Montelukast: What It Is, How It Works and When to Use It
If you’ve been prescribed a white tablet called montelukast, you’re probably dealing with asthma, allergic rhinitis, or both. It belongs to a class called leukotriene receptor antagonists, which means it blocks chemicals that cause airway swelling and mucus. The result? Easier breathing and fewer night‑time sniffles.
When to Take Montelukast
Most doctors recommend a once‑daily dose, usually in the evening. Taking it at the same time each day helps keep blood levels steady. If you have asthma that flares up at night, the evening dose can cut down on wheezing while you sleep. For allergic rhinitis, you can start the tablet a week before allergy season and keep it going throughout.
Don’t crush or chew the tablet unless your pharmacy gives you a chewable version. Swallow it with water and store it in a cool, dry place. If you miss a dose, take it as soon as you remember—unless it’s close to your next scheduled dose, then just skip the missed one.
Common Side Effects and What to Watch For
Montelukast is generally well‑tolerated, but a few people notice mild headaches, stomach upset, or a slight change in taste. More serious reactions—like mood swings, hallucinations, or a rash—are rare but need immediate medical attention. If you notice any unusual behavior or severe skin changes, call your doctor right away.
Because the drug can affect the immune system, keep an eye on any signs of infection such as fever or sore throat. And if you’re pregnant or breastfeeding, discuss the risks with your healthcare provider before starting.
Drug interactions aren’t a huge concern, but tell your pharmacist about every medication you take, especially other asthma inhalers, antibiotics, or blood thinners. Montelukast can sometimes boost the effect of certain antidepressants, so a quick check can avoid surprises.
For those who prefer a non‑tablet form, a chewable version for kids (5‑12 years) is available. The dosage differs, so never swap a chewable for an adult tablet without doctor approval.
When it comes to buying montelukast, stick to reputable pharmacies—online or brick‑and‑mortar. Look for a valid prescription, a clear return policy, and secure payment options. Avoid sites that promise “no prescription needed” or unusually low prices; they often sell counterfeit meds.
Finally, remember that montelukast isn’t a rescue inhaler. It won’t stop a sudden asthma attack. Keep your rescue inhaler handy and use montelukast as part of a long‑term plan approved by your doctor.
