Take Montek BL on an empty stomach — ideally at least 1 hour before or 2 hours after eating — because bilastine’s absorption is reduced by food, while montelukast can be taken with or without food.

💊 How to take Montek BL

• Take once daily as your doctor prescribes; the tablet contains bilastine 20 mg (milligram) + montelukast 10 mg (milligram).
• Timing: take the dose ≥1 hour before or ≥2 hours after a meal to optimize bilastine absorption.
• Avoid antacids containing magnesium/aluminium within 2 hours of the tablet.
• If your prescriber specifically advised a night dose (common for montelukast in some patients), follow that instruction.

⚠️ Warnings

• Stop and seek medical attention for new or worsening mood changes, depression, or suicidal thoughts.
• Seek urgent care for allergic reaction signs (hives, facial/throat swelling, difficulty breathing) or extreme drowsiness.
• Consult a doctor before use if you have liver or kidney impairment, are pregnant or breastfeeding, or the patient is under 12 years.

🩺 When to see a doctor

• Discuss use and exact timing with an allergist or an ENT (ear, nose and throat) doctor if you have the conditions noted above or any doubts.
• Follow-up question: Do you have liver/kidney disease, are pregnant or breastfeeding, under 12 years old, or currently taking antacids?
