Singulair (Montelukast) – What It Is and How It Helps

If you’ve been prescribed Singulair, you probably have asthma or allergic rhinitis and are looking for a daily pill that keeps symptoms in check. Singulair’s generic name is montelukast, and it belongs to a class of drugs called leukotriene receptor antagonists. In plain language, it blocks chemicals called leukotrienes that cause airway swelling, mucus, and sneezing.

Because it’s a tablet taken once a day, Singulair can be easier to fit into a busy schedule than inhalers that need multiple doses. It’s not a rescue inhaler, so you still need one on hand for sudden attacks, but for daily control it works well for many people.

Who Should Consider Singulair?

Doctors usually recommend Singulair for:

• Adults and teens (15+) with mild‑to‑moderate persistent asthma.
• Kids 6‑14 years old with asthma that isn’t fully controlled by inhaled steroids.
• Anyone with seasonal or perennial allergic rhinitis (hay fever).
• People who have trouble using inhalers correctly.

If you have a history of severe liver disease, your doctor might avoid Singulair or monitor liver enzymes closely. Always discuss your full medical history before starting.

How to Take It – Dosage Made Simple

Singulair comes in 4 mg, 5 mg, and 10 mg tablets. The usual doses are:

• Adults & teens (15+): 10 mg once daily, preferably in the evening.
• Children 6‑14 years: 5 mg once daily (or 4 mg if prescribed for allergies only).
• Children 2‑5 years: 4 mg once daily (only for allergic rhinitis, not asthma).

Swallow the tablet whole with water. Don’t crush or chew it; doing so can affect how the medicine is absorbed.

If you miss a dose, take it as soon as you remember – but only if it’s still the same day. If it’s already near bedtime, just skip it and resume the regular schedule the next day. Never double up.

Common Side Effects – What to Watch For

Most people tolerate Singulair well, but some may notice mild issues:

• Headache
• Stomach upset or nausea
• Dry mouth
• Feeling tired or drowsy

Serious side effects are rare but can include mood changes, anxiety, depression, or even suicidal thoughts. If you feel unusually sad, irritable, or have thoughts of self‑harm, call your healthcare provider right away. This warning applies to anyone, regardless of age.

Drug Interactions and Safety Tips

Singulair doesn’t have many strong interactions, but a few medicines can affect it:

• Phenobarbital, rifampin, or other enzyme‑inducing drugs may lower montelukast levels.
• Antifungal meds like ketoconazole can raise levels slightly.

Always list every prescription, over‑the‑counter, and herbal product you’re taking when you start Singulair. If you’re pregnant, breastfeeding, or planning to become pregnant, discuss the risks and benefits with your doctor – the data suggest it’s generally safe, but individual factors matter.

Quick FAQ

Can I use Singulair with my inhaler? Yes. Singulair is a controller medication; you still need a rescue inhaler for sudden symptoms.

Do I need regular blood tests? Not usually, unless you have liver issues or your doctor wants to monitor for rare side effects.

Is there a brand‑name vs. generic difference? No. The generic montelukast works the same as the brand Singulair and is usually cheaper.

In short, Singulair offers a convenient once‑daily option for many with asthma or allergies. Take it as directed, keep an eye on any mood changes, and stay in touch with your healthcare provider to make sure it’s the right fit for you.
