Singulair (Montelukast) Buyer and Patient Handbook in Singapore
Singulair (Montelukast) is a leukotriene-receptor antagonist indicated for the treatment of Asthma and the relief of Allergic Rhinitis symptoms. It belongs to the class of leukotriene modifiers and is available as a small oral tablet.
What is Singulair?
Singulair is a tablet that blocks leukotrienes-chemicals released during an allergic response that cause airway narrowing and inflammation. It is approved by the Health Sciences Authority (HSA) of Singapore for:
- Asthma control (including exercise-induced bronchoconstriction)
- Allergic rhinitis (seasonal and perennial)
- Prevention of chronic airway inflammation
The drug is marketed worldwide under the brand name Singulair, while the generic name is montelukast.
Who Should Use Singulair?
- Adults and adolescents (12 years +) with persistent asthma who need additional control beyond inhaled corticosteroids.
- Children 5 - 11 years for asthma or allergic rhinitis (dose adjusted by weight).
- Individuals who experience exercise-induced bronchospasm.
- Patients who prefer an oral tablet over inhaler therapy for mild-to-moderate symptoms.
How Does It Work?
Montelukast binds to cysteinyl-leukotriene-1 (CysLT₁) receptors on airway smooth muscle and inflammatory cells, preventing leukotrienes from triggering bronchoconstriction and mucus production. Think of it as installing a “stop-sign” at the traffic lights that normally let inflammation rush through. By dampening this pathway, the medication reduces wheezing, coughing, and nasal congestion.
Safety note: Montelukast has a low potential for abuse and is not a controlled substance.
Why Choose Singulair?
- Convenient oral dosing eliminates the need for inhaler technique training.
- Proven efficacy in both asthma control and seasonal allergy relief, supported by extensive clinical data.
- Generic availability (montelukast tablets) offers a cost-effective alternative with identical bio-equivalence.
Off-label uses-such as treating certain dermatologic conditions-should only be considered after professional advice.
Dosage, Administration, Lifestyle and Dietary Recommendations
Recommended Dosage
| Strength | Typical Dose (once daily) | Age / Indication |
|---|---|---|
| 4 mg | 4 mg | Children 5-14 kg (asthma, allergic rhinitis) |
| 5 mg | 5 mg | Children 15-30 kg (asthma, allergic rhinitis) |
| 10 mg | 10 mg | Adults ≥ 15 kg and children > 30 kg (asthma, allergic rhinitis, exercise-induced bronchospasm) |
How to Take
- Take once daily in the evening for asthma; morning dosing is acceptable for allergic rhinitis.
- Swallow the tablet whole with a glass of water; food does not affect absorption.
- If you miss a dose, take it as soon as you remember unless it is near the time of the next scheduled dose-then skip the missed tablet and continue with the regular schedule.
Missed Dose
- Do not double-dose. Taking two tablets at once can increase the risk of side effects.
Overdose
- If an overdose is suspected, seek immediate medical attention or contact Singapore’s National Poison Centre (180-225 5555). Typical symptoms include severe headache, Drowsiness, or Nausea.
Special Populations
- Elderly: No dosage adjustment required; monitor for neuropsychiatric changes.
- Renal/hepatic impairment: No routine dose change, but monitor clinical response.
- Pregnancy & lactation: Category B; generally considered safe, but discuss with a healthcare professional.
Lifestyle & Diet
- Grapefruit juice does not interact with montelukast.
- Alcohol does not affect efficacy, but excessive intake may worsen asthma symptoms.
- Maintain regular exercise; singulair is effective for preventing exercise-induced bronchospasm when taken at least 2 hours before activity.
Precautions and Warnings
- Neuropsychiatric effects: Mood changes, Depression, or suicidal thoughts have been reported; report any new psychological symptoms promptly.
- Allergic reactions: Rash, angioedema, or Anaphylaxis require urgent medical care.
- Hepatic dysfunction: Rare liver enzyme elevations-monitor if pre-existing liver disease exists.
Drug Interactions
| Drug Class | Interaction Risk | Management |
|---|---|---|
| Rifampin (enzyme inducer) | ↓ Montelukast levels | Monitor asthma control; consider alternative |
| Phenobarbital | ↓ Montelukast levels | Same as above |
| Protease inhibitors (e.g., ritonavir) | ↑ Montelukast levels | No dose change usually needed, observe for side effects |
Only a few clinically significant interactions are known; always inform your healthcare provider of all medicines you take.

Frequently Asked Questions
How quickly does Singulair start working for asthma?
It begins to reduce airway inflammation within a few hours, but full effect may take several days of regular use. Consistency is essential for optimal control.
