Montelukast

Anti-allergy and asthma preventer

What it is used for

Prevents asthma attacks and reduces allergic nose symptoms.

How it works

It blocks leukotrienes, chemicals that narrow the airways and cause allergic swelling. It prevents asthma symptoms but does not relieve an attack.

How to take it

Adults take 10 mg once a day in the evening; children get 4 or 5 mg chewables or granules. Keep taking it even when well, and keep a reliever inhaler for attacks.

Common side effects

  • Headache
  • Stomach pain
  • Diarrhoea
  • Upper respiratory infection

Get medical help straight away if

  • Mood or behaviour changes, bad dreams, agitation, depression or suicidal thoughts (stop and tell your doctor)
  • Pins and needles with rash (rare vasculitis)

Be careful

Can rarely cause mood changes or bad dreams; tell your doctor if this happens.

Other medicines and interactions

Phenobarbital and rifampicin can lower its level. Otherwise few interactions.

Pregnancy and breastfeeding

May be continued in pregnancy if it controls asthma well; uncontrolled asthma is a bigger risk. Ask your doctor about breastfeeding.

Fexofenadine

Antihistamine (non-drowsy)

What it is used for

Relieves seasonal allergies (sneezing, runny nose, itchy eyes) and hives.

How it works

A non-drowsy antihistamine that does not enter the brain much, so it rarely causes sleepiness.

How to take it

Adults: 120 mg once a day for hay fever, 180 mg for hives. Take with water, not fruit juice, and not within 2 hours of an antacid.

Common side effects

  • Headache

Allergic reaction

Be careful

Do not take with fruit juices or antacids close together; they reduce its effect.

Other medicines and interactions

Pregnancy and breastfeeding
