Montelukast is a prescription medication used for asthma treatment. This is manufactured by the brand Accord, and belongs to a type of asthma medicine known as leukotriene receptor antagonist. This works to prevent the lungs from reacting to leukotriene, a natural compound that becomes aggravated by triggers which lead to asthma-related symptoms. Other uses of Montelukast include prevention of exercise-induced bronchoconstriction; relieve hay fever and other allergies. The potency and dosage must be kept according to your physician’s prescription. Any misuse of the drug can have potentially harmful effects on the body and your health.

What are Montelukast Tablets

Montelukast tablets are a prescription medication used for asthma treatment. Other uses of Montelukast include prevention of exercise-induced bronchoconstriction; relieve hay fever and other allergies. Montelukast may be used with other medications as a combination therapy prescribed by your doctor.

How Does Montelukast Work?

Montelukast is from a class of drugs known as leukotriene receptor antagonists, which are used to decrease inflammation and nasal congestion. These drugs keep the airways to the lungs open to prevent reactions of conditions such as asthma and seasonal or year-round allergies. They are also used to prevent breathing problems caused by strenuous activities such as exercising.

What Are the Benefits of Taking Montelukast Tablets?

Some benefits of Montelukast include:

  • Exercise induced bronchoconstriction occurs when lung airways narrow due to exercise, causing coughing, wheezing and shortness of breath. Montelukast can be used to prevent this from happening.
  • Prevents and controls asthma symptoms.
  • May decrease the frequency of usage of quick-relief inhalers.
  • Provides relief in hay fever, seasonal and year-round allergies.

How to Use Montelukast Tablets?

Montelukast asthma medication needs to be taken orally, preferably at the same time every day. It can be taken with or without food as directed by your physician. The dosage prescribed is based on age, medical condition and many other factors considered by your doctor.

Montelukast comes in two forms: chewable tablets and normal ones. In case you are taking the chewable form, you must chew them thoroughly before swallowing. Chewable tablets should not be swallowed whole.

If Montelukast has been prescribed for your asthma or both asthma and allergies, take your dose in the evening. If you are only taking it for allergies, you may take it either in the morning or the evening. Montelukast may be prescribed for breathing problems during and after exercise. In this case, take the tablet at least 2 hours before exercising. However, do not double dose if you have already taken the tablet for your asthma or allergy.

The intake should not be stopped without the recommendation of your doctor. The tablets are used to keep asthma under control and work over time. The effects of the medication show up after regular use and it is not for relieving sudden asthma attacks. You will still need your quick-relief inhaler in case of sudden asthma attacks or breathing problems.

What dosage of Montelukast Tablets is advisable?

Montelukast comes in different strengths including 4mg, 5mg, and 10 mg tablets. The typical dosage for adults is one 10 mg tablet a day to be taken in the evening. For children, the dosages might vary. The typical dose for children ages 6-14 years is one 10 mg chewable tablet a day and for ages 2-5 years is one 4 mg chewable tablet a day.

The dosage information will be given to you by your doctor depending on your age, medical condition and severity of the condition. Ensure to take the medicine exactly as prescribed to prevent side effects.
