny nose, nasal congestion, itchy eyes, watery eyes, and skin allergies. By targeting different allergy pathways, this combination provides comprehensive and long-lasting symptom relief while improving daily comfort and quality of life.
What is Bilastine and Montelukast Tablet?
Bilastine and Montelukast Tablet is a combination anti-allergic medicine prescribed for adults and adolescents suffering from allergic disorders. It contains two active ingredients:
- Bilastine – A second-generation antihistamine that blocks histamine receptors responsible for allergy symptoms.
- Montelukast – A leukotriene receptor antagonist that reduces inflammation and allergic reactions caused by leukotrienes.
Together, these medicines help relieve allergy symptoms more effectively than single-drug therapy in many patients. The combination is especially useful for people experiencing persistent allergic rhinitis or allergy symptoms that interfere with daily activities and sleep.
How Does Bilastine and Montelukast Tablet Work?
Allergic reactions occur when the immune system overreacts to allergens such as pollen, dust mites, pet dander, mold, or environmental pollutants.
Bilastine blocks the action of histamine, a chemical released during allergic reactions that causes sneezing, itching, watery eyes, and a runny nose. Because it is a newer-generation antihistamine, it is less likely to cause drowsiness compared to many older allergy medicines.
Montelukast works differently by blocking leukotrienes, inflammatory chemicals that contribute to nasal congestion, airway inflammation, and persistent allergy symptoms. By combining these two mechanisms, Bilastine and Montelukast Tablet provides broader allergy control and longer-lasting symptom relief.

Who Should Take Bilastine and Montelukast Tablet?
Bilastine and Montelukast Tablet is generally recommended for individuals diagnosed with allergic rhinitis or other allergic conditions that require combination therapy. It is particularly beneficial for patients whose symptoms are not adequately controlled with antihistamines alone.
Doctors may prescribe this medicine for adults and adolescents based on individual medical history, allergy severity, and treatment response. It should always be used according to a healthcare professional's advice.
How to Take Bilastine and Montelukast Tablet
Take the tablet exactly as directed by your doctor. Bilastine is often recommended on an empty stomach because food and fruit juices may reduce its absorption, while Montelukast is usually taken once daily. Follow your physician's instructions regarding the best timing for your prescribed combination product.
Swallow the tablet whole with water and avoid crushing or chewing it unless advised otherwise. Taking the medicine consistently at the same time each day helps maintain steady allergy control.
Do not increase the dose or discontinue treatment without consulting your healthcare provider, even if symptoms improve.

Seek immediate medical attention if you experience severe allergic reactions, swelling of the face or throat, breathing difficulty, or unusual mood or behavioral changes while taking Montelukast.
Precautions Before Using Bilastine and Montelukast Tablet
Inform your doctor if you have liver disease, kidney disease, asthma, or a history of mental health conditions before starting treatment.
Montelukast has been associated with rare neuropsychiatric reactions, including mood changes and sleep disturbances. Contact your doctor if you notice unusual behavior, anxiety, depression, or suicidal thoughts.
Avoid alcohol if it increases drowsiness. Inform your healthcare provider about all prescription medicines, herbal supplements, and over-the-counter drugs you are taking to reduce the risk of interactions.
