Q: What is Montelukast used for?

Montelukast is used to treat: Asthma Allergic rhinitis Exercise-induced bronchoconstriction

Q: How does Montelukast work?

Blocking Leukotrienes Montelukast works by interfering with substances in the body called leukotrienes. These are chemicals that the immune system releases when a person breathes in an allergen, such as pollen, or during physical exertion. In people with asthma or allergies, leukotrienes cause several physical reactions: Airway tightening: They cause the muscles around the airways to squeeze shut, making it harder to breathe. Inflammation: They lead to swelling and irritation in the lining of the lungs and nasal passages. Mucus production: They trigger the body to produce more fluid and mucus, contributing to congestion and a runny nose. Preventing Symptoms By blocking the action of these chemicals, montelukast helps to keep the airways open and reduces inflammation. This action helps prevent the symptoms of asthma, such as coughing and wheezing, and relieves the symptoms of seasonal or year-round allergies, such as sneezing and itchy eyes. It is important to note that montelukast is a preventive medication. It works over time to manage the body's response to triggers and is not intended to stop an asthma attack that has already started.

Q: Is Montelukast safe during pregnancy and breastfeeding?

Pregnancy Available data from studies in pregnant women have not identified a clear drug-associated risk of major birth defects or miscarriage. Research in animals using doses much higher than the standard human dose has not shown evidence of harm to the fetus. However, because animal studies are not always predictive of human response, montelukast should be used during pregnancy only if the potential benefit justifies the potential risk. If you are pregnant or planning to become pregnant, you should discuss the risks and benefits of continuing or starting this medication with your healthcare provider. Breastfeeding Montelukast is known to be excreted in human breast milk. There is currently no information available regarding the effects of the drug on milk production or its impact on the nursing infant. Because many drugs are present in human milk, healthcare providers recommend exercising caution when using montelukast while breastfeeding. It is important to consult with a healthcare professional to determine the best course of action for your specific situation.

What is the FDA approval status of Montelukast?

Accepted Answer

FDA Approval and Indications

Montelukast is approved by the U.S. Food and Drug Administration (FDA) for the following indications:

Asthma: Chronic treatment and prevention of asthma in adults and children 12 months of age and older.
Exercise-Induced Bronchoconstriction: Prevention of exercise-induced bronchoconstriction (EIB) in patients 6 years of age and older.
Allergic Rhinitis: Relief of symptoms for seasonal allergic rhinitis in patients 2 years and older, and perennial allergic rhinitis in patients 6 months and older.

Boxed Warning

In March 2020, the FDA required a Boxed Warning for montelukast, which is the agency's most serious type of warning. This warning was added because the drug is associated with serious neuropsychiatric events, including suicidal thoughts or actions. Other reported mental health side effects include agitation, aggression, depression, sleep disturbances, and hallucinations.

Regulatory Guidance for Use

Due to the risk of mental health side effects, the FDA advises that for allergic rhinitis, montelukast should be reserved for patients who have not responded adequately to other treatments, such as antihistamines or nasal steroids, or for those who cannot tolerate these alternative therapies. Healthcare providers are instructed to monitor all patients taking montelukast for any changes in behavior or mood.

Question 12

What should I know about Montelukast and withdrawal?

Accepted Answer

Discontinuing Montelukast

Montelukast is a maintenance medication used for the long-term control of asthma and the management of allergic rhinitis. It is not a controlled substance and is not known to cause physical dependence or a clinical withdrawal syndrome when stopped.

Return of Symptoms

The main risk of stopping montelukast is that the symptoms it was treating may return or worsen. Because the drug works by blocking leukotrienes to prevent inflammation and airway constriction, discontinuing it may lead to:

Increased asthma symptoms, such as coughing, wheezing, or shortness of breath.
A return of seasonal or year-round allergy symptoms.
A higher risk of exercise-induced breathing difficulties.

Medical Guidance

It is important to continue taking montelukast exactly as directed by a healthcare provider, even during periods when you feel well and have no symptoms. You should not stop taking this medication without consulting your doctor first. They will help you determine if your asthma or allergies are stable enough to discontinue treatment and may provide an alternative management plan to prevent a relapse of symptoms.
