Common questions about Сингуляр (FAQ)
Q: How soon does Singulair usually start to work?
Official documents indicate that the active substance, Montelukast, is rapidly absorbed, reaching maximum concentration in the blood within two to four hours after administration. Clinical studies have shown measured improvements in breathing function (FEV1) within one day of starting the medication for asthma. The long-term therapeutic effect is associated with continuous daily administration, as described in official documents.
Q: Should Singulair be taken continuously or only during flare-ups?
Singulair is officially designated for the long-term maintenance treatment of chronic conditions, such as asthma and allergic rhinitis. For these purposes, official product information describes that it is administered daily, as it is not intended for use in managing acute attacks or sudden symptom flare-ups.
Q: What's the difference between Singulair and other allergy medicines?
Singulair belongs to the pharmacological class known as a leukotriene receptor antagonist. Its mechanism of action works by blocking the effects of specific inflammatory chemicals called leukotrienes. This mechanism is chemically distinct from other common allergy treatments, such as antihistamines.
Q: Can Singulair be taken with other cold medicines?
Official drug interaction data for Singulair do not list common over-the-counter cold medicine ingredients as having a known interaction. However, because the full data on every possible combination may be unknown, regulatory documents describe the importance of disclosing all medications, including non-prescription remedies like cold medicines, to a healthcare provider.
Q: Does Singulair cause drowsiness?
According to official regulatory documents, drowsiness is listed as an uncommon adverse reaction that has been reported during the use of Singulair. Patients should observe how the medicine affects them.
Q: How long can Singulair be taken without a break?
Singulair has been examined in clinical studies for the long-term management of asthma and allergic rhinitis, with some data collected over periods of one year. The duration of administration is typically established by a healthcare provider, taking into account the patient's condition.
Q: Why is Singulair taken in the evening?
For the management of chronic asthma, the official administration instructions state that the dose is administered once daily in the evening. This timing is generally advised because asthma symptoms often worsen during the nighttime and early morning hours. For allergic rhinitis, the time of administration may sometimes be adjusted based on individual patient needs.
Q: Can Singulair affect body weight or appetite?
Changes in body weight or appetite are not listed in the official regulatory documents as commonly or uncommonly reported side effects. Concerns regarding changes in weight or appetite while on this medication are typically reviewed by a healthcare provider.
Q: Are there generics (analogs) of Singulair with the same active substance?
Yes, the active drug in Singulair is Montelukast sodium. Official drug registries confirm the existence of multiple generic versions (analogues) that contain the exact same active substance, as Singulair is the original brand name.
Q: Can Singulair interact with herbal supplements?
Singulair’s concentration in the body can be affected by substances that influence certain liver enzymes, known as CYP450. While specific herbal supplements are not detailed in official drug interaction lists, regulatory documents generally emphasize the importance of disclosing the use of all supplements and herbal remedies to a healthcare provider.
Q: What should I do if I miss a dose of Singulair?
Official prescribing information describes that if a dose is missed, administration of the next dose occurs at the usual scheduled time. There are no regulatory instructions to take two doses or double the next dose to make up for a missed dose.
Q: Can I drink alcohol while taking Singulair?
Official documents do not contain a direct prohibition against consuming alcohol while taking Singulair. However, given that rare, serious adverse events like hepatitis (liver injury) are documented, questions regarding alcohol consumption while taking this medication are typically directed to a prescribing physician.
Q: Are children allowed to take Singulair, and from what age?
Eligibility for Singulair is determined by the child's age and the specific condition being treated. For chronic asthma, the medicine is approved for children as young as 12 months; for seasonal allergic rhinitis, it is approved from 2 years; and for perennial allergic rhinitis, it is approved from 6 months of age.
Q: Is Singulair used to treat only seasonal or perennial allergy?
According to the official therapeutic indications, Singulair can be used for the treatment of symptoms associated with both seasonal and perennial (year-round) allergic rhinitis, subject to the appropriate age requirements for each indication.
Q: Can I become addicted to Singulair?
Regulatory documents do not classify Montelukast as a substance that causes physical dependence or addiction. Information on drug abuse and dependence typically indicates that there is no known risk of forming an addiction to this medication.
Q: What happens if I suddenly stop taking Singulair?
Official warnings state that Singulair must not be abruptly discontinued or used to replace inhaled or oral corticosteroids. The decision to discontinue administration, especially if neuropsychiatric symptoms are present, involves consultation with a healthcare professional.
Q: Should I take Singulair during an asthma attack?
No. Singulair is not indicated for the treatment of an acute asthma attack. The medication is for long-term maintenance control only. Rescue medication is typically kept available for use during an acute episode.
Q: Why do doctors prescribe Singulair instead of inhalers?
Official documents state that for allergic rhinitis, Singulair is generally reserved for patients who have had an inadequate response to or an inability to tolerate alternative first-line therapies. This indication suggests the drug may be reserved for use when alternative approaches are inadequate or not tolerated.
Q: What information about Singulair is available in official regulatory sources?
Official regulatory sources, such as the U.S. FDA and the European Medicines Agency (EMA), provide comprehensive information on the medicine. This includes details on indications, dosing, contraindications, safety warnings (including the Boxed Warning for neuropsychiatric events), drug interactions, and clinical study data.
Q: Can I take Singulair if I have kidney problems?
The official prescribing information notes that no dose adjustment for Singulair is required for patients with impaired kidney function. Prescribing decisions are typically made by a physician who considers all co-existing health conditions.

Q: Can Singulair be taken in the summer for prevention?