Can I use Singulair with my inhaled rescue inhaler?
Yes, Singulair is meant to be an add-on controller and does not replace a short-acting bronchodilator for acute symptoms.
Is Singulair safe for people with hypertension?
There is no direct interaction; however, any new medication should be discussed with a clinician if you have cardiovascular concerns.
Will Singulair cure my allergies?
No, it alleviates symptoms by blocking leukotrienes but does not eliminate the underlying allergic response. Continued avoidance of triggers remains important.
Does Singulair interact with common cold medicines?
Most over-the-counter cold remedies are safe, but avoid combining with drugs that strongly induce liver enzymes (e.g., certain antifungals).
Can I take Singulair while pregnant?
Montelukast is classified as Category B in Singapore, indicating no proven risk in animal studies; however, discuss any medication use with your obstetrician.
What should I do if I forget to take my dose for several days?
Resume the regular once-daily schedule; no loading dose is required. Monitor asthma control and contact a healthcare professional if symptoms worsen.
Are there any foods I must avoid while on Singulair?
There are no specific dietary restrictions, but maintaining a balanced diet supports overall respiratory health.
How long can I stay on Singulair?
It can be used long-term as part of an asthma or allergy management plan, provided regular clinical review confirms continued benefit.
Is a blood test required before starting Singulair?
Routine testing is not mandatory, but baseline liver function may be checked in patients with pre-existing liver disease.

Reviews
Started on the 10mg about three weeks ago for my persistent nighttime cough and exercise-induced asthma. The breathing is definitely better, no doubt. But the anxiety hit me like a truck. I feel ridiculously wired, and the dreams are insane-super vivid, almost exhausting. My hack? I try taking it at 5 PM instead of before bed. It seems to soften the restless leg syndrome just enough to actually fall asleep.
Been on the 5mg chewable for my 7-year-old son, Kenzo, who has bad seasonal allergies and mild asthma. It works wonders for preventing the throat tightness we used to deal with. The tradeoff is definitely mood-related. He gets snappy and sometimes seems hyper-focused on weird things. Doctor insists it's fine, but parental intuition says otherwise. We try giving it alongside a light snack of yogurt, seems to keep the stomach issues away.
This is my fourth month on Montelukast, 10mg daily. It completely cleared my chronic rhinitis that refused to go away with just antihistamines. I breathe perfectly now, even when the haze particulate matter is high. The dark side? I have this low-grade, persistent headache that Tylenol barely touches. I've found that if I drink a ridiculously large glass of water within an hour of taking the pill, the headache is slightly less intense. Worth it for the clear sinuses.
I took it for three months for severe EIB (Exercise Induced Bronchospasm). My endurance improved substantially! I could actually finish my runs without needing the rescue inhaler every 15 minutes. However, the side effects were too bizarre to sustain. I felt depressed, really withdrawn, and started having these creepy "brain zaps" when I tried to look up suddenly. I stopped cold turkey, which the internet says is a mistake, but I couldn't handle the mental fog anymore.
Just switched to 4mg chewables for my severe allergic rhinitis because claritin gave me dry eye. The first two weeks were rough. Fatigue was extreme; I couldn't wake up fully until 10 AM. It's starting to level out now, and the post-nasal drip is finally gone. If you are struggling with the drowsy period, try splitting the dose in half-2mg in the afternoon, 2mg right before bed. It seems to break the brain fog cycle without losing effectiveness.
I've been taking this for years, 10mg every night, specifically to prevent bronchitis flare-ups related to my mild asthma. It works flawlessly as a preventative. The secret is discipline-never miss a pill. I learned early on to never take it with coffee or any caffeine source near bedtime; it somehow amplified the restless leg syndrome tenfold. Just warm milk or tea, minimum 3 hours before taking it. Stabilizes my sleep mostly, but the vivid dreaming never completely goes away.
Montelukast helped my lungs wonderfully, but it ruined my mood. I felt so flat, so unmotivated, like everything was pointless. My allergies were non-existent, my lungs were clear, but I barely wanted to leave the house. I tried taking it every other day but the asthma symptoms came creeping back immediately. It's a tough decision: clear breathing or clear mind. I'm currently trying half-dose (5mg) to see if I can maintain the asthma control without the emotional numbness.
Initially started on 10mg and the nightmares were truly terrible, like waking up shouting. Doctor lowered me to 5mg and it has been much more tolerable, and thankfully, still effective for controlling my severe dust mite allergy that causes wheezing. It's not a fast-acting drug, you have to wait patiently for a month to see the full effect, but it’s worth the wait if you can manage the initial fatigue. Tip: Always take it on a full stomach; it cuts down on the heartburn.
