Montair LC dosage: how to take it

How to take Montair LC

Take Montair LC exactly as your doctor advises or as printed on the pack. Do not take more than one tablet a day or use it for longer than your doctor recommends.

• It is usually taken once a day, often in the evening. Take it at about the same time each day.
• It can be taken with or without food. Swallow the tablet whole with water.
• Do not take it together with other medicines that contain montelukast, levocetirizine, cetirizine or another antihistamine, including some cold and cough remedies. Check the labels of combination products.
• Montair LC does not relieve a sudden asthma attack. If you have asthma, keep using the inhalers your doctor has prescribed.
• If you miss a dose, skip it and take the next dose at the usual time. Do not take two doses to make up for it.
• The Montair LC tablet is meant for adults and adolescents aged 15 and over. Products for children contain lower strengths and should be given only on a doctor's advice.
• Your doctor decides how long you need it. For seasonal allergy, this may be only during the pollen season.

Who should be careful

Montair LC is not suitable for everyone. Tell your doctor before taking it if any of the following apply to you.

• Depression, anxiety or any other mental health condition, now or in the past. Mood and behaviour changes have been reported with montelukast in people with and without such a history
• Asthma: Montair LC does not relieve an asthma attack, and inhaled or oral steroids should not be stopped or reduced unless a doctor says so
• Asthma that gets worse with aspirin or other painkillers: you still need to avoid those painkillers
• Kidney disease: levocetirizine builds up when the kidneys work poorly, and the medicine is not suitable for people with severe kidney failure
• Severe liver disease
• Epilepsy or a history of fits
• An enlarged prostate, a spinal cord problem or another condition that makes it hard to pass urine
• Allergy to cetirizine, hydroxyzine or similar antihistamines
• Pregnancy and breastfeeding: information is limited. Use it only if a doctor advises it
• Driving or using machines: it can make you sleepy or dizzy. Do not drive until you know how it affects you
• Allergy skin tests: antihistamines can affect the results, so tell the doctor; they are usually stopped a few days before the test
• Children: the Montair LC tablet is not meant for children under 15

Medicines and things that interact with Montair LC

Montair LC can interact with some medicines and with alcohol. Tell your doctor or pharmacist about everything you take, including cough, cold and allergy medicines bought without a prescription.

• Alcohol, sleeping pills, anxiety medicines, strong painkillers and other medicines that cause drowsiness: more sleepiness and slower reactions
• Other antihistamines, including cetirizine, chlorphenamine and those in cold remedies: more side effects such as sleepiness and dry mouth
• Phenobarbital, phenytoin and rifampicin: can lower the level of montelukast, so it may work less well
• Gemfibrozil (for cholesterol): can raise the level of montelukast
• Ritonavir (an HIV medicine) and theophylline (for asthma): can raise the level of the antihistamine part
